在Kubernetes中部署MySQL集群可以使用StatefulSet和PersistentVolume。以下是一個簡單的步驟:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mysql-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
apiVersion: apps/v1
kind: StatefulSet
metadata:
name: mysql
spec:
serviceName: mysql
replicas: 3
selector:
matchLabels:
app: mysql
template:
metadata:
labels:
app: mysql
spec:
containers:
- name: mysql
image: mysql:latest
env:
- name: MYSQL_ROOT_PASSWORD
value: password
ports:
- containerPort: 3306
volumeMounts:
- name: mysql-persistent-storage
mountPath: /var/lib/mysql
volumeClaimTemplates:
- metadata:
name: mysql-persistent-storage
spec:
accessModes: [ "ReadWriteOnce" ]
resources:
requests:
storage: 1Gi
kubectl apply -f mysql-pvc.yaml
kubectl apply -f mysql-statefulset.yaml
以上步驟將會在Kubernetes中部署一個具有3個MySQL實例的集群,并且每個實例都有1Gi的PersistentVolume用于存儲數據。在實際生產環境中,還需要考慮數據的備份和恢復、監控和故障恢復等相關問題。
