Known Issue - Konvoy CIDR Block Migration

Background/Overview

Categories: Konvoy, Known Issues, Troubleshooting

Impacted Versions

Konvoy 1.x

Summary

By default, the following CIDRs are set during the generation of the cluster.yaml configuration: `podSubnet: 192.168.0.0/16` and `serviceSubnet: 10.0.51.0/24`. Currently, it is not possible to migrate the CIDR blocks for existing clusters as this is a Kubernetes limitation.

There is a currently open enhancement request found in the Kubernetes GitHub repository [1] to support this in the future.

Recommendation

Consider carefully planning the CIDR blocks to be used when deploying a Konvoy cluster. It is also prudent to make sure that these do not overlap or conflict with other network assets.
