Check TLS certificates of sites for their expiration dates. Send notifications if configured to do so.
The script uses plugins to send out notifications. The file name of a notification plugin should be <plugin_name>_notifier.py, and should be put in the plugins/ directory.
The script looks for a certs.yaml file as its configuration in the following locations,
- current work directory, i.e.
./ ~/.check_certs/directory/etc/check_certs/directory
The configuration file has two main sections, defaults and sites.
The defaults section lists the default values of known settings to the script and its plugins. In the defaults[notifiers] section, each key should be a plugin name, which should match the prefix of the file name of the actual plugin module.
The sites section lists all the sites the script checks and their individual configurations if needed. Every default configuration can be overridden in this section.
There is an example configuration file in the examples directory.
