centerOS docker搭建flowable，流程引擎

1、准备一个mysql数据库，库名为flowable
2、mysql驱动下载，下载地址为：

https://mvnrepository.com/artifact/mysql/mysql-connector-java

此处使用的是8.0.22版本的驱动，且数据库必须使用版本8，否则第二次启动报错
3、新建目录

mkdir -p /home/flowable/mysqlDriver/

将上面下载的mysql驱动放到mysqlDriver目录下
4、新建docker-compose.yml文件

version: '3'
services:
  flowable-ui:
    image: flowable/flowable-ui
    container_name: flowable-ui
    restart: always
    volumes:
      - "/home/flowable/mysqlDriver/mysql-connector-java-8.0.22.jar:/app/WEB-INF/lib/mysql-connector-java-8.0.22.jar"
    environment:
      - spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver 
      - spring.datasource.url=jdbc:mysql://localhost:3306/flowable?allowMultiQueries=true&useUnicode=true&characterEncoding=UTF8&serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=convertToNull&useSSL=false&nullCatalogMeansCurrent=true
      - spring.datasource.username=root       
      - spring.datasource.password=xxxxxx       
      - flowable.async-executor-activate=false 
      - flowable.database-schema-update=true   
    ports:
      - "9010:8080"

5、进入目录cd /home/flowable后执行docker-compose up -d 启动容器
6、访问地址：http://IP:9010/flowable-ui/
