No such file or directory (socket: /run/docker.sock) : exception while using the library

Your Environment

The environment is the Kubernetes environment where we have jenkins slave pod which is spun up at runtime when a build job runs, this slave has a plugin which used docker-java-shaded library to tag the docker image. The docker socket /var/run/docker.sock is mounted to the pod from host machine. When the jenkins plugin running the docker-java lib is used and when it tries to tag the image, it fails with following error:

Can you please state any possible reasons for this error?

@nikita-bedmutha this project hasn't done a release in quite a while and so is many versions behind the upstream docker-java project.

With that said ... I'm not sure how you have configured the client. Did you define it to look for the docker socket at that location? If not can you try doing so and see what happens?
