使用Docker映像安装Jenkins插件

Question

Say we use a Docker image to run Jenkins with a container. Is there a way to install plugins in the image so we don't have to re-install if we create a new Jenkins server?

Something like:

FROM jenkins/jenkins:lts
RUN install jenkins-plugin-a
RUN install jenkins-plugin-b

etc

Answer 1

You need to create a plugins.txt file which contains list of plugins and use it in Dockerfile -

FROM jenkins/jenkins:lts
COPY plugins.txt /usr/share/jenkins/ref/plugins.txt
RUN /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt

It's there in the official documentation.

Ref - https://github.com/jenkinsci/docker (Preinstalling plugins)

Sample plugins.txt - https://github.com/jenkinsci/docker/blob/master/tests/install-plugins/pluginsfile/plugins.txt

PS - I haven't tested it yet but it's supposed to work.
