Recap # We have already seen how to enable HTTPS on a domain if you have a VPS and you are using Nginx. In one other post we have also talked about getting started with Ansible in which I wrote about basic concepts in Ansible such as inventory, module, playbook. We have also talked about Ansible Roles which are about directory structures.
Introduction # I have already posted about how we can automate installation of Jenkins & Nginx with Ansible. I have also done a post where I talk about how to enable HTTPS on a non-wildcard basis i.e. only for the root domain and not on subdomain.
Today I’ll go through how go get and configure a HTTPS certificate from Let’s Encrypt for all the subdomain. I’ll automate all these using Ansible.
