Prepare a Local Kubernetes Environment

The following tutorial uses kind to prepare/set up a local Kubernetes environment for a local ESS standalone deployment on Linux.

1. Start Docker if it is not already running. The below steps have been tested with Docker CPU setting of 6.

2. Open a Terminal window.

3. Install kind.

4. Optional. Create a directory for your kind configuration and go to that directory.

5. Create a kind-config.yaml file:

    cat < kind-config.yaml
    kind: Cluster
    apiVersion: kind.x-k8s.io/v1alpha4
    name: my-local-kind
    nodes:
    - role: control-plane
      kubeadmConfigPatches:
      - |
        kind: InitConfiguration
        nodeRegistration:
          kubeletExtraArgs:
            node-labels: "ingress-ready=true"
      extraPortMappings:
      - containerPort: 80
        hostPort: 80
        protocol: TCP
      - containerPort: 443
        hostPort: 443
        protocol: TCP
    EOF

   This example configuration specifies the cluster name of my-local-kind . You can specify a different name for the cluster.

6. Create a cluster, specifying your kind-config.yaml file:

   kind create cluster --config=kind-config.yaml

7. Enable Certificate management controller :

kubectl apply -f https://github.com/jetstack/cert-manager/releases/2.3/download/cert-manager.yaml

8. Wait for successful setup and rollout of the cert manager and ingress controller.

kubectl -n cert-manager wait --for condition=established --timeout=60s customresourcedefinition.apiextensions.k8s.io/certificates.cert-manager.io
kubectl -n cert-manager rollout status deployment/cert-manager-webhook
kubectl -n ingress-nginx rollout status deployment/ingress-nginx-controller

Upon successful completion, this local Kubernetes environment can be used for a standalone ESS deployment . See Installation for details.
