Possibly a duplicate of JENKINS-46831.  The title reads one way and the comments read other ways to me.

Problem

Caused: java.io.IOException: Cannot run program "docker" (in directory "/home/jenkins/agent/workspace/test"): error=2, No such file or directory

My impression is that Jenkins is trying to run Docker in the labeled agent due to the pipeline-level Docker agent configuration despite specifying an agent by label for the last stage. Aside from whether this is a unique bug, I am certainly open to suggestions about a better structure for this. Note that in the real case there are many stages that I want run with the pipeline-level specified Docker agent.

Setup

• Download the attached files. Run the following `docker-compose` to bring up Jenkins.
  • docker-compose build --build-arg DOCKER_SOCK_GID=$(stat -c '%g' /var/run/docker.sock) && docker-compose up --renew-anon-volumes --remove-orphans

• Open http://localhost:8080/
• Enter password from Jenkins startup

  • Select None
  • Select Install
• Skip and continue as admin
• Save and finish
• Start using Jenkins
• New Item
