Overview
Revised for Helm 3
Caching repositories locally is useful when installing charts and specifying the chart to be installed using the name of the locally cached repository and the name of the chart. However, charts can be installed directly from the remote repository, without having to add (cache) the repository locally. The repositories are cached locally with helm repo add command, but the cache is not automatically kept up to date in any way, it has to be explicitly updated with helm repo update.
List Repositories Helm is Configured With
helm repo list
List All Charts in a Repository
Add a New Repository
helm repo add <repository-name> <repository-url> [--username <username>] [--password <password>]
helm repo add dev https://example.com/dev-charts
If the repository is password protected, the advantage of caching the repository remote while using --username and --password is that the username and the password are cached and not to have specified every time the chart is installed.Note that the repository must expose an index.yaml, otherwise the above command will fail with .../index.yaml 404 Not Found.
helm repo add incubator https://kubernetes-charts-incubator.storage.googleapis.com/
Update the Local Repository Cache
The command reaches out to remote repositories Helm installation is configured with and gets the latest information about charts. Information is cached locally
