These init containers copy the appropriate redis configuration by analysing the hostname of the pod. The data is automatically split among multiple nodes, which allows operations to continue, even when a subset of the nodes are experiencing failures or are unable to communicate with the rest of the cluster. We see that the IP for redis-cluster-0 has changed, so how did the cluster heal? Our application containers are designed to work well together, are extensively documented, and like our other application formats, our containers are continuously updated when new versions are made available.
