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

Thank you for reporting your issue, @mevgdev. It seems like there might be a conflict with the host-access addon due to enabling it twice with different IP addresses. Based on your description, it appears that you may not need the host-access addon for your current task.
Please provide us with specific details on what needs fixing. If further assistance is needed, feel free to reach out. We are here to help you.
