Helm introduced full support for storing charts within OCI registries as a distribution method beginning in version 3.8, and while this feature has been available for some time now, there is more underneath the hood than one may realize to make this capability all possible. A number of concepts, working in unison, make it possible to store content aside from traditional container images within OCI registries. This article will explore one of these important concepts, Media Types, their purpose, and how Helm’s own set of Media Types make it possible to extend the storage of charts beyond standard chart repositories to OCI registries.

In the past year, the team at Ada Logics has worked on integrating continuous fuzzing into the Helm core project. This was an effort focused on improving the security posture of Helm and ensuring a continued good experience for Helm users. The fuzzing integration involved enrolling Helm in the OSS-Fuzz project and writing a set of fuzzers that further enriches the test coverage of Helm. In total, 38 fuzzers were written, and nine bugs were found (with eight fixed so far), demonstrating the work’s value for Helm both short term and long term. All fuzzers were implemented by way of Go-fuzz and are run daily by OSS-Fuzz against the latest Helm commit to make sure Helm is continuously fuzz tested. The full report of the engagement can be found here.

The Helm project is happy to welcome yxxhero as our newest maintainer for the helm-www repo!

The Helm maintainers are excited to be headed to KubeCon + CloudNativeCon NA '22 in Detroit, MI in a couple of weeks! As always, there will be a few different places you can find us!

We regularly get questions from people who want tools or methods to manage their Helm releases in an environment. This post provides some insight and direction to help people get started.

With the release of Helm 3.8.0, Helm is able to store and work with charts in container registries, as an alternative to Helm repositories. This feature, which used to be an experimental feature, is now generally available.

The Helm organization is thrilled to introduce Karen Chu as the latest member of the Helm org maintainers. She will be the ninth committee member. Karen has been active in the Helm ecosystem since day one when Rimas, Jack, and I first started the project. She was instrumental in Helm's early branding, organized both of the Helm Summits, and leads Helm's community management team. You may also know her from her Helm-adjacent work as the co-creator of the Illustrated Children's Guide to Kubernetes series or her role as a CNCF ambassador.

Meet Helm's newest org maintainer: Martin Hickey. Martin has been a longtime Helm project maintainer. He was instrumental in the development of Helm 3, and has been one of the most active maintainers on the project. He is also one of the creators of the Helm 2-to-3 migration plugin.

Helm has now completed a second security audit, funded by the CNCF. The first audit focused on the source code for the Helm client along with the process Helm uses to handle security. The second audit, performed by Trail of Bits, looked at the source code for the Helm client along with a threat model for the use of Helm.

A year ago, we introduced Helm 3, a major evolution in Helm's development. And we announced at that time that Helm 2 would receive patches and security updates for a year.

Here we are, one year later. Friday the 13th, 2020 seems like a fitting day to end support for a major version. And today, we are announcing the official end of support for Helm 2. The charts repository is also now read-only, with no further changes.
