2. Check that all is ok by running the following commands:

# show current context
kubectl config current-context

# get all contexts
kubectl config get-contexts

#  change to local context
kubectl config use-context docker-desktop

# change to EKS context
kubectl config use-context arn:aws:eks:eu-west-2:${AWS_ACCOUNT}:cluster/java-cro-cluster

kubectl cluster-info
kubectl get nodes
kubectl get namespaces
# pod & others
kubectl get pods
kubectl describe pod hoodie-db-xx
kubectl describe service hoodie-db-xx
kubectl get services
kubectl get svc hoodie-db -o wide

Set Up the Kubernetes Dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml

Enable access to the Dashboard:

kubectl proxy

Access here

kubectl apply -f dashboard-user.yaml
kubectl apply -f dashboard-role.yaml

These are a few simple Kubernetes instructions for running a cluster locally on Docker.

Each directory in the main project contains more resources, including the demo steps.
