What would you like to be added:
Add documentation about route table quota limits with regards to overlay free networking.
Why is this needed:
In case the overlay network is disabled, the routes required by the pod network are configured in the virtual network (VPC). The aws-custom-route-controller performs this if required.
Unfortunately, the default quotas for route table entries per route table are fairly limited with only
50
entries. This means that a cluster more than50
nodes will run into the default limit resulting in a partially unusable pod network.Apart from the default limit (
50
) it is also important to mention the hard limit of1000
route table entries resulting in a hard stop regarding the amount of cluster nodes that can be used in an overlay free pod network.The text was updated successfully, but these errors were encountered:
