Mysql和容器应用程序在某个主机码头

Question

我需要在同一个主机上上传应用程序容器和mysql服务器，但是容器找不到mysql服务器，你能帮我吗？

码头组成

version: '3'
services:
  proxy: 
    image: nginx
    ports:
     - "80:80"
     - "443:443"
    volumes:
     - /home/docker/nginx/default.conf:/etc/nginx/conf.d/default.conf
     - /home/docker/nginx/ssl/:/etc/nginx/ssl/
    links: 
     - zabbix-web:zabbix-web
  zabbix-web:
    image: zabbix/zabbix-web-nginx-mysql:ubuntu-latest
    links:
     - zabbix-server:zabbix-server
     - mysql-server:mysql-server
    environment:
     - MYSQL_USER=user
     - MYSQL_PASSWORD=pass
     - ZBX_SERVER_HOST=zabbix-server
     - TZ=America/Sao_Paulo
  zabbix-server:
    image: zabbix/zabbix-server-mysql:ubuntu-latest
    links:
     - mysql-server:mysql-server
    ports:
     - "10051:10051"
    volumes:
     - /home/docker/zabbix-server/script/:/usr/lib/zabbix/alertscripts
    environment:
     - MYSQL_USER=user
     - MYSQL_PASSWORD=pass
  mysql-server:
    image: mysql/mysql-server:5.6
    volumes:
     - /home/data/mysql/:/var/lib/mysql
    environment:
     - MYSQL_ROOT_PASSWORD=pass

错误

看起来您缺少了几个环境变量。

首先，在mysql-server服务中，您只指定一个MYSQL_ROOT_PASSWORD。这不会创建与zabbix-web和zabbix-server服务一起使用的用户和密码组合。您还需要指定MYSQL_DATABASE=zabbix、MYSQL_USER=user和MYSQL_PASSWORD=pass。

然后，根据Zabbix图像文档，您需要指定DB_SERVER_HOST=mysql-server，以便Zabbix知道如何访问链接的MySQL服务器。也有MYSQL_DATABASE，但是它默认为zabbix，这是我们在MySQL服务中指定要创建的，所以默认应该工作。
