>>> docker compose up
Could not create connection to database server

解决方案：
1 查问docker mysql ip address

>>> docker inspect mysql | grep IPAddress# 172.18.0.2

2 替换docker-compose.yaml文件中 PARAMS spring.datasource.url值

--spring.datasource.url=jdbc:mysql://mysql:3306/xxl_job替换为--spring.datasource.url=jdbc:mysql://172.18.0.2:3306/xxl_job

3 docker compose up 连贯胜利
