k8s /etc/kubernetes目录下的文件 k8s挂载本地目录

1.挂载本地路径

pod yaml

apiVersion: v1
kind: Pod
metadata:
  name: test
spec:
  containers:
  - name: test
    image: library/busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo hello; sleep 10;done"]
    volumeMounts:
    - mountPath: /mnt/host_src  # 容器内挂载路径,会自动创建
      name: local-vol
  volumes:
  - name: local-vol # 与volumeMounts对应
    hostPath:
      path: /tmp # 宿主机路径

2.pod直接挂载nfs

2.1 配置nfs

linux之nfs配置

2.2 pod直接挂载nfs

pod yaml

apiVersion: v1
kind: Pod
metadata:
  name: test-nfs
spec:
  containers:
  - name: test-nfs
    image: library/busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo hello; sleep 10;done"]
    volumeMounts:
    - mountPath: /mnt/data  # 容器内挂载路径
      name: nfs-vol
  volumes:
  - name: nfs-vol
    nfs:
      server: 192.168.185.6
      path: /data

3.pvc挂载nfs

pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv3
spec:
  capacity:
    storage: 5Gi
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Recycle
  storageClassName: slow
  mountOptions:
    - nolock
    - nfsvers=3
    - vers=3
  nfs:
    path: /data
    server: 192.168.0.101

kubectl apply -f pv.yaml
kubectl get pv

pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: task-pv-claim
spec:
  storageClassName: slow
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi

kubectl apply -f pvc.yaml
kubectl get pvc

pvc-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: task-pv-pod
spec:
  volumes:
    - name: task-pv-storage
      persistentVolumeClaim:
        claimName: task-pv-claim
  containers:
    - name: task-pv-container
      image: nginx
      ports:
        - containerPort: 80
          hostPort: 8008
          name: "http-server"
      volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: task-pv-storage

kubectl apply -f pvc-pod.yaml
kubectl get pod

4.挂载本地pvc

pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: task-pv-volume
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/data"

kubectl apply -f pv.yaml
kubectl get pv

pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: task-pv-claim
spec:
  storageClassName: slow
  volumeMode: Filesystem
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi

kubectl apply -f pvc.yaml
kubectl get pvc

pvc-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: task-pv-pod
spec:
  volumes:
    - name: task-pv-storage
      persistentVolumeClaim:
        claimName: task-pv-claim
  containers:
    - name: task-pv-container
      image: nginx
      ports:
        - containerPort: 80
          hostPort: 8008
          name: "http-server"
      volumeMounts:
        - mountPath: "/usr/share/nginx/html"
          name: task-pv-storage

kubectl apply -f pvc-pod.yaml
kubectl get pod
