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.

A gopher’s journey to the center of container images
I also explored another module, go-containerregistry, in order to build images without root privileges. The approach is completely different, and we can manipulate each component of the container image separately. This can present an advantage, if you're looking for a way to fine tune things.

Skip build if "${CI_REGISTRY_IMAGE}:${CI_COMMIT_SHORT_SHA}" exists on container registry
Use crane ls in a different job to check the tags in the registry. Create an artifact from its output that you evaluate in your kaniko job to check if the build should run or not.

Docker: We’re No Longer Sunsetting the Free Team Plan
Multi-arch builds are easy to "transfer" IMHO
crane cp docker.io/openfaas/gateway:0.10.0 ghcr.io/openfaas/gateway:0.10.0
If you've not used it yet - do take a look. Crane doesn't pull the images into a local Docker library for re-tagging and re-pushing.

pretty sure the crane being referred by alex is this one: https://github.com/google/go-containerregistry/tree/main/cmd/crane

Crafting container images without Dockerfiles
This is one of my absolute favorite topics. Pardon me while I rant and self-promote :D
Dockerfiles are great for flexibility, and have been a critical contributor to the adoption of Docker containers. It's very easy to take a base image, add a thing to it, and publish your version.
Unfortunately Dockerfiles are also full of gotchas and opaque cargo-culted best practices to avoid them. Being an open-ended execution environment, it's basically impossible to tell even during the build what's being added to the image, which has downstream implications for anybody trying to get an SBOM from the image for example.
Instead, I contribute to a number of tools to build and manage images without Dockerfiles. Each of them are less featureful than Dockerfiles, but being more constrained in what they can do, you can get a lot more visibility into what they're doing, since they're not able to do "whatever the user wants".
1. https://github.com/google/go-containerregistry is a Go module to interact with images in the registry and in tarballs and layouts, in the local docker daemon. You can append layers, squash layers, modify metadata, etc.
2. crane is a CLI that uses the above (in the same repo) to make many of the same modifications from the commandline. `crane append` for instance adds a layer containing some contents to an image, entirely in the registry, without even pulling the base image.
3. ko (https://ko.build) is a tool to build Go applications into images without Dockerfiles or Docker at all. It runs `go build`, appends that binary on top of a base image, and pushes it directly to the registry. It generates an SBOM declaring what Go modules went into the app it put into the image, since that's all it can do.
4. apko (https://apko.dev) is a tool to assemble an image from pre-built apks, without Docker. It's capable of producing "distroless" images easily with config in YAML. It generates an SBOM declaring exactly what apks it put in the image, since that's all it can do.
Bazel's rules_docker is another contender in the space, and GCP's distroless images use it to place Debian .debs into an image. Apko is its spiritual successor, and uses YAML instead of Bazel's own config language, which makes it a lot easier to adopt and use (IMO), with all of the same benefits.
I'm excited to see more folks realizing that Dockerfiles aren't always necessary, and can sometimes make your life harder. I'm extra excited to see more tools and tutorials digging into the details of how container images work, and preaching the gospel that they can be built and modified using existing tooling and relatively simple libraries. Excellent article!

A Gentle Introduction to Containerization and Docker
There are a lot of docker-compatible registries almost every cloud provider has its registry but for this article, we will use the docker registry called docker hub. Go to the website create a new account and sign in then you can push or pull images.
What are some alternatives?
skopeo - Work with remote images registries - retrieving information, images, signing content
rook - Storage Orchestration for Kubernetes
regclient - Docker and OCI Registry Client in Go and tooling using those libraries.
kubernetes - Production-Grade Container Scheduling and Management
container-diff - container-diff: Diff your Docker containers
chartmuseum - helm chart repository server
image-spec - OCI Image Format
Harbor - An open source trusted cloud native registry project that stores, signs, and scans content.
gcr-cleaner - Delete untagged image refs in Google Container Registry or Artifact Registry
Docker Compose - Define and run multi-container applications with Docker
docker-tools - This is a repo to house some common tools for our various docker repos.
