如何在脚本化的 Jenkinsfile 管道中构建和运行 Docker 映像？

Question

I'm trying to build and run a docker image on a specific build node from a scripted Jenkinsfile. Switching to declarative syntax is something I would rather like to avoid. My code is quite close to the example from the documentation . The image builds as expected. But running the container fails Jenkins complaining the physical machine of the node is not running inside a container and the echo and make commands from the innermost block that I would expect to run inside the container are not executed and do not appear in the log.

As far as I understand Jenkins considers containers to be build nodes on their own and that nesting of node statements are not allowed. At the same time a node is required to build and run the Docker image.

What am I missing to build and run the image? As Im quite new to Jenkins as well as to Docker any hints or recommendations are appreciated.

The code:

node('BuildMachine1')
{
    withEnv(envList)
    {
        dir("/some/path")
        {
            docker.build("build-image:${env.BUILD_ID}", "-f ${env.WORKSPACE}/build/Dockerfile .").inside
            {
                echo "Echo from Docker"
                sh script: 'make'
            }
        }
    }
}

The log:

Looks like the Entrypoint of the container was configured in a way that worked for manual usage in terminal but not inside the Jenkins pipeline. It was set as ENTRYPOINT ["/usr/bin/env", "bash"] After changing it to ENTRYPOINT [ "/bin/bash", "-l", "-c" ] the resulting container is used by the Jenkinsfile as intended.
