Hi, would you mind running the de[ployment like this?

ansible-playbook     -v --user root     -e kubeinit_spec=k8s-libvirt-1-1-1   -e hypervisor_hosts_spec='[[ansible_host=nyctea],[ansible_host=tyto]]'      ./kubeinit/playbook.yml

I bet you are using the default inventory file, there might be a nit there.

[Gl1TcH_1n_Th3_M4tR1x]

Or you can have:

hypervisor_hosts:
  hosts:
    hypervisor-01:
      ansible_host: nyctea
    hypervisor-02:
      ansible_host: tyto

In your inventory.yml file

[Jeff Bailey]

@ccamacho I updated to the latest code and ran the command.

I encountered a new error.

fatal: [hypervisor-01]: UNREACHABLE! => {"changed": false, "msg": "Data could not be sent to remote host \"nyctea\". Make sure this host can be reached over ssh: Warning: Identity file /root/.ssh/kubeinit_id_rsa not accessible: Permission denied.\nCan't open user config file /root/.ssh/k8scluster_config: Permission denied\r\n", "unreachable": true}

I wonder if it makes sense for me to clone this repo and set up a test like this one for Rocky Linux & Raspian?

https://github.com/Kubeinit/kubeinit/actions/workflows/distro_test.yml

What do you think?

@Gl1TcH-1n-Th3-M4tR1x Thanks for the input, but the inventory.yml already contains that configuration.

Thanks for the input, but the inventory.yml already contains that configuration.

NO. IT DOES NOT.

The inventory file contains commented out lines like this:

We calculate the inventory dynamically so we dont expect you to have anything there.

# -e hypervisor_hosts_spec='[{"host":"hypervisor-01","ansible_host":"192.168.222.202"}]'

ie ansible extravars format, not even yaml.

The proper inventory file stuff suggested by @Gl1TcH-1n-Th3-M4tR1x is NOT THERE.
So it sounds like it has been accidentally deleted for some reason, and it should either be re-instated, or the instructions amended, because this bug is now 6 months old, and I have hit this same issue.

[Carlos Camacho Gonzalez]

I didnt see this again @jeffabailey I built all the packages for aarch64 but there are some changes needed in the guest vm images to have it running in ARM. (Rocky should work ootb I dont think this will ever work on a raspberry)

[John]

Ok, if inventory is calculated dynamically, and you dont expect anyone to use it, then why do instructions say:

Adjust the inventory file to suit your needs.
By default the first hypervisor node is called nyctea (defined in the inventory). Replace it with the hostname you specified if you changed it. You can also use the names in the inventory as aliases for your own hostnames using 

It is no wonder people are struggling with this, when the instructions are misleading.

Further, the contents of the inventory file give this as an example of setting the ansible extravars:

# -e hypervisor_hosts_spec='[{"host":"hypervisor-01","ansible_host":"nyctea","ssh_hostname":"server1.example.com"}]'

But ccamacho on Jun 27 suggested Jeff use:

#-e hypervisor_hosts_spec='[[ansible_host=nyctea],[ansible_host=tyto]]'

That's a completely different format for the var. So what is going on with that?

It would be helpful to clarify the syntax for this extra var - both, in the inventory file, and, in the main instructions!
