This document covers deployment process for GoRules BRMS on Kubernetes.

Requirements

To begin, install Helm on your computer and connect to your cluster.

• Helm 3 (>=3.8)
• Kubernetes (1.2x+)
  • Nodes - linux OS and x86_64 architecture
  • Minimum 1GB RAM and 0.5 vCPU
• Postgres DB
• License Key obtained from https://portal.gorules.io

Configure

1. Download values.yaml https://artifacthub.io/packages/helm/gorules/gorules-brms?modal=values.
2. Rename file to my-values.yaml.
3. Replace variables such as appUrl and licenseKey with your values
4. Fill in the Postgres connection details

Installation

After configuring my-values.yaml file you can install GoRules BRMS by running:

helm install my-gorules-brms oci://registry-1.docker.io/gorulescharts/gorules-brms -f my-values.yaml

📘

You can also install specific version by adding --version 1.6.0 before -f my-values.yaml.

📘

For operational environments we strongly suggest setting up ingress/

Test installation

For testing purposes you can forward the port for testing:

kubectl port-forward services/my-gorules-brms 4200:80

BRMS will be available on http://localhost:4200. In the real environment, you should also set ingress on a proper URL.

Upgrade

You can upgrade version by running:

helm upgrade my-gorules-brms oci://registry-1.docker.io/gorulescharts/gorules-brms --version x.x.x -f my-values.yaml

📘

Replace --version x.x.x with actual number such as --version 1.6.0

FAQ

Multi architecture node pools

If you are running multi architecture node pools you can force Linux OS and x86_64 architecture by modifying nodeSelector inside my-values.yaml file to:

nodeSelector:
  kubernetes.io/arch: amd64
  kubernetes.io/os: linux

Next, perform helm upgrade....
