Following up on this amazing first ticket for the topic.

RabbitMQ runs also in a cluster. Kubernetes pods are unpredictable, What should take care of while operating a RabbitMQ cluster on K8s.

  • K8s cluster updates and RabbitMQ cluster updates (losing majoring of nodes or losing quorum)
  • Pod distribution budget and other stackset configs to be aware of.
  • Simulating network partitions and needed tests to make sure the cluster is properly configured before rolling changes to a live cluster.

After a summer break from TGIR, it was nice to come back to #13 from
@omarelasfar and focus on helpful & practical advice in this new
episode. While I may not be able to tick off all the issues raised, the
list in this episode's README is more than decent.

Hi @omarelasfar,

It was a nice surprise to find this here today, thanks for taking the time. The CommitStrip is most appreciated & fitting 😄

How does the proposed list of topics in #14 look like to you?

Thanks @gerhard For looking into this proposal. It took me a while searching for the most fitting CommitStrip, more time invested in the CommitStrip than the actual ticket creation :).

Episode 06 does cover the majority of what Ifs I had in mind (Cannot see in all listed items a dedicated line item for stack sets configs /liveness and readiness probs etc). But the list is inclusive enough to provide very practical guidance on running a cluster. I think it closes this ticket and I can open a new one in case something else pops up while running a cluster.

And that's how I can tell apart those that are after quick help vs committed learning (pun intended) 🙂

Good spot! I've bumped the last item and introduced readiness & liveness probes as a first topic to tackle.

But the list is inclusive enough to provide very practical guidance on running a cluster. I think it closes this ticket and I can open a new one in case something else pops up while running a cluster.

I like your thinking 😉

I had to push this back by a few days, ETA last day in September. Have a great weekend!
