Finch could not be used as a docker replacement for Dev Containers in VSCode

[normalerweise]

Describe the bug
Briefly describe the problem you are having.

Steps to reproduce
Follow: https://code.visualstudio.com/docs/devcontainers/tutorial
However after installing Dev Containers extension, go to the extensions settings and replace Docker and Docker Compose Path settings with the corresponding finch path (see screenshot)

Expected behavior
Visual Studio Code Dev Containers successfully starts a dev container using finch

Screenshots or logs

Additional context
Finch seems to not support the --format parameter for the version command

To help debug the issue as quickly as possible, we recommend generating a support bundle with finch support-bundle-generate and attaching it to this issue. This packages all Finch-related configs and logs into one file.

The issue to track --format. #199

[weikequ]

Was able to do a patch to get past the version --format check, but getting some subsequent errors. Anyone have any idea?

Looks like it wants to use temp folders in /var/folders/nn...; I assume that path is not mounted in the VM?

[weikequ]

Since #525 is merged for better compatibility, we are unblocked for this previous issue. But upon further investigation, it seems like we may have hit a wall with it looking to mount the docker socket file to proceed.

If I supply it a dummy docker.sock file, it proceeds to predictably fail a few lines later running a docker command.
