Using this image

This is an internal base layer primarily used in docker-java.

To browse the image, run it in interactive mode with TTY enabled like so:

docker run -ti --rm ghcr.io/openzipkin/alpine:3.20.2
/ #

Release process

Build the Dockerfile using the current version from https://alpinelinux.org/downloads/:

# Note 3.20.2 not 3.19!
./build-bin/build 3.20.2

Next, verify the built image matches that version:

docker run --rm openzipkin/alpine:test -c 'cat /etc/alpine-release'
3.20.2

To release the image, push a tag matching the arg to build-bin/build (ex 3.20.2). This triggers a GitHub Actions job to push the image.
