Master Helm Repository Management: Add, Update, Search & Secure Charts

Overview

Helm repositories store packaged Helm charts (.tgz) and an index.yaml that lists chart metadata; they function like traditional package manager repositories (apt, yum) and are served over HTTP.

Common Repository Types

Official repository (now archived; use Artifact Hub to discover charts)

Community repositories such as Bitnami and Jetstack

Private repositories for internal charts

Typical Helm Repository Commands

Add a repository

helm repo add [repo-name] [repo-url]

Update repository index

helm repo update

List configured repositories

helm repo list

Remove a repository

helm repo remove [repo-name]

Search charts in repositories

helm search repo [keyword]

Show chart versions in a repository

helm search repo [chart-name] --versions

Pull a chart from a remote repository

helm pull [chart] --version [ver] --untar --destination [path] --repo [repo-url]

Private Repository Commands

Create repository index

helm repo index [directory] --url [repo-url]

Push a chart to a private repository

helm push [chart-path] [repo-name]
