Re: Docker Pipeline plugin: docker.withServer still executes on local Jenkins server
One year after my first post, I don't know if someone will be needing this yet, but maybe I can help someone:According to [the official installation documentation|https://jenkins.io/doc/book/installing/] today, it recommends using [jenkinsci/blueocean image|https://hub.docker.com/r/jenkinsci/blueocean/] (not [https://hub.docker.com/_/jenkins|https://hub.docker.com/_/jenkins/] as it was in the past).So, I looked for the Dockerfile (blueocean-plugin/docker/official/Dockerfile) for this image in the [jenkinsci/blueocean-plugin GitHub repository|https://github.com/jenkinsci/blueocean-plugin]. And it contains these lines:{code:java}# Add the docker binary so running Docker commands from the master works nicelyRUN apk -U add docker{code}In my tests using this new image I don't even map the "-v /var/run/docker.sock:/var/run/docker.sock". The results are: * It seems that the docker deamon is not started, so there aren't containers running inside the Jenkins container; * Now I can create pipelines in Jenkins capable of connecting to remote docker servers (or even in the local machine) using docker.withServer('tcp://my.docker.host:2345'). :)Apparently, this new image contains at least the docker client (which was not present in the old image) and it is necessary for using remote docker servers.
