部署
# 下载 docker、docker-compose# docker-compose 部署
# 复制上述 docker-compose.yml 内容
$ vim docker-compose.yml# 创建 savepoint、checkpoint 目录用于保存状态数据
$ mkdir savepoint checkpoint$ docker-compose up -d
提交任务
# 下载 flink 客户端
$ wget https://archive.apache.org/dist/flink/flink-1.17.0/flink-1.17.0-bin-scala_2.12.tgz
$ tar xvf flink-1.17.0-bin-scala_2.12.tgz
$ cd flink-1.17.0-bin-scala_2.12# 提交任务
