Recently understand this k8s in PVC storage here stuck for two days, today finally considered probably understand what is going on.

The following is a summary of the process.

• Create a PersistentVolume backed by physical storage. you will not associate the volume with any Pod.

• Create a PersistentVolumeClaim that will be automatically bound to the appropriate PersistentVolume.

• Create a deployment that uses a PersistentVolumeClaim as storage.

Schematic

Explanation

Steps

Mirror pulling

• Here we use WIZ as a test, you can refer to the For Knowledge Notes docker privatization deployment

docker pull wiznote/wizserver

minikube mount local directory

• Start the mount

minikube start --mount --mount-string="/mnt/data:/app/wiz"

• Verify

minikube ssh
cd /app/wiz
# Just create a file and go to /mnt/data on the host to see if it exists

PV creation

• configuration file “ wiz-pv.yaml
  “`.

apiVersion: v1
type. persistentVolume
Metadata.
  name: wiz-pv-volume
  tag.
    type: local
specification.
  storageClassName: manual
  capacity.
    Storage. 10Gi
  Access mode.
    - One-time read/write
  hostPath:
    Path." /app/wiz"

• Deploy

kubectl create -f wiz-pv.yaml

• View

kubectl get pv

• Delete

kubectl delete pv wiz-pv-volume

PVC creation

• Configuration file wiz-pvc.yaml.

apiVersion: v1
type. persistentVolumeClaim
Metadata.
  name: wiz-pv-claim
specification.
  storageClassName: manual
  accessModes:
    - ReadWriteOnce
  resource.
    Request.
      Storage. 3Gi

• Deployment

kubectl create -f wiz-pvc.yaml

• View

kubectl get pvc

• Delete

kubectl delete pvc wiz-pv-claim

Deployment creation

• configuration file wiz.yaml.

• Deployment

kubectl create -f wiz.yaml

Create the service

• Configuration file wiz-service.yaml.

apiVersion: v1
type: service
metadata:
  name: wiz-service
spec:
  type: node port
  selector.
    application: wiz
  ports:
  - Protocol: TCP
    port. 8888
    Target port: 80

• Deploy

kubectl create -f wiz-service.yaml
