在k8s集群以session模块部署flink

Flink On K8S

1. 在需要安装的集群上执行

   wget --no-check-certificate https://dlcdn.apache.org/flink/flink-1.15.3/
   

​ 下载flink1.15.3版本

2. 执行以下命令解压文件

   tar zxvf flink-1.15.3-bin-scala_2.12.tgz 
   

3. 配置kubectl yum源，安装kubectl，将访问k8s集群证书拷贝到/root/.kube目录下

   cat <<EOF > /etc/yum.repos.d/kubernetes.repo
   [kubernetes]
   name=Kubernetes
   baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
   enabled=1
   gpgcheck=1
   repo_gpgcheck=1
   gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
   EOF
   yum install kubectl
   

4. flink文件夹下执行以下命令部署session模式的flink，具体参数参考文档https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/deployment/config/#kubernetes-container-image-pull-secrets

   # 提前为flink创建好k8s的service account
   kubectl -n cvis-crossroad-dev create serviceaccount flink-service-account
   # 为flink账号绑定访问权限
   kubectl create clusterrolebinding flink-role-binding-flink --clusterrole=edit --serviceaccount=cvis-crossroad-dev:flink-service-account
   #创建session模式的flink服务
   ./bin/kubernetes-session.sh     -Dkubernetes.cluster-id=cvis-my-first-flink-cluster     -Dexecution.attached=true -Dkubernetes.namespace=cvis-crossroad-dev -Dkubernetes.service-account="flink-service-account"
