 ## :bell: Changelog

- **v0.4.9**: Added a function to enrich the notify-message with release note URLs. See [Release notes addon](https://github.com/mag37/dockcheck#date-release-notes-addon-to-notifications)
- **v0.4.8**: Rewrote prune logic to not prompt with options `-a|-y` or `-n`. Auto prune with `-p`.
- **v0.4.7**: Notification Template changes to gotify(new!), DSM(improved), SMTP(deprecation alternative).
- **v0.4.6**: Compatibility changes to timeout, due to busybox.
- **v0.4.5**: Bugfixes, compatibility changes to timeout and arrays.
- **v0.4.3**: Added timeout option to skip container if registry check takes too long (10s default).
+- **v0.6.3**: Some fixes and changes:
+    - Stops when a container recreation (compose up -d) fails, also `up`s the whole stack now.
+    - `-M`, Markdown format url-releasenotes in notification (requires template rework, look at gotify!)
+    - Added [addons/DSM/README.md](./addons/DSM/README.md) added for more info Synology DSM info.
+    - Permission checks - graceful exit if no docker permissions + checking if root for pkg-manager.
+- **v0.6.2**: Style and colour changes, prometheus hotfix, new options:
+    - `-u`, Allow auto self update of dockcheck.sh
+    - `-I`, Print container release URLs in the CLI "choose update" list. (please contribute to `urls.list`)
+    - Extras: `-m`, Monochrome mode now hides the progress bar.
+- **v0.6.1**: Hotfixes: (try removing set+shopt+shopt if debugging more errors)
+    - xargs/pipefail, removed `-set -e` bash option for now.
+    - unbound variables fixed (hopefully)
+    - dependency installer from pkgmanager rewritten
+- **v0.6.0**: Refactored a lot of code, cleaner logic and syntax, safer variables.
+    - Safer bash options with `set -euo pipefail`, `shopt -s nullglob` and `failglob`.
+    - Added a `default.conf` for user settings - persistent through updates.
+    - Added `notify_slack.sh` template for slack curl api.

+## Using Dockcheck in DSM
+Dockcheck cannot directly update containers managed in the Container Manager GUI, but it can still be used to notify you of containers with updates available. There are two ways to be notified, each with their own caveats:
+
+1. Enabling email notifications within the Task Scheduler (_step 6i below_) will send an email that includes the entire script as run. This will not include the `urls.list` links to release notes, but it will show a full list of containers checked, up to date, and needing updates (following the args included in the scheduled task).
+2. The [DSM notification template](https://github.com/mag37/dockcheck/blob/main/notify_templates/notify_DSM.sh) will enable Dockcheck to directly send an email when using the `-i` flag. This is most useful when paired with an accurate [urls.list](https://github.com/mag37/dockcheck/blob/next063/notify_templates/urls.list) file, and results in a neat succinct email notification of only containers to be updated.
+
+This is a user preference, and both notifications are not necessary. However, regardless of the notification method, it is necessary to set up a scheduled task to run Dockcheck at a set interval (otherwise it will only run when manually triggered).
+
+
+## Automate Dockcheck with DSM Task Scheduler:
+
+1. Open Control Panel and navigate to Task Scheduler
+2. Create a Scheduled Task > User-defined script
+3. Task Name: Dockcheck
+4. User: root
+5. Schedule: _User Preference_
+6. Task Settings:
+    1. ✔  Send run details by email (include preferred email) _This is the optional step as described above)_
+    2. User-defined script: `export HOME=/root && cd /path/to/dockcheck && ./dockcheck.sh -n -i -I ` _or other custom args_
+8. Click OK, accept warning message
+
+
+## Set up the DSM Notification template
+
+Copy the [dockcheck/notify_templates/notify_DSM.sh](https://github.com/mag37/dockcheck/blob/main/notify_templates/notify_DSM.sh) to the same directory as where you keep `dockcheck.sh`.  
+Use as is (uses your default notification email setting) or edit and override manually.

+## [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
+# TYPE dockcheck_images_outdated gauge
+dockcheck_images_outdated 7
+# HELP dockcheck_images_latest Docker images that are outdated
+# TYPE dockcheck_images_latest gauge
