Having delved into Helm’s foundational aspects, it’s time to put Helm to work in deploying and managing applications. In this fifth part of the “Helm for Beginners” series, we’ll focus on practical applications. Learn how to effortlessly install pre-built charts from public repositories and master the art of updating, rolling back, and deleting releases. Let’s navigate the Helm landscape and empower you to efficiently manage your Kubernetes applications.

Installing Pre-Built Charts

1. Exploring Helm Hub:
– Helm Hub serves as a central repository for Helm charts, housing a plethora of pre-built charts for popular applications. Explore Helm Hub to discover charts that suit your needs.

2. Installing a Chart:
– Use the Helm CLI to install a pre-built chart from Helm Hub. Specify the chart name and, if necessary, provide customization values.

helm install my-release stable/nginx-ingress

3. Verifying the Installation:
– Confirm the successful deployment of your chart by checking the status of the release.

helm status my-release

Managing Helm Releases

1. Updating Releases:
– Helm allows for easy updates to your releases. Adjust values in `values.yaml` or provide them as arguments during the update.

helm upgrade my-release stable/nginx-ingress

2. Rolling Back Releases:
– In case of issues with an update, Helm enables seamless rollbacks to a previous release version.

helm rollback my-release 1

3. Deleting Releases:
– When an application is no longer needed, use the Helm CLI to delete the release, freeing up resources.

helm uninstall my-release

Best Practices for Release Management

1. Consistent Release Names:
– Adopt a consistent naming convention for releases to enhance clarity and organization.

2. Versioning:
– Version your releases to facilitate reproducibility and ensure consistency across environments.

3. Backup Values.yaml:
– Before updates, backup your `values.yaml` file to preserve the configuration state.


Congratulations! You’ve successfully installed pre-built charts and mastered the art of managing Helm releases. As you continue your Helm journey, these skills will prove invaluable in deploying and maintaining Kubernetes applications. In the upcoming parts of this series, we’ll delve into advanced Helm features, including Helm hooks for lifecycle events and securing Helm deployments. Stay tuned for more insights and hands-on guidance that will elevate your Helm expertise!
