Helm Package Manager

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>`__.
A Helm v3 client is installed on controllers for local use by admins to manage

helm charts of optional StarlingX applications, such as Openstack. The admin

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

For non-admin users \(i.e. users without access to the default Tiller
server running in kube-system namespace\), you must create a Tiller server
for this specific user in a namespace that they have access to.
Helm v3 is recommended for users to install and manage their
containerized applications. However, Helm v2 may be required, for example, if
the containerized application supports only a Helm v2 helm chart.
.. rubric:: |context|
By default, helm communicates with the default Tiller server in the
kube-system namespace. This is not accessible by non-admin users.
For non-admin users use of the helm client, you must create your own Tiller
server, in a namespace that you have access to, with the required |RBAC|
Helm v2 is only supported remotely. Also, it is only supported with kubectl and
Helm v2 clients configured directly on the remote host workstation. In
addition to installing the Helm v2 clients, users must also create their own
Tiller server, in a namespace that the user has access, with the required |RBAC|
capabilities and optionally |TLS| protection.
To create a Tiller server with |RBAC| permissions within the default
namespace, complete the following steps on the controller: Except where
indicated, these commands can be run by the non-admin user, locally or
remotely.
