Update the Chart Repository

This workshop has been deprecated and archived. The new Amazon EKS Workshop is now available at www.eksworkshop.com.

Helm uses a packaging format called Charts. A Chart is a collection of files and templates that describes Kubernetes resources.

Charts can be simple, describing something like a standalone web server (which is what we are going to create), but they can also be more complex, for example, a chart that represents a full web application stack, including web servers, databases, proxies, etc.

Instead of installing Kubernetes resources manually via kubectl, one can use Helm to install pre-defined Charts faster, with less chance of typos or other operator errors.

Chart repositories change frequently due to updates and new additions. To keep Helm’s local list updated with all these changes, we need to occasionally run the repository update command.

To update Helm’s local list of Charts, run:

# first, add the default repository, then update
helm repo add stable https://charts.helm.sh/stable
helm repo update

And you should see something similar to:


Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "stable" chart repository
Update Complete. ⎈ Happy Helming!⎈

Next, we’ll search for the nginx web server Chart.
