Deploy Jekyll App on Kubernetes

Question: Create a namespace jekyll-namespace-datacenter for jekyll.

PersistentVolume is already created on jump_host.

Create a PersistentVolumeClaim which should be named jekyll-site-datacenter under the same namespace. accessModes should be ReadWriteMany, request 1Gi storage.

Create a pod named jekyll-pod-datacenter for jekyll. Init container should be named as jekyll-init-datacenter, image should be kodekloud/jekyll, use command as [ "jekyll", "new", "/site" ]. Its image pull policy should be IfNotPresent, volumeMount name should be site and its mountPath should be /site. The main container should be named as jekyll-container-datacenter, its image should be kodekloud/jekyll-serve, volumeMount name should be site and its mountPath should be /site. Volume name should be site and persistent volume claim's claim name should be jekyll-site-datacenter

Create a service for jekyll which should be named jekyll-service-datacenter under the same namespace. Port should be 8080, protocol should be TCP, its targetPort should be 4000 and nodePort should be 31181. Its type should be NodePort and loadbalancer status should be {}.

You can use any labels as per your choice.

Please Note :-  Perform the below commands based on your question server,  user name & other details that might differ. So please read the task carefully before executing it. All the Best 👍

Solution:  

1. At first  kubectl  utility configure and working from jump server, run below commands  

thor@jump_host /$ kubectl get namespace NAME              STATUS   AGE default           Active   8m20s kube-node-lease   Active   8m21s kube-public       Active   8m22s kube-system       Active   8m22s thor@jump_host /$ thor@jump_host /$ kubectl get pods No resources found in default namespace. thor@jump_host /$

2. create a new namespace as per the task

thor@jump_host /$ kubectl create namespace jekyll-namespace-datacenter namespace/jekyll-namespace-datacenter created thor@jump_host /$ thor@jump_host /$ kubectl get namespace NAME                          STATUS   AGE default                       Active   118s jekyll-namespace-datacenter   Active   36s kube-node-lease               Active   2m kube-public                   Active   2m kube-system                   Active   2m thor@jump_host /$

 

3.  Create yaml  file with all the parameters , you can copy form gitlab

    https://gitlab.com/nb-tech-support/devops.git

    ( Refer Below Video for more clarity )

thor@jump_host /$ vi  /tmp/jekyll.yaml thor@jump_host /$ cat /tmp/jekyll.yaml apiVersion: v1 kind: PersistentVolumeClaim metadata:   name: jekyll-site-datacenter   namespace: jekyll-namespace-datacenter spec:   accessModes:     - ReadWriteMany   resources:     requests:       storage: 1Gi --- apiVersion: v1 kind: Service metadata:   name: jekyll-service-datacenter   namespace: jekyll-namespace-datacenter spec:   type: NodePort   selector:     app: jekyll-pod-datacenter   ports:     - port: 8080       protocol: TCP       targetPort: 4000       nodePort: 31181 status:   loadBalancer: {} --- apiVersion: v1 kind: Pod metadata:   name: jekyll-pod-datacenter   namespace: jekyll-namespace-datacenter   labels:     app: jekyll-pod-datacenter spec:   volumes:     - name: site       persistentVolumeClaim:         claimName: jekyll-site-datacenter   initContainers:     - name: jekyll-init-datacenter       image: kodekloud/jekyll       imagePullPolicy: IfNotPresent       command: ["jekyll", "new", "/site"]       volumeMounts:         - name: site           mountPath: /site   containers:     - name: jekyll-container-datacenter       image: kodekloud/jekyll-serve       volumeMounts:         - name: site           mountPath: /site thor@jump_host /$

4.  Run below command to create a pod 

thor@jump_host /$ kubectl create -f /tmp/jekyll.yaml persistentvolumeclaim/jekyll-site-datacenter created service/jekyll-service-datacenter created pod/jekyll-pod-datacenter created thor@jump_host /$

5.  Wait for  pods to get running status

       

thor@jump_host /$ kubectl get pods -n jekyll-namespace-datacenter NAME                    READY   STATUS    RESTARTS   AGE jekyll-pod-datacenter     1/1     Running   0          31s thor@jump_host /$

6.  Click on Finish & Confirm to complete the task successfully
