# VS Code Dev Containers

## Limitations

If you clone a Git repository using SSH and your SSH key has a passphrase, VS Code's pull and sync features may hang when running remotely. Either use an SSH key without a passphrase, clone using HTTPS, or run `git push` from the command line to work around the issue.

Local proxy settings are not reused inside the container, which can prevent extensions from working unless the appropriate proxy information is configured (for example global `HTTP_PROXY` or `HTTPS_PROXY` environment variables with the appropriate proxy information).

There is an incompatibility between OpenSSH versions on Windows when the ssh-agent runs with version <= 8.8 and the SSH client (on any platform) runs version >= 8.9. The workaround is to upgrade OpenSSH on Windows to 8.9 or later, either using winget or an installer from Win32-OpenSSH/releases. (Note that `ssh-add -l` will work correctly, but `ssh <ssh-server>` will fail with `<ssh-server>: Permission denied (publickey).` This also affects Git when using SSH to connect to the repository.)
