There are 3 ways I know of that allows you to avoid having the Jenkins
slave dependency in the container:
1. Use Docker Slaves Plugin
- Has some limitations, but works for the most part. Supports
pipeline at least partially, and can run on dockerized slaves. Will not
run directly on existing slaves but will provision on the fly from
docker. Only supports one docker host and a single global limit on
number of containers.
2. Use Cloudbees Docker Custom build environment plugin
- A bit old codebase, that does not support newer docker features.
Does not support running as a sibling container to a jenkins slave
container. No pipeline support. Uses existing slaves that must have
docker support, so multiple docker hosts are possible. Someone requested
to adopt this plugin some time ago, so this can change over time.
3. Use the Docker Pipeline plugin, specifically the .inside syntax
- This only supports pipeline, nothing else. Very mature and is the
new way to do this. Uses existing slaves that must have docker support,
so multiple docker hosts are possible. Supports running as a sibling
container to a Jenkins slave container (with docker socket bind mounted).
All 3 have the property that you can use any oracle linux image that you
have without worrying about installing the correct JRE version for
Jenkins. The actual Jenkins node can be any slave with Docker running.
Note that this has the added bonus that a new container is created for
every build, so anything your builds can do to your build environment
will not affect future builds.
IMO, your best bet is option 3 if you can, i.e. you have everything
running in pipeline.

Hi ,
We have a problem on Jenkins on which container the job will run.
By default jenkins job is using jnlp container to run the Jobs.
inorder to run the jobs on the oraclelinux image.
1. We Successfully created docker-jnlp-slave image with oraclelinux image.
2. Able to pull docker-jnlp-slave image and create container.
3. Jnlp and docker-jnlp-slave(oraclelinux ) 2 containers created.
Test job console output shows that , By default jenkins job is using
jnlp container (jenkins/jnlp-slave:alpine)
is there a way to run jobs on oraclelinux container.

Basanta
