# Flink Operations Playground
>该docker部署方式借助于flink官方的docker-compose部署指南 

The Flink operations playground lets you explore and play with [Apache Flink](https://flink.apache.org)'s features to manage and operate stream processing jobs, including

* Observing automatic failure recovery of an application
* Upgrading and rescaling an application
* Querying the runtime metrics of an application

It's based on a [docker-compose](https://docs.docker.com/compose/) environment and is super easy to setup.





# 部署docker-compose

1. 在`./operations-playground` 文件夹下执行 `docker-compose build`命令
2. 如果是在linux环境下 执行
```bash
mkdir -p /tmp/flink-checkpoints-directory
mkdir -p /tmp/flink-savepoints-directory
```
如果是windows 环境不能这样操作，但是依然可以运行 只不过不会保存ck与sp

3. 恢复已经打包的镜像 `docker load -i images.tar` 容器群的启动与恢复 
```sh
docker-compose up -d
```
和
```sh
docker-compose down
```
4. 如果一切正常的话 界面如下

5. 启动tomcat服务器与后端的springboot项目
    已经写好了sh文件，打开jobmanager的命令行，在/opt/flink/bin/ 中执行
    ```sh
    sh test.sh
    ```

6. 此时访问`localhost:8080/web`可以看到前端页面

7. 关于容器的导出（在windows下需要借助wsl2执行）

```sh
docker-compose images| awk 'FNR > 2 {print $2":"$3}'| sort -u|xargs docker save -o images.tar
```

生成的压缩包`images.tar`即为全部的容器导出文件，可通过上述方式重新在其他宿主机部署


> 帮助命令

mysql启动 ：
```
service mysql restart
```

springboot启动命令 - 后台运行并将日记记录至`/opt/flink/bin/catalina.out`文件
```
 nohup java -jar  /opt/flink/bin/metaflink-0.0.1-SNAPSHOT.jar  > /opt/flink/bin/catalina.out  2>&1 &
```
