====================
Helm Package Manager
====================

|prod-long| supports Helm with Tiller, the Kubernetes package manager that can
be used to manage the lifecycle of applications within the Kubernetes cluster.

.. rubric:: |context|

Helm packages are defined by Helm charts with container information sufficient
for managing a Kubernetes application. You can configure, install, and upgrade
your Kubernetes applications using Helm charts. Helm charts are defined with a
default set of values that describe the behavior of the service installed
within the Kubernetes cluster.

Upon system installation, the official curated helm chart repository is added
to the local helm repo list, in addition, a number of local repositories
\(containing optional |prod-long| packages\) are created and added to the helm
repo list. For more information, see `https://github.com/helm/charts
<https://github.com/helm/charts>`__.

Use the following command to list the helm repositories:

.. code-block:: none

    ~(keystone_admin)$ helm repo list
    NAME            URL
    stable          https://kubernetes-charts.storage.googleapis.com
    local           http://127.0.0.1:8879/charts
    starlingx       http://127.0.0.1:8080/helm_charts/starlingx
    stx-platform    http://127.0.0.1:8080/helm_charts/stx-platform

For more information on Helm, see the documentation at `https://helm.sh/docs/
<https://helm.sh/docs/>`__.

**Tiller** is a component of Helm. Tiller interacts directly with the
Kubernetes API server to install, upgrade, query, and remove Kubernetes
resources.
