Installing and Using Helm

Install Helm on macOS, Linux, or Windows and learn the basic commands for repositories, releases, and uninstalling charts.

Install Helm

brew install helm

curl https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 | bash

choco install kubernetes-helm

helm repo add bitnami https://charts.bitnami.com/bitnami
helm repo update

helm search repo nginx

helm install my-nginx bitnami/nginx

helm list

helm status my-nginx

helm uninstall my-nginx

Instead of manually pasting dozens of YAML files, Helm can install a packaged stack and still let you customize values.
