+
+The `GIT_CHECKOUT` variable can be used when the `GIT_STRATEGY` is set to either
+`clone` or `fetch` to specify whether a `git checkout` should be run. If not
+specified, it defaults to true. Like `GIT_STRATEGY`, it can be set in either the
+global [`variables`](#variables) section or the [`variables`](#job-variables)

+- when doing `fetch` - update the repository and leave working copy on
+  the current revision,
+- when doing `clone` - clone the repository and leave working copy on the

+Having this setting set to `true` will mean that for both `clone` and `fetch`
+strategies the Runner will checkout the working copy to a revision related

+# Serializing Data
+
+**Summary:** don't store serialized data in the database, use separate columns
+and/or tables instead.
+
+Rails makes it possible to store serialized data in JSON, YAML or other formats.
+Such a field can be defined as follows:
+
+```ruby
+class Issue < ActiveRecord::Model
+  serialize :custom_fields
+end
+```
+
+While it may be tempting to store serialized data in the database there are many
+problems with this. This document will outline these problems and provide an
+alternative.
+
+## Serialized Data Is Less Powerful
+
+When using a relational database you have the ability to query individual
+fields, change the schema, index data and so forth. When you use serialized data
+all of that becomes either very difficult or downright impossible. While
+PostgreSQL does offer the ability to query JSON fields it is mostly meant for
+very specialized use cases, and not for more general use. If you use YAML in
+turn there's no way to query the data at all.
+
+## Waste Of Space
+
+Storing serialized data such as JSON or YAML will end up wasting a lot of space.
+This is because these formats often include additional characters (e.g. double
+quotes or newlines) besides the data that you are storing.
+
+## Difficult To Manage
+
+There comes a time where you will need to add a new field to the serialized
+data, or change an existing one. Using serialized data this becomes difficult
+and very time consuming as the only way of doing so is to re-write all the
+stored values. To do so you would have to:
+
+1. Retrieve the data
+1. Parse it into a Ruby structure
+1. Mutate it
+1. Serialize it back to a String
+1. Store it in the database
+
+On the other hand, if one were to use regular columns adding a column would be
+as easy as this:
+
+```sql
+ALTER TABLE table_name ADD COLUMN column_name type;
+```
+
+Such a query would take very little to no time and would immediately apply to
+all rows, without having to re-write large JSON or YAML structures.
+
+Finally, there comes a time when the JSON or YAML structure is no longer
+sufficient and you need to migrate away from it. When storing only a few rows
+this may not be a problem, but when storing millions of rows such a migration
+can easily take hours or even days to complete.
+
+## Relational Databases Are Not Document Stores
+
+When storing data as JSON or YAML you're essentially using your database as if
+it were a document store (e.g. MongoDB), except you're not using any of the
+powerful features provided by a typical RDBMS _nor_ are you using any of the
+features provided by a typical document store (e.g. the ability to index fields
+of documents with variable fields). In other words, it's a waste.
+
+## Consistent Fields
+
+One argument sometimes made in favour of serialized data is having to store
+widely varying fields and values. Sometimes this is truly the case, and then
+perhaps it might make sense to use serialized data. However, in 99% of the cases
+the fields and types stored tend to be the same for every row. Even if there is
+a slight difference you can still use separate columns and just not set the ones
+you don't need.
+
+## The Solution
+
+The solution is very simple: just use separate columns and/or separate tables.
+This will allow you to use all the features provided by your database, it will
+make it easier to manage and migrate the data, you'll conserve space, you can
+index the data efficiently and so forth.

+#### Preserving Source IPs
+

+
+See the [Kubernetes documentation](https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-typeloadbalancer) for more information.
+
+To fix this you can add the following service annotation to your `values.yaml`
+
+```yaml
+## For minikube, set this to NodePort, elsewhere use LoadBalancer
+## ref: http://kubernetes.io/docs/user-guide/services/#publishing-services---service-types
+##
+serviceType: LoadBalancer
+
+## Optional annotations for gitlab service.

+  service.beta.kubernetes.io/external-traffic: "OnlyLocal"

+
+>**Note:**
+If you are using the ingress routing, you will likely also need to specify the annotation on the service for the ingress
+controller. For `nginx-ingress` you can check the
+[configuration documentation](https://github.com/kubernetes/charts/blob/master/stable/nginx-ingress/README.md#configuration)
+on how to add the annotation to the  `controller.service.annotations` array.
+
+>**Note:**
+When using the `nginx-ingress` controller on Google Container Engine (GKE), and using the `external-traffic` annotation,
+you will need to additionally set the `controller.kind` to be DaemonSet. Otherwise only pods running on the same node
+as the nginx controller will be able to reach GitLab. This may result in pods within your cluster not being able to reach GitLab.
+See the [Kubernetes documentation](https://kubernetes.io/docs/tutorials/services/source-ip/#source-ip-for-services-with-typeloadbalancer) and

+it has a minimum requirement of node v4.3.0.
+
+You can check which version you are running with `node -v`. If you are running

+can find instructions to install from community maintained packages or compile
+from source at the nodejs.org website.
+
+<https://nodejs.org/en/download/>
+

+Ensure you're still up-to-date with the latest NGINX configuration changes:

+```sh

+
+If you are using Strict-Transport-Security in your installation to continue using it you must enable it in your Nginx
+configuration as GitLab application no longer handles setting it.
+
+If you are using Apache instead of NGINX please see the updated [Apache templates].
+Also note that because Apache does not support upstreams behind Unix sockets you
+will need to let gitlab-workhorse listen on a TCP port. You can do this

+to config/initializers/smtp_settings.rb:
+
+```ruby

-// TaskList Behavior
-//
-/*= provides tasklist:enabled */
-/*= provides tasklist:disabled */
-/*= provides tasklist:change */
-/*= provides tasklist:changed */
-//
-//
-// Enables Task List update behavior.
-//
-// ### Example Markup
-//
-//   <div class="js-task-list-container">
-//     <ul class="task-list">
-//       <li class="task-list-item">
-//         <input type="checkbox" class="js-task-list-item-checkbox" disabled />
-//         text
-//       </li>
-//     </ul>
-//     <form>
-//       <textarea class="js-task-list-field">- [ ] text</textarea>
-//     </form>
-//   </div>
-//
-// ### Specification
-//
-// TaskLists MUST be contained in a `(div).js-task-list-container`.
-//
-// TaskList Items SHOULD be an a list (`UL`/`OL`) element.
-//
-// Task list items MUST match `(input).task-list-item-checkbox` and MUST be
-// `disabled` by default.
-//
-// TaskLists MUST have a `(textarea).js-task-list-field` form element whose
-// `value` attribute is the source (Markdown) to be udpated. The source MUST
-// follow the syntax guidelines.
-//
-// TaskList updates trigger `tasklist:change` events. If the change is
-// successful, `tasklist:changed` is fired. The change can be canceled.
-//
-// jQuery is required.
-//
-// ### Methods
-//
-// `.taskList('enable')` or `.taskList()`
-//
-// Enables TaskList updates for the container.
-//
-// `.taskList('disable')`
-//
-// Disables TaskList updates for the container.
-//
-//# ### Events
-//
-// `tasklist:enabled`
-//
-// Fired when the TaskList is enabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:disabled`
-//
-// Fired when the TaskList is disabled.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-container`
-//
-// `tasklist:change`
-//
-// Fired before the TaskList item change takes affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** Yes
-// * **Target** `.js-task-list-field`
-//
-// `tasklist:changed`
-//
-// Fired once the TaskList item change has taken affect.
-//
-// * **Synchronicity** Sync
-// * **Bubbles** Yes
-// * **Cancelable** No
-// * **Target** `.js-task-list-field`
-//
-// ### NOTE
-//
-// Task list checkboxes are rendered as disabled by default because rendered
-// user content is cached without regard for the viewer.
