Prerequisites
kubectlSet your kubeconfig so you can access the workload cluster.
If you followed the steps in the linked article above, you should hopefully have the environment variable $WORKLOAD_CLUSTER_NAME already set, and its kubeconfig file is located in $HOME/$WORKLOAD_CLUSTER_NAME/kubeconfig.
This step assumes you followed Cluster API Workload Cluster (vSphere).
#Replace the value to match the name of your workload cluster
export WORKLOAD_CLUSTER_NAME="wlc01"
export KUBECONFIG="$HOME/$WORKLOAD_CLUSTER_NAME/kubeconfig"Create a development namespace
kubectl create namespace developmentCreate a simple deployment. The below will create a YAML file in the $HOME/Development directory.
mkdir -p $HOME/Development
tee $HOME/Development/my-nginx-deployment.yaml >/dev/null <<EOF
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-nginx-deployment
labels:
app: nginx

EOFApply the Deployment, this will deploy nginx with the deployment name my-nginx-deployment.
kubectl apply -f "$HOME/Development/my-nginx-deployment.yaml" --namespace developmentCheck to see if our Deployment has been created. You should hopefully see all Pods READY and Running
kubectl get deployment -n development
kubectl get pod -n developmentAlternative imperative commands to create the same deployment, with a slightly different name.
kubectl create deployment my-nginx-deployment2 --image=nginx:1.14.2 --namespace=development
