Charts: what's the difference between rabbitmq and rabbitmq-ha charts?

[duyanghao]

@matejhasul @miguelaeh I am confused about the difference between rabbitmq and rabbitmq-ha charts.
Does it means that rabbitmq chart does not support high-availability?

[matejhasul]

I'm not much familiar with rabbitmq chart but at first glance there is support for HA. This chart is based on bitnami images unlike rabbitmq-ha. There are many differences for sure. I've seen PR or issue for merging these charts together but cannot find it right now :(

Hi @duyanghao ,
I am not familiar with the RabbitMQ-HA Helm Chart, but as I can read on the docs the HA for RabbitMQ is support mirroring between queues, so you only need more than one Pod that is supported by the RabbitMQ Chart.
As @matejhasul commented there are a lot of differences, but the main difference is that the RabbitMQ uses bitnami images.
But , in short, I think the RabbitMQ can be configured for HA too.
I would like to know what is the clustering method using in the RabbitMQ-HA Chart, do you know it @matejhasul ?

[duyanghao]

@migmartri @matejhasul It questioned whether it's possible to merge these two charts into one.

[miguelaeh]

I think before merge the two charts it should be evaluated the bets points of each one to combine them into a single one.
I don't know if there is a major reason why there are two RabbitMQ charts, I should be good to review older discussions about this.

The question is still not answered. I, as a starting user am very confused, and it is worth documenting the reason for having 2 different charts doing the same thing.

Can any one give us a straightforward answer about this?

[sshishov]

Very confusing. Trying to understand differences and prons/cons myself now...

even I am trying to understand the difference between these 2 charts and to add to the confusion there is one more chart on the bitnami github repo and am confused on which of these 3 has to be used to setup both HA and non HA environments
