I have a Kubernetes cluster (installed on premise), and I deployed an application based on Websphere Liberty image (from docker hub).
I configured a session affinity (or sticky session) for my service, then it can keep session via requests (access the same pod). But now, I want to keep application session when a node or pod died (for HA and using LB). Can I do that in Websphere liberty ? How to setup a Websphere liberty cluster
You can configure session persistence via hazelcast or via a traditional database running inside or outside of the cluster. This frees the application from being sensitive to scaling up/down.
