All vCenter and ESXi servers require SSL encryption on all connections to enforce secure communication. You must enable SSL encryption for Ansible by installing the server’s SSL certificates on your Ansible control node or delegate node.
If the SSL certificate of your vCenter or ESXi server is not correctly installed on your Ansible control node, you will see the following warning when using Ansible VMware modules:
Unable to connect to vCenter or ESXi API at xx.xx.xx.xx on TCP/443: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:777)
To install the SSL certificate for your VMware server, and run your Ansible VMware modules in encrypted mode, please follow the instructions for the server you are running with VMware.
.certsdirectory that contains two types of files. Files with a number as the extension (.0, .1, and so on) are root certificates.
/etc/vmware/ssldirectory to Ansible control node.
