Linux: 'Rebuild Container Without Cache' doesn't re-pull image when using 'image' in devcontainer.json

• VSCode Version: 1.70.2
• Local OS Version: Win 10 21H1
• Remote OS Version: Debian 11
• Remote Extension/Connection Type: Containers
• Logs:

Steps to Reproduce:

1. Attempt to use 'Rebuild Container Without Cache' on a devcontainer.json that uses 'image' and not 'dockerFile'

Does this issue occur when you try this locally?: Yes
Does this issue occur when you try this locally and all extensions are disabled?: Yes

Hello! I've noticed that calling 'Rebuild Container Without Cache' only works properly when the devcontainer.json is using 'dockerFile' and not 'image'. When the json file is using a Dockerfile, the container is fully rebuilt, but when it is just using 'image', no rebuild occurs and the container just restarts. Is this intentional?

It should remove the current container and create a new one. Does that not work? E.g., you can check with docker ps -a that the container id changed to verify it is a new container.

Sorry for the confusion, I confirmed it does make a new container but it does not re-pull the image the same way it does as if you are using a Dockerfile.

Attached are logs of the docker ps and
the rebuild log from inside vscode.

Any update on this? It looks like this is a regression according to #3128.
