使用docker-compose快速构建标准lnmt环境

前言

最近各种开发、测试、生产环境都从传统的一键LNMP（https://oneinstack.com/）升级Docker，不到10台服务器，每台服务器docker pull…Container A,B…实在太繁杂，尤其是默认的自动获取IP，特别麻烦每次部署都不一样。知道使用docker-compose编排，可以有效解决这个问题，但是一直没得空，周末抽空写了一个，刚好可以在一台新的数据仓库服务器部署。本docker-compose.yml主要解决如下几个问题：

1. 服务器批量部署服务配置
2. 解决时区问题
3. 解决IP固定问题
4. 环境变量使用

一、docker-compose简述

Docker-Compose项目是Docker官方的开源项目，负责实现对Docker容器集群的快速编排。

二、使用步骤

1.编写docker-compose.yml

代码如下：

version: '3.8'
services:

  nginx:
    image: nginx:1.19.2
    container_name: ${COMMON_DEPLOY_ENV}-nginx
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/nginx/html:/usr/share/nginx/html:ro
    restart: always
    ports:
      - "21601:80"
    environment:
      - NGINX_PORT=80
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.2

  mysql:
    image: mysql:5.7.30
    container_name: ${COMMON_DEPLOY_ENV}-mysql
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/mysql:/var/lib/mysql
    restart: always
    ports:
      - "21602:3306"
    environment:
      MYSQL_ROOT_PASSWORD: Admin2020
      MYSQL_DATABASE: db_manage
      MYSQL_USER: dev_user
      MYSQL_PASSWORD: dev_user
    networks:
        sly_net_pro:
          ipv4_address: 172.172.0.3

  tomcat:
    image: tomcat:8.5.54-jdk8
    container_name: ${COMMON_DEPLOY_ENV}-tomcat
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/tomcat/webapps:/usr/local/tomcat/webapps
    environment:
      TZ: Asia/Shanghai
    restart: always
    ports:
      - "21603:8080"
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.4

  redis:
    image: redis:5.0.9-buster
    container_name: ${COMMON_DEPLOY_ENV}-redis
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/redis/conf/redis.conf:/usr/local/etc/redis/redis.conf
    restart: always
    ports:
      - "21604:6379"
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.5

  memecached:
    image: memcached:1.6.7
    container_name: ${COMMON_DEPLOY_ENV}-memcached
    volumes:
      - /etc/localtime:/etc/localtime:ro
    restart: always
    ports:
      - "21605:11211"
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.6

  mongo:
    image: mongo:4.4.1
    container_name: ${COMMON_DEPLOY_ENV}-mongo
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/mongo:/etc/mongo
    restart: always
    ports:
      - "21606:27017"
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: Admin2020
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.7

  clickhouse:
    image: yandex/clickhouse-server:20.6.6.7
    container_name: ${COMMON_DEPLOY_ENV}-clickhouse
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ${COMMON_VOLUMENS_PATH}/clickhouse-server:/var/lib/clickhouse yandex/clickhouse-server
    restart: always
    ports:
      - "21607:8123"
    networks:
      sly_net_pro:
        ipv4_address: 172.172.0.8

networks:
  sly_net_pro:
    ipam:
      driver: default
      config:
        - subnet: "172.172.0.0/24"

2.编写.env

在同级目录下，创建.env文件，可直接调用变量，代码如下：

# define env var default value.
COMMON_VOLUMENS_PATH=/data/docker-data
COMMON_DEPLOY_ENV=pro

---

总结

把以上两个文件拷贝到同一目录下即可快速布置一个服务器的基础环境，在部署前可使用docker-compose config测试下。
