Question

Not able to connect remote host via jenkins to run ansible playbook.I am able to run the playbook directly via the terminal but getting error when i do with jenkins getting below error.

fatal: [webservers]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ubuntu@<<ipaddress-masked>>: Permission denied (publickey).", "unreachable": true}
	to retry, use: --limit @/etc/ansible/ansiblecopy.retry

I have masked the ipaddress
Jenkins and ansible server are on same machine

Hey @Nishant, Can you post the output of the following command

ansible all -m ping -vvv

---

From the terminal when i excute ansible all -m ping -vvv - below is the output

webservers | SUCCESS => {
    "changed": false,
    "invocation": {
        "module_args": {
            "data": "pong"
        }
    },
    "ping": "pong"
}

When i execute from Jenkins under Build and use execute shell then also i get the success

webservers | SUCCESS => {
    "changed": false,
    "invocation": {
        "module_args": {
            "data": "pong"
        }
    },
    "ping": "pong"
}
META: ran handlers
META: ran handlers
Finished: SUCCESS

However when i execute from Anbile playbook(added ansible plugin) using plugin

TASK [Gathering Facts] *********************************************************
fatal: [webservers]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ubuntu@17x.xx.xx.xx: Permission denied (publickey).", "unreachable": true}
to retry, use: --limit @/etc/ansible/first.retry
PLAY RECAP *********************************************************************
webservers                 : ok=0    changed=0    unreachable=1    failed=0  

This will be related to some permissions issues within jenkins and i have ansible server and jenkins server on the same machine

Use SSH keys and add the Jenkins user's Private key to the Jenkins credentials store and select those in the Ansible Configuration.

Make sure you've done this!

Thanks a lot this helps can you please let me know why Jenkins credentials need to be stored and used in ansible Config i used ubuntu credentials and was trying to use those in ansible config, if you can throw some light or any link will help

---

That's how you let Ansible know that its a Jenkins build. This lets you ssh into the remote hosts as Jenkins and ansible have been configured with the required keys and credentials.

---

can you please send the detailed method to do that? and also in my case, jenkins and ansible are on different server

---

You are looking for detailed steps to add your ssh keys into jenkins server?

set "host_key_checking = False" in /etc/ansible/ansible.cfg
