Container Image Support

When containers took off in popularity, everyone was putting their container images meant for general public consumption on Docker Hub. This made it easy to discover container images. You could search Docker Hub or use docker search in your console.

With the rise of the Open Container Initiative (OCI) and many different companies operating container registries this all changed. Images meant for public consumption could be in GitHub Container Registry, the Amazon ECR Public Gallery, and many other registries. This change distributed where images were hosted.

Distributed images meant there was no longer a centralized search solution to look for container images. Discovery of images became more difficult.

Today, we are please to share that Artifact Hub now supports listing and searching for container images.

Changelogs

changelog

Changelogs are useful for consumers of an artifact or package. They let consumers see, at a glance, what has changed without needing to read or understand the source. Reading the source doesn’t convey intent as well as a changelog, either. To understand intent, you often need to look at issues and commit messages for some additional context. All of that can be summarized in a changelog.

Annotations provide an easy way to convey this information. Wouldn’t it be great to check these annotations before cutting a release? Now you can with the ah command line tool.

Helm Values Schema Reference

Helm v3 introduced schemas for values. The schemas are written as JSON Schemas and put in a chart in a file named values.schema.json that goes right alongside values.yaml files. Wouldn’t it be great if there was a way to easily use these files to understand the values in a chart? Artifact Hub provides just that with its Values Schema Reference.
