2.3.0 · 1y+

🌷 Spring is here, and a new version of Helm has bloomed. Helm 2.3.0 is packed full of features and fixes.

Our community keeps growing, and we'd love to have you participate.

Install! Upgrade!

Download Helm 2.3. The common platform binaries are here:

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

Note: On Kubernetes 1.6, you will need to decide how to configure your RBACs for Tiller.

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.

Introducing the Helm Plugin Manager

We introduced Helm plugins in 2.1.0. And now we're bringing plugins to a new level with the Helm Plugin Manager. Installing plugins is now as easy as this:

$ helm plugin install https://github.com/adamreese/helm-last

The above will install the helm last plugin directly from GitHub. You can view your plugins with helm plugin list and remove plugins with helm plugin remove.

Plugin developers get a few new goodies, too, including a workflow for local development and a hook system for running special commands on install and delete. We're creating a list of Helm plugins to help the community find useful extensions.

A Garden of New Template Functions

We've been hard at work making the Chart template system more powerful.

  • There is now a required template function for marking a parameter as required.
  • Along with toYaml and toJson, we also have a toToml conversion function. ConfigMap generation just got a lot easier.
  • Sprig (our template function library) has dozens of new functions, many for improving flow control. And the library has new documentation too.

Hoisting Values from Child Charts to Parent Charts

It is now possible to hoist values from a child chart to its parent. Building on 2.2.0's changes to requirements.yaml, Helm 2.3 allows chart developers to specify child values that should be extracted from the child chart and inserted into the parent.

This makes it possible to share variables upward without surprises. Check out the docs for this new feature.

And More TLS!

In Helm 2.2, we made it possible to use TLS to secure your chart repositories. With 2.3 we now support TLS encryption between helm and tiller (vai SSL gRPC). To get started with this, run helm init --help and take a look at the new TLS flags.

Other Features Have Sprung Up

We've included many more features in Helm.

  • Hooks can now be "weighted", giving chart authors the ability to run hooks in order
  • The --reuse-values flag makes it possible to run a helm upgrade and re-use the old values
  • Two new fields have been added to Chart.yaml: appVersion for specifying the version of an application that a chart provides, and deprecated to indicate that a chart is no longer maintained.
  • A --skip-refresh flag has been added to helm repo and helm init to prevent Helm from re-fetching repository index files.
  • The plugin system can be disabled via environment variable.
  • helm serve now has a --url parameter for specifying a base URL.

Pile on a few dozen bug fixes and documentation changes, and you'll see how our always growing community has been hard at work.

What's Next?

  • Patch releases will begin with Helm 2.3.1, focused on bug fixes and documentation changes.
  • Helm 2.4.0 is the next major release. The planned major features are:
    • Migration to the Kuberenetes 1.6 library
    • New Tiller-side plugins (called Rudders)
    • Helm Authentication
    • Protocol hooks for Helm plugins
