Remote containers in VSCodium

[Weissnix4711]

Hi,

I would like to use devcontainers in VSCodium. Is this possible?

The issues I've been facing so far seem to be that when the Remote Containers extension creates a container, it tries to install the closed source vscode server inside the container. It does this by getting the URL https://update.code.visualstudio.com/commit:e04433b713b33cd229ae8fbb747c31997b7a5074/server-linux-x64/stable where the commit hash is taken from the product.json file. The domain however does not seem to be configurable. It seems to be hard-coded into the extension.

So, obviously this VSCodium commit hash from my release isn't going to be found on Microsoft's servers. I therefore tried changing the commit option in product.json to the hash of the commit which this VSCodium build is based on. This seems to work at first, as that buid can be found on the vscode update server, and is installed in the container.

However this leads to further issues as the serverApplicationName and serverDataFolderName dir names are also taken from the product.json file. Those directories obviously don't exist in the proprietary server release which has been installed in the container. So, I changed those values as well. codium-server becomes code-server and .vscodium-server becomes.vscode-server. This probably breaks god knows what else, but never mind.

Now the container finishes building installing and running whatever tests. That's great, but the workspace is still not opened. I get an error message which says Failed to connect to the remote extension host server (Error: Connection error: Unauthorized client refused). I presume this is because of a version mismatch? I did make sure to use the commit hash which my VSCodium build is based on, but apparently this is not good enough?

Does anyone know if this can even be done, or am I wasting my time here? Is there a way to either install a different non-ms build of vscode server inside the container, or can anything be done to force code to connect to the incorrect server version regardless?

It's not possble to connect vscodium to vscode-server, vscode from MS uses a Node native addon vsda (not bundled in code-oss) which is some kind of DRM so only MS vscode desktop/server can connect which each other [1]

@Weissnix4711 You should use the assets reh which are codium-server.
And https://github.com/xaberus/vscode-remote-oss might be useful.
I will need to make times to iron out all of this...

I'd be interested too in a way to use the devcontainers extension with the open source version of Code... @github-actions please un-stale.

same for me

If I understand that correctly you'd have to do one of the following:

• adjust the devcontainer extension - to make the URL configurable; which won't work if that is a ms-licensed non-source-available extension
• create an own devcontainer extension that does the same steps than the one you refer to - which now is configurable and possibly default to vscodium
• use an existing remote extension and the devcontainer parts, possibly https://github.com/xaberus/vscode-remote-oss or https://github.com/jeanp413/open-remote-ssh

In any case there isn't anything vscodium can directly do about that (all necessary code is in, all binaries including reh are built and distributed), so I'm converting this to a discussion.

does anybody has any info / uses something that is working?

my college told me about devcontainers and it would make live easier for some of our devs in the team..

as iam the only one using vscodium (the rest uses VSC) its fine if i have to do some extra work to get it working ;-)

the goal is to setup a devcontiainer config that works for all of us ;-)

if one of you have any other good info on what is the overall thing that needs to be done please let me know..

i found xaberus/vscode-remote-oss#2
but iam not quite sure that i really understand what is done in the bigger picture to get all this working...

ok it seems i have to dig a lot deeper into all of this..

found these to tutorials and will try theme..

i have my own setup for developing thru docker containers, utilizing a different vscode ssh extension:

• https://github.com/jeanp413/open-remote-ssh

i've written about it here:

• https://blog.kipras.org/devel-core-git-macos#lightweight-linux-environment

in short, you have a docker container that runs sshd, and use the vscode extension to connect to it.

@kiprasmel Thx. Great doc!

I think it would be good if your image in the docker hub (https://hub.docker.com/r/kipras/git-dev) is linked to its source (https://github.com/kiprasmel/infra/tree/master/local/devel-core-git) and explain its relation with https://github.com/kiprasmel/voidrice 😉
