Which is the correct variable name for a document declaration that differs?

[vndroid]

          Also, you should NOT edit the kube-proxy static pod manifest; any changes you make will be reverted when RKE2 is restarted. You should use the following in your config.yaml instead:

kube-proxy-arg:
  - proxy-mode=ipvs
  - ipvs-strict-arp=true

but the document Extra Control Plane Component Environment Variables

Flag	ENV VAR
--kube-apiserver-extra-env	RKE2_KUBE_APISERVER_EXTRA_ENV
--kube-scheduler-extra-env	RKE2_KUBE_SCHEDULER_EXTRA_ENV
--kube-controller-manager-extra-env	RKE2_KUBE_CONTROLLER_MANAGER_EXTRA_ENV
--kube-proxy-extra-env	RKE2_KUBE_PROXY_EXTRA_ENV
--etcd-extra-env	RKE2_ETCD_EXTRA_ENV
--cloud-controller-manager-extra-env	RKE2_CLOUD_CONTROLLER_MANAGER_EXTRA_ENV

Why is it different?

[brandond]

Why is what different? You -arg is for adding arguments, -extra-env is for adding environment variables. They do two different things.

But the following example is not the same.

# /etc/rancher/rke2/config.yaml
kube-apiserver-extra-env:
  - "MY_FOO=FOO"
  - "MY_BAR=BAR"
kube-scheduler-extra-env: "TZ=America/Los_Angeles"

kube-apiserver-extra-env is not the ENV VAR, it is Flag.
