Helm, the package manager for Kubernetes that contains information sufficient for installing, upgrading and managing a set of Kubernetes resources into a Kubernetes cluster. Helm packages are called charts. A Helm chart encapsulates YAML definitions, provides a mechanism for configuration at deploy-time and allows you to define metadata and documentation that might be useful when sharing the package.
To install Helm run Helm's installer script in a terminal:
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh
There are several other ways to install Helm as well, you can find it here.
You can verify that you have the correct version and that it installed properly by running:
helm version
If helm is initialised properly you will get output for helm version something like:
version.BuildInfo{Version:"v3.1.2", GitCommit:"d878d4d45863e42fd5cff6743294a11d28a9abce", GitTreeState:"clean", GoVersion:"go1.13.8"}
