Tillerless Astronomer on Openshift

Local dev setup

Install helm on your local machine, we will use it to generate YAML.

Tiller won't be installed on the cluster.

You'll be using the CLI only to generate YAML from a YAML template.

If you'd prefer to not fully avoid helm, you can hand-craft YAML or write your own generator scripts.

• NetworkPolicy
• Secret
• Role
• RoleBinding
• ClusterRole
• ClusterRoleBinding
