Jenkins / JENKINS-50236 Add documentation on how to pass through docker configuration Issue Type: Improvement Assignee: Carlos Sanchez Components: kubernetes-plugin Created: 2018-03-17 15:49 Priority: Minor Reporter: Matt L I was using secretEnv previously to pass in credentials for my docker repository as environment vars from a K8S secret in a scripted syntax job. This was working before the most recent plugin update and I just used the ENV in a docker login script. Originally I wanted to use the image-pull-secret to just mount a config.json file at /root/.docker/config.json but that also didn't work as I think the plugin doesn't know how to mount a kubernetes.io/dockerconfigjson type. My final attempt was to pass the host volume at /root/.docker into the guest which also didn't work. I imagine others will want to pass the host docker config in since they are already using the docker.sock socket.  Add Comment

{code:java} hostPathVolume(hostPath: '/root/.docker', mountPath: '/root/.docker'){code}

Re: Add documentation on how to pass through docker configuration Looks like I misunderstood where the image-pull-secret is being stored. It appears my K8S workers do not have a /root/.docker/config.json file so it makes sense the mount doesn't work. I think it would still be good to document the recommended process for passing in docker login credentials.

Re: Add documentation on how to pass through docker configuration

There is an example using docker registry secrets with kaniko https://github.com/jenkinsci/kubernetes-plugin/blob/master/examples/kaniko.groovy if you want to open a PR on how to improve the docs...
