Although StackStorm can be distributed as a Red Hat Package Manager/Debian (RPM/Deb) for Linux systems and as Docker images, if you plan to run business-critical automation tasks, it is recommended to deploy StackStorm High Availability (HA) cluster on Kubernetes.

In this recipe, we will learn how to deploy StackStorm on Kubernetes by following these steps:

1. Add the Helm repository to your list of local charts:

$ helm repo add stackstorm https://helm.stackstorm.com/

2. Install the StackStorm HA cluster using the Helm chart. The following command will deploy StackStorm and its dependencies, such as MongoDB and RabbitMQ:

$ helm install stackstorm/stackstorm-ha --name=st2 --namespace=stackstorm

3. The installation process may take 2 to 3 minutes. Confirm that the release has been deployed and running:

$ helm ls st2
NAME REVISION  UPDATED                  STATUS   CHART                APP VERSION NAMESPACE
st2  1         Wed Oct 30 23:06:34 2019 DEPLOYED stackstorm-ha-0.22.0 3.2dev      stackstorm

Now, you have StackStorm running in our cluster. Next, we will access the UI or use the CLI to interact with StackStorm.
