What is Helm?

helm is the open source package manager for Kubernetes.

It works like other package mangers (brew, yum, npm etc) where there’s one or more repositories with packages to install (called charts in helm to keep with the nautical kubernetes theme) which can be searched/installed and upgraded.

A helm chart is basically a versioned tarball of kubernetes yaml which can be easily installed on any kubnernetes cluster.

Helm supports composition (a chart can contain other charts) via the requirements.yaml file.
