Welcome to the Cloudsmith Documentation Hub. You'll find comprehensive guides and documentation to help you start working with Cloudsmith as quickly as possible, as well as support if you get stuck. Let's jump right in!

Helm Chart Repository

Cloudsmith provides public & private repositories for Helm Charts

Helm is a package manager for Kubernetes that allows development and operations teams to easily manage and deploy these increasingly complex cloud native applications to their Kubernetes clusters. Helm allows you to manage applications on your Kubernetes cluster in much the same way as you’d manage applications on your Linux server with apt or yum.

Helm works by packaging up a set of YAML definitions along with the necessary configuration to quickly stand up all components of an application in a repeatable way. A single chart can be as simple or complex as necessary, deploying anything from a single container to a full distributed application. Helm combines these application definitions with user-provided configuration to allow simple overriding of configuration where needed, allowing users to concentrate on shipping software and not on the nitty-gritty of configuring every application they need to run.

Helm packages are known as “Charts” and are stored in a “Chart Repository”. By default, Helm comes bundled with the “stable” chart repository, hosted for free by Google. Most public charts are hosted here, mostly provided by vendors packaging their own software for use by others.

For more information on Helm, please see:

Contextual Documentation

The examples in this document are generic. Cloudsmith provides contextual setup instructions within each repository, complete with copy n' paste snippets (with your namespace/repo/rsa-key pre-configured).

In the following examples:




Your Cloudsmith account name or organisation name (namespace)


Your Cloudsmith Repository name (also called "slug")


Your Cloudsmith Entitlement Token (see Entitlements for more details)


Your Cloudsmith username


Your Cloudsmith password


Your Cloudsmith API Key


A name for your repository in your helm configuration


The name of your chart


The version number of your chart

Upload a Chart

To upload, you will need to generate your chart first. You can do this with the helm CLI:

helm package .

This generates a chart package file (.tgz) like CHART_NAME-CHART_VERSION.tgz that you can upload.


Please see the official Chart development guide for more information on building your own Charts for distribution.

Upload via the Cloudsmith CLI

For full details of how to install and setup the Cloudsmith CLI, see Command Line Interface.

The command to upload a Helm chart via the Cloudsmith CLI is:



cloudsmith push helm org/repo your-chart-1.0.0.tgz

Upload via Cloudsmith Website

Please see Upload a Package for details of how to upload via the Website UI.

Example Project

For examples of what your project should look like for packaging and publishing/uploading, please have a look at our examples repository (on GitHub). We'll supplement these with more detailed guidance later but otherwise, just ask! - we're here to help.

Download / Install a Chart


Assuming you have helm already installed, it is straight-forward to add a Cloudsmith-based chart repository. You use the helm repo add and helm repo update commands as follows:

Public Repositories

helm repo add NAME \
helm repo update

Private Repositories


Private Cloudsmith repositories require authentication. You can choose between two types of authentication, Entitlement Token Authentication or HTTP Basic Authentication.

The setup method will differ depending on what authentication type you choose to use.


Entitlement Tokens, User Credentials and API-Keys should be treated as secrets, and you should ensure that you do not commit them in configurations files along with source code or expose them in any logs

helm repo add NAME \
helm repo update
helm repo add NAME \
  ''  \
  --username USERNAME \
  --password PASSWORD
helm repo update
helm repo add NAME \
  ''  \
  --username USERNAME \
  --password API-KEY
helm repo update
helm repo add NAME \
  ''  \
  --username token \
  --password TOKEN
helm repo update

Installing a Chart

To install/use a specific version of a chart:

helm install NAME/CHART_NAME --version CHART_VERSION

To install the latest version of a chart:

helm install NAME/CHART_NAME

Or you can upgrade to the most recent version of a chart if you've already installed:

helm upgrade NAME/CHART_NAME

If you've got a requirements.yaml file in your chart, you can specify this as a dependency:

  - name: CHART_NAME
    version: CHART_VERSION
    repository: NAME

Removing Setup

Helm provides a very clean method of removing a chart repository, simply run the following command:

helm repo remove NAME
