+```
-```shell
 $ ./dockcheck.sh -h
-Syntax:     dockcheck.sh [OPTION] [comma separated names to include]
+Syntax:     dockcheck.sh [OPTION] [part of name to filter]
-Example:    dockcheck.sh -y -x 10 -d 10 -e nextcloud,heimdall
+Example:    dockcheck.sh -a ng
 
 Options:
--a|y   Automatic updates, without interaction.
--b N   Enable image backups and sets number of days to keep from pruning.
--B     List currently backed up images, then exit.
--c D   Exports metrics as prom file for the prometheus node_exporter. Provide the collector textfile directory.
--d N   Only update to new images that are N+ days old. Lists too recent with +prefix and age. 2xSlower.
--e X   Exclude containers, separated by comma.
--f     Force stop+start stack after update. Caution: restarts once for every updated container within stack.
--F     Only compose up the specific container, not the whole compose stack (useful for master-compose structure).
 -h     Print this Help.
--i     Inform - send a preconfigured notification.
+-a|y   Automatic updates, without interaction.
--I     Prints custom releasenote urls alongside each container with updates in CLI output (requires urls.list).
--l     Only include containers with label set. See readme.
--m     Monochrome mode, no printf colour codes and hides progress bar.
--M     Prints custom releasenote urls as markdown (requires template support).
 -n     No updates, only checking availability.
 -p     Auto-Prune dangling images after update.
--r     Allow checking/updating images created by `docker run`, containers need to be recreated manually.
+-r     Allow updating images for docker run, wont update the container.
--R     Skip container recreation after pulling images.
--s     Include stopped containers in the check. (Logic: docker ps -a).
--t N   Set a timeout (in seconds) per container for registry checkups, 10 is default.
--u     Allow automatic self updates - caution as this will pull new code and autorun it.
--v     Prints current version.
--x N   Set max asynchronous subprocesses, 1 default, 0 to disable, 32+ tested.

-## Dependencies
-
-- Running docker (duh) and compose, either standalone or plugin. (see [Podman fork](https://github.com/sudo-kraken/podcheck))
-- Bash shell or compatible shell of at least v4.3
-  - POSIX `xargs`, usually default but can be installed with the `findutils` package - to enable async.
-- [jq](https://github.com/jqlang/jq)
-  - User will be prompted to install with package manager or download static binary.
-- [regclient/regctl](https://github.com/regclient/regclient) (Licensed under [Apache-2.0 License](http://www.apache.org/licenses/LICENSE-2.0))  
-  - User will be prompted to download `regctl` if not in `PATH` or `PWD`.  
-  - regctl requires `amd64/arm64` - see [workaround](#workaround-for-non-amd64--arm64) if other architecture is used.
-
-## 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`.
-
-```shell
-# 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.
-
-## Configuration
-
-To modify settings and have them persist through updates - copy the `default.config` to `dockcheck.config` alongside the script or in `~/.config/`.  
-Alternatively create an alias where specific flags and values are set.  
-Example `alias dc=dockcheck.sh -p -x 10 -t 3`.
-
-## Notifications
-
-Triggered with the `-i` flag. Will send a list of containers with updates available and a notification when `dockcheck.sh` itself has an update.
-`notify_templates/notify_v2.sh` is the default notification wrapper, if `notify.sh` is present and configured, it will override.
-
-Example of a cron scheduled job running non-interactive at 10'oclock excluding 1 container and sending notifications:
-`0 10 * * * /home/user123/.local/bin/dockcheck.sh -nix 10 -e excluded_container1`
-
-#### Installation and configuration
-
-Set up a directory structure as below.
-You only need the `notify_templates/notify_v2.sh` file and any notification templates
-you wish to enable, but there is no harm in having all of them present.
-
-```shell
- .
-├── notify_templates/
-│   ├── notify_DSM.sh
-│   ├── notify_apprise.sh
-│   ├── notify_bark.sh
-│   ├── notify_discord.sh
-│   ├── notify_generic.sh
-│   ├── notify_gotify.sh
-│   ├── notify_HA.sh
-│   ├── notify_matrix.sh
-│   ├── notify_ntfy.sh
-│   ├── notify_pushbullet.sh
-│   ├── notify_pushover.sh
-│   ├── notify_slack.sh
-│   ├── notify_smtp.sh
-│   ├── notify_telegram.sh
-│   └── notify_v2.sh
-├── dockcheck.config
-├── dockcheck.sh
-└── urls.list         # optional
-```
-
-- Uncomment and set the `NOTIFY_CHANNELS=""` environment variable in `dockcheck.config` to a space separated string of your desired notification channels to enable.
-- Uncomment and set the environment variables related to the enabled notification channels. Eg. `GOTIFY_DOMAIN=""` + `GOTIFY_TOKEN=""`.
-
-It's recommended to only do configuration with variables within `dockcheck.config` and not modify `notify_templates/notify_X.sh` directly. If you wish to customize the notify templates yourself, you may copy them to your project root directory alongside the main `dockcheck.sh` (where they're also ignored by git).  
-Customizing `notify_v2.sh` is handled the same as customizing the templates, but it must be renamed to `notify.sh` within the `dockcheck.sh` root directory.  
-
-#### Snooze feature
-
-Configure to receive scheduled notifications only if they're new since the last notification - within a set time frame.
-
-**Example:** *Dockcheck is scheduled to run every hour. You will receive an update notification within an hour of availability.*  
-**Snooze enabled:** You will not receive a repeated notification about an already notified update within the snooze duration.  
-**Snooze disabled:** You will receive additional (possibly repeated) notifications every hour.  
-
-To enable snooze uncomment the `SNOOZE_SECONDS` variable in your `dockcheck.config` and set it to the number of seconds you wish to prevent duplicate alerts.  
-Snooze is split into three categories; container updates, `dockcheck.sh` self updates and notification template updates.
-
-If an update becomes available for an item that is not snoozed, notifications will be sent and include all available updates for that item's category, even snoozed items.
-
-The actual snooze duration will be 60 seconds less than `SNOOZE_SECONDS` to account for minor scheduling or run time issues.
-
-#### Current notify templates
-
-- 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)

-
-#### Notification channel configuration
-
-All required environment variables for each notification channel are provided in the default.config file as comments and must be uncommented and modified for your requirements.  
-For advanced users, additional functionality is available via custom configurations and environment variables.  
-Use cases - all configured in `dockcheck.config`:  
-(replace `<channel>` with the upper case name of the of the channel as listed in
-`NOTIFY_CHANNELS` variable, eg `TELEGRAM_SKIPSNOOZE`)
-
-- To bypass the snooze feature, even when enabled, add the variable `<channel>_SKIPSNOOZE` and set it to `true`.
-- To configure the channel to only send container update notifications, add the variable `<channel>_CONTAINERSONLY` and set it to `true`.
-- To send notifications even when there are no updates available, add the variable `<channel>_ALLOWEMPTY`  and set it to `true`.
-- To use another notification output format, add the variable `<channel>_OUTPUT` and set it to `csv`, `json`, or `text`. If unset or set to an invalid value, defaults to `text`.
-- To send multiple notifications using the same notification template:
-  - Strings in the `NOTIFY_CHANNELS` list are now treated as unique names and do not necessarily refer to the notification template that will be called, though they do by default.
-  - Add another notification channel to `NOTIFY_CHANNELS` in `dockcheck.config`. The name can contain upper and lower case letters, numbers and underscores, but can't start with a number.
-  - Add the variable `<channel>_TEMPLATE` to `dockcheck.config` where `<channel>` is the name of the channel added above and set the value to an available notification template script (`slack`, `apprise`, `gotify`, etc.)
-  - Add all other environment variables required for the chosen template to function with `<channel>` in upper case as the prefix rather than the template name.
-    - For example, if `<channel>` is `mynotification` and the template configured is `slack`, you would need to set `MYNOTIFICATION_CHANNEL_ID` and `MYNOTIFICATION_ACCESS_TOKEN`.
-
-#### 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.  
-For Markdown formatting also add the `-M` option. (**this requires the template to be compatible - see gotify for example**)  
-
-The output of the notification will look something like this:
-
-```shell
-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.
-
-## Asyncronous update checks with **xargs**; `-x N` option. (default=1)
-
-Pass `-x N` where N is number of subprocesses allowed, experiment in your environment to find a suitable max!  
-Change the default value by editing the `MaxAsync=N` variable in `dockcheck.config`. To disable the subprocess function set `MaxAsync=0`.
-
-## Image Backups; `-b N` to backup previous images as custom (retagged) images for easy rollback
-
-When the option `BackupForDays` is set **dockcheck** will store the image being updated as a backup, retagged with a different name and removed due to age configured (*BackupForDays*) in a future run.  
-Let's say we're updating `b4bz/homer:latest` - then before replacing the current image
-it will be retagged with the name `dockcheck/homer:2025-10-26_1132_latest`
-
-- `dockcheck` as repo name to not interfere with others.
-- `homer` is the image.
-- `2025-10-26_1132` is the time when running the script.
-- `latest` is the tag of the image.
-
-Then if an update breaks, you could restore the image by stopping the container, delete the new image, eg. `docker rmi b4bz/homer:latest`, then retag the backup as latest `docker tag dockcheck/homer:<date>_latest b4bz/homer:latest`.  
-After that, start the container again (now with the backup image active) and it will be updated as usual next time you run dockcheck or other updates.
-
-The backed up images will be removed if they're older than *BackupForDays* value (passed as `-b N` or set in the `dockcheck.config` with `BackupForDays=N`) and then pruned.  
-If configured for eg. 7 days, force earlier cleaning by just passing a lower number of days, eg. `-b 2` to clean everything older than 2 days.  
-Backed up images will not be removed if neither `-b` flag nor `BackupForDays` config variable is set.
-
-Use the capital option `-B` to list currently backed up images. Or list all images with `docker images`.  
-To manually remove any backed up images, do `docker rmi dockcheck/homer:2025-10-26_1132_latest`.  
-
-## Extra plugins and tools
-
-### Using dockcheck.sh with the Synology DSM
-
-If you run your container through the *Container Manager GUI* - only notifications are supported.  
-While if running manual (vanilla docker compose CLI) will allow you to use the update function too.  
-Some extra setup to tie together with Synology DSM - check out the [addons/DSM/README.md](./addons/DSM/README.md).
-
-### 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:
-
-```shell
-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>  
-
-### Zabbix config to monitor docker image updates
-
-If you already use Zabbix - this config will show numbers of available docker image updates on host.  
-Example: *2 Docker Image updates on host-xyz*  
-See project: [thetorminal/zabbix-docker-image-updates](https://github.com/thetorminal/zabbix-docker-image-updates)
-
-### Serve REST API to list all available updates
-
-A custom python script to serve a REST API to get pulled into other monitoring tools like [homepage](https://github.com/gethomepage/homepage).  
-See [discussion here](https://github.com/mag37/dockcheck/discussions/146).
-
-### Wrapper Script for Unraid's User Scripts
-
-A custom bash wrapper script to allow the usage of dockcheck as a Unraid User Script plugin.  
-See [discussion here](https://github.com/mag37/dockcheck/discussions/145).
-
-## Labels
-
-Optionally add labels to compose-files. Currently these are the usable labels:
-
-```yaml
-    labels:
-      mag37.dockcheck.update: true
-      mag37.dockcheck.only-specific-container: true
-      mag37.dockcheck.restart-stack: true
-```
-
-- `mag37.dockcheck.update: true` will when used with the `-l` option only check and update containers with this label set and skip the rest.  
-- `mag37.dockcheck.only-specific-container: true` works instead of the `-F` option, specifying the updated container when doing compose up, like `docker compose up -d homer`.
-- `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).
-
-Adding or modifying labels in compose-files requires a restart of the container to take effect.
-
-## 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):
-
-```shell
-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`).
-
-## 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`.
-
-### Function to auth with docker hub before running
-
-**Example** - Change names, paths, and remove cat+password flag if you rather get
-prompted:
-
-```shell
-function dchk {
-  cat ~/pwd.txt | docker login --username YourUser --password-stdin
-  ~/dockcheck.sh "$@"
-}
-```
-
-## `-r flag` disclaimer and warning
-
 **Wont auto-update the containers, only their images. (compose is recommended)**   
-`docker run` doesn't support using new images just by restarting a container.  
+`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.
-Using the `-r` option together with eg. `-i` and `-n` to just check for updates and send notifications and not update is safe though!
 
-## Known issues
 
-- No detailed error feedback (just skip + list what's skipped).
+### :beetle: Squashed Bugs:
-- Not respecting `--profile` options when re-creating the container.
+- ~~No options for running without updates or auto update.~~
-- Not working well with containers created by **Portainer**.
+- ~~No filter to check only specific containers.~~
-- **Watchtower** might cause issues due to retagging images when checking for updates (and thereby pulling new images).
+- ~~Faulty registry checkups stopped the updates completely.~~
+- ~~No clear checks to skip containers producing errors.~~
+- ~~Multi-digest images didn't correctly check with registry, giving false positives on updates.~~
+- ~~Not working with filenames other than `docker-compose.yml`~~
+- ~~Lists are not alphabetically sorted (due to stacks and other parameters)~~
+- ~~Old `docker-compose` binary-check sometimes returned false error~~
+- ~~Stacks gets updated as whole, even if only one service is chosen.~~
+- ~~Path broken occationally (from inspect) - probably due to old docker-compose binary.~~
+- ~~Script breaks if one of the chosen containers are a `docker run` container.~~
+- ~~Using relative paths for volumes eg. `${PWD}/data:data` will create the volumes where you stand.~~
+- ~~Having no curl/wget leads to corrupt `regctl` without alerting.~~
 
-## Debugging
+### :hammer: Known issues
-
+- ~~No granular choice of what to update (except initial name filter).~~
-If you hit issues, you could check the output of the `extras/errorCheck.sh` script for clues.
+- No detailed error feedback (just skip + list what's skipped) .
-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`.
-
-## License
 
+## `dupc_function.sh`
+Function to quickly check for updates on a single contianer or list of containers by name. **Without the need of pulling**.  
+Preferably placed in `.bashrc` or similar.

-## 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
-dockcheck_images_latest 14
-# HELP dockcheck_images_error Docker images with analysis errors
-# TYPE dockcheck_images_error gauge
-dockcheck_images_error 1
-# HELP dockcheck_images_analyze_timestamp_seconds Last dockercheck run time
-# TYPE dockcheck_images_analyze_timestamp_seconds gauge
-dockcheck_images_analyze_timestamp_seconds 1737924029
-```
-
-Once those metrics are exported they can be used to define alarms as shown below
-
-```
-- alert: dockcheck_images_outdated
-  expr: sum by(instance) (dockcheck_images_outdated) > 0
-  for: 15s
-  labels:
-    severity: warning
-  annotations:

-  annotations:

-    description: "{{ $labels.instance }} has {{ $value }} docker images having an error."
-- alert: dockercheck_image_last_analyze
-  expr: (time() - dockcheck_images_analyze_timestamp_seconds) > (3600 * 24 * 3)
-  for: 15s
-  labels:
-    severity: warning
-  annotations:
-    summary: "{{ $labels.instance }} has not updated the dockcheck statistics for more than  3 days."
-    description: "{{ $labels.instance }} has not updated the dockcheck statistics for more than 3 days."

-# A small guide on getting started with Apprise notifications.
-
-
-## Standalone docker container: [linuxserver/apprise-api](https://hub.docker.com/r/linuxserver/apprise-api)
-
-Set up the docker compose as preferred:
-```yaml
----
-version: "2.1"
-services:
-  apprise-api:
-    image: lscr.io/linuxserver/apprise-api:latest
-    container_name: apprise-api
-    environment:
-      - PUID=1000
-      - PGID=1000
-      - TZ=Etc/UTC
-    volumes:
-      - /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 need to follow the configuration setup (explained in detail in the README).
-Briefly: Copy `default.config` to `dockcheck.config` then edit it to change the following, `APPRISE_URL` matching your environment:
-
-```bash
-NOTIFY_CHANNELS="apprise"
-APPRISE_URL="http://apprise.mydomain.tld:1234/notify/apprise"
-```
-
-That's it!
-___
-___
-
-
-## 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!
