## :mag_right: `dockcheck.sh`
|
|
```
|
|
$ ./dockcheck.sh -h
|
|
Syntax: dockcheck.sh [OPTION] [part of name to filter]
|
|
Example: dockcheck.sh -y -d 10 -e nextcloud,heimdall
|
|
|
|
Options:
|
|
-a|y Automatic updates, without interaction.
|
|
-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.
|
|
-h Print this Help.
|
|
-i Inform - send a preconfigured notification.
|
|
-m Monochrome mode, no printf color codes.
|
|
-n No updates, only checking availability.
|
|
-p Auto-Prune dangling images after update.
|
|
-r Allow updating images for docker run, wont update the container.
|
|
-s Include stopped containers in the check. (Logic: docker ps -a)
|
|
```
|
|
|
|
### Basic example:
|
|
```
|
|
$ ./dockcheck.sh
|
|
. . .
|
|
Containers on latest version:
|
|
glances
|
|
homer
|
|
|
|
Containers with updates available:
|
|
1) adguardhome
|
|
2) syncthing
|
|
3) whoogle-search
|
|
|
|
Choose what containers to update:
|
|
Enter number(s) separated by comma, [a] for all - [q] to quit:
|
|
```
|
|
Then it proceedes to run `pull` and `up -d` on every container with updates.
|
|
After the updates are complete, you'll get prompted if you'd like to prune dangling images.
|
|
|
|
## :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, copy it to `notify.sh`, modify it to your needs!
|
|
Current templates:
|
|
- Synology [DSM](https://www.synology.com/en-global/dsm)
|
|
- Email with [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)
|
|
- Read the [QuickStart](extras/apprise_quickstart.md)
|
|
- [ntfy.sh](https://ntfy.sh/) - HTTP-based pub-sub notifications.
|
|

## :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`).
|
|
|
|
## :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.
|
|
|
|
## :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.
