I try to deploy Mirantis Kubernetes Engine in my VirtualBox (ubuntu).

I make a yaml file like this:

apiVersion: launchpad.mirantis.com/mke/v1.4
kind: mke
metadata:
  name: my-mke-cluster
spec:
  hosts:
  - ssh:
      address: 192.168.100.194
      user: kub
      port: 22
      keyPath: ~/.ssh/id_rsa
    role: manager
  - ssh:
      address: 192.168.100.194
      user: kub
      port: 22
      keyPath: ~/.ssh/id_rsa
    role: worker
  mke:
    version: 3.3.7
    installFlags:
      - --pod-cidr="10.0.0.0/16"
      - --admin-username=admin
      - --admin-password=admin
  mcr:
    version: 20.10.0
  cluster:
    prune: false

But I have issues to connect SSH error output is:

FATA failed on 2 hosts:

[ssh] 192.168.100.194:22: All attempts fail:
#1: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain


[ssh] 192.168.100.194:22: All attempts fail:
#1: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

The issue that you are facing is most likely connected with the SSH authorization.

As you can see in the following documentation:

  • Target machines must be configured for access via SSH using keys instead of passwords, and for passwordless use of sudo for the administrative account. This is the standard for AWS EC2 VMs.

-- Mirantis.com: Download: Mirantis cloud native platform: Mirantis kubernetes engine

I've tried to replicate the same error and it occurred when the SSH key (public one) wasn't placed in the target machine (/home/$USER/.ssh/authorized_keys or /root/.ssh/authorized_keys depending on the setup):

INFO ==> Running phase: Open Remote Connection 
INFO See /SOME/PATH/.mirantis-launchpad/cluster/hello-cluster/apply.log for more logs  
FATA failed on 2 hosts:
 - [ssh] 192.168.0.123:22: All attempts fail:
#1: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain
 - [ssh] 192.168.0.123:22: All attempts fail:
#1: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain

To fix that you would need to configure the password-less login to your target machine.

Progressing this provisioning process further should also show you the duplicate hostname error (assuming that the duplicated IP addresses are correct).
