v86/tools/docker/alpine

You can build a Alpine Linux 9p image using Docker:

1. As needed, kernel flavor (virt is smaller than lts) and set of additional packages (community repo is enabled by default) can be edited in Dockerfile
2. Check and run ./build.sh with started dockerd (podman works)
3. Run local webserver (e.g. make run) and open examples/alpine.html
4. (optional) Run ./build-state.js and add initial_state: { url: "../images/alpine-state.bin.zst" } to alpine.html
