This mid-summer Helm release includes several fixes to the Helm 2.5 release. Most notably:

  • The deadlock problem with Tiller has been found and fixed. A huge thanks to the dozen community members who submitted use cases and data to help us find the problem.
  • The helm get manifest and helm get value commands are now working properly.
  • Plugins will now receive the correct value for $HELM_HOME regardless of how the home directory was set.

Helm v2.5.1 is tested on Kubernetes 1.5-1.7. However, the latest Kubernetes 1.7 features (e.g. custom type definitions) are not supported in this release. Full Kubernetes 1.7 support is coming in Helm 2.6.

Our community is one of the fastest growing Kubernetes projects. We'd love to have you as a part!

  • Join the discussion in Kubernetes Slack:
    • #helm-users for questions and just to hang out
    • #helm-devs for discussing PRs, code, and bugs
  • Hang out at the Public Developer Call: Thursday, 9:30 Pacific via Zoom
  • Test, debug, and contribute charts: GitHub/kubernetes/charts

Installation and Upgrading

Download Helm 2.5.1. The common platform binaries are here:

Once you have the client installed, upgrade Tiller with helm init --upgrade.

The Quickstart Guide will get you going from there. For upgrade instructions or detailed installation notes, check the install guide. You can also use a script to install on any system with bash.

Breaking Changes

In this release, we fixed a bug that caused extra empty fields to be added to a requirements.yaml file. As a result, in some cases this fix will result in a regeneration of the requirements lock file. This is not technically a breaking change, but may result in surprising behavior.

What's Next

  • 2.6.0 is the next feature release. It is nearing completion.
