I am trying to use Kubernetes volumes for Nginx, but am facing an issue with it. After volumes are set Nginx is unable to serve the HTML page. Also am tried with PV and PVS this time also got the same error.

nginx.yml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels: 
    app: nginx 

spec: 
  replicas: 2
  selector: 
    matchLabels: 
      app: nginx
  template:
    metadata: 
      labels:
        app: nginx
    spec: 
      volumes:
        - name: nginxhtml
          # persistentVolumeClaim: 
          #   claimName: pvc
          hostPath:
            path: /home/amjed/Documents/SPS/k8s/mongo/mnt
      containers:
        - name: nginx
          image: nginx
          volumeMounts:
            - name: nginxhtml 
              mountPath: /usr/share/nginx/html
              
          ports: 
            - containerPort: 80

apiVersion: v1
kind: Service
metadata:
  name: nginx-service

    app: nginx

  ports:
    - protocol: TCP
      port: 80
      targetPort: 80

1. reduce the replica count to 1
2. verify that /home/amjed/Documents/SPS/k8s/mongo/mnt location is valid and is accessible from the pod

CodePudding user response：

First, create folder that you want to mount inside minikube:

minikube ssh

mkdir /home/docker/some-mount

Make sure that you have some .html file inside that folder, otherwise you will get 403 error. You also need to add securityContext fsGroup inside your Deployment manifest, so that /usr/share/nginx/html is owned by nginx user (101 uid).

Snippet for your Deployment below:

spec:
  replicas: 2
  selector: 
    matchLabels: 
      app: nginx
  template:
    metadata: 
      labels:
        app: nginx
    spec:
      securityContext:
        fsGroup: 101
      volumes:
        - name: nginxhtml
          hostPath:
            path: /home/docker/nginx-mount
      containers:
        - name: nginx
          image: nginx
          volumeMounts:
            - name: nginxhtml 
              mountPath: /usr/share/nginx/html       
          ports: 
            - containerPort: 80

Let me know if it works.
