Executing this from mac

./install/ansible/install_swarm.sh -f install/ansible/cfg.yml -e ~/.ssh/ssh-key -u admin -i
Starting the installer container
Generating Ansible configuration

WARNING Some of the hosts are not accessible via passwordless SSH

This means either the host is unreachable or passwordless SSH is not
set up for it. Please resolve this before proceeding.

The same host is accessible via ssh from the host:

ssh admin@15.29.37.216 -i ~/.ssh/ssh-key

@DivyaVavili This is internal setup issue and not related to installer. Could you please try on your linux machine, rather than trying from mac. You need to add static IP route to private lab network.

Hi @DivyaVavili,

I had the same problem and for me the problem was the following:

For some strange reasons Ansible requires an ECDSA private key (RSA is not working).

  1. Therefore generate a ECDSA key using ssh-keygen -t ECDSA.
  2. sudo ssh-copy-id -i ~/.ssh/contiv_id_ecdsa.pub admin@192.168.X.X
  3. ./install/ansible/install_swarm.sh -f install/ansible/cfg.yml -e ~/.ssh/contiv_id_ecdsa -u admin

Regards, Philip
