+## :tent: Install Instructions
+Download the script to a directory in **PATH**, I'd suggest using `~/.local/bin` as that's usually in **PATH**.   
+For OSX/macOS preferably use `/usr/local/bin`.
+```sh
+# basic example with curl:
+curl -L https://raw.githubusercontent.com/mag37/dockcheck/main/dockcheck.sh -o ~/.local/bin/dockcheck.sh
+chmod +x ~/.local/bin/dockcheck.sh
+
+# or oneliner with wget:
+wget -O ~/.local/bin/dockcheck.sh "https://raw.githubusercontent.com/mag37/dockcheck/main/dockcheck.sh" && chmod +x ~/.local/bin/dockcheck.sh
+
+# OSX or macOS version with curl:
+ curl -L https://raw.githubusercontent.com/mag37/dockcheck/main/dockcheck.sh -o /usr/local/bin/dockcheck.sh && chmod +x /usr/local/bin/dockcheck.sh
+```
+Then call the script anywhere with just `dockcheck.sh`.
+Add preferred `notify.sh`-template to the same directory - this will not be touched by the scripts self-update function.
+
+
+## :loudspeaker: Notifications
+Trigger with the `-i` flag.  
+Run it scheduled with `-ni` to only get notified when there's updates available!  
+
+Use a `notify_X.sh` template file from the **notify_templates** directory, copy it to `notify.sh` alongside the script, modify it to your needs! (notify.sh is added to .gitignore)  
+**Current templates:**
+- Synology [DSM](https://www.synology.com/en-global/dsm)
+- Email with [mSMTP](https://wiki.debian.org/msmtp) (or deprecated alternative [sSMTP](https://wiki.debian.org/sSMTP))
+- Apprise (with it's [multitude](https://github.com/caronc/apprise#supported-notifications) of notifications)
+  - both native [caronc/apprise](https://github.com/caronc/apprise) and the standalone [linuxserver/docker-apprise-api](https://github.com/linuxserver/docker-apprise-api)

+
+### :date: Release notes addon to Notifications
+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.  
+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
+...
+```
+The `urls.list` file is just an example and I'd gladly see that people contribute back when they add their preferred URLs to their lists.
+
+## :chart_with_upwards_trend: Prometheus and node_exporter
+Dockcheck can be used together with [Prometheus](https://github.com/prometheus/prometheus) and [node_exporter](https://github.com/prometheus/node_exporter) to export metrics via the file collector, scheduled with cron or likely.
+This is done with the `-c` option, like this:
+```
+dockcheck.sh -c /path/to/exporter/directory
+```
+
+See the [README.md](./addons/prometheus/README.md) for more detailed information on how to set it up!
+
+<sub><sup>Contributed by [tdralle](https://github.com/tdralle).</sup></sub>  
+
+## :bookmark: Labels
+Optionally add labels to compose-files. Currently these are the usable labels:
+```
+    labels:
+      mag37.dockcheck.restart-stack: true
+      mag37.dockcheck.update: true
+```
+- `mag37.dockcheck.restart-stack: true` works instead of the `-f` option, forcing stop+restart on the whole compose-stack (Caution: Will restart on every updated container within stack).
+- `mag37.dockcheck.update: true` will when used with the `-l` option only update containers with this label and skip the rest. Will still list updates as usual.
+
+## :roller_coaster: Workaround for non **amd64** / **arm64**
+`regctl` provides binaries for amd64/arm64, to use on other architecture you could try this workaround.
+Run regctl in a container wrapped in a shell script. Copied from [regclient/docs/install.md](https://github.com/regclient/regclient/blob/main/docs/install.md):
+
+```sh
+cat >regctl <<EOF
+#!/bin/sh
+opts=""
+case "\$*" in
+  "registry login"*) opts="-t";;
+esac
+docker container run \$opts -i --rm --net host \\
+  -u "\$(id -u):\$(id -g)" -e HOME -v \$HOME:\$HOME \\
+  -v /etc/docker/certs.d:/etc/docker/certs.d:ro \\
+  ghcr.io/regclient/regctl:latest "\$@"
+EOF
+chmod 755 regctl
+```
+Test it with `./regctl --help` and then either add the file to the same path as *dockcheck.sh* or in your path (eg. `~/.local/bin/regctl`).
+
+## :whale: Docker Hub pull limit :chart_with_downwards_trend: not an issue for checks but for actual pulls
+Due to recent changes in [Docker Hub usage and limits](https://docs.docker.com/docker-hub/usage/)
+>Unauthenticated users: 10 pulls/hour   
+>Authenticated users with a free account: 100 pulls/hour
+
+This is not an issue for registry checks. But if you have a large stack and pull more than 10 updates at once consider updating more often or to create a free account.
+You could use/modify the login-wrapper function in the example below to automate the login prior to running `dockcheck.sh`.
+
+### :guardsman: Function to auth with docker hub before running
+**Example** - Change names, paths, and remove cat+password flag if you rather get prompted:
+```sh
+function dchk {
+  cat ~/pwd.txt | docker login --username YourUser --password-stdin
+  ~/dockcheck.sh "$@"
+}
+```
+
+## :hammer: Known issues
+- No detailed error feedback (just skip + list what's skipped).
+- Not respecting `--profile` options when re-creating the container.
+- Not working well with containers created by **Portainer**.
+- **Watchtower** might cause issues due to retagging images when checking for updates (and thereby pulling new images).
+
+## :warning: `-r flag` disclaimer and warning
+**Wont auto-update the containers, only their images. (compose is recommended)**  
 `docker run` dont support using new images just by restarting a container.  
 Containers need to be manually stopped, removed and created again to run on the new image.

-### :hammer: Known issues
- No detailed error feedback (just skip + list what's skipped).
- Not respecting `--profile` options when re-creating the container.
- Not working well with containers created by Portainer.
+## :wrench: Debugging
+If you hit issues, you could check the output of the `extras/errorCheck.sh` script for clues.
+Another option is to run the main script with debugging in a subshell `bash -x dockcheck.sh` - if there's a particular container/image that's causing issues you can filter for just that through `bash -x dockcheck.sh nginx`.

-## `dc_brief.sh`
-Just a brief, slimmed down version of the script to only print what containers got updates, no updates or errors.

+## [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

+      - /path/to/apprise-api/config:/config
+    ports:
+      - 8000:8000
+    restart: unless-stopped
+```
+
+Then browse to the webui.
+![](apprise-ex1.png)
+Here you'll click **Configuration Manager**, read the overview and then click on **Configuration**.
+Under **Configuration** you'll craft/paste your notification config.
+
+![](apprise-ex2.png)
+The simplest way is just paste the url's as is (like in the example above).  
+There are many ways to customize with tags, groups, json and more. Read [caronc/apprise-api](https://github.com/caronc/apprise-api) for more info!  
+
+Look at the [apprise wiki: Notification Services](https://github.com/caronc/apprise/wiki) for more info about how the url syntax for different services works.  
+
+
+You can also use the [caronc/apprise-api](https://github.com/caronc/apprise-api) to host the api as a frontend to an already existing **Apprise**-setup on the host.
+
+
+### Customize the **notify.sh** file.
+After you're done with the setup of the container and tried your notifications, you can copy the `notify_apprise.sh` file to `notify.sh` and start editing it.
+
+Comment out/remove the bare metal apprise-command (starting with `apprise -vv -t...`).
+Uncomment and edit the `AppriseURL` variable and *curl* line
+It should look something like this when curling the API:
+```bash
+send_notification() {
+Updates=("$@")
+UpdToString=$( printf "%s\n" "${Updates[@]}" )
+FromHost=$(hostname)
+
+printf "\nSending Apprise notification\n"
+
+MessageTitle="$FromHost - updates available."
+# Setting the MessageBody variable here.
+read -d '\n' MessageBody << __EOF
+Containers on $FromHost with updates available:
+
+$UpdToString
+
+__EOF
+
+AppriseURL="http://IP.or.mydomain.tld:8000/notify/apprise"
+curl -X POST -F "title=$MessageTitle" -F "body=$MessageBody" -F "tags=all" $AppriseURL
+
+}
+```
+
+That's all!
+___
+___
+
+
+## On host installed **Apprise**
+Follow the official guide on [caronc/apprise](https://github.com/caronc/apprise)!
+
+### A brief, basic "get started"
+
+- Install **apprise**
+    - python package `pip install apprise`
+    - packaged in EPEL/Fedora `dnf install apprise`
+    - packaged in AUR `[yay/pikaur/paru/other] apprise`
+
+- Create a config file with your notification credentials (source of notifications):
+```ini
+mailto://user:password@yahoo.com
+slack://token_a/token_b/token_c
+kodi://example.com
+```
+Then either source the notifications with `-c=/path/to/config/apprise` or store them in *PATH* to skip referencing (`~/.apprise` or `~/.config/apprise`).
+
+- Test apprise with a single notification:
+    - `apprise -vv -t 'test title' -b 'test notification body' 'mailto://myemail:mypass@gmail.com'`
+- Set up your notification URL's and test them.
+    - Look at the [apprise wiki: Notification Services](https://github.com/caronc/apprise/wiki) for more info about how the url syntax for different services works.  
+
+### When done, customize the **notify.sh** file.
+After you're done with the setup of the container and tried your notifications, you can copy the `notify_apprise.sh` file to `notify.sh` and start editing it.
+
+Replace the url's corresponding to the services you've configured.
+```bash
+send_notification() {
+Updates=("$@")
+UpdToString=$( printf "%s\n" "${Updates[@]}" )
+FromHost=$(hostname)
+
+printf "\nSending Apprise notification\n"
+
+MessageTitle="$FromHost - updates available."
+# Setting the MessageBody variable here.
+read -d '\n' MessageBody << __EOF
+Containers on $FromHost with updates available:
+
+$UpdToString
+
+__EOF
+
+# Modify to fit your setup:
+apprise -vv -t "$MessageTitle" -b "$MessageBody" \
+   mailto://myemail:mypass@gmail.com \
+   mastodons://{token}@{host} \
+   pbul://o.gn5kj6nfhv736I7jC3cj3QLRiyhgl98b \
+   tgram://{bot_token}/{chat_id}/
+
+}
+```
+
+That's all!

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.
