Kubernetes 1.1版支持Flocker。可以从PersistentVolume或直接从Pod卷引用Flocker数据集。

请确保你的kubernetes组件是v 1.1双重检查你的kubelet!
以下是使用Flocker集成的示例pod / rc规范
apiVersion: v1
kind: Service
metadata:
name: flocker-ghost
labels:
app: flocker-ghost
spec:
ports:
# the port that this service should serve on
- port: 80
targetPort: 80
selector:
app: flocker-ghost
---
apiVersion: v1
kind: ReplicationController
metadata:
name: flocker-ghost
# these labels can be applied automatically
# from the labels in the pod template if not set
labels:
purpose: demo
spec:
replicas: 1
template:
metadata:
labels:
app: flocker-ghost
spec:
containers:
- name: flocker-ghost
image: ghost:0.7.1
env:
- name: GET_HOSTS_FROM
value: dns
ports:
- containerPort: 2368
hostPort: 80
protocol: TCP
volumeMounts:
- name: ghost-data
mountPath: "/var/lib/ghost"
volumes:
- name: ghost-data
flocker:
datasetName: myuniqueflockerdatasetname
您需要通过flocker命令行工具提前创建卷。
$flockerctl create -m name=myuniqueflockerdatasetname -s 10G --node=583b0093
- node是运行时收到的flocker分配的节点ID(例如下面)-s is size
$ flockerctl list-nodes
