Helm: Download Chart & Save Locally

Helm Download Chart alt=

Helm is a powerful package manager for Kubernetes, which helps in the deployment and management of applications. It streamlines the installation and management of Kubernetes applications and provides a mechanism for versioning and rollbacks. In this article, we will discuss how to download Helm charts and save them locally.

Downloading Helm Charts

To download a Helm chart, you need to use the helm fetch command. This command downloads the chart and saves it to your local machine.

The basic syntax of the helm fetch command is as follows:

$ helm fetch [chart-name] --untar=true --untardir=[destination-directory]

Here, [chart-name] is the name of the chart you want to download. The --untar=true option tells Helm to extract the chart from the archive, and the --untardir option specifies the directory where the chart should be saved.

For example, to download the stable/nginx-ingress chart and save it to the /tmp directory, you would use the following command:

$ helm fetch stable/nginx-ingress --untar=true --untardir=/tmp

This command downloads the stable/nginx-ingress chart and saves it to the /tmp/nginx-ingress directory.

Downloading Specific Chart Version

Sometimes you may want to download a specific version of a chart. To do this, you need to specify the version number with the helm fetch command.

For example, to download version 1.36.0 of the stable/nginx-ingress chart, you would use the following command:

$ helm fetch stable/nginx-ingress --version 1.36.0 --untar=true --untardir=/tmp

This command downloads version 1.36.0 of the stable/nginx-ingress chart and saves it to the /tmp/nginx-ingress directory.

Downloading Chart from Specific Repository

By default, Helm searches for charts in the official Helm repository. However, you can also download charts from other repositories by specifying the repository URL with the --repo option.

For example, to download the Prometheus Operator chart from the Prometheus Helm repository, you would use the following command:

$ helm fetch prometheus-community/kube-prometheus-stack --version 14.0.0 --repo https://prometheus-community.github.io/helm-charts --untar=true --untardir=/tmp

This command downloads version 14.0.0 of the Prometheus Operator chart from the Prometheus Helm repository and saves it to the /tmp/kube-prometheus-stack directory.
