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.

[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.

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.

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.

Exchanging data between other processes
And the Go side: https://github.com/containers/skopeo/blob/main/cmd/skopeo/proxy.go

Top Docker alternatives for 2022
Skopeo is yet another tool developed by RedHat for various operations on container images and image repositories. Skopeo can be used as an accompanying tool for Podman and Buildah, which are both intended to inspect images, transfer them from one registry to another, and bulk delete them if necessary.
- How are you switching from dockerd to containerd in Kubernetes ? (Docker-in-docker)
Diun
- Is there a tool to monitor container images version locally and notify if there are updates?
-
PSA - Run "docker image prune" once in a while.
Thanks, I used to use it. I moved to using diun to just notify of updates but not apply them though.
-
Update containers/images to latest version in Docker Desktop (windows)
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.
-
Seatch for apps updates notifier app
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.
-
Is there a centralized Docker Container Management for updating containers?
diun is very similar to that, but it doesnt auto-update, just notifies but does that very well imo.
-
Docker Swarm: automatically update service when new image is released
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.
-
Docker container update notifier - watchCat
Seems very similar to diun but i like the feature to put containers into groups.
-
Watchtower: understand which containers have problem from the log
If you want notifications on new image updates, try diun.
-
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!
-
What to use with Docker?
I would instead use DIUN, which will notify you when there are updates so you can make your own decisions: https://github.com/crazy-max/diun
