launchpad apply - ssh: handshake failed

[mesmacosta]

Trying to follow the https://github.com/Mirantis/launchpad/blob/master/docs/getting-started.md.

Given I have 3 Virtual Machines:

1. xx.xx.xxx.xx4 Where I run the. launchpad
2. xx.xx.xxx.xx5 is the manager node
3. xxx.xxx.xxx.xx8 is the worker node

When running the command: ./launchpad --debug apply

This is my config file:

DEBU[0000] tracking analytics event 'Cluster Apply Started' 
DEBU[0000] opened config file from /home/my_user/cluster.yaml 
DEBU[0000] loaded configuration:
apiVersion: launchpad.mirantis.com/v1beta2

    role: worker

    engineConfig: {}
    ssh:

    installURLLinux: https://get.mirantis.com/

Then I get the error message:

Doing ssh my_user@xx.xx.xxx.xx5 ssh my_user@xxx.xxx.xxx.xx8

Work, so the ssh keys are correctly set up. Is there something I'm missing? The ssh connection opened by the GO client needs any additional config?

Was able to fix this, I disabled project level ssh access on both the worker and manager VM's.

Then I created a .pem RSA key, and used it on the ssh keyPath. Also make sure the user you are using to ssh, has passwordless sudo access on worker and manager VM's.

@mesmacosta it looks like you posted a workaround, but probably this SSH identification should be done automatically.
