Hi trying to understand the HA installation with 23 R1, when we did a few test installations it seems that the number of containers on every node was varied, i hade expected the number of containers to be the same, then i realized that in the yaml file the number of replicas was set to 1.

Is it the case that this would lead to a unbalanced distribution of the containers on the 3 nodes, and would i be right in assuming that for a HA design with 3 nodes and a hardware load balancer the number  of replicas required to achieve full HA would be 3.

 

And is there any more detailed documentation for the HA solution that someone can point me too ?

This is the way how it works. If you have replicas set to 1, HA will run the 1 pod on node 1 or 2 or 3, you cannot control that. In case of damage of the node where the pod is running, the cluster will move the pod on the next node. If you set replicas to 3 for example, the pods will be distributed across the nodes, the decision which pod runs on which node is taken by the cluster.
