I've created image that use for jenkins agent slave Here it is: https://hub.docker.com/r/kondaurov/jenkins_agent/~/dockerfile/
Than i run it:
docker run -d -p 2222:22 --name=jenkins_agent -v /var/run/docker.sock:/var/run/docker.sock -v kondaurov/jenkins_agent
Then i create new node in jenkins and it connects successfully via ssh
I try to run this pipeline:
pipeline {
agent {
docker {
label 'agent01'
image 'hello-world'
}
}
stages {
stage('Compile') {
steps {
sh 'whoami'
sh 'echo $PATH'
}
}
}
}
agent01 - is a container with my slave image
But it fails..

In my case, that message:
sl01978v-98210312 seems to be running inside container d93e0112b277e94c11bac40af30ddd13ef39cb312caca839497e012cd71bdf86
but /opt/jenkins/workspace/gopvolging_jenkins-somebranch could not be found among [jenkins_slave]
but /opt/jenkins/workspace/gopvolging_jenkins-somebranch@tmp could not be found among [jenkins_slave]
... was caused by the fact that the jenkins slave (which is a docker container) didn't have any volume or mount for the workspace, so the --volume-from option that Jenkins automatically passes in a DiD scenario couldn't be added. It instead tried to pass the workspace in -v, but that wasn't shared with the Jenkins slave container, so it kept waiting endlessly on the first sh command. Adding a volume for the Jenkins workspace solved it:
sl01978v-fbd455e0 seems to be running inside container 0f0090afbcece077f492be581170bf9ffb778c75e23144ccf303e9f47e9cfdd5
$ docker run -t -d -u 1000:1000 -w /opt/jenkins/workspace/gopvolging_jenkins-somebranch --volumes-from 0f0090afbcece077f492be581170bf9ffb778c75e23144ccf303e9f47e9cfdd5 ...
(the magic being --volume-from)
