How do docker contexts help with the transfer of image between hosts?
- dobremeno 1y agoI assume OP meant something like this, building the image on the remote host directly using a docker context (which is different from a build context) docker context create my-awesome-remote-context --docker "host=ssh://user@remote-host" docker --context my-awesome-remote-context build . -t my-image:latest This way you end up with `my-image:latest` on the remote host too. It has the advantage of not transferring the entire image but only transferring the build context. It builds the actual image on the remote host.
- revicon 1y agoThis is exactly what I do, make a context pointing to the remote host, use docker compose build / up to launch it on the remote system.
