RabbitMQ and Erlang version Compatibility Details Needed

[Satheesh Kumar]

Hi Team,

I installed rabbitmq 3.9.23 on alpine 3.16, and now we need to upgrade to alpine 3.17, but alpine 3.17 supports erlang version 25.2, whereas rabbitmq version 3.9.23 supports minimal erlang 24.2 and maximum version is 24.3, according to rabbitmq documentation.

However, when I created a docker image with alpine 3.17, erlang 25.2, and rabbitmq 3.9.23, everything worked perfectly.

According to the rabbitmq documentation, only the rabbitmq 3.10.5 version supports Erlang 25.2.

So, is alpine 3.17, erlang 25.2, and rabbitmq 3.9.23 sufficient, or do I need to upgrade to 3.10.5 and higher?

Hello,

You should upgrade because 3.9 goes out of support in July.

Thanks,

Luke

Hi Luke,

We will undoubtedly upgrade rabbitmq in the coming months. But how does rabbitmq 3.9.23 work with an incompatible erlang version 25.2?

[Luke Bakken]

I doubt there will be issues using Erlang 25 with RabbitMQ 3.9. It's just not something we test.

Hi Luke

Will it be possible to directly upgrade from 3.9.x to 3.11.x? As a result, we have a long-term solution.
