dolphinscheduler docker部署海豚mysql版本，docker重新封装正在运行服务为镜像

1.官方文档：

https://dolphinscheduler.apache.org/zh-cn/docs/3.2.1/guide/installation/standalone#%E9%85%8D%E7%BD%AE%E6%95%B0%E6%8D%AE%E5%BA%93

2.github:

dolphinscheduler/docs/docs/zh/guide/howto/datasource-setting.md at 3.2.1-release · apache/dolphinscheduler · GitHub

3. 场景描述：

启动dolphinscheduler-stand-server版本，并想设置为mysql数据库

4. 问题描述：

由于开源问题 mysql 需要手动打入容器内部，才能启动成功。主要解决此问题，并使用docker-compose 设置env 为mysql 来启动dolphinscheduler-standalone-server

5. 方案：

1. 设置mysql 驱动映射，docker-compse.yml 设置映射，全部映射进去

2. h2数据库启动后，打新镜像。

docker-compose.yml:

6. 方案1 解决很简单，映射进容器内，就解决了。mysql 下载地址：

Centsdfepository: mysql/mysql-connector-java

然后创建文件夹放入/data/dolphinscheduler/libs/mysql-connector-java-8.0.16.jar

或者修改为你自己docker-compose 路径

启动：docker-compose up -d dolphinscheduler

方案二.步骤：

1.docker-compse 先启动一个h2内置数据库 dolphinscheduler-standalone-server

2. 启动服务后，然后docker cp mysql驱动,到指定位置

3. 将运行服务重新打镜像

步骤1. 首先docker pull 下来官方镜像：

docker pull apache/dolphinscheduler-standalone-server:3.2.1

2. 我使用的docker-compose 启动

docker-compose up -d dolph2

3. 启动成功后 docker cp 进去mysql驱动

   docker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs/api-serverdocker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs/master-serverdocker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs/alert-serverdocker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs/worker-serverdocker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs/standalone-serverdocker cp mysql-connector-java-8.0.16.jar  dolph2:/opt/dolphinscheduler/libs

4. 可以进入服务校验下是否添加进入
