Helm CLI Usage

This page describes the CLI commands to fetch and publish charts after creating and configuring a Helm repository on Nexus.

Fetch Helm Charts

After adding a Nexus Helm repository to your Helm client, fetch the latest chart or a specific chart version using the following commands.

helm fetch <helm_repository_name>/<chart_name>
helm fetch <helm_repository_name>/<chart_name> --version <chart_version>

Where,

• <helm_repository_name> - Local alias of the repository added to the Helm client.
• <chart_name> - Name of the chart to fetch.
• <chart_version> The chart version to fetch.

Example:

helm fetch nexusrepo/mysql
helm fetch nexusrepo/mysql --version 1.4.0

Example using an NVIDIA Helm proxy:

helm repo add nvidia-helm https://example.repo/repository/nvidia-helm/ --username admin --password admin123

# Use with any Helm command - for example:
helm fetch nvidia-helm/gpu-operator --version 25.3.2

Upload Helm Charts

After creating a Helm hosted repository, publish charts to Nexus either through UI or using a supported command-line method. For publishing through UI, refer to Uploading Components.

Note
As of release 3.71.0, you can only upload components to a root Helm repository.

To upload a chart through command-line, use the following codeblock:

curl -u <username>:<password> http://<host>:<port>/repository/<repository_name>/ --upload-file <chart_file>.tgz -v

Where,

• <username> - Username used to authenticate to Nexus
• <password> -Password used to authenticate to Nexus
• <host> - Host name of your Nexus instance
• <port> - Port of your Nexus instance
• <repository_name> - Name of the Helm hosted repository
• <chart_file>.tgz - Chart package to upload

Example:

curl -u admin:admin http://localhost:8081/repository/helm-hosted/ --upload-file mysql-1.4.0.tgz -v

When using the Helm Push plugin, provide authentication credentials and a --context-path parameter that points to the hosted repository path, for example:

--username=<username> --password=<password> --context-path=/repository/<repository_name>/

Where,

• <username> - Username used to authenticate to Nexus
• <password> - Password used to authenticate to Nexus
• <repository_name> - Name of the Helm hosted repository

Example:

--username=admin --password=admin --context-path=/repository/helm-hosted/

Provenance files with the .prov.tgz extension use the same upload process as chart uploads and are stored at the same tree structure level as chart. More information about provenance files, visit the Helm website.
