Hello,
I currently try to set up XWiki on a offline machine. I read the article and installation instruction for setting up XWiki via images or docker-compose, but all I tried leads to errors in the end.
The problem is, if I just use the images, export them (on my online machine) and import them (on my offline machine) I get JAVA exceptions. I tried this with the “docker run” commands mentioned in the instructions. I think, the container tries to download some dependencies, which couldn’t be downloaded, because the machine is in a offline network. Is there a way to solve this problem here already?
Here are the exceptions:

Further things I tried is starting the container on my online system, wait till it is ready to proceed, shut it down and make an image from this container, which I will use together with the docker-compose from the instructions page. Here I get the following error:
ERROR: for db Cannot create container for service db: b’No command specified’
ERROR: Encountered errors while bringing up the project.
If I specify the command (even if I don’t know why I should, because docker-compose should run without any command) such as “\bin\bash” or “\bin\sh”, I get the error:
ERROR: for db Cannot start service db: b’OCI runtime create failed: container_linux.go:345: starting container process caused “exec: \”/bin/sh\": stat /bin/sh: No such file or directory": unkown’
ERROR: Encountered errors while bringing up the project.
I’m currently totally confused and don’t really know, why I cannot move a container from one system to another. Is there some solution here?
Best regards,
JiBREEL.
