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. Read More…

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.

In this new role, Martin will help shape not just Helm, but the many projects that are hosted together with Helm. Read More…

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. Read More…
