A Docker config for makecode.adafruit.com for Circuit Playground Express
This is a locally-hosted version of the makecode web programming tool for the Circuit Playground Express.
In theory, I will be able to conduct a CPX workshop in a location with no internet, by running this docker container from my laptop and having participants browse to http://MYIPADDRESS:3232
Download Docker Desktop. If you're using Windows, I'd suggest following these instructions for making Docker Desktop work with WSL2.
The Docker image is DockerHub. You can pull it from there to your computer with this command:
docker pull robduarte/makecode-cpxRun the container like this: docker run -p 3232:3232 -p 3233:3233 robduarte/makecode-cpx
It will take a few minutes for the server to start. Once the server has been successfully started, part of the process appears to start again, which I haven't figured out. Because of this, you will need to scroll up a bit to find the URL in the text being logged to the console. The URL has a hostname of 0.0.0.0 but you'll need to change that to something else as described below.
To access the MakeCode website from the same machine that is running the Docker container, you'll need to change the 0.0.0.0 part of the URL to the "localhost" address of 127.0.0.1
I'm planning to use this to give workshop participants access to the MakeCode web-based tool even though there will be no Internet access at the workshop location. I will bring a wifi router that I have hanging around and ask everyone to connect to that router. Although they won't have Internet access, their computer should be able to contact my laptop (which is running the Docker container). In this case, I will give participants the URL from above, but I will replace 0.0.0.0 with my accessible WiFi IP address.
