VS Code web session container

[sefffal]

This session container should allow the user to launch the VS Code editor in their browser.
As it stands, they can install extensions, browse files in /arc, etc. Multiple folders can be opened simultaneously by opening the URL in multiple tabs/windows.

I imagine it could be useful to use a full editor in one tab while running e.g. notebooks in another.

This version does not come with anaconda, pluto, or any other data science software installed. I suppose that could be layered on top of this in a second image.

To make sure that it works for new users with no existing vs code config in their home folder, someone else should try building and launching this before merging.

@sefffal & @sfabbro - I have built this and published it to CANFAR. It seems to be working as far as I can tell. You can find it under the 'contributed' type and give it a try yourself. Thanks William!

Could you please provide a README.md, VERSION, and apply-version.sh file? They can be copied from ../skaha-pluto/ The version I used in CANFAR was 0.1

There are a couple issues when checking the session logs when firing a VScode session.
This is what I got:

Starting VS code session
HOME: /arc/home/sfabbro
whoami: cannot find name for user ID 20015
USER: 
fixuid: fixuid is not running as root, ensure that the following criteria are met:
        - fixuid binary is owned by root: 'chown root:root /path/to/fixuid'
        - fixuid binary has the setuid bit: 'chmod u+s /path/to/fixuid'
        - NoNewPrivileges is disabled in container security profile
        - volume containing fixuid binary does not have the 'nosuid' mount option
