Gerrit Docker image

The Gerrit code review system with PostgreSQL and OpenLDAP integration supported. This image is based on the Alpine Linux project which makes this image smaller and faster than before.

Versions

• openfrontier/gerrit:latest -> 2.13.7
• openfrontier/gerrit:2.12.x -> 2.12.7
• openfrontier/gerrit:2.11.x -> 2.11.10
• openfrontier/gerrit:2.10.x -> 2.10.6

Container Quickstart

1. Initialize and start gerrit.

docker run -d -p 8080:8080 -p 29418:29418 openfrontier/gerrit

2. Open your browser to http://:8080

Use HTTP authentication type

docker run -d -p 8080:8080 -p 29418:29418 -e AUTH_TYPE=HTTP openfrontier/gerrit

Use another container as the gerrit site storage.

1. Create a volume container.

docker run --name gerrit_volume openfrontier/gerrit echo "Gerrit volume container."

2. Initialize and start gerrit using volume created above.

docker run -d --volumes-from gerrit_volume -p 8080:8080 -p 29418:29418 openfrontier/gerrit

Use local directory as the gerrit site storage.

1. Create a site directory for the gerrit site.

mkdir ~/gerrit_volume

2. Initialize and start gerrit using the local directory created above.

docker run -d -v ~/gerrit_volume:/var/gerrit/review_site -p 8080:8080 -p 29418:29418 openfrontier/gerrit

Install plugins on start up.

When calling gerrit init --batch, it is possible to list plugins to be installed with --install-plugin=<plugin_name>. This can be done using the GERRIT_INIT_ARGS environment variable. See Gerrit Documentation for more information.

#Install download-commands plugin on start up
docker run -d -p 8080:8080 -p 29418:29418 -e GERRIT_INIT_ARGS='--install-plugin=download-commands' openfrontier/gerrit

Extend this image.

Similarly to the Postgres image, if you would like to do additional configuration mid-script, add one or more *.sh or *.nohup scripts under /docker-entrypoint-init.d. This directory is created by default. Scripts in /docker-entrypoint-init.d are run after gerrit has been initialized, but before any of the gerrit config is customized, allowing you to programmatically override environment variables in entrypoint scripts. *.nohup scripts are run into the background with nohup command.

You can also extend the image with a simple Dockerfile. The following example will add some scripts to initialize the container on start up.

FROM openfrontier/gerrit:latest

COPY gerrit-create-user.sh /docker-entrypoint-init.d/gerrit-create-user.sh
COPY gerrit-upload-ssh-key.sh /docker-entrypoint-init.d/gerrit-upload-ssh-key.sh
COPY gerrit-init.nohup /docker-entrypoint-init.d/gerrit-init.nohup
RUN chmod +x /docker-entrypoint-init.d/*.sh /docker-entrypoint-init.d/*.nohup

Setup sendemail options.

Some basic attributes in gerrit.config sendmail section are supported.

  #Start gerrit docker with sendemail supported.
  #All SMTP_* attributes are optional.
  #Sendemail function will be disabled if SMTP_SERVER is not specified.
  docker run \
  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e WEBURL=http://your.site.domain:8080 \
  -e SMTP_SERVER=smtp.server.address \
  -e SMTP_SERVER_PORT=25 \
  -e SMTP_ENCRYPTION=tls \
  -e SMTP_USER=<smtp user> \
  -e SMTP_PASS=<smtp password> \
  -e SMTP_CONNECT_TIMEOUT=10sec \
  -e SMTP_FROM=USER \
  -d openfrontier/gerrit

Setup user options

All attributes in gerrit.config user section are supported.

  #Start gerrit docker with user info provided.
  #All USER_* attributes are optional.
  docker run \
  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e WEBURL=http://your.site.domain:8080 \
  -e USER_NAME=gerrit \
  -e [email protected] \
  -d openfrontier/gerrit

  docker run \
  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e AUTH_TYPE=OAUTH \
  # Don't forget to set Gerrit FQDN for correct OAuth
  -e WEB_URL=http://my-gerrit.example.com/
  -e OAUTH_ALLOW_EDIT_FULL_NAME=true \
  -e OAUTH_ALLOW_REGISTER_NEW_EMAIL=true \
  # Google OAuth

  -e OAUTH_GITHUB_CLIENT_SECRET=secret123 \
  # GitLab OAuth
  # How to obtain secrets: https://docs.gitlab.com/ee/integration/oauth_provider.html
  -e OAUTH_GITLAB_ROOT_URL=http://my-gitlab.example.com/ \
  -e OAUTH_GITLAB_CLIENT_ID=abcdefg \
  -e OAUTH_GITLAB_CLIENT_SECRET=secret123 \
  -d openfrontier/gerrit

Using gitiles instead of gitweb

  docker run \
  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e GITWEB_TYPE=gitiles \
  -d openfrontier/gerrit

Setup DEVELOPMENT_BECOME_ANY_ACCOUNT option

DO NOT USE. Only for use in a development environment. When this is the configured authentication method a hyperlink titled "Become" appears in the top right corner of the page, taking the user to a form where they can enter the username of any existing user account, and immediately login as that account, without any authentication taking place. This form of authentication is only useful for the GWT hosted mode shell, where OpenID authentication redirects might be risky to the developer's host computer, and HTTP authentication is not possible.

  docker run \
  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e AUTH_TYPE=DEVELOPMENT_BECOME_ANY_ACCOUNT \
  -d openfrontier/gerrit

Override the default startup action

Gerrit is launched using the daemon action of its init script. This brings the server up without forking and sends error log messages to the console. An alternative is to start Gerrit using supervise which is very similar to daemon except that error log messages are persisted to ${GERRIT_SITE}/logs/error_log.

Gerrit can be started with a non-default action using the GERRIT_START_ACTION environment variable. For example, Gerrit can be started with supervise as follows:

  docker run \
      -e GERRIT_START_ACTION=supervise \
      -v ~/gerrit_volume:/var/gerrit/review_site \
      -p 8080:8080 \
      -p 29418:29418 \
      -d openfrontier/gerrit

NOTE: Not all init actions make sense for starting Gerrit in a Docker container. Specifically, invoking Gerrit with start forks the server before returning which will cause the container to exit soon after.

Sample operational scripts

An example to demonstrate the way of extending this Gerrit container to integrate with Jenkins are located in openfrontier/gerrit-docker project.

A Jenkins docker image with some sample scripts to integrate with this Gerrit image can be pulled from openfrontier/jenkins.

There's an upper project which privdes sample scripts about how to use this image and a Jenkins image to create a Gerrit-Jenkins integration environment. And there's a compose project to demonstrate how to utilize docker compose to accomplish the same thing.

Sync timezone with the host server.

docker run -d -p 8080:8080 -p 29418:29418 -v /etc/localtime:/etc/localtime:ro openfrontier/gerrit
