"host-access" doesn't override instructions.

Summary

When setting up a virtual machine on Azure to perform a "Join" from a node is necesary using the VM's public IP, for this razon is neceesary enable the "access-host" addon. If this is enabled using the following sequence, the assigned IP is the default one and not the last one entered.

What Should Happen Instead?

disables the DEFAULT_IP_ADDRESS ("10.0.1.1") not 20.232.Y.Z

Reproduction Steps

Step 1: I input mistake command, because I don't add IP mk8s-controlplane@mk8s-controlplane:~$ microk8s enable host-access Infer repository core for addon host-access Addon core/host-access is already enabled

Step 2: In this one add IP mk8s-controlplane@mk8s-controlplane:~$ microk8s enable host-access:ip=20.232.Y.Z Infer repository core for addon host-access Addon core/host-access is already enabled

Step 3: how to didn't work, I disabled host-access mk8s-controlplane@mk8s-controlplane:~$ microk8s disable host-access:ip=20.232.Y.Z Infer repository core for addon host-access Disabling host-access [10.0.1.1] Host-access is disabled

Step 4: then disabled all previus configuration and started agains mk8s-controlplane@mk8s-controlplane:~$ microk8s enable host-access:ip=20.232.Y.Z Infer repository core for addon host-access Setting 20.232.Y.Z as host-access Host-access is enabled

Finally work in node: user@mtb-402:~$ microk8s join 20.232.Y.Z:25000/165f852c08-- --worker WARNING: Hostpath storage is enabled and is not suitable for multi node clusters.

[sudo] password for user: Contacting cluster at 20.232.Y.Z

The node has joined the cluster and will appear in the nodes list in a few seconds.

This worker node gets automatically configured with the API server endpoints. If the API servers are behind a loadbalancer please set the '--refresh-interval' to '0s' in: /var/snap/microk8s/current/args/apiserver-proxy and replace the API server endpoints with the one provided by the loadbalancer in: /var/snap/microk8s/current/args/traefik/provider.yaml

Successfully joined the cluster.

Can you suggest a fix?

In my opinion, this is an error because it should indicate that the last IP added was the one disabled, or it should inform that there is already an IP configured and it must be disabled first before configuring a new one.

Are you interested in contributing with a fix?

yes
