Create Jenkins Docker Image with pre configured jobs

Question

I have created a bunch of Local deployment pipeline jobs, these jobs do things like remove an existing container, build a service locally, build a docker image, run the containe

Answer 1

Jobs need to bootstrapped while the Jenkins starts can be copied to /usr/share/jenkins/ref/jobs/ folder.

But keep in mind that if the jobs(or any) already exist in Jenkins home folder, updates from /usr/share/jenkins/ref/jobs/ folder won't have any effect unless you end the files with *.override name. https://github.com/jenkinsci/docker/blob/master/jenkins-support#L110

Dockerfile

# First time building of jenkins with the preconfigured job
COPY job_name/config.xml /usr/share/jenkins/ref/jobs/job_name/config.xml

# But if jobs need to be updated, suffix the file names with '.override'.
COPY job_name/config.xml.override /usr/share/jenkins/ref/jobs/job_name/config.xml.override

Answer 2

For anyone who is interested - I found a better solution. I simply map the jobs folder to a folder on my host, that way I can put the created jobs into source control and edit then add them without having to build a new docker image.

Sorted.

Answer 3

I maintain the jobs in a bootstrap folder together with configs etc.

To add a job (i.e. seedjob) I need to add the following to the Dockerfile:

# copy seedjob
COPY bootstrap/seedjob.xml /usr/share/jenkins/ref/jobs/seedjob/config.xml
