If you deploy an air-gapped Konvoy cluster with a very large number of nodes (> 50) then you may encounter issues with Nodes not becoming ready due to Calico failures. This happens because after 50 nodes, an additional calico deployment (calico-typha) is made to reduce the Calico traffic to Etcd. Due to an omission in the Konvoy build process, the necessary 'calico/typha' image is not provided in the air-gapped bundle.
On a machine with internet access, pull the necessary calico/typha image from the docker.io registry and push it to your local container repo. For Konvoy 1.7.x and Konvoy 1.8.x, the correct image is: calico/typha:v3.17.3
