Gerrit Docker image

Docker Stars Docker Pulls Docker Automated build

The Gerrit code review system with external database and OpenLDAP integration. This image is based on the openjdk:jre-alpine or the openjdk:jre-slim which makes this image small and fast.

Branches and Tags

The latest is not production ready because new features will be tested on it first. The branch tags like 2.14.x or 2.15.x are used to track the releases of Gerrit. Approved new features will be merged to these branches first then included in the next release.

Alpine base

  • openfrontier/gerrit:latest -> 3.3.2
  • openfrontier/gerrit:3.2.x -> 3.2.7
  • openfrontier/gerrit:3.1.x -> 3.1.12
  • openfrontier/gerrit:3.0.x -> 3.0.15
  • openfrontier/gerrit:2.16.x -> 2.16.26
  • openfrontier/gerrit:2.15.x -> 2.15.18
  • openfrontier/gerrit:2.14.x -> 2.14.20
  • openfrontier/gerrit:2.13.x -> 2.13.14
  • openfrontier/gerrit:2.12.x -> 2.12.7
  • openfrontier/gerrit:2.11.x -> 2.11.10
  • openfrontier/gerrit:2.10.x -> 2.10.6

Debian base

  • openfrontier/gerrit:2.15.x-slim -> 2.15.18
  • openfrontier/gerrit:2.14.x-slim -> 2.14.20

Migrate from ReviewDB to NoteDB

Since Gerrit 2.16, NoteDB is required to store accounts and groups data. Changes are strongly advised to migrate to NoteDB, too. Accounts and Groups are migrated offline to NoteDB automatically during the start up of the container. Change data can be migrated to NoteDB offline via the MIGRATE_TO_NOTEDB_OFFLINE environment variable. Note that migrating changes can takes about twice as long as an offline reindex. In fact, one of the migration steps is a full reindex, so it can't possibly take less time.

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

Online migration of change data is also available via the NOTEDB_CHANGES_AUTOMIGRATE environment variable.

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

This feature is only available in Gerrit version 2.15 and above.

Container Quickstart

  1. Initialize and start gerrit.
docker run -d -p 8080:8080 -p 29418:29418 openfrontier/gerrit
  1. 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."
  1. Initialize and start gerrit using volume created above.
docker run -d --volumes-from gerrit_volume -p 8080:8080 -p 29418:29418 openfrontier/gerrit

Use a docker named volume as the gerrit site storage.

DO NOT use host volumes in particular directories under the home directory like ~/gerrit as a gerrit volume!!! Use named volume instead!!!

  1. Create a docker volume for the gerrit site.
docker volume create gerrit_volume
  1. 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

Restricting download schemes

  --name gerrit \
  -p 8080:8080 \
  -p 29418:29418 \
  -e DOWNLOAD_SCHEMES=http ssh \
  -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 how to extend this Gerrit image to integrate with Jenkins are located in the openfrontier/gerrit-ci .

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

Automatic reindex detection

The docker container automatically writes the current gerrit version into ${GERRIT_HOME}/review_site/gerrit_version in order to detect whether a full upgrade should be performed. This check can be disabled via the IGNORE_VERSIONCHECK environment variable.

Note that for major version upgrades a full reindex might be necessary. Check the gerrit upgrade notes for details. For large repositories, the full reindex can take 30min or more.

  docker run \
      -e IGNORE_VERSIONCHECK=1 \
      -v ~/gerrit_volume:/var/gerrit/review_site \
      -p 8080:8080 \
      -p 29418:29418 \
      -d openfrontier/gerrit
