简介： Flink-12 Flink Java 3分钟上手 Kubernetes云原生下的Flink集群 Rancher Stateful Set yaml详细扩容缩容部署 Docker容器编排

代码仓库

会同步代码到 GitHub

https://github.com/turbo-duck/flink-demo

背景介绍

单机模式

在之前的章节中，已经验证过，但是实际运行的时候，我们是需要提交到服务器去运行的。

集群模式

在之前章节中，已经验证过，(方便测试) 使用了 Docker 的方式进行部署。同时也利用容器编排工具docker-compose的方式，进行集群的模式部署：

简单测试 1 x JobManager + 1 x TaskManager

集群模式 1 x JobManager + 3 x TaskManager

HA模式 2 x JobManager + Zookeeper + 3 x TaskManager

但是对于上述的 docker-compose 编排的方式，我们依然是在一台机器上的。对于实际的生产情况，我们可能需要面对多台机器进行部署，同时最好的方案是：动态扩容、动态缩容，最大程度的利用资源。

云原生部署

首先确保你有 Kubernetes

然后为了简化这里借助 Rancher 可视化进行操作

等熟悉了，你可以使用 yaml尝试部署。

最后，生产环境可借助 Helm + Flink Operator 极大简化过程。

JobManager

需要开放的端口如下：

完整的Yaml 如下:

扩容TaskManager

当我们对 TaskManager 进行扩容的时候，这里我扩展了 5个，正在逐步扩容，完毕之后，我们可以对应观察到控制台中的：

同样的操作，你需要在 K8s 集群中用如下的方案来做高可用方案:

3 x JobManager
N x TaskManager
