Installs and configures Certbot (for Let's Encrypt).

## Requirements
If installing from source, Git is required. You can install Git using the `geerlingguy.git` role.

## Role Variables
The variable `certbot_install_from_source` controls whether to install Certbot from Git or package management. The latter is the default, so the variable defaults to `no`.
9 years ago
certbot_auto_renew: true
certbot_auto_renew_user: "{{ ansible_user }}"
certbot_auto_renew_hour: 3
certbot_auto_renew_minute: 30
By default, this role configures a cron job to run under the provided user account at the given hour and minute, every day. The defaults run `certbot renew` (or `certbot-auto renew`) via cron every day at 03:30:00 by the user you use in your Ansible playbook. It's preferred that you set a custom user/hour/minute so the renewal is during a low-traffic period and done by a non-root user account.
### Source Installation from Git
You can install Certbot from it's Git source repository if desired. This might be useful in several cases, but especially when older distributions don't have Certbot packages available (e.g. CentOS < 7, Ubuntu < 16.10 and Debian < 8).
certbot_install_from_source: no
certbot_repo: https://github.com/certbot/certbot.git
certbot_version: master
certbot_keep_updated: yes
Certbot Git repository options. To install from source, set `certbot_install_from_source` to `yes`. This clones the configured `certbot_repo`, respecting the `certbot_version` setting. If `certbot_keep_updated` is set to `yes`, the repository is updated every time this role runs.
certbot_dir: /opt/certbot
The directory inside which Certbot will be cloned.

After installation, you can create certificates using the `certbot` (or `certbot-auto`) script, which by default is installed inside the configured `certbot_dir` (when using Git). Here are some example commands to configure certificates with Certbot:
# Automatically add certs for all Apache virtualhosts (use with caution!).
/opt/certbot/certbot-auto --apache
# Generate certs, but don't modify Apache configuration (safer).
/opt/certbot/certbot-auto --apache certonly
By default, this role adds a cron job that will renew all installed certificates once per day at the hour and minute of your choosing.
You can test the auto-renewal (without actually renewing the cert) with the command:
/opt/certbot/certbot-auto renew --dry-run
