+ *   - Redo a previous undo with `stack.redo()`;

+# - Only works for ActiveRecord models
+# - relative_position integer field must present on the model
+# - This module uses GROUP BY: the model should have a parent relation, example: project -> issues, project is the parent relation (issues table has a parent_id column)

+
+However, every time you merge a merge request immediately, it could affect the
+existing merge train to be reconstructed, specifically, it regenerates expected
+merge commits and pipelines. This means, merging immediately essentially wastes
+CI resources.
+
+## Troubleshooting
+
+### Merge request dropped from the merge train immediately
+
+If a merge request is not mergeable (for example, it's WIP, there is a merge
+conflict, etc), your merge request will be dropped from the merge train automatically.
+
+In these cases, the reason for dropping the merge request is in the **system notes**.
+
+To check the reason:
+
+1. Open the merge request that was dropped from the merge train.
+1. Open the **Discussion** tab.
+1. Find a system note that includes either:
+   - The text **... removed this merge request from the merge train because ...**
+   - **... aborted this merge request from the merge train because ...**
+   The reason is given in the text after the **because ...** phrase.

+is available as a workaround in your workflow. This is the most recommended

+### How to prepare for speedy database reviews
+
+In order to make reviewing easier and therefore faster, please consider preparing a comment
+and details for a database reviewer:
+
+- Provide queries in SQL form rather than ActiveRecord.
+- Format any queries with a SQL query formatter, for example with [sqlformat.darold.net](http://sqlformat.darold.net).
+- Consider providing query plans via a link to [explain.depesz.com](https://explain.depesz.com) or another tool instead of textual form.
+- For query changes, it is best to provide the SQL query along with a plan *before* and *after* the change. This helps to spot differences quickly.
+- When providing query plans, make sure to use good parameter values, so that the query executed is a good example and also hits enough data. Usually, the `gitlab-org` namespace (`namespace_id = 9970`) and the `gitlab-org/gitlab-ce` project (`project_id = 13083`) provides enough data to serve as a good example.

+
+GitLab ensures that the Markdown used across all documentation is consistent, as
+well as easy to review and maintain, by testing documentation changes with
+[Markdownlint (mdl)](https://github.com/markdownlint/markdownlint). This lint test
+checks many common problems with Markdown, and fails when any document has an issue
+with Markdown formatting that may cause the page to render incorrectly within GitLab.
+It will also fail when a document is using non-standard Markdown (which may render
+correctly, but is not the current standard in GitLab documentation).
+
+Each formatting issue that mdl checks has an associated [rule](https://github.com/markdownlint/markdownlint/blob/master/docs/RULES.md),

+# Filtering by label
+
+## Introduction
+
+GitLab has [labels](../user/project/labels.md) that can be assigned to issues,
+merge requests, and epics. Labels on those objects are a many-to-many relation
+through the polymorphic `label_links` table.
+
+To filter these objects by multiple labels - for instance, 'all open
+issues with the label ~Plan and the label ~backend' - we generate a
+query containing a `GROUP BY` clause. In a simple form, this looks like:
+
+```sql
+SELECT
+    issues.*
+FROM
+    issues
+    INNER JOIN label_links ON label_links.target_id = issues.id
+        AND label_links.target_type = 'Issue'
+    INNER JOIN labels ON labels.id = label_links.label_id
+WHERE
+    issues.project_id = 13083
+    AND (issues.state IN ('opened'))
+    AND labels.title IN ('Plan',
+        'backend')
+GROUP BY
+    issues.id
+HAVING (COUNT(DISTINCT labels.title) = 2)
+ORDER BY
+    issues.updated_at DESC,
+    issues.id DESC
+LIMIT 20 OFFSET 0
+```
+
+In particular, note that:
+
+1. We `GROUP BY issues.id` so that we can ...
+2. Use the `HAVING (COUNT(DISTINCT labels.title) = 2)` condition to ensure that
+   all matched issues have both labels.
+
+This is more complicated than is ideal. It makes the query construction more
+prone to errors (such as
+[gitlab-org/gitlab-ce#15557](https://gitlab.com/gitlab-org/gitlab-ce/issues/15557)).
+
+## Attempt A: WHERE EXISTS
+
+### Attempt A1: use multiple subqueries with WHERE EXISTS
+
+In
+[gitlab-org/gitlab-ce#37137](https://gitlab.com/gitlab-org/gitlab-ce/issues/37137)
+and its associated merge request
+[gitlab-org/gitlab-ce!14022](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/14022),
+we tried to replace the `GROUP BY` with multiple uses of `WHERE EXISTS`. For the
+example above, this would give:
+
+```sql
+WHERE (EXISTS (
+        SELECT
+            TRUE
+        FROM
+            label_links
+            INNER JOIN labels ON labels.id = label_links.label_id
+        WHERE
+            labels.title = 'Plan'
+            AND target_type = 'Issue'
+            AND target_id = issues.id))
+AND (EXISTS (
+        SELECT
+            TRUE
+        FROM
+            label_links
+            INNER JOIN labels ON labels.id = label_links.label_id
+        WHERE
+            labels.title = 'backend'
+            AND target_type = 'Issue'
+            AND target_id = issues.id))
+```
+
+While this worked without schema changes, and did improve readability somewhat,
+it did not improve query performance.
+
+## Attempt B: Denormalize using an array column
+
+Having [removed MySQL support in GitLab
+12.1](https://about.gitlab.com/2019/06/27/removing-mysql-support/), using
+[Postgres's arrays](https://www.postgresql.org/docs/9.6/arrays.html) became more
+tractable as we didn't have to support two databases. We discussed denormalizing
+the `label_links` table for querying in
+[gitlab-org/gitlab-ce#49651](https://gitlab.com/gitlab-org/gitlab-ce/issues/49651),
+with two options: label IDs and titles.
+
+We can think of both of those as array columns on `issues`, `merge_requests`,
+and `epics`: `issues.label_ids` would be an array column of label IDs, and
+`issues.label_titles` would be an array of label titles.
+
+These array columns can be complemented with [GIN
+indexes](https://www.postgresql.org/docs/9.6/gin-intro.html) to improve
+matching.
+
+### Attempt B1: store label IDs for each object
+
+This has some strong advantages over titles:
+
+1. Unless a label is deleted, or a project is moved, we never need to
+   bulk-update the denormalized column.
+2. It uses less storage than the titles.
+
+Unfortunately, our application design makes this hard. If we were able to query
+just by label ID easily, we wouldn't need the `INNER JOIN labels` in the initial
+query at the start of this document. GitLab allows users to filter by label
+title across projects and even across groups, so a filter by the label ~Plan may
+include labels with multiple distinct IDs.
+
+We do not want users to have to know about the different IDs, which means that
+given this data set:
+
+| Project | ~Plan label ID | ~backend label ID |
+| ---     | ---            | ---               |
+| A       | 11             | 12                |
+| B       | 21             | 22                |
+| C       | 31             | 32                |
+
+We would need something like:
+
+```sql
+WHERE
+    label_ids @> ARRAY[11, 12]
+    OR label_ids @> ARRAY[21, 22]
+    OR label_ids @> ARRAY[31, 32]
+```
+
+This can get even more complicated when we consider that in some cases, there
+might be two ~backend labels - with different IDs - that could apply to the same
+object, so the number of combinations would balloon further.
+
+### Attempt B2: store label titles for each object
+
+From the perspective of updating the labelable object, this is the worst
+option. We have to bulk update the objects when:
+
+1. The objects are moved from one project to another.
+1. The project is moved from one group to another.
+1. The label is renamed.
+1. The label is deleted.
+
+It also uses much more storage. Querying is simple, though:
+
+```sql
+WHERE
+    label_titles @> ARRAY['Plan', 'backend']
+```
+
+And our [tests in
+gitlab-org/gitlab-ce#49651](https://gitlab.com/gitlab-org/gitlab-ce/issues/49651#note_188777346)
+showed that this could be fast.
+
+However, at present, the disadvantages outweigh the advantages.
+
+## Conclusion
+
+We have yet to find a method that is demonstratably better than the current
+method, when considering:
+
+1. Query performance.
+1. Readability.
+1. Ease of maintaining schema consistency.

+### Table-Driven Tests
+
+Using [Table-Driven Tests](https://github.com/golang/go/wiki/TableDrivenTests)
+is generally good practice when you have multiple entries of
+inputs/outputs for the same function. Below are some guidelines one can
+follow when writing table-driven test. These guidelines are mostly
+extracted from Go standard library source code. Keep in mind it's OK not
+to follow these guidelines when it makes sense.
+
+#### Defining test cases
+
+Each table entry is a complete test case with inputs and expected
+results, and sometimes with additional information such as a test name
+to make the test output easily readable.
+
+- [Define a slice of anonymous struct](https://github.com/golang/go/blob/50bd1c4d4eb4fac8ddeb5f063c099daccfb71b26/src/encoding/csv/reader_test.go#L16)

+
+#### Contents of the test case
+
+- Ideally, each test case should have a field with a unique identifier
+  to use for naming subtests. In the Go standard library, this is commonly the
+  `name string` field.
+- Use `want`/`expect`/`actual` when you are specifcing something in the
+  test case that will be used for assertion.
+
+#### Variable names
+
+- Each table-driven test map/slice of struct can be named `tests`.
+- When looping through `tests` the anonymous struct can be referred
+  to as `tt` or `tc`.
+- The description of the test can be referred to as
+  `name`/`testName`/`tn`.

+# Shell scripting standards and style guidelines
+
+## Overview
+
+GitLab consists of many various services and sub-projects. The majority of
+their backend code is written in [Ruby](https://www.ruby-lang.org) and
+[Go](https://golang.org). However, some of them use shell scripts for
+automation of routine system administration tasks like deployment,
+installation, etc. It's being done either for historical reasons or as an effort
+to minimize the dependencies, for instance, for Docker images.
+
+This page aims to define and organize our shell scripting guidelines,
+based on our various experiences. All shell scripts across GitLab project
+should be eventually harmonized with this guide. If there are any per-project
+deviations from this guide, they should be described in the
+`README.md` or `PROCESS.md` file for such a project.
+
+### Avoid using shell scripts
+
+CAUTION: **Caution:**
+This is a must-read section.
+
+Having said all of the above, we recommend staying away from shell scripts
+as much as possible. A language like Ruby or Python (if required for
+consistency with codebases that we leverage) is almost always a better choice.
+The high-level interpreted languages have more readable syntax, offer much more
+mature capabilities for unit-testing, linting, and error reporting.  
+Use shell scripts only if there's a strong restriction on project's
+dependencies size or any other requirements that are more important
+in a particular case.
+
+## Scope of this guide
+
+According to the [GitLab installation requirements](../../install/requirements.md),
+this guide covers only those shells that are used by
+[supported Linux distributions](../../install/requirements.md#supported-linux-distributions),
+that is:
+
+- [POSIX Shell](https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html)
+- [Bash](https://www.gnu.org/software/bash/)
+
+## Shell language choice
+
+- When you need to reduce the dependencies list, use what's provided by the environment. For example, for Docker images it's `sh` from `alpine` which is the base image for most of our tool images.
+- Everywhere else, use `bash` if possible. It's more powerful than `sh` but still a widespread shell.
+
+## Code style and format
+
+This section describes the tools that should be made a mandatory part of
+a project's CI pipeline if it contains shell scripts. These tools
+automate shell code formatting, checking for errors or vulnerabilities, etc.   
+
+### Linting
+
+We're using the [ShellCheck](https://www.shellcheck.net/) utility in its default configuration to lint our
+shell scripts. 
+
+All projects with shell scripts should use this GitLab CI/CD job:
+
+```yaml
+shell check:
+  image: koalaman/shellcheck-alpine
+  stage: test
+  before_script:
+    - shellcheck --version
+  script:
+    - shellcheck scripts/**/*.sh # path to your shell scripts
+```
+
+TIP: **Tip:**
+By default, ShellCheck will use the [shell detection](https://github.com/koalaman/shellcheck/wiki/SC2148#rationale)
+to determine the shell dialect in use. If the shell file is out of your control and ShellCheck cannot
+detect the dialect, use `-s` flag to specify it: `-s sh` or `-s bash`.
+
+### Formatting
+
+It's recommended to use the [shfmt](https://github.com/mvdan/sh#shfmt) tool to maintain consistent formatting.
+We format shell scripts according to the [Google Shell Style Guide](https://google.github.io/styleguide/shell.xml),
+so the following `shfmt` invocation should be applied to the project's script files:
+
+```bash
+shfmt -i 2 -ci scripts/**/*.sh
+```
+
+TIP: **Tip:**
+By default, shfmt will use the [shell detection](https://github.com/mvdan/sh#shfmt) similar to one of ShellCheck
+and ignore files starting with a period. To override this, use `-ln` flag to specify the shell dialect:
+`-ln posix` or `-ln bash`.
+
+NOTE: **Note:**
+Currently, the `shfmt` tool [is not shipped](https://github.com/mvdan/sh/issues/68) as a Docker image containing
+a Linux shell. This makes it impossible to use the [official Docker image](https://hub.docker.com/r/mvdan/shfmt)
+in GitLab Runner. This [may change](https://github.com/mvdan/sh/issues/68#issuecomment-507721371) in future.
+
+## Testing
+
+NOTE: **Note:**
+This is a work in progress.
+
+It is an [ongoing effort](https://gitlab.com/gitlab-org/gitlab-ce/issues/64016) to evaluate different tools for the
+automated testing of shell scripts (like [BATS](https://github.com/sstephenson/bats)).  
+
+## Code Review
+
+The code review should be performed according to:
+
+- [ShellCheck Checks list](https://github.com/koalaman/shellcheck/wiki/Checks)
+- [Google Shell Style Guide](https://google.github.io/styleguide/shell.xml)
+- [Shfmt formatting caveats](https://github.com/mvdan/sh#caveats)
+
+However, the recommended course of action is to use the aforementioned
+tools and address reported offenses. This should eliminate the need
+for code review.

-- Block user: Blocks the reported user from the instance and does not remove the abuse report from the list.
-- Remove report: Removes the abuse report from the list and does not restrict the access for the reported user.

+- Expose its detection logic.
+- Handle its execution.
+- Convert its output to the common format.
+
+This is achieved by implementing the [common API](https://gitlab.com/gitlab-org/security-products/analyzers/common).
+
+SAST supports the following official analyzers:
+
+- [Bandit](https://gitlab.com/gitlab-org/security-products/analyzers/bandit)
+- [Brakeman](https://gitlab.com/gitlab-org/security-products/analyzers/brakeman)
+- [ESLint (Javascript)](https://gitlab.com/gitlab-org/security-products/analyzers/eslint)
+- [SpotBugs with the Find Sec Bugs plugin (Ant, Gradle and wrapper, Grails, Maven and wrapper, SBT)](https://gitlab.com/gitlab-org/security-products/analyzers/spotbugs)
+- [Flawfinder](https://gitlab.com/gitlab-org/security-products/analyzers/flawfinder)
+- [Gosec](https://gitlab.com/gitlab-org/security-products/analyzers/gosec)
+- [NodeJsScan](https://gitlab.com/gitlab-org/security-products/analyzers/nodejs-scan)
+- [PHP CS security-audit](https://gitlab.com/gitlab-org/security-products/analyzers/phpcs-security-audit)
+- [Secrets (Gitleaks, TruffleHog & Diffence secret detectors)](https://gitlab.com/gitlab-org/security-products/analyzers/secrets)
+- [Security Code Scan (.NET)](https://gitlab.com/gitlab-org/security-products/analyzers/security-code-scan)
+- [TSLint (Typescript)](https://gitlab.com/gitlab-org/security-products/analyzers/tslint)
+- [Sobelow (Elixir Phoenix)](https://gitlab.com/gitlab-org/security-products/analyzers/sobelow)
+
+The analyzers are published as Docker images that SAST will use to launch
+dedicated containers for each analysis.
+
+SAST is pre-configured with a set of **default images** that are maintained by
+GitLab, but users can also integrate their own **custom images**.
+
+## Official default analyzers
+
+Any custom change to the official analyzers can be achieved by using an
+[environment variable in your `.gitlab-ci.yml`](index.md#customizing-the-sast-settings).
+
+### Using a custom Docker mirror
+
+You can switch to a custom Docker registry that provides the official analyzer
+images under a different prefix. For instance, the following instructs
+SAST to pull `my-docker-registry/gl-images/bandit`
+instead of `registry.gitlab.com/gitlab-org/security-products/analyzers/bandit`.
+In `.gitlab-ci.yml` define:
+
+```yaml
+include:
+  template: SAST.gitlab-ci.yml
+
+variables:
+  SAST_ANALYZER_IMAGE_PREFIX: my-docker-registry/gl-images
+```
+
+This configuration requires that your custom registry provides images for all
+the official analyzers.
+
+### Selecting specific analyzers
+
+You can select the official analyzers you want to run. Here's how to enable
+`bandit` and `flawfinder` while disabling all the other default ones.
+In `.gitlab-ci.yml` define:
+
+```yaml
+include:
+  template: SAST.gitlab-ci.yml
+
+variables:
+  SAST_DEFAULT_ANALYZERS: "bandit,flawfinder"
+```
+
+`bandit` runs first. When merging the reports, SAST will
+remove the duplicates and will keep the `bandit` entries.
+
+### Disabling default analyzers
+
+Setting `SAST_DEFAULT_ANALYZERS` to an empty string will disable all the official
+default analyzers. In `.gitlab-ci.yml` define:
+
+```yaml
+include:
+  template: SAST.gitlab-ci.yml
+
+variables:
+  SAST_DEFAULT_ANALYZERS: ""
+```
+
+That's needed when one totally relies on [custom analyzers](#custom-analyzers).
+
+## Custom Analyzers
+
+You can provide your own analyzers as a comma separated list of Docker images.
+Here's how to add `analyzers/csharp` and `analyzers/perl` to the default images:
+In `.gitlab-ci.yml` define:
+
+```yaml
+include:
+  template: SAST.gitlab-ci.yml
+
+variables:
+  SAST_ANALYZER_IMAGES: "my-docker-registry/analyzers/csharp,amy-docker-registry/analyzers/perl"
+```
+
+The values must be the full path to the container registry images,
+like what you would feed to the `docker pull` command.
+
+NOTE: **Note:**
+This configuration doesn't benefit from the integrated detection step.
+SAST has to fetch and spawn each Docker image to establish whether the
+custom analyzer can scan the source code.

+
+#### Docker images
+
+The following are Docker image-related variables.
+
+| Environment variable          | Description                                                                    |

+
+### Vulnerability filters
+
+Some analyzers make it possible to filter out vulnerabilities under a given threshold.
+
+| `SAST_BANDIT_EXCLUDED_PATHS`  | -   | comma-separated list of paths to exclude from scan. Uses Python's [`fnmatch` syntax](https://docs.python.org/2/library/fnmatch.html) |
+| `SAST_BRAKEMAN_LEVEL`   |         1 | Ignore Brakeman vulnerabilities under given confidence level. Integer, 1=Low 3=High. |
+| `SAST_FLAWFINDER_LEVEL` |         1 | Ignore Flawfinder vulnerabilities under given risk level. Integer, 0=No risk, 5=High risk. |
+| `SAST_GITLEAKS_ENTROPY_LEVEL` | 8.0 | Minimum entropy for secret detection. Float, 0.0 = low, 8.0 = high. |
+| `SAST_GOSEC_LEVEL`      |         0 | Ignore gosec vulnerabilities under given confidence level. Integer, 0=Undefined, 1=Low, 1=Medium, 3=High. |
+| `SAST_EXCLUDED_PATHS`   |   -        | Exclude vulnerabilities from output based on the paths. This is a comma-separated list of patterns. Patterns can be globs, file or folder paths. Parent directories will also match patterns. |
+
+### Timeouts
+
+The following variables configure timeouts.
+
+| `SAST_DOCKER_CLIENT_NEGOTIATION_TIMEOUT` |      2m | Time limit for Docker client negotiation. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". For example, "300ms", "1.5h" or "2h45m". |
+| `SAST_PULL_ANALYZER_IMAGE_TIMEOUT`       |      5m | Time limit when pulling the image of an analyzer. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". For example, "300ms", "1.5h" or "2h45m". |
+| `SAST_RUN_ANALYZER_TIMEOUT`              |     20m | Time limit when running an analyzer. Timeouts are parsed using Go's [`ParseDuration`](https://golang.org/pkg/time/#ParseDuration). Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", "h". For example, "300ms", "1.5h" or "2h45m".|

-Connect your project to Google Kubernetes Engine (GKE) or an existing Kubernetes

+GitLab provides many features with a Kubernetes integration. Kubernetes can be
+integrated with projects, but also:
+
+- [Groups](../../group/clusters/index.md).
+- [Instances](../../instance/clusters/index.md).
 
 NOTE: **Scalable app deployment with GitLab and Google Cloud Platform**
 [Watch the webcast](https://about.gitlab.com/webcast/scalable-app-deploy/) and learn how to spin up a Kubernetes cluster managed by Google Cloud Platform (GCP) in a few clicks.
 
 ## Overview
 
-With one or more Kubernetes clusters associated to your project, you can use
-[Review Apps](../../../ci/review_apps/index.md), deploy your applications, run
-your pipelines, use it with [Auto DevOps](../../../topics/autodevops/index.md),
-and much more, all from within GitLab.
+Using the GitLab project Kubernetes integration, you can:
+
+- Use [Review Apps](../../../ci/review_apps/index.md).
+- Run [pipelines](../../../ci/pipelines.md).
+- [Deploy](#deploying-to-a-kubernetes-cluster) your applications.
+- Detect and [monitor Kubernetes](#kubernetes-monitoring).
+- Use it with [Auto DevOps](#auto-devops).
+- Use [Web terminals](#web-terminals).
+- Use [Deploy Boards](#deploy-boards-premium). **(PREMIUM)**
+- Use [Canary Deployments](#canary-deployments-premium). **(PREMIUM)**
+- View [Pod logs](#pod-logs-ultimate). **(ULTIMATE)**
+
+You can also:
+
+- Connect and deploy to an [Amazon EKS cluster](eks_and_gitlab/index.html).
+- Run serverless workloads on [Kubernetes with Knative](serverless/index.md).
+
+### Deploy Boards **(PREMIUM)**
+
+GitLab's Deploy Boards offer a consolidated view of the current health and
+status of each CI [environment](../../../ci/environments.md) running on Kubernetes,
+displaying the status of the pods in the deployment. Developers and other
+teammates can view the progress and status of a rollout, pod by pod, in the
+workflow they already use without any need to access Kubernetes.
+
+[Read more about Deploy Boards](../deploy_boards.md)
+
+### Canary Deployments **(PREMIUM)**
+
+Leverage [Kubernetes' Canary deployments](https://kubernetes.io/docs/concepts/cluster-administration/manage-deployment/#canary-deployments)
+and visualize your canary deployments right inside the Deploy Board, without
+the need to leave GitLab.
+
+[Read more about Canary Deployments](../canary_deployments.md)
+
+### Pod logs **(ULTIMATE)**
+
+GitLab makes it easy to view the logs of running pods in connected Kubernetes clusters. By displaying the logs directly in GitLab, developers can avoid having to manage console tools or jump to a different interface.
+
+[Read more about Kubernetes pod logs](kubernetes_pod_logs.md)
+
+### Kubernetes monitoring
 
-There are two options when adding a new cluster to your project; either associate
-your account with Google Kubernetes Engine (GKE) so that you can [create new
-clusters](#adding-and-creating-a-new-gke-cluster-via-gitlab) from within GitLab,
-or provide the credentials to an [existing Kubernetes cluster](#adding-an-existing-kubernetes-cluster).
+Automatically detect and monitor Kubernetes metrics. Automatic monitoring of
+[NGINX ingress](../integrations/prometheus_library/nginx.md) is also supported.
+
+[Read more about Kubernetes monitoring](../integrations/prometheus_library/kubernetes.md)
+
+### Auto DevOps
+
+Auto DevOps automatically detects, builds, tests, deploys, and monitors your
+applications.
+
+To make full use of Auto DevOps(Auto Deploy, Auto Review Apps, and Auto Monitoring)
+you will need the Kubernetes project integration enabled.
+
+[Read more about Auto DevOps](../../../topics/autodevops/index.md)
+
+### Web terminals
 
 NOTE: **Note:**
-From [GitLab 11.6](https://gitlab.com/gitlab-org/gitlab-ce/issues/34758) you
-can also associate a Kubernetes cluster to your groups and from
-[GitLab 11.11](https://gitlab.com/gitlab-org/gitlab-ce/issues/39840),
-to the GitLab instance. Learn more about [group-level](../../group/clusters/index.md)
-and [instance-level](../../instance/clusters/index.md) Kubernetes clusters.
+Introduced in GitLab 8.15. You must be the project owner or have `maintainer` permissions
+to use terminals. Support is limited to the first container in the
+first pod of your environment.
+
+When enabled, the Kubernetes service adds [web terminal](../../../ci/environments.md#web-terminals)
+support to your [environments](../../../ci/environments.md). This is based on the `exec` functionality found in
+Docker and Kubernetes, so you get a new shell session within your existing
+containers. To use this integration, you should deploy to Kubernetes using
+the deployment variables above, ensuring any deployments, replica sets, and
+pods are annotated with:

+### Setting the environment scope **(PREMIUM)**
+
+When adding more than one Kubernetes cluster to your project, you need to differentiate

+[environment-specific variables](../../../ci/variables/README.md#limiting-environment-scopes-of-environment-variables-premium) work.

+The default environment scope is `*`, which means all jobs, regardless of their
+environment, will use that cluster. Each scope can only be used by a single
+cluster in a project, and a validation error will occur if otherwise.
+Also, jobs that don't have an environment keyword set will not be able to access any cluster.
+
+For example, let's say the following Kubernetes clusters exist in a project:
+
+| Cluster     | Environment scope |
+| ----------- | ----------------- |
+| Development | `*`               |
+| Staging     | `staging`         |
+| Production  | `production`      |
+
+And the following environments are set in [`.gitlab-ci.yml`](../../../ci/yaml/README.md):
+
+```yaml
+stages:
+- test
+- deploy
+
+test:
+  stage: test
+  script: sh test

+
+deploy to production:
+  stage: deploy
+  script: make deploy
+  environment:
+    name: production
+    url: https://example.com/

+# Design Management **(PREMIUM)**
+
+> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/660) in [GitLab Premium](https://about.gitlab.com/pricing/) 12.2.
+
+CAUTION: **Warning:**
+This an __alpha__ feature and is subject to change at any time without
+prior notice.
+
+## Overview
+
+Design Management allows you to upload design assets (wireframes, mockups, etc.)
+to GitLab issues and keep them stored in one single place, accessed by the Design
+Management's page within an issue, giving product designers, product managers, and engineers a
+way to collaborate on designs over one single source of truth.
+
+You can easily share mock-ups of designs with your team, or visual regressions can be easily
+viewed and addressed.
+
+<i class="fa fa-youtube-play youtube" aria-hidden="true"></i>
+For an overview, see the video [Design Management (GitLab 12.2)](https://www.youtube.com/watch?v=CCMtCqdK_aM).
+
+## Requirements
+
+Design Management requires
+[Large File Storage (LFS)](../../../workflow/lfs/manage_large_binaries_with_git_lfs.md)
+to be enabled:
+
+- For GitLab.com, LFS is already enabled.
+- For self-managed instances, a GitLab administrator must have
+  [enabled LFS globally](../../../workflow/lfs/lfs_administration.md).
+- For both GitLab.com and self-managed instances: LFS must be enabled for the project itself.
+  If enabled globally, LFS will be enabled by default to all projects. To enable LFS on the
+  project level, navigate to your project's **Settings > General**, expand **Visibility, project features, permissions**
+  and enable **Git Large File Storage**.
+
+## Limitations
+
+- Files uploaded must have a file extension of either `png`, `jpg`, `jpeg`, `gif`, `bmp`, `tiff` or `ico`. The [`svg` extension is not yet supported](https://gitlab.com/gitlab-org/gitlab-ee/issues/12771).
+- [Designs cannot yet be deleted](https://gitlab.com/gitlab-org/gitlab-ee/issues/11089).
+- Design Management is [not yet supported in the project export](https://gitlab.com/gitlab-org/gitlab-ee/issues/11090).

+
+## Adding designs
+
+To upload design images, click the **Upload Designs** button and select images to upload.

+# Blocking merge requests **(PREMIUM)**
+
+> Introduced in GitLab Premium 12.2
+
+Blocking merge requests allow dependencies between MRs to be expressed. If a
+merge request is blocked by another MR, it cannot be merged until that blocking
+MR is itself merged.
+
+NOTE: **Note:**
+Blocking merge requests are a **PREMIUM** feature, but this restriction is only
+enforced for the blocked merge request. A merge request in a **CORE** or
+**STARTER** project can block a **PREMIUM** merge request, but not vice-versa.
+
+## Use cases
+
+* Ensure changes to a library are merged before changes to a project that
+  imports the library
+* Prevent a documentation-only merge request from being merged before the MR
+  implementing the feature to be documented
+* Require an MR updating a permissions matrix to be merged before merging an
+  MR from someone who hasn't yet been granted permissions
+
+It is common for a single logical change to span several merge requests. These
+MRs may all be in a single project, or they may be spread out across multiple
+projects, and the order in which they are merged can be significant.
+
+For example, given a project `mycorp/awesome-project` that imports a library
+at `myfriend/awesome-lib`, adding a feature in `awesome-project` may **also**
+require changes to `awesome-lib`, and so necessitate two merge requests. Merging
+the `awesome-project` MR before the `awesome-lib` one would break the `master`
+branch.
+
+The `awesome-project` MR could be [marked as WIP](work_in_progress_merge_requests.md),
+and the reason for the WIP stated included in the comments. However, this
+requires the state of the `awesome-lib` MR to be manually tracked, and doesn't
+scale well if the `awesome-project` MR depends on changes to **several** other
+projects.
+
+By marking the `awesome-project` MR as blocked on the `awesome-lib` MR instead,
+the status of the dependency is automatically tracked by GitLab, and the WIP
+state can be used to communicate the readiness of the code in each individual
+MR instead.
+
+## Configuration
+
+To continue the above example, you can configure a block when creating the
+new MR in `awesome-project` (or by editing it, if it already exists). The block
+needs to be configured on the MR that will be **blocked**, rather than on the
+**blocking** MR. There is a "Blocking merge requests" section in the form:
+
+![Blocking merge requests form control](img/edit_blocking_merge_requests.png)
+
+Anyone who can edit a merge request can change the list of blocking merge
+requests.
+
+New blocks can be added by reference, by URL, or by using autcompletion. To
+remove a block, press the "X" by its reference.
+
+As blocks can be specified across projects, it's possible that someone else has
+added a block for a merge request in a project you don't have access to. These
+are shown as a simple count:
+
+![Blocking merge requests form control with inaccessible MRs](img/edit_blocking_merge_requests_inaccessible.png)
+
+If necessary, you can remove all the blocks like this by pressing the "X", just
+as you would for a single, visible block.
+
+Once you're finished, press the "Save changes" button to submit the request, or
+"Cancel" to return without making any changes.
+
+The list of configured blocks, and the status of each one, is shown in the merge
+request widget:
+
+![Blocking merge requests in merge request widget](img/show_blocking_merge_requests_in_mr_widget.png)
+
+Until all blocking merge requests have, themselves, been merged, the "Merge"
+button will be disabled. In particular, note that **closed** merge requests
+still block their dependents - it is impossible to automatically determine if
+merge requests that were blocked by that MR when it was open, are still blocked
+when it is closed.
+
+If a merge request has been closed **and** the block is no longer relevant, it
+must be removed as a blocking MR, following the instructions above, before
+merge.
+
+## Limitations
+
+* API support: [gitlab-ee#12551](https://gitlab.com/gitlab-org/gitlab-ee/issues/12551)
+* Blocking relationships are not preserved across project export/import: [gitlab-ee#12549](https://gitlab.com/gitlab-org/gitlab-ee/issues/12549)
+* Complex merge order dependencies are not supported: [gitlab-ee#11393](https://gitlab.com/gitlab-org/gitlab-ee/issues/11393)
+
+The last item merits a little more explanation. Blocking merge requests can be
+described as a graph of dependencies. The simplest possible graph has one
+merge request blocking another:
+
+```mermaid
+graph LR;
+    myfriend/awesome-lib!10-->mycorp/awesome-project!100;
+```
+
+A more complex (and still supported) graph might have several MRs blocking
+another from being merged:
+
+```mermaid
+graph LR;
+    myfriend/awesome-lib!10-->mycorp/awesome-project!100;
+    herfriend/another-lib!1-->mycorp/awesome-project!100;
+```
+
+We also support one MR blocking several others from being merged:
+
+```mermaid
+graph LR;
+    herfriend/another-lib!1-->myfriend/awesome-lib!10;
+    herfriend/another-lib!1-->mycorp/awesome-project!100;
+```
+
+What is **not** supported is a "deep", or "nested" graph of dependencies, e.g.:
+
+```mermaid
+graph LR;
+    herfriend/another-lib!1-->myfriend/awesome-lib!10;
+    myfriend/awesome-lib!10-->mycorp/awesome-project!100;
+```
+
+In this example, `myfriend/awesome-lib!10` would be blocked from being merged by
+`herfriend/another-lib!1`, and would also block `mycorp/awesome-project!100`
+from being merged. This is **not** yet supported.

+## Configuring jobs using variables
 
-First of all, you need to define a job in your `.gitlab-ci.yml` file that generates the
-[Code Quality report artifact](../../../ci/yaml/README.md#artifactsreportscodequality-starter).
+The Code Quality job supports environment variables that users can set to
+configure job execution at runtime.
 
-The Code Quality report artifact is a subset of the
-[Code Climate spec](https://github.com/codeclimate/spec/blob/master/SPEC.md#data-types).
-It must be a JSON file containing an array of objects with the following properties:
+For a list of available environment variables, see
+[Environment variables](https://gitlab.com/gitlab-org/security-products/codequality/blob/master/README.md#environment-variables).
+
+## Implementing a custom tool
+
+It's possible to have a custom tool provide Code Quality reports in GitLab. To
+do this:
+
+1. Define a job in your `.gitlab-ci.yml` file that generates the
+   [Code Quality report
+   artifact](../../../ci/yaml/README.md#artifactsreportscodequality-starter).
+1. Configure your tool to generate the Code Quality report artifact as a JSON
+   file that implements subset of the [Code Climate
+   spec](https://github.com/codeclimate/spec/blob/master/SPEC.md#data-types).
+
