Thanks Jason. OK. let me in detail out all steps which i carried out. Created Dockerfile (PFA). Created Jenkins Job which will is connected to one UNIX box (using ssh port : 22) on which docker daemon is running
as a part of Jenkins job configuration, i choose the option "Build inside a Docker container" when i started the build , job builds the Dockerfile and image gets created successfully. further, job runs that image in container and now that image is ready for use. After that, when i am simply running command "java -version" as a part of build step and that step is failing because it is not finding that version of java which i set as a part of dockerfile. As per your comment (if i understand correctly), i am not starting container, job itself builds the image from Dockerfile and start the container. further, i don't know how to ssh to running container from the Jenkins job itself. is there already option in Jenkins job ? I have seen option "Start/Stop container " as a build step .. but not getting feel of how to use it Please suggest Regards On Sun, Nov 1, 2015 at 10:37 PM, Jason Swager <[email protected]> wrote: > If you're using the Docker plugin ( > https://wiki.jenkins-ci.org/display/JENKINS/Docker+Plugin), I found the > env vars worked fine when they were setup to be available to incoming .ssh > connections.
