Start Server (WebSphere) as a build step with buildah/podman to configure it

In docker I can just boot the server (WebSphere) as a build step and start configuring it via it's jython SOAP API.

I'm trying convert my Dockerfile into a shell script using buildah to create the container instead of docker build. Is there an easy way to achieve this same behaviour? (It's not working so far)

Things I tried so far:

• buildah run $container /opt/../startServer.sh server1

  result: timeout

• chroot $mountpoint bash -c "/opt/../startServer.sh server1"

  result: error: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or director

edit 1:

• Also tried running buildah build-using-dockerfile with a working Dockerfile when using docker itself but it fails with buildah.

After some searching I found out it to be a port conflict causing the server not to boot.
