dockerfile 启动服务导致在宿主机打印log

Question

我是用ubuntu为基础镜像制作了一个新镜像（new_ubuntu)，内包含mysql ，FlaskApp 。
但是我启动新镜像内部的mysql 和 flask server 没有启动

我的解决方法，使用dockerfile 依据 new_ubunt 重新构建镜像，指定mysql 和 flask server自启动

我的Dockerfile

From lijian_docker
WORKDIR /funds
COPY run_server.sh .
CMD ["/bin/sh", "run_server.sh"]

我的run_server.sh

#!/bin/sh
service mysql start 
gunicorn manage:app -c gunicorn.conf.py

运行 ：docker run --name my_ubuntu3 -p 3308:3306 -p 5000:5000 my_ubuntu3

会在我的宿主机打印以下内容并占据终端

* Starting MySQL database server mysqld
   ...done.

Answer 1

docker里面不能用service mysql start 和systemctl启动服务的，需要进入到服务的目录里，用可执行文件去启动目录
