Given that Watchtower is potentially unmaintained now, this might be a cool alternative?

Features from their github:
- Extremely fast. Cup takes full advantage of your CPU and is hightly optimized, resulting in lightning fast speed. On my Raspberry Pi 5, it took 3.7 seconds for 58 images!
- Supports most registries, including Docker Hub, ghcr.io, Quay, lscr.io and even Gitea (or derivatives)
- Doesn’t exhaust any rate limits. This is the original reason I created Cup. I feel that this feature is especially relevant now with Docker Hub reducing its pull limits for unauthenticated users.
- Beautiful CLI and web interface for checking on your containers any time.
- The binary is tiny! At the time of writing it’s just 5.4 MB. No more pulling 100+ MB docker images for a such a simple program.
- JSON output for both the CLI and web interface so you can connect Cup to integrations. It’s easy to parse and makes webhooks and pretty dashboards simple to set up!
Is there anything similar, but for k8s?
I use fluxcd with helmrelease’s which auto update the helm release. If the helm chart versions specify container versions, then updating the helm chart updates the containers in the deployments.
But for raw deployments, I found this, but not much else.
Interesting. I’m using Argo, there may be something similar for it
Similar in which regard? Containers can be covered by this, but I’m assuming you mean for things like charts?
Meaning that I get to see my deployment and check if the image is updated. If not, change the deployment image
