Hello everyone, I have an issue I was not able to find a solution or some kind of alternative.
I want to upgrade k8s with blue/green - idea is to create new cluster on higher version (green). If everything works fine there, decomission old cluster (blue).
Although, I have mongodb and rabbitmq statefulsets so the process itself complicates.
I can use federation and shovel for rabbitmq I guess (but it is not possible to keep active-active connection with both blue and green)
On mongodb site I thought to create separate instance on green (new),assign it to mongo cluster in blue(old eks) and then make that solo instance primary (in green). However, I am not sure how the mongo will communicate in this side…
Pergaps anyone with extensive k8s knowledge could guide me a little bit or advise anything?
