We're setting a CI/CD infrastructure in order to deploy our applications on openshift/kubernetes.
We're deploying applications using jenkins, fabric8 and helm.
Nevertheless, we're creating some other kind of artifacts: init and sidecar images. So, our applications need that those images are available on kubernetes/openshift registry before main containers start.
Currently, we're building, tagging and pushing them on openshift/kubernetes registry, manually.
$ docker build .
$ docker tag image <registry>/image
$ docker push <registry>/imageWe want to automate this process, I mean, we'd really like to avoid performing these three steps and we want to avoid to configure a docker client on a jenkins slave in order to push them.
I don't know if I've explained so well.
Well you would need a seperate machine installed with docker that is used just to build and push your docker image, with a software that is triggered by jenkins to do the task. But I don't know about any software doing that.
Our solution was to install docker on a jenkins node. The build itself is written as pipeline and is commited to our scm as Jenkinsfile with the steps being:
If you dont want to use docker on jenkins and you use java something like jib could do the trick. But I'm not sure anything like that exists for other languages.
