Closed rancherbot closed 1 year ago

rancherbot commented 1 year ago

This is a backport issue for https://github.com/rancher/rke2/issues/4580, automatically created via rancherbot by @manuelbuil

Original issue description:

Describe the solution you'd like

Currently, calico-node or felix do not check on OS level env variables when executing their processes, something that makes it hard to change the default config

Describe alternatives you've considered
