探索 Azure Kubernetes 卷内容

Question

有什么方法可以连接到附加到 Kubernetes 集群的卷并探索其中的内容。

Answer 1

首先，创建一个 PersistentVolumeClaim 和 Pod 来挂载卷

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-claim
spec:
  accessModes:
    - ReadWriteOnce
  volumeName: <the-volume-that-you-want-to-explore>
  resources:
    requests:
      storage: 3Gi
---
apiVersion: v1
kind: Pod
metadata:
  name: volume-inspector
spec:
  containers:
    - name: foo
      command: ["sleep","infinity"]
      image: ubuntu:latest
      volumeMounts:
      - mountPath: "/tmp/mount"
        name: data
  volumes:
    - name: data
      persistentVolumeClaim:
        claimName: my-claim
        readOnly: true

然后 exec 进入 Pod 并开始探索

$ kubectl exec -it volume-inspector bash
root@volume-inspector:/# ls /tmp/mount
