Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Release Watcher with UI
Argus sounds like it will do a lot/most/all of what you're looking for. Super easy to set up with Docker. I had it running for quite a while but just moved everything to either Github release notification emails or diun (docker image update notifier). No real reason for my switch besides laziness/familiarity. Check it out!

Any tool you use to track all your tools/library/platform/framework/language release version?
We've recently implemented https://github.com/release-argus/Argus to keep track of all docker images that need regular upgrades.

Our Favorite Tools for Monitoring Container Updates
https://github.com/release-argus/Argus is another alternative

How do you update your containers ?
Agreed. Does everything watchtower does and gives you a web page to view configuration of whatsupdocker and available container updates. Can monitor only or upgrade. Also has a docker compose trigger to perform upgrades. Might also look at Argus to monitor application versions.

Monitoring for Docker container updates?
Fantastic! This is exactly what I’ve been looking for. Link for anyone interested - check out the demo.
- Reminder: Update Your Apps Regularly
-
Monitoring image updates when not using :latest!
Take a look at Argus. I use it to monitor the application version (not a container tag). I get notifications via mailrise (SMTP gateway for apprise) which then go to Gotify and Discord. I have webhooks setup to run scripts so I can approve the update from the Argus app to automate the update. You can also have it set to auto approve.

A better, faster approach to downloading docker images without docker-pull: Skopeo
I decided to go searching for an alternative means to pull a docker image. In my search I discovered Skopeo, an alternative method to download Docker images that proved to be surprisingly effective. It not only downloaded the image faster, it also allowed me to save my image in a tar file, which means you can pull an image on one system and share that image to another system, loading it easily to docker instance on that system. This can be very beneficial if you have multiple systems and don't want to download an image multiple times.

[OC] Update: dockcheck - Checking updates for docker images without pulling - automatically update containers by choice.
But I'd suggest looking into if it's solved by other tools already, like regclient/regclient and their regsync features or something like containers/skopeo.

Wrapping Go CLI tools in another CLI?
Have a use case where we have a CLI (built with cobra) for our dev teams which can execute common tasks. One of those tasks we want to implement is to copy docker images from the internet to our internal registry. A tool such as skopeo can do this and much more. Instead of essentially re-writing the functionality directly into our CLI we'd like to embed it. This would also negate the need for the dev teams to manage multiple CLI tools.

Rails on Docker · Fly
Self hoisting here, I put this together to make it easier to generate single (extra) layer docker images without needing a docker agent, capabilities, chroot, etc: https://github.com/andrewbaxter/dinker
Caveat: it doesn't work on Fly.io. They seem to be having some issue with OCI manifests: https://github.com/containers/skopeo/issues/1881 . They're also having issues with new docker versions pushing from CI: https://community.fly.io/t/deploying-to-fly-via-github-actio... ... the timing of this post seems weird.
FWIW the article says
> create a Docker image, also known as an OCI image
I don't think this is quite right. From my investigation, Docker and OCI images are basically content addressed trees, starting with a root manifest that points to other files and their hashes (root -> images -> layers -> layer configs + files). The OCI manifests and configs are separate to Docker manifests and configs and basically Docker will support both side by side.

How are you building docker images for Apple M1?
skopeo is another tool worth looking into. we've started deploying amd and arm nodes into our k8s clusters, and this tool was incredibly easy to build around for getting multi-arch images into our container registry.

Get list of image architectures
I would use skopeo, the tool is quite handy for working with remote images. https://github.com/containers/skopeo

Implement DevSecOps to Secure your CI/CD pipeline
Using distroless images not only reduces the size of the container image it also reduces the surface attack. The need for container image signing is because even with the distroless images there is a chance of facing some security threats such as receiving a malicious image. We can use cosign or skopeo for container signing and verifying. You can read more about securing containers with Cosign and Distroless Images in this blog.

ImagePullPolicy: IfNotPresent - (image doesn’t exist in repo) - Is it possible to pull the micro service image from an EKS node and then push to repo?
Look at using tools like skopeo or crane
-
Monitoring image updates when not using :latest!
You could try some commandline tool like skopeo to fetch the image tags regularly and do some shell magic to notify you on any change you want

Containers without Docker (podman, buildah, and skopeo)
This is what Podman, an open-source daemonless and rootless container engine, was developed with in mind. Podman runs using the runC container runtime process, directly on the Linux kernel, and launches containers and pods as child processes. In addition, it was developed for the Docker developer, with most commands and syntax seamlessly mirroring Docker's. Buildah, an image builder, and Skopeo, the image utility tool, are both complimentary to Podman as well, and extend the range of operations able to be performed.
