Example invocation of a RabbitMQ docker container (use -d instead of -t -i to run in the background):

docker run -t -i --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management

Example of controlling the rabbitmq-server inside the container using rabbitmqctl (also inside the container).

docker exec rabbitmq rabbitmqctl status

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.
