[X-posting from ops-l]

Hi all,

Starting today, we are building our base container images using debuerreotype instead than bootstrap-vz, which is unmaintained [1]. This is the same tool that is used for the dockerhub debian images, and our images are now completely equivalent to the debian base images, plus our own apt configuration[2].

With this change, we're also introducing a simpler nomenclature for our base images: we will tag our images with "$codename" instead than with "wikimedia-$codename". Thus:

- the base stretch image is now docker-registry.wikimedia.org/stretch - the base buster image is now docker-registry.wikimedia.org/buster

We have also added a new image based on the (yet unreleased, caveat emptor) debian bullseye.

We will keep tagging the latest version of those images as "wikimedia-stretch" and "wikimedia-buster" for the time being, in order to allow for backwards compatibility, but we encourage everyone to migrate eventually to the new naming.

Cheers,

Giuseppe
