Unable to install packages through Ansible

Question

I'm trying to install packages using Ansible but I keep getting the following error from both master and worker node

fatal: [masternode]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).", "unreachable": true}

fatal: [workernode]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).", "unreachable": true}

I'm using the following playbook

- hosts: all
  user: ansible
  become: True
  tasks:
    - name: Insall git
      yum:
        name: git
        state: present
        update_cache: True

I'm able to ping the master VM from my worker node and I'm able to ping the worker node from my master VM, so I'm not sure what the issue is.

I'm using CentOS 7 and GCP instances. I have an ansible.cfg file setup

[defaults]
inventory           = hosts
host_key_checking   = False

I also have a hosts file setup

10.128.0.3 (master node IP)
10.128.0.4 (worker node IP)

I also have the default hosts file setup (/etc/ansible/hosts)

[gcpnodes]

masternode ansible_ssh_host=10.128.0.3
workernode ansible_ssh_host=10.128.0.4

Hi,

Try to ping your all nodes. There may be a problem with connectivity, All the nodes should ping with there hostname. You can also use the below command to check.

$ ansible -m ping all
