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
$ bin/flink run -d -m 192.168.56.103:8081 -c com.xchenhao.Demo flink-cdc-1.0-SNAPSHOT-jar-with-dependencies.jar

保存 savepoint
bin/flink savepoint 9f70a7c1430d609eaa3434c4f30d1e93 file:///opt/flink/savepoint -m 192.168.56.103:8081
