DCW VS Diun

To "mass-check and mass-update" containers from the commandline, dockcheck is very light and useful. A simple dockcheck.sh -a -p for example would check all deployed containers for image updates and if there are any, pull them, then restart the container and at the end, cleanup unused images to free up diskspace. There is also a version with a web interface, DCW.

DCW (dockcheck-web) is based on the above dockcheck but has a web-ui.

If you want to update images, try dockcheck or DCW.

Checkout dockcheck-web A webpage showing available image updates for your running containers.

Hi, I will start pushing the new update for beta soon. Just finished the major changes for the exporters. It will be a new image and a secondary image for the exporter. Keep and eye on my now hidden repo palleri/dcw to be public.

Check out the new image with exporter functionality. https://github.com/Palleri/DCW (multiple instances)

Thanks, I used to use it. I moved to using diun to just notify of updates but not apply them though.

Similar to Watchtower but without the option to auto-update containers, just notifying is diun. But imo it does that better and more reliable than Watchtower does. You can get notified by Email, Discord, Pushover, Telegram and many more options.

If your apps are container images, then there are tools like diun, watchtower and whatsupdocker, those can watch the image repository (like Docker Hub) and notify you if a new/updated image has been found. Some can even download and auto-update for you, but that comes at some risk of course.

You might want to have a look at https://crazymax.dev/diun/ which is purpose built for what you're trying to do (notify when an update is available, but not install).

Watchtower is inferior to a project like DIUN this way. Because with double you can actually be notified by newer image versions and act accordingly. But automatic updates (which latest is aswell) are bad practice.

diun is very similar to that, but it doesnt auto-update, just notifies but does that very well imo.

I use https://crazymax.dev/diun/ to send notifications of new images. I also hook it into webbooks with CI for mirroring images, but you should be able to use something like portainer webhooks to auto pull images.
