example-voting-app VS Diun

Definitely, here’s an example app using Docker and microservices in Python, NodeJS and .NET https://github.com/dockersamples/example-voting-app

Hi! I used dockersamples/example-voting-app few times ago when I started learning K8s (and it was really helpful thanks community). However, I think it's can be way more complete and modern.

https://github.com/dockersamples/example-voting-app/blob/master/docker-compose.yml or non swarm example.

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

https://crazymax.dev/diun/ and docker compose

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.
