Sandbox in a form of Docker container

[p1-afv]

What variant of Codex are you using?

App / CLI

What feature would you like to see?

Considering that Codex application is purely a local desktop app and normally works only with locally installed repositories.
In some cases these repositories are to be running on a different platform, like Linux or something like that, then it's almost impossible to utilize all the codex capabilities to perform testing and run some scripts, whatever. Would it be possible to have a sandbox, or as it's called, some Worktree from the repository is created in the specific container with the given configuration, say what kind of operating system should be running there, what kind of packages have to be installed there, etc., and then probably all the code changes could be done locally, while the same code can be attached as a volume to the Docker container in order to perform testing.

Alternatively, it could be fully blown remote development similar to VS Code does via SSH. Why don't we have Codex CLI running as, for example, MCP or just its limited server version a remote host? And then the Codex application has access to that remote host via SSH and collaborates with the host‑deployed Codex server for coding.
