Install Helm from a Package Manager
The Helm community also contributes and maintains packages to several package managers. These are not officially supported, but are generally up-to-date. Here is how to install Helm using Homebrew (macOS), Chocolatey (Windows), and Apt (Debian/Ubuntu).
Add a Helm Chart Repository
After installing Helm, add a Helm chart repository. To add and access the official Helm chart repository, enter the following command:
helm repo add bitnami https://charts.bitnami.com/bitnami
Install a Helm Chart
After adding the repo, you can install your first Helm chart.
Update local information about the available charts. Enter the following command:
helm repo update
As an example, you can install a MySQL chart creating a Release. A Release is an instance of a chart running in a cluster. This release is named mydb. Enter the following command:
helm install mydb bitnami/mysql
List all installed charts and check their status. Enter the following command:
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION mydb default 1 2022-02-06 18:06:24.41517 +0200 CEST deployed mysql-8.8.25 8.0.28
