Deploy pods on Kubernetes Cluster in localhost

#kubernetes #beginners #tutorial #minikube

Pre-requisites:

Below are essentials before you start deploying containers into kubernetes cluster

Verify Docker & Minikube installed correctly:

To verify docker type "docker" in powershell and see if you get below options.PS C:\WINDOWS\system32> docker

PS C:\WINDOWS\system32> dockerUsage:  docker [OPTIONS] COMMANDA self-sufficient runtime for containersOptions:      --config string      Location of client config files (default                           "C:\\Users\\Jasper\\.docker")  -c, --context string     Name of the context to use to connect to the                           daemon (overrides DOCKER_HOST env var and                           default context set with "docker context use")

To verify Minikube, type "minikube" in powershell and see if you get below options.PS C:\WINDOWS\system32> minikube

PS C:\WINDOWS\system32> minikubeminikube provisions and manages local Kubernetes clusters optimized for development workflows.Basic Commands:  start            Starts a local Kubernetes cluster  status           Gets the status of a local Kubernetes cluster  stop             Stops a running local Kubernetes cluster  delete           Deletes a local Kubernetes cluster

Step 1: Create Kubernetes cluster

1.create Mikikubecluster on VirtualBox VM

minikube start --driver=virtualbox

2.Get cluster information

PS C:\WINDOWS\system32> kubectl cluster-infoKubernetes control plane is running at https://192.168.XX.XXX:8443CoreDNS is running at https://192.168.XX.XXX:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxyTo further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

3.get nodes

PS C:\WINDOWS\system32> kubectl get nodesNAME       STATUS   ROLES           AGE   VERSIONminikube   Ready    control-plane   13m   v1.27.4

4.get namespaces

PS C:\WINDOWS\system32> kubectl get namespacesNAME              STATUS   AGEdefault           Active   14mkube-node-lease   Active   14mkube-public       Active   14mkube-system       Active   14m

5.get All pods

PS C:\WINDOWS\system32> kubectl get pods -ANAMESPACE     NAME                               READY   STATUS    RESTARTS      AGEkube-system   coredns-5d78c9869d-df2qj           1/1     Running   0             14mkube-system   etcd-minikube                      1/1     Running   0             14mkube-system   kube-apiserver-minikube            1/1     Running   0             14mkube-system   kube-controller-manager-minikube   1/1     Running   0             14mkube-system   kube-proxy-8zw65                   1/1     Running   0             14mkube-system   kube-scheduler-minikube            1/1     Running   0             14mkube-system   storage-provisioner                1/1     Running   1 (13m ago)   14m
