docker安装flink应用

1.安装docker

docker install

查看是否安装成功：docker version

 因为已经安装过，会提示无法连接，systemctl start docker 就可以启动

2.安装docker-compose

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

3.用docker-compose安装flink

使用docker拉取镜像     docker pull flink

写好docker-compose.yml文件，在它所在的文件夹下运行docker-compose up -d 

version: "2.1"
services:
  jobmanager:
    image: flink
    expose:
      - "6123"
    ports:
      - "8081:8081"
    command: jobmanager
    environment:
      - JOB_MANAGER_RPC_ADDRESS=jobmanager
 
  taskmanager:
    image: flink
    expose:
      - "6121"
      - "6122"
    depends_on:
      - jobmanager
    command: taskmanager
    links:
      - "jobmanager:jobmanager"
    environment:
      - JOB_MANAGER_RPC_ADDRESS=jobmanager

4.查看docker 镜像，已经有flink

5.查看启动的容器

 flink,redis已启动

6.浏览器打开 http://127.0.0.1:8081 可以看到dashboard

 这样环境就搭建好啦~
