From 9338c6325263d950966e87ddb23095075f18558e Mon Sep 17 00:00:00 2001 From: kfei Date: Wed, 17 Dec 2014 00:53:17 -0800 Subject: Gracefully shutdown services in Docker container The problem is `docker stop` only sends SIGTERM to the PID 1 inside the container, and the PID 1 (`/bin/sh -c ...`) does not take care of signals. Hence the services (e.g., postgresql, redis, sidekiq, etc) never have chances to graceful shutdown. Docker just kills the container after its 10 seconds timeout by default. What this commit does: 1) Add a wrapper as the default executable of Docker container. Which starts services through `runit`, reconfigure Gitlab by `gitlab-ctl` and gracefully shutdown all services when a SIGTERM is received. 2) Create an `assets` directory for assets. 3) Add `.dockerignore` file. Now you'll see the following log messages after `docker stop`: ``` SIGTERM signal received, try to gracefully shutdown all services... ok: down: logrotate: 1s, normally up ok: down: nginx: 0s, normally up ok: down: postgresql: 1s, normally up ok: down: redis: 0s, normally up ok: down: sidekiq: 0s, normally up ok: down: unicorn: 0s, normally up ``` Signed-off-by: kfei --- docker/gitlab.rb | 37 ------------------------------------- 1 file changed, 37 deletions(-) delete mode 100644 docker/gitlab.rb (limited to 'docker/gitlab.rb') diff --git a/docker/gitlab.rb b/docker/gitlab.rb deleted file mode 100644 index 7fddf309c01..00000000000 --- a/docker/gitlab.rb +++ /dev/null @@ -1,37 +0,0 @@ -# External URL should be your Docker instance. -# By default, this example is the "standard" boot2docker IP. -# Always use port 80 here to force the internal nginx to bind port 80, -# even if you intend to use another port in Docker. -external_url "http://192.168.59.103/" - -# Prevent Postgres from trying to allocate 25% of total memory -postgresql['shared_buffers'] = '1MB' - -# Configure GitLab to redirect PostgreSQL logs to the data volume -postgresql['log_directory'] = '/var/log/gitlab/postgresql' - -# Some configuration of GitLab -# You can find more at https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#configuration -gitlab_rails['gitlab_email_from'] = 'gitlab@example.com' -gitlab_rails['gitlab_support_email'] = 'support@example.com' -gitlab_rails['time_zone'] = 'Europe/Paris' - -# SMTP settings -# You must use an external server, the Docker container does not install an SMTP server -gitlab_rails['smtp_enable'] = true -gitlab_rails['smtp_address'] = "smtp.example.com" -gitlab_rails['smtp_port'] = 587 -gitlab_rails['smtp_user_name'] = "user" -gitlab_rails['smtp_password'] = "password" -gitlab_rails['smtp_domain'] = "example.com" -gitlab_rails['smtp_authentication'] = "plain" -gitlab_rails['smtp_enable_starttls_auto'] = true - -# Enable LDAP authentication -# gitlab_rails['ldap_enabled'] = true -# gitlab_rails['ldap_host'] = 'ldap.example.com' -# gitlab_rails['ldap_port'] = 389 -# gitlab_rails['ldap_method'] = 'plain' # 'ssl' or 'plain' -# gitlab_rails['ldap_allow_username_or_email_login'] = false -# gitlab_rails['ldap_uid'] = 'uid' -# gitlab_rails['ldap_base'] = 'ou=users,dc=example,dc=com' -- cgit v1.2.1
