Install and Configure Helm Charts

Beginner10 minTrending

Install applications from Helm chart repositories, customize values, and verify successful deployments in your Kubernetes cluster.

Prerequisites

-Helm 3 installed
-kubectl configured with cluster access

Steps

Add the chart repository

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

Always run 'helm repo update' after adding a repo to fetch the latest chart index.

Search for available charts

Browse the repository to find the chart you want to install.

$ helm search repo bitnami/nginx --versions | head -10

Install a chart with default values

Deploy a chart into your cluster with a named release.

$ helm install my-nginx bitnami/nginx --namespace web --create-namespace

Use --create-namespace to automatically create the target namespace if it does not exist.

Verify the deployment

Check that the release was deployed successfully and pods are running.

$ helm status my-nginx --namespace web

List all installed releases

View all Helm releases across namespaces.

$ helm list --all-namespaces
