+### :date: Release notes addon
+There's a function to use a lookup-file to add release note URL's to the notification message.  
+Copy the notify_templates/`urls.list` file to the script directory, it will be used automatically if it's there.  
+Modify it as necessary, the names of interest in the left column needs to match your container names.  
+To also list the URL's in the CLI output (choose containers list) use the `-I` option or variable config.  
+
+The output of the notification will look something like this:
+```
+Containers on hostname with updates available:
+apprise-api  ->  https://github.com/linuxserver/docker-apprise-api/releases
+homer  ->  https://github.com/bastienwirtz/homer/releases
+nginx  ->  https://github.com/docker-library/official-images/blob/master/library/nginx

+## [Prometheus](https://github.com/prometheus/prometheus) and [node_exporter](https://github.com/prometheus/node_exporter)
+Dockcheck is capable to export metrics to prometheus via the text file collector provided by the node_exporter.
+In order to do so the -c flag has to be specified followed by the file path that is configured in the text file collector of the node_exporter.
+A simple cron job can be configured to export these metrics on a regular interval as shown in the sample below:
+
+```
+0 1 * * * /root/dockcheck.sh -n -c /var/lib/node_exporter/textfile_collector
+```
+
+The following metrics are exported to prometheus
+
+```
+# HELP dockcheck_images_analyzed Docker images that have been analyzed
+# TYPE dockcheck_images_analyzed gauge
+dockcheck_images_analyzed 22
+# HELP dockcheck_images_outdated Docker images that are outdated

mag37	29dffbb9b3	Merge pull request #92 from bocan/pre-commit-fixes style: Add pre-commit checks and code cleanup	2024-08-17 20:39:07 +02:00
Chris Funderburg	588c22afc9	style: Add pre-commit checks and code cleanup This change adds an optional pre-commit configuration that can be used to keep the code style clean. I've also run it across all files and fixed numerous whitespaces issues. To use it, if wanted, just clone / pull the repo as normal, go into the folder and run: ``` pre-commit install ``` From that point on, when running `git commit`, it will run the checks on any changed files. Feel free to ignore this PR if you're not interested.	2024-08-17 08:50:39 -04:00
