Move Docker image to ubuntu core

Hello, I booted Ubuntu Core on a machine and I accessed it via ssh. Afterwards, I installed the Docker snap and now I am trying to load a Docker image from a tar archive. However, I don’t really now how to do this.

How can I move my 12 Gb image to the Ubuntu Core filesystem, so as to be able to run the docker load command? Can I create a custom Ubuntu Core image with the tar archive already inside the file system? If the answer is yes, how can I do that?

Thank you in advance

  1. I think SCP should do the trick.
  2. Yes, it’s possible to do so using custom gadget snap. Here you can include docker snap and more. Also those two articles might be helpful to integrate more between docker and snaps: Run a Docker container | Ubuntu In your case, I think custom docker-based snap might be the solution.
