• k8s 相关


    • 阿里 dns
    223.5.5.5
    

      

     

    •  kubectl get pods -n kube-system

    •  测试 kubernetes 集群
    在 Kubernetes 集群中创建一个 pod,验证是否正常运行:
    $ kubectl create deployment nginx --image=nginx
    $ kubectl expose deployment nginx --port=80 --type=NodePort
    $ kubectl get pod,svc

    访问地址:http://NodeIP:Port

    • kubectl 工具查看当前集群组件状态
    kubectl get cs

    • Error from server (Forbidden): Forbidden (user=kubernetes, verb=get, resource=nodes, subresource=proxy) ( pods/log java-k8sdemo-68647fdfd7-pwnnj)
    [root@m1 ~]# kubectl create clusterrolebinding kubernetes   --clusterrole=cluster-admin   --user=kubernetes

    •  两种安装方式比较

     

    • yaml 文件中,controller & pod

     

    • 容器交付过程

      

    • 制作镜像
    docker build -t xxl-job-executor-sample-springboot:2.2.0 .

    • 查看镜像是否制作成功

    • 将镜像推送到镜像仓库
    $ sudo docker login --username=xil**** registry.cn-shanghai.aliyuncs.com
    $ sudo docker tag [ImageId] registry.cn-shanghai.aliyuncs.com/java-k8sdemo/xxl-job-executor:[镜像版本号]
    $ sudo docker push registry.cn-shanghai.aliyuncs.com/java-k8sdemo/xxl-job-executor:[镜像版本号]
    • 从阿里云下载镜像部署到本地 k8s:
    1. kubectl create deployment xxl-job-admin --image=registry.cn-shanghai.aliyuncs.com/java-k8sdemo/xxl-job-admin:2.2.0 --dry-run -o yaml > xxl-job-admin-deployment.yaml
    kubectl create deployment xxl-job-executor --image=registry.cn-shanghai.aliyuncs.com/java-k8sdemo/xxl-job-executor-sample-springboot:2.2.0 --dry-run -o yaml > xxl-job-executor-deployment.yaml

    2. kubectl apply -f xxl-job-admin-deployment.yaml 
    kubectl apply -f xxl-job-executor-deployment.yaml 

    3. kubectl expose deployment xxl-job-admin --port=8080 --target-port=8080 --type=NodePort --dry-run=client -o yaml > xxl-job-admin-svc-expose.yaml
    kubectl expose deployment xxl-job-executor --port=7001 --target-port=7001 --type=NodePort --dry-run=client -o yaml > xxl-job-executor-svc.yaml
