Non-high availability setup

StackState Self-hosted v5.1.x

Overview

The recommended Kubernetes/OpenShift deployment of StackState is a production ready setup with many services running redundantly. If required, it's also possible to run StackState in a non-redundant setup, where each service has only a single replica.

The non-high availability setup is only suitable for situations that don't require high availability.

Create nonha_values.yaml

To deploy StackState in a non-high availability setup, you will need a nonha_values.yaml file. Follow the instructions below to create this file and use it for deployment of StackState.

  1. Create a Helm values file nonha_values.yaml with the following content and store it next to the generated values.yaml file:

     # This files defines additional Helm values to run StackState on a 
     # non-high availability production setup. Use this file in combination
     # with a regular values.yaml file that contains your API key, etc.
