jenkins-slave-ansible

Jenkins Ansible Slave

This is a Jenkins Slave designed to run in OpenShift as described here. The slave should stay in sync with the openshift applier image in order to provide a common runtime environment.

Provides a docker image with ansible for use as a Jenkins slave.

Build local

docker build -t jenkins-slave-ansible .

Run local

For local running and experimentation run docker run -i -t jenkins-slave-ansible /bin/bash and have a play once inside the container.

Build in OpenShift

oc process -f ../../.openshift/templates/jenkins-slave-generic-template.yml \
    -p NAME=jenkins-slave-ansible \
    -p SOURCE_CONTEXT_DIR=jenkins-slaves/jenkins-slave-ansible \
    | oc create -f -

For all params see the list in the ../../.openshift/templates/jenkins-slave-generic-template.yml or run oc process --parameters -f ../../.openshift/templates/jenkins-slave-generic-template.yml.

Jenkins

Add a new Kubernetes Container template called jenkins-slave-ansible (if you've build and pushed the container image locally) and specify this as the node when running builds. If you're using the template attached; the role: jenkins-slave is attached and Jenkins should automatically discover the slave for you. Further instructions can be found here.
