在Kubernetes中部署Zookeeper集群通常涉及以下步驟:
apiVersion: v1
kind: ConfigMap
metadata:
name: my-zookeeper-config
data:
zoo.cfg: |
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data
clientPort=2181
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: my-zookeeper
spec:
replicas: 3
serviceName: my-zookeeper
selector:
matchLabels:
app: my-zookeeper
template:
metadata:
labels:
app: my-zookeeper
spec:
containers:
- name: zookeeper
image: zookeeper:3.6.2
ports:
- containerPort: 2181
volumeMounts:
- name: data
mountPath: /data
env:
- name: ZOO_MY_ID
valueFrom:
fieldRef:
fieldPath: metadata.name
- name: ZOO_SERVERS
value: server.1=my-zookeeper-0.my-zookeeper.default.svc.cluster.local:2888:3888;2181 server.2=my-zookeeper-1.my-zookeeper.default.svc.cluster.local:2888:3888;2181 server.3=my-zookeeper-2.my-zookeeper.default.svc.cluster.local:2888:3888;2181
volumeClaimTemplates:
- metadata:
name: data
spec:
accessModes: [ "ReadWriteOnce" ]
resources:
requests:
storage: 1Gi
apiVersion: v1
kind: Service
metadata:
name: my-zookeeper
spec:
clusterIP: None
selector:
app: my-zookeeper
ports:
- port: 2181
targetPort: 2181
kubectl apply -f my-zookeeper-config.yaml
kubectl apply -f my-zookeeper-statefulset.yaml
kubectl apply -f my-zookeeper-service.yaml
以上步驟將在Kubernetes中部署一個包含3個Zookeeper節點的集群,可以根據實際需求調整副本數和存儲大小等參數。
