mysql - 防止脚本在 docker 容器中退出

Question

Shell 脚本:

#!/bin/sh
service mysql start
mysql < /mysql/dockerSql.sql
service mysql stop

Docker 文件:

FROM mysql:5.6
ADD setup.sh /mysql/setup.sh
ADD dockerSql.sql /mysql/dockerSql.sql
ENTRYPOINT ["sh", "/mysql/setup.sh"]

Docker 撰写文件:

version: '3'

services:  
  nariadi-front:
    container_name: nariadi_frontend_container
    build: ./NariadiFrontEndDocker
    ports: 
        - "5002:80"
    depends_on:
        - nariadi-service

  nariadi-service:
    container_name: nariadi_backend_container
    build: ./Nariadi
    ports: 
        - "5008:5008"
    depends_on: 
        - mysql-docker-nariadi
    #command: python manage.py loaddata -t nariadi_docker -u admin

  mysql-docker-nariadi:
    build: ./docker-mysql
    ports:
        - "3310:3306"
    tty: true
    #command: --default-authentication-plugin=mysql_native_password

desktop_mysql-docker-nariadi_1 exited with code 0

当我运行 docker-compose up 时，mysql-docker-nariadi 服务存在，代码为 0。Shell 脚本正在执行，.sql 文件也正在执行。如何防止退出？

您需要在守护进程模式下运行您的镜像 - 这就是他们在官方 MySQL 镜像中的做法:

ENTRYPOINT ["mysqld"]

在您的具体情况下，您可以在入口点 SH 文件 /mysql/setup.sh 的末尾运行“mysqld”。
