Docker Compose

介绍

  1. Compose是一个定义和管理多容器的工具，使用Python语言编写。
  2. 使用Compose配置文件描述多个容器应用的架构，比如使用什么镜像、数据卷、网络、映射端口等；
  3. 然后一条命令管理所有服务，比如启动、停止、重启等。

# 安装 docker compose 单机编排
https://docs.docker.com/compose/install/
# 下载
curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

# 增加执行权限
[root@Docker opt]# chmod  +x /usr/local/bin/docker-compose 

# 测试
[root@Docker opt]# docker-compose version
docker-compose version 1.24.1, build 4667896b
docker-py version: 3.7.3
CPython version: 3.6.8
OpenSSL version: OpenSSL 1.1.0j  20 Nov 2018

yum install pip
pip install docker-compose
  1. 定义容器环境
  2. 根据yanml文件启动容器

YAML文件格式及编写注意事项

YAML是一种标记语言很直观的数据序列化格式，可读性高。类似于XML数据描述语言，语法比XML简单的很多。
YAML数据结构通过缩进来表示，连续的项目通过减号来表示，键值对用冒号分隔，数组用中括号括起来，hash用花括号括起来。
YAML文件格式注意事项：

  1. 不支持制表符tab键缩进，需要使用空格缩进
  2. 通常开头缩进2个空格
  3. 字符后缩进1个空格，如冒号、逗号、横杆
  4. 用井号注释
  5. 如果包含特殊字符用单引号引起来
  6. 布尔值（true、false、yes、no、on、off）必须用引号括起来，这样分析器会将他们解释为字符串。
