8 months ago Thanks for the report!
I am not able to reproduce in Codespaces (copied your repro to here if you'd like to try), or locally with the latest version of the CLI on my Mac (using Docker desktop as the engine).
One thing that stands out to me is that you appear to be using podman as the container runtime. I suspect that's what causing this behavior.
Could you please share more specific details about the container runtime and your local environment?

8 months ago Thanks @joshspicer. Indeed, I am using the podman container engine on Fedora 39. Wow, I'm not sure how I forgot to mention that crucial detail. Sorry about that.
In my setup, I have the docker socket symlinked to my user's rootless podman socket, so that the docker CLI connects to the rootless podman engine:
sudo ln --force --symbolic /run/user/$(id --user)/podman/podman.sock /var/run/docker.sock
devcontainer up --workspace-folder test1 --log-level verboseNow, if I do podman exec --latest whoami, I get root, and podman exec --latest mkdir -p /root/.devcontainer succeeds (and podman exec --latest ls /root shows the directory correctly). But if I instead do podman exec --user vscode --latest mkdir -p /root/.devcontainer, I get mkdir: cannot create directory '/root': Permission denied, which is the same error message as reported above in the devcontainer debug logs. So it seems as though devcontainer is trying to run mkdir -p /root/.devcontainer as the remoteUser user, whereas it should be running it as root. I'm not sure why docker doesn't have this problem.
This issue also occurs when running podman as root:
sudo systemctl enable --now podman.socket
sudo ln --force --symbolic /run/podman/podman.sock /var/run/docker.sock
sudo devcontainer up --workspace-folder test1 --log-level verbose

2 weeks ago To address the issue in the Podman environment where the postCreateCommand is not executed, you can use the following workaround:
Preferred Solution: Add "containerUser": "vscode" to the .devcontainer/devcontainer.json file. This ensures that all commands are run as the vscode user, preventing permission issues that occur when commands attempt to run as root.
Alternative Solution: Add user: "vscode" to the service definition in .devcontainer/compose.yaml, which is defined as the execution service in the "service" field of the .devcontainer/devcontainer.json. This also forces the container to use the vscode user.
This resolves the permission issues with Podman where the container might incorrectly attempt to run commands as root, causing failures with postCreateCommand.
