Error message “Failed to connect to the host via ssh” while running ping command on host machines through Ansible

0 votes

I have been trying to connect to machines and run a ping command on nodes using ansible. I am getting the below message.

ansible -i inventory all -m ping

Error Message:

centosinstance | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: ssh: Could not resolve hostname centosinstance: Name or service not known\r\n", 
    "unreachable": true

I have also stated the private key file and the remote user name in ansible.cfg file.

Can anyone help me with this issue ?

Just go through the error message:

Ansible can't be able to resolve the centosinstance hostname. You just need to modify your inventory as :

centosinstance ansible_ssh_host=
centosinstance1 ansible_ssh_host=
Then, change the ip addresses with the ip addresses of your machines and try it one more time. I hope this time it will work.
