怎么做网站缩略图seo简单优化
1.查找镜像
dockerhub访问不了的可以访问这个查找镜像 https://docker.aityp.com/
在docker服务器上拉取flink镜像到本地
拉取镜像到你的docker服务器本地
docker pull swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/apache/flink:2.0.0-scala_2.12-java17
将docker服务器本地的镜像打上标签
docker tag swr.cn-north-4.myhuaweicloud.com/ddn-k8s/docker.io/apache/flink:2.0.0-scala_2.12-java17 10.31.68.12:5000/flink:2.0.0-scala_2.12-java17
将打好标签的镜像推送到docker服务器
docker push 10.31.68.12:5000/flink:2.0.0-scala_2.12-java17
做完之后docker镜像如下，后面需要镜像的地方就写它
10.31.68.12:5000/flink:2.0.0-scala_2.12-java17
2.安装Flink Kubernetes Operator
官网：https://nightlies.apache.org/flink/flink-kubernetes-operator-docs-stable/docs/try-flink-kubernetes-operator/quick-start/
安装证书以启用webhook组件
kubectl create -f https://github.com/jetstack/cert-manager/releases/download/v1.8.2/cert-manager.yaml
如果yaml下载不成功，去 https://gitee.com/MiraculousWarmHeart/file-share/blob/master/flink/cert-manager.yaml复制，太长了就不贴这了，下到你的服务器上比如/data/flink/这个路径，执行
kubectl create -f /data/flink/cert-manager.yaml
部署稳定Flink Kubernetes Operator，依次执行
helm repo add flink-operator-repo https://downloads.apache.org/flink/flink-kubernetes-operator-1.11.0/
helm install flink-kubernetes-operator flink-operator-repo/flink-kubernetes-operator
装完验证
执行 kubectl get pods 结果如下
NAME READY STATUS RESTARTS AGE
flink-kubernetes-operator-5c8975f64b-jdgc6 2/2 Running 0 81m
执行 helm list 结果如下
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
flink-kubernetes-operator flink-prod 1 2025-05-28 15:08:00.683092663 +0800 CST deployed flink-kubernetes-operator-1.11.0 1.11.0
3.存储卷及NFS配置(非必须，有配置好的就不用做)
3.1. 创建存储类(StorageClass)
kubectl create -f flink-storage.yaml 也可以在kuboard上创建
apiVersion: v1
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:name: flink-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumer
3.2. 创建 PV（PersistentVolume）
定义 NFS 类型的 PV，指定存储容量和访问模式：
kubectl create -f flink-trans-pv.yaml 也可以在kuboard上创建
apiVersion: v1
kind: PersistentVolume
metadata:name: flink-trans-pvnamespace: flink-prod
spec:capacity:storage: 20Gi # 存储容量accessModes:- ReadWriteMany # 支持多节点读写storageClassName: nfs-flinknfs:server: 10.31.68.22 # NFS 服务器 IPpath: "/data/flink" # NFS 共享路径persistentVolumeReclaimPolicy: Retain # 回收策略（保留数据）
3.3. 创建 PVC（PersistentVolumeClaim）
申领符合要求的 PV 资源：
kubectl create -f flink-trans-pvc.yaml 也可以在kuboard上创建
apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: flink-trans-pvcnamespace: flink-prod
spec:accessModes:- ReadWriteManyresources:requests:storage: 5Gi # 实际申请的容量（需 ≤ PV 配置）storageClassName: nfs-flink
4.提交flink作业
4.1上传jar到nfs目录
scp ekrPatentDataProcessFlink-1.0.0.jar root@10.31.68.22:/flink/jobs/
或者本地直接上传到nfs目录
4.2 部署应用
kubectl create -f flink-kafka-trans.yaml
flink-kafka-trans.yaml内容如下
apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:name: flink-kafka-transnamespace: flink-prod
spec:image: 10.31.68.12:5000/flink:2.0.0-scala_2.12-java17flinkVersion: v2_0flinkConfiguration:taskmanager.numberOfTaskSlots: "2"serviceAccount: flinkpodTemplate:spec:hostAliases:- ip: "10.31.68.21"hostnames:- "k8smaster"containers:- name: flink-main-containervolumeMounts:- name: nfs-jar-volume # 挂载 Jar 包存储mountPath: /data/flinkresources:requests:memory: "2048Mi"cpu: "1000m"limits:memory: "2048Mi"cpu: "1000m"volumes:- name: nfs-jar-volume # 关联 PVCpersistentVolumeClaim:claimName: flink-trans-pvc # 替换为你的 PVC 名称jobManager:resource:memory: "2048m"cpu: 1taskManager:resource:memory: "2048m"cpu: 1job:jarURI: local:///data/flink/jobs/ekrPatentDataProcessFlink-1.0.0.jar # 容器内挂载路径entryClass: net.cnki.ekr.transfer.EkrFlinkTransApplicationargs: []parallelism: 2upgradeMode: stateless4.3 查看日志
kubectl logs -f deploy/flink-kafka-trans
5.转发暴露端口(非必须，日志载k8s容器中可以看)
指定映射端口
kubectl port-forward deployment/flink-kafka-trans 28081:8081
不指定映射端口，由kubectl来选择和分配本地端口
kubectl port-forward deployment/flink-kafka-trans :8081
或者kubectl port-forward service/flink-kafka-trans 28081:8081
访问http://10.31.68.21:28081
6.要停止作业并删除FlinkDeployment
kubectl delete flinkdeployment/flink-kafka-trans
