Step-05: Configure kubeconfig for kubectl for Docker Desktop k8s Cluster

# Verify if kubectl installed (Docker desktop should install kubectl automatically)
which kubectl

# Verify kubectl version
kubectl version 
kubectl version --short
kubectl version --client --output=yaml

# List Config Contexts
kubectl config get-contexts

# Config Current Context

deployment.yaml
service.yaml

# Deploy k8s Resources to Docker Desktop k8s Cluster
kubectl apply -f kube-manifests/

# List k8s Deployments
kubectl get deploy

# List k8s pods
kubectl get pods

# List k8s Services
kubectl get svc

# Access Application
http://localhost:31300
or
http://127.0.0.1:31300

# Uninstall k8s Resources from Docker Desktop k8s cluster
kubectl delete -f kube-manifests/

# List pods, svc, deploy
kubectl get pods
kubectl get svc
kubectl get deploy

Step-07: Install Helm using Package Managers

# MacOS
brew install helm

# From Chocolatey (Windows)
choco install kubernetes-helm

# Download MacOS Apple Silicon (Update kubectl version)
curl -LO "https://dl.k8s.io/release/v1.27.2/bin/darwin/arm64/kubectl"

# Make Binary executable

# Move the kubectl binary to a file location on your system PATH.
sudo mv ./kubectl /usr/local/bin/kubectl
ls -lrta /usr/local/bin/kubectl

# Verify kubectl version

kubectl version --short
kubectl version --client --output=yaml
