Q: Can I connect multiple VS Code windows to a single container?

Yes! With your two windows open do the following on each:

1. Connect both VS Code windows to the same host.
2. Using one of the windows, open your project.
3. Once your project is open, either build the container or reopen in the container.
4. (Optional) To verify the current container name, type docker ps.
5. Using your 2nd window, press the remote connections button (bottom left corner).
6. Select the option “Attach to Running Container…” and follow through the dialogues to select the container running in the other window (if necessary, check step 4.).

You now have 2 VS Code windows connected to the same container!

For more details, refer to this step in the container management tutorial.

Q: How do I run a long running job in the background on a server?

This is assuming that you are using a dev container or an operating system with tmux installed. Here are quick start steps:

1. In your terminal, type and run tmux.
2. Now run your long running job.
3. Run tmux detach to detach from the tmux session.
4. Feel free to disconnect from the server (but leave your devcontainer running!)
5. Reconnect to the server and reattach to the devcontainer.
6. Run tmux attach
7. Your job will either be there running or completed!

For more details, refer to this step in the job management tutorial.
