Maybe it could be that you have to manually install some extensions. I think this does happen, so manual install is the best right now. If you want, you could use wget in your Dockerfile and manually install the VSIX files. It could be painstaking, but I think it could be easy since you will know beforehand what extensions they are and if you really need it.

If you want them to be installed on the Dockerfile itself, try code-server --install-extension=extension-filename on your Dockerfile. Use the VSIX as filename(tab autocompletion is your friend) from the Microsoft marketplace but remember, some of them might not work, like GitHub Copilot OOB, you have to do some tricks to fix it.

If this is on GitHub, I could potentially help you out with this, if you are fine.

You might think I am repeating some things, and yeah I did since I didn't read the description, I wanted to be quick. But I hope this solves it!

Hmm...So in the screenshot it sounds like the extension have been installed, I think on this last line:

CMD exec code-server /home/coder/project --host 0.0.0.0

You need to change it to:

CMD exec code-server /home/coder/project --host 0.0.0.0 --extensions-dir=/home/coder/extensions

That way code-server knows where you're installed extensions are when it starts up.
