Problem to execute microk8s CLI MacOs BigSur 11.4

[olympien13]

I have a Mac with BigSur v11.4 installed I followed the instructions to install MicroK8s on top of it.
https://microk8s.io/docs/install-alternatives#heading--macos

The installation went successfully without any errors.
"microk8s install" installed perfectly too and I run it again I got that output:
microk8s install
MicroK8s is up and running. See the available commands with microk8s --help

However I can not execute any of others CLI commands"microk8s" commands such as "status", "stop",
microk8s status
sudo: microk8s.status: command not found
An error occurred when trying to execute 'sudo microk8s.status' with 'multipass': returned exit code 1.

microk8s stop
sudo: microk8s.stop: command not found
An error occurred when trying to execute 'sudo microk8s.stop' with 'multipass': returned exit code 1.

Any Clue ? Any idea ? Any suggestions that could help me ?

On MacOs K8s runs in a VM that is driven by Multipass [1]. Could you check if Multipass is ok and that there is a MicroK8s VM running?

Hi,

Multipass is also installed successfull and the VM is running fine as you can see:
multipass list
Name State IPv4 Image
microk8s-vm Running 192.168.64.9 Ubuntu 18.04 LTS

If you get into the VM with multipass shell microk8s-vm do the microk8s commands work? For example how does your microk8s status and microk8s kubectl get all -A look like? If they do not can you fetch a microk8s.inspect tarball (with the help of multipass transfer) and attach it to this issue?

[olympien13]

Hi,
Here are the output of the two commands you asked me to enter into the multipass VM:
ubuntu@microk8s-vm:/$ microk8s status
microk8s: command not found
ubuntu@microk8s-vm:/$ microk8s kubectl get all -A
microk8s: command not found

Indeed as if it was not installed into the VM.

Regarding the microk8s.inspect how I can invoke it ?
Here is the output the "microk8s inspect" on my mac:
microk8s inspect
sudo: microk8s.inspect: command not found
An error occurred when trying to execute 'sudo microk8s.inspect' with 'multipass': returned exit code 1.

Into the VM here is the output:
ubuntu@microk8s-vm:~$ microk8s inspect
microk8s: command not found

Could it be /snap is not in the PATH? How does ls /snap and snap list look like? It is strange that the VM got created but the snap is not installed. @joedborg have you seen this before?

[olympien13]

I was able to find out indeed that I had to execute manually the command into Multipass VM:
sudo snap install microk8s --classic --channel=1.18/stable

in order to make it work.

Not sure this is normal I had to run it manually as it is not clearly stated according to me in the doc :
https://microk8s.io/docs/install-alternatives#heading--macos

I still have a small issue. Indeed while executing the "microk8s kubectl" CLI commands into the Multipass VM it works fine. However when trying to invoke them from my Mac, I got:

microk8s kubectl get pods --all-namespaces
error: stat /Users/Livigni/.microk8s/config: no such file or directory

microk8s kubectl get nodes
error: stat /Users/Livigni/.microk8s/config: no such file or directory

I guess one configuration step is also missing but don't know which ?

[ktsakalozos]

You can get the kubeconfig file by running microk8s config.

[olympien13]

Great. I had to create by hand the directory ".microk8s" and the content of the microk8s config command within a file named config.
Works now from my Mac as expected.
@ktsakalozos Thanks a lot for your help and support

I just installed microk8s on my mbp

 % sw_vers
ProductName:	macOS
ProductVersion:	12.3.1
BuildVersion:	21E258

And still see that the directory ~/.microk8s was not created automatically? The workaround above worked for me too.

1. Manually create the directory ( mkdir ~/.microk8s )
2. Grab the config from the VM environment directly ( multipass shell microk8s-vm, microk8s config )
3. create a file ~/.microk8s/config with the contents from point (2)

Same issue for me as well in my Macbook.Post this snap installation getting microk8s working.

After Mac upgrade (Mac Monteray, 12.6.1), I got following error:
microk8s start

start failed: The following errors occurred:
Instance stopped while starting
An error occurred when trying to execute 'sudo microk8s.start' with 'multipass': returned exit code 2.

Somehow my VM failed to start and was stuck, executed multipass list to find the status of VM:
multipass list

Name State IPv4 Image
microk8s-vm Starting -- Ubuntu 18.04 LTS

I then executed following command to recover:

multipass stop microk8s-vm
multipass delete microk8s-vm
multipass purge

and then finally reinstalled microk8s:
microk8s install

This finally fixed the issue.
