Helm: List Repos & Charts in Repo

Helm, the package manager for Kubernetes, provides a convenient way to manage and deploy applications on Kubernetes clusters. One of Helm's essential features is the ability to list repositories and charts available within those repositories. This functionality allows users to explore available charts and install them easily. In this article, we will delve into the Helm command for listing repositories and charts within a repository, providing step-by-step instructions and examples.

Listing Repositories:

To begin, let's take a look at how to list repositories using Helm. Repositories are a collection of charts that are packaged together and made available for installation.

Command:
To list the repositories, use the following Helm command:

helm repo list

Step-by-Step Instructions:

Follow these steps to list the repositories in Helm:

Step 1: Open your terminal or command prompt.

Step 2: Ensure you have Helm installed and properly configured.

Step 3: Run the command helm repo list.

Step 4: Helm will retrieve the list of repositories configured on your system and display the results.

Example:

$ helm repo list
NAME        	URL                                             
stable      	https://charts.helm.sh/stable
local       	http://localhost:8080/charts

The output will show the name and URL of each repository configured in your Helm environment.

Listing Charts within a Repository:

After listing the repositories, you may want to explore the charts available within a specific repository. Helm provides a command to list the charts within a repository.

Command:
To list the charts within a repository, use the following Helm command:

helm search repo <repository-name>

Step-by-Step Instructions:

Here are the steps to list charts within a repository using Helm:

Step 1: Open your terminal or command prompt.

Step 2: Run the command helm search repo <repository-name>, replacing <repository-name> with the actual name of the repository you want to explore.

Step 3: Helm will search the specified repository and display the available charts along with their versions and descriptions.

Example:

$ helm search repo stable
NAME                           	CHART VERSION	APP VERSION	DESCRIPTION
