How to create ansible master on GCP VM instance?

Question

I tried to create ansible master on instance-1 in GCP. And I have an application instance-2. When I try to connect from instance-1 to instance-2 I always get error message - Permission denied (publickey).

I added instance-2 ssh public key to authorized_keys and configured parameter PasswordAuthentication to yes in sshd_config. In ansible file I have this:

 sba ansible_host=35.**.57.** ansible_user=admin 
 ansible_ssh_private_key_file=/home/admin/.ssh/app_gcp

Also I can't do sudo ssh-copy-id 35.111.57.111

Answer 1

The problem was in wrong ansible_ssh_private_key_file. It should point on the id_rsa of the current machine.
