Envbuilder in Coder: wrong user is used when cache is enabled

Hello, when I build image for the first time, the correct user, specified in .devcontainer is used. But when the pod is restarted and image is pulled from cache, it ALWAYS uses root user which then fails, because only the specified user has private SSH key in their .ssh which can pull from remote repository. This happens regardless of ENVBUILDER_REMOTE_REPO_BUILD_MODE set to true or false. devcontainer:

Hey @molitann can you also upload your Dockerfile? I'm able to repro this without the provider in the mix, it looks like it's related to when a user gets created as part of the devcontainer customizations I'm guessing that remoteUser should probably override whatever else gets auto-detected? try with containerUser instead of remoteUser

molitannOP•2mo ago

Oh yes that did the trick! Thank you I set both and the user is now correctly set even when the whole image is cached. Should be probably mentioned somewhere in the docs

    "remoteUser": "mmolisch",
    "containerUser": "mmolisch"

    "remoteUser": "mmolisch",
    "containerUser": "mmolisch"

Thanks @molitann ! Will add to the docs.
