What is Jenkins?
Jenkins is widely recognized as the most feature-rich CI available with easy configuration, continuous delivery and continuous integration support, easily test, build and stage your app, and more. It supports multiple SCM tools including CVS, Subversion and Git. It can execute Apache Ant and Apache Maven-based projects as well as arbitrary scripts.

Why use Bitnami Images?
- Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
- With Bitnami images the latest bug fixes and features are available as soon as possible.
- Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
- All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.
- Bitnami container images are released daily with the latest distribution packages available.

Prerequisites
To run this application you need Docker Engine >= 1.10.0
. Docker Compose is recommended with a version 1.6.0
or later.
How to use this image
Using Docker Compose
The recommended way to run Jenkins is using Docker Compose using the following docker-compose.yml
template:
version: '2'
services:
jenkins:
image: 'bitnami/jenkins:latest'
ports:
- '80:8080'
- '443:8443'
volumes:
- 'jenkins_data:/bitnami'
volumes:
jenkins_data:
driver: local
Launch the containers using:
$ docker-compose up -d
Using the Docker Command Line
If you want to run the application manually instead of using docker-compose
, these are the basic steps you need to run:
- Create a network
$ docker network create jenkins-tier
- Create volumes for Jenkins persistence and launch the container
$ docker volume create --name jenkins_data
$ docker run -d --name jenkins -p 80:8080 -p 443:8443 \
--net jenkins-tier \
--volume jenkins_data:/bitnami \
bitnami/jenkins:latest
Access your application at http://your-ip/
Persisting your application
If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.
For persistence you should mount a volume at the /bitnami
path. The above examples define a docker volume namely jenkins_data
. The Jenkins application state will persist as long as this volume is not removed.
To avoid inadvertent removal of this volume you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.
Mount host directories as data volumes with Docker Compose
The following docker-compose.yml
template demonstrates the use of host directories as data volumes.
version: '2'
services:
jenkins:
image: bitnami/jenkins:latest
ports:
- '80:8080'
- '443:8443'
volumes:
- /path/to/jenkins-persistence:/bitnami
Mount host directories as data volumes using the Docker command line
- Create a network (if it does not exist)
$ docker network create jenkins-tier
- Create the Jenkins the container with host volumes
$ docker run -d --name jenkins -p 80:8080 -p 443:8443 \
--net jenkins-tier \
--volume /path/to/jenkins-persistence:/bitnami \
bitnami/jenkins:latest
Customizations
For customizations, please note that this image works using the user jenkins
and uid=1001
.
Preinstalling plugins
To pass and download a set of plugins and their dependencies, use the install-plugins.sh
script. It will download them from update centers
NOTE: Default update centers must have Internet access
Plugin version format
Use plugin artifact ID, without -plugin
extension, and append the version if needed separated by :
.
Dependencies that are already included in the Jenkins war file will only be downloaded if their required version is newer than the one already included.
You can also use a custom version specifier:
latest
- download the latest version from the main update center. For Jenkins LTS images (example:git:latest
)
Script usage
You can run the script manually in the Dockerfile by adding the following after the COPY rootfs /
command:
RUN /install-plugins.sh docker-slaves github-branch-source:1.8
Furthermore, it is possible to pass a file that contains this set of plugins (with or without line breaks), you should locate this file in the rootfs
directory.
RUN /install-plugins.sh < /plugins.txt
Adding files/directories to the image
You can include files to the image automatically. All files/directories located in /usr/share/jenkins/ref
are copied to JENKINS_HOME
.
Examples:
Run groovy scripts at Jenkins start up
We can create custom groovy scripts and make Jenkins run them at start up. We can also enforce them to run at a certain order by using a prefix in the names.
However, using this feature will disable the default configuration done by the Bitnami scripts. This is intended to customize the Jenkins configuration by code.
mkdir jenkins-init.groovy.d
echo "println '--> hello world!'" >jenkins-init.groovy.d/AA_hello.groovy
echo "println '--> bye world!'" >jenkins-init.groovy.d/BA_bye.groovy
docker run -d --name jenkins -e "DISABLE_JENKINS_INITIALIZATION=yes" -v "$(pwd)/jenkins-init.groovy.d:/usr/share/jenkins/ref/init.groovy.d" -p 80:8080 -p 443:8443 bitnami/jenkins:latest
docker exec jenkins ls /opt/bitnami/jenkins/jenkins_home/init.groovy.d
AA_hello.groovy
BA_bye.groovy
docker exec jenkins cat /opt/bitnami/jenkins/logs/jenkins.log | grep world
--> hello world!
--> bye world!
Use pre-downloaded plugins
We can download plugins in a local folder and install them at run time.
docker run \
-v "$(pwd)/jenkins-plugins:/usr/share/jenkins/ref/plugins" \
bitnami/jenkins:latest \
install-plugins.sh \
role-strategy:latest
docker run -d --name jenkins \
-v "$(pwd)/jenkins-plugins:/usr/share/jenkins/ref/plugins" \
-p 80:8080 \
-p 443:8443 \
bitnami/jenkins:latest
docker exec jenkins ls /opt/bitnami/jenkins/jenkins_home/plugins/
config.xml
Run custom We can make Jenkins run our own config.xml
file.
However, using this feature will disable the default configuration done by the Bitnami scripts. This is intended to customize the Jenkins configuration by code.
In the example below we are going to use a role-based authorization strategy by default.
docker run \
-v "$(pwd)/jenkins-plugins:/usr/share/jenkins/ref/plugins" \
bitnami/jenkins:latest \
install-plugins.sh \
role-strategy:latest

NOTE: We are using a
config.xml
created by Jenkins at first run. You can consider using groovy scripts to perform this kind of configuration too.
NOTE: We are not creating the
admin
user with this setup. It should be done separately.
Passing JVM parameters
You might need to customize the JVM running Jenkins, typically to pass system properties or to tweak heap memory settings. Use the JAVA_OPTS
environment variable for this purpose:
$ docker run -d --name jenkins -p 80:8080 -p 443:8443 \
--env JAVA_OPTS=-Dhudson.footerURL=http://mycompany.com \
bitnami/jenkins:latest
Skipping Bitnami initialization
By default, when running this image, Bitnami implement some logic in order to configure it for working out of the box. This initialization consists of creating the user and password, preparing data to persist, installing some plugins, configuring permissions, creating the JENKINS_HOME
, etc.
You can skip it in two ways:
- Setting the
DISABLE_JENKINS_INITIALIZATION
environment variable toyes
. - Attaching a volume with a custom
JENKINS_HOME
that contains a functional Jenkins installation.
Upgrading Jenkins
Bitnami provides up-to-date versions of Jenkins, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the Jenkins container.
- Get the updated images:
$ docker pull bitnami/jenkins:latest
- Stop your container
- For docker-compose:
$ docker-compose stop jenkins
- For manual execution:
$ docker stop jenkins
- Take a snapshot of the application state
$ rsync -a /path/to/jenkins-persistence /path/to/jenkins-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)
You can use this snapshot to restore the application state should the upgrade fail.
- Remove the stopped container
- For docker-compose:
$ docker-compose rm -v jenkins
- For manual execution:
$ docker rm -v jenkins
- Run the new image
- For docker-compose:
$ docker-compose up jenkins
- For manual execution (mount the directories if needed):
docker run --name jenkins bitnami/jenkins:latest
Configuration
Environment variables
The Jenkins instance can be customized by specifying environment variables on the first run. The following environment values are provided to customize Jenkins:
JENKINS_USERNAME
: Jenkins admin username. Default: userJENKINS_PASSWORD
: Jenkins admin password. Default: bitnamiJENKINS_HOME
: Jenkins home directory. Default: /opt/bitnami/jenkins/jenkins_homeDISABLE_JENKINS_INITIALIZATION
: Allows to disable the initial Bitnami configuration for Jenkins. Default: noJAVA_OPTS
: Customize JVM parameters. No defaults.
