Prevent Let's Encrypt failed authorizations with Ansible
It happens once every few years. Because of whatever reason I request another VPS at a service provider, provision the machine with Ansible and deploy a few services, usually as docker containers. And what? They don’t work, unfortunately. In 99% of the cases, I forgot to update the DNS records and with Traefik and Let’s Encrypt, I hit the rate limit while investigating and I can’t obtain any new certificate the upcoming hour. With a few lines in Ansible, this won’t happen again. Hopefully.
