[Feature] Headless browser (chrome/chromium/firefox)

[snebjorn]

I'd love if I could add a headless browser to my dev container using the dev container features.

"features": {
  "headless-chrome": "latest",
  "headless-chromium": "latest",
  "headless-firefox": "latest",
}

All (that I know) JS/TS testing frameworks need it. Manually adding it without having to resort to --no-sandbox is very complicated. I have yet to succeed at it 😞
--no-sandbox is considered insecure and strongly discouraged.

I agree, this sounds like an awesome Feature to add!

Not exactly the same as what you're looking for, but want to point you to the existing desktop-lite Feature, that spins up a basic desktop environment that one can connect to via VNC. (https://github.com/devcontainers/features/tree/main/src/desktop-lite)

---

I'm not sure if this is something that would interest you in implementing, but we have starter code for self-authoring Features if it interested you to give it a go. We're investing a lot in making it quick/easy for members of the community to self-author (spec), and would welcome any feedback on the process.

https://github.com/devcontainers/feature-template

Useful Feature collections can then be registered via PR and will appear in our tooling for the rest of the community to enjoy (see some existing community Features at the bottom of this list 😃 https://containers.dev/features)

@joshspicer thanks for the links. I gave it a shot. But it seems there's an issue with running the tests. Not sure what is going on.

When running locally I get this error:

Also where is the docs for dev-container-features-test-lib?

[jkeech]

I'm not sure about the local test execution, but the one in the action shows the following error: https://github.com/snebjorn/devcontainer-feature/actions/runs/3193079539/jobs/5211272135#step:4:151

./install.sh: 15: Bad substitution

That maps to this line in the install script: https://github.com/snebjorn/devcontainer-feature/blob/main/src/chromium/install.sh#L15, so I think the $PATH substitution is not working properly in the script.

[snebjorn]

I copied the script from here https://github.com/devcontainers/features/blob/main/src/dotnet/install.sh#L33-L64
Does it not work or do I need to something to make it work?

[samruddhikhandale]

Hi @snebjorn, were you able to fix the test? Happy to take a look.

[snebjorn]

Hi @samruddhikhandale I don't recall what was the error when running the test on github.
But running it locally still doesn't work.
