glibc-capable Alpine

These images are almost identical to the official alpine images at the Docker hub, while being able to execute binaries that depend on glibc. This is made possible through this wonderful glibc compatibility layer. Hooks ensure that, for each build, identical copies to the current list of available tags for the official alpine are automatically (re)built.

Example

A self-contained and rather contrieved example would consist in running the docker command-line from a Ubuntu (or similar) host using this image. This works by giving away the Docker socket together with the binary from the Ubuntu host to the Alpine-based container and running the mapped binary from within the container.

docker run \
    --rm \
    -v /var/run/docker.sock:/var/run/docker.sock:ro \
    -v /usr/bin/docker:/usr/bin/docker:ro
    yanzinetworks/alpine
    docker ps

Using this technique allows to run docker from any image based on this image, much similarily to the official docker image.

Acknowledgements

The idea behind this image comes from this attempt to run grafana under an Alpine image.
