About Helm
Helm is the package manager for Kubernetes. It helps teams find, install, upgrade and roll back applications that run on a Kubernetes cluster.
What it does
Helm packages a Kubernetes application as a chart, which is a set of templates and settings that define the resources the app needs. Charts can be versioned, shared and hosted on public or private servers. Helm upgrades installed releases in place and can return a release to an earlier version when a change goes wrong.
Key features
- Charts that bundle Kubernetes resources
- In-place upgrades of installed apps
- Roll back to an earlier release
- Share charts on public or private servers
Who it's for
DevOps engineers and developers who deploy the same application to several Kubernetes environments. Teams that want to stop copying Kubernetes manifests by hand will find charts useful for keeping setups consistent.
Pricing and good to know
Helm is open source under the Apache-2.0 licence and is free to use. It is a graduated project of the CNCF. It can be installed with Homebrew, Chocolatey, Scoop or Snap, or as a downloaded binary, and public charts are listed on Artifact Hub.
