Multi-Cluster Setup

In this tutorial we create the following Multi-Cluster environment using primazactl

Prerequisites

• kind
• primazactl

Tutorial

1. Create the Main Cluster

   kind create cluster --name main
   

2. Install the Cert-Manager on Main Cluster

   kubectl apply \
       -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.0/cert-manager.yaml \
       --kubeconfig <(kind get kubeconfig --name main)
   kubectl rollout status -n cert-manager deploy/cert-manager-webhook -w --timeout=120s \
       --kubeconfig <(kind get kubeconfig --name main)
   

3. Create the Worker Cluster

   kind create cluster --name worker
   

4. Install the Cert-Manager on Worker Cluster

   kubectl apply \
       -f https://github.com/cert-manager/cert-manager/releases/download/v1.12.0/cert-manager.yaml \
       --kubeconfig <(kind get kubeconfig --name worker)
   kubectl rollout status -n cert-manager deploy/cert-manager-webhook -w --timeout=120s \
       --kubeconfig <(kind get kubeconfig --name worker)
   

5. Create a Primaza Tenant

   primazactl create tenant primaza-mytenant \
       --version latest \
       --context kind-main
   

6. Join the Worker cluster

   primazactl join cluster \
       --version latest \
       --tenant primaza-mytenant \
       --cluster-environment worker \
       --environment demo \
       --context kind-worker \
       --tenant-context kind-main
   

7. Create an Application Namespace named "applications" in the Worker Cluster

   primazactl create application-namespace applications \
       --version latest \
       --tenant primaza-mytenant \
       --cluster-environment worker \
       --context kind-worker \
       --tenant-context kind-main
   

8. Create a Service Namespace named "services" in the Worker Cluster

   primazactl create service-namespace services \
       --version latest \
       --tenant primaza-mytenant \
       --cluster-environment worker \
       --context kind-worker \
       --tenant-context kind-main
