Interesting, PlatformIO doesn’t have docs for setting that up yet. Current docs. Can you file an issue in Issues · platformio/platformio-docs · GitHub for that?
If you look at the docs, every build process basically goes the same (example Github Actions):
- spin up a Ubuntu/Mac/Windows machine
- Checkout the project to compile
- Install Python (e.g., 3.9)
- Install the PlatformIO core (
pip install --upgrade platformio) - Execute
pio runin the project to compile. - (Optional: Cache PlatformIO and PIP for faster reinstall times next time)
It really doesn’t get simpler than that.
Other people have setup Docker containers that have PlatformIO preinstalled: New Docker Image.
Of course, using a rather simple Dockerfile, you could also fork from the official Python image, pip install platformio in there and be done.
I see 0 reason why one would need a graphical VSCode install in the CI. Use the PIO core standalone, that’s all you need to build stuff. (And upload. And test. And do code checks. And remote-upload and remote-test. The core has all the needed logic.)
