Install Minikube And Spin Up A Minikube Cluster

• You can set up a local Kubernetes cluster.
• Start minikube with:

  minikube start 
  

• The minikube command creates a cluster from scratch.
• The kubectl allows you to interact with your cluster.
• GCP, Azure, AWS etc use their own command syntax to spin up a Kubernetes cluster. Then afterwards we use kubectl.
• To get information about your Kubernetes cluster, we run

  kubectl cluster-info
  

  • Will see where CoreDNS is running (this is the container network interface).
• If you see an error message saying the connection to the cluster was refused, it means you do not have minikube running.
• To get information on the nodes, we then run:

  kubectl get nodes
  

• To get the namespaces that are created by default, we run:

  kubectl get namespaces
  

• namespaces are a good way to isolate and manage applications.
• To list all available pods, we run:

  kubectl get pods -A
  

• The -A flag hows the pods in every namespace.
• Pods are how containers are run in Kubernetes.
• Pods are also the software to run a Kubernetes cluster itself.
• To see all of the running services, we do:

  kubectl get services -A
  

• Services act as loadbalancers within the cluster. They direct traffic to pods.
