Ansible troubleshooting - VMware certificate verify failed connecting to vCenter or ESXi
Today we're going to talk about Ansible troubleshooting, specifically about the "Unable to connect to vCenter or ESXi API [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (\_ssl.c:897)" message and enable Ansible For VMware.
This fatal error message happens when the Ansible controller is not able to connect to your VMware Infrastructure. The root cause might be a self-signed SSL certificate or a chain-of-trust not correctly installed in your Ansible Controller.
I'm Luca Berton and welcome to today's episode of Ansible Pilot.
Playbook
How to reproduce, troubleshoot, and fix the error "Unable to connect to vCenter or ESXi API[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (\_ssl.c:897)".
The best way of talking about Ansible troubleshooting is to jump in a live Playbook to show you practically the "Unknown error while connecting to vCenter or ESXi API [Errno -2] Name or service not known" and how to solve it!
In this Playbook, I'm going to reproduce the error and fix using the correct VMware hostname and verify the network configuration on a demo machine.
