Kubernetes has been a cornerstone in the world of container orchestration for some time now, and Helm is often referred to as “The Kubernetes Package Manager.” In 2025, Helm remains an essential tool for developers who are managing applications on Kubernetes. This article will explore some of the common Helm commands that every developer should know to effectively work with Kubernetes in 2025.
What is Helm?
Helm is a powerful tool that streamlines the deployment and management of applications on Kubernetes. By using Helm charts, developers can define, install, and upgrade complex Kubernetes applications. Helm serves to improve your Kubernetes deployment process by allowing you to leverage reusable application templates and manage dependencies efficiently.
Common Helm Commands
1. Installing Helm
Before you start using Helm, you need to install it. The installation process is straightforward:
1 2 3 |
curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3 chmod 700 get_helm.sh ./get_helm.sh |
2. Creating a New Helm Chart
When you need to create a new Helm chart, use the following command:
1
|
helm create [chart-name]
|
This command generates a project structure with the necessary files to get started with your chart.
3. Installing a Helm Chart
To deploy a Helm chart, use the command:
1
|
helm install [release-name] [chart-name]
|
Replace [release-name] with a name for your release and [chart-name] with the name of the chart you want to install.
4. Listing Installed Helm Releases
View all the installed releases in your current namespace with:
1
|
helm list
|
Add --all-namespaces to list releases across all namespaces.
5. Upgrading a Helm Release
When your application changes and you need to update the release, use:
1
|
helm upgrade [release-name] [chart-name]
|
This command will update the deployment with any new changes made to the chart.
6. Deleting a Helm Release
If you need to remove a release, you can do so easily with:
1
|
helm uninstall [release-name]
|
This command will delete the release and all its associated resources.
7. Helm Dependencies
Managing dependencies is crucial. To update dependencies for a chart, use:
1
|
helm dependency update [chart-name]
|
8. Helm Template
Render Kubernetes templates locally and view the resulting manifests with:
1
|
helm template [chart-name]
|
This command allows you to see what Helm will install before actually deploying it.
