rabbitmqadmin v1 is being replaced with v2

[michaelklishin]

What is Changing

If you do not rely on rabbitmqadmin, a CLI tool that ships with this image,
then the changes covered below do not affect you.

This image historically has included rabbitmqadmin v1, a CLI tool that targets the RabbitMQ HTTP API.

Team RabbitMQ has developed a replacement, rabbitmqadmin v2 (doc guide, GitHub repo). The new tool has a very similar CLI but there are some differences. See the doc guide to learn about the differences and what v2 has to offer.

Why are We Doing This?

rabbitmqadmin v1 forces a Python dependency on this image. This means that the image will be
flagged for having Python CVEs very often, which has become enough of a problem for Team RabbitMQ
to develop a standalone native binary replacement that would fundamentally avoid "external" CVEs.

Using a standalone rabbitmqadmin v2 fundamentally addresses this problem.

On top of that, rabbitmqadmin v2 is developed separately, has much better test coverage, provides several significant new features, and is dramatically more efficient at rendering large responses.

The Road to rabbitmqadmin v2

The migration to rabbitmqadmin v2 has begun in #780, #787.

At first, the Alpine Linux variant of this image did not have rabbitmqadmin at all, per discussion in #780.

Now that rabbitmqadmin v2 binary builds include an Alpine-compatible statically linked MUSL variant, it can be reintroduced to the Alpine version. This was done in #787.

New builds of this image should include rabbitmqadmin v2 in both Ubuntu and Alpine variants. In the meantime, please learn about the new major version in a dedicated doc guide on rabbitmq.com.
