前置条件:nfs已准备就绪,参考:K8S通过NFS实现共享存储
1、定义grafana-pv.yml
apiVersion: v1
kind: PersistentVolume
metadata:
name: grafana-pv
labels:
pv: grafana-pv
spec:
capacity:
storage: 2Gi
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Recycle
storageClassName: nfs
nfs:
path: /data/k8s/grafana-pv
server: 192.168.1.20
2、创建 grafana.yml
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: grafana-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: nfs
selector:
matchLabels:
pv: grafana-pv
---
apiVersion: apps/v1
kind: Deployment
metadata:
labels:
app: grafana
name: grafana
spec:
selector:
matchLabels:
app: grafana
template:
metadata:
labels:
app: grafana
spec:
securityContext:
fsGroup: 472
supplementalGroups:
- 0
containers:
- name: grafana
image: grafana/grafana:latest
imagePullPolicy: IfNotPresent
ports:
- containerPort: 3000
name: http-grafana
protocol: TCP
readinessProbe:
failureThreshold: 3
httpGet:
path: /robots.txt
port: 3000
scheme: HTTP
initialDelaySeconds: 10
periodSeconds: 30
successThreshold: 1
timeoutSeconds: 2
livenessProbe:
failureThreshold: 3
initialDelaySeconds: 30
periodSeconds: 10
successThreshold: 1
tcpSocket:
port: 3000
timeoutSeconds: 1
resources:
requests:
cpu: 250m
memory: 750Mi
volumeMounts:
- mountPath: /var/lib/grafana
name: grafana-pv
volumes:
- name: grafana-pv
persistentVolumeClaim:
claimName: grafana-pvc
---
apiVersion: v1
kind: Service
metadata:
name: grafana
spec:
ports:
- port: 3000
protocol: TCP
targetPort: http-grafana
selector:
app: grafana
sessionAffinity: None
type: LoadBalancer
3、拷贝grafana-pv.yml 和 grafana.yml 到master节点
4、执行以下命令
#kubectl apply -f grafana-pv.yml
#kubectl apply -f grafana.yml
5、检查服务状态
[root@bigdata02 soft]# kubectl get service
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
grafana LoadBalancer 10.109.168.172 <pending> 3000:30989/TCP 48m
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 5h27m
[root@bigdata02 soft]# kubectl get pod
NAME READY STATUS RESTARTS AGE
grafana-5f986967b4-g8ksf 1/1 Running 0 19m
[root@bigdata02 soft]#
