Gitpod: Gitpod doesn't work well with jekyll

[Kreyren]

Describe the bug

Using JEKYLL_ENV=development bundle exec jekyll serve to provide a theia preview of the website causes 404, because gitpod is using localhost:4000 that is not accesible to gitpod user.

This can either be workedaround using:

• Firefox in noVNC
• Rewriting the whole repository to accept special gitpod environment
• Weird hack alike cat _config.yml | sed -E "s#^(url:\s{1})(\").*(\").*#\1\2$(gp url)\3#gm" > _config_gitpod.yml && JEKYLL_ENV=production bundle exec jekyll serve --config _config_gitpod.yml which is not acceptable for gitpod users.

Expected behavior

We need some way to display localhost:4000 in theia's preview, maybe some wrapper for theia's preview that points to $(gp url) everytime localhost is called on it?

This is a problem on Jekyll's end for forcibly using localhost instead of the dynamic public address

[Kreyren]

@RDIL Possible i guess, what do you propose then?

Maybe you’ve already tried this, but Jekyll accepts a bind param eg

jekyll serve —host=0.0.0.0

That should listen on all interfaces.

[Kreyren]

@qnm Already tried.. The host can only point to localhost it seems even when i parsed an IPv4 of the workspace to it.

I don't see how this could be solved in the frontend. As long as the preview is running as an iframe (webview), we would need to intercept the requests to localhost which is not possible.
Therefore running a browser in the remote container and somehow showing the rendered ui in the browser seems to be the only generic solution. There is https://github.com/auchenberg/vscode-browser-preview based on chrome headless but also your VNC proposal seems similar.

FWIW I think patching the config in a gitpod config is not too bad either, but for instance the livereload would not work that way.

Trying the extension which on gitpod results in

trying to install chrome..

and even with that it doesn't work, because theia wants to use it's preview at all cost

Checking if vnc helps~

UPDATE: Seems that i've provided dependencies for the browser preview which now results in:
