安装
# 二进制包安装
curl -L https://github.com/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
# 为安装脚本添加执行权限
chmod +x /usr/local/bin/docker-compose
docker-compose --version
# bash 补全命令
curl -L https://raw.githubusercontent.com/docker/compose/1.8.0/contrib/completion/bash/docker-compose > /etc/bash_completion.d/docker-compose
curl -L https://raw.githubusercontent.com/docker/compose/$(docker-compose version --short)/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose
# 卸载
rm /usr/local/bin/docker-compose
# 自动构建镜像并使用镜像启动容器
docker-compose up [-d 后台启动]
#Docker Compose将所管理的容器分为三层，分别是工程（project），服务（service）以及容器（container）。
#Docker Compose运行目录下的所有文件（docker-compose.yml, extends文件或环境变量文件等）组成一个工
#程（默认为docker-compose.yml所在目录的目录名称）。一个工程可包含多个服务；每个服务中定义了容器
#运行的镜像、参数和依赖，一个服务可包括多个容器实例。
docker-compose.yml常用命令
# build 配置构建时的选项
build: ./dir
build:
context: ./dir
dockerfile: Dockerfile-alternate
args:
buildno: 1
# command 覆盖容器启动后默认执行的命令
command: bundle exec thin -p 3000
command: [bundle, exec, thin, -p, 3000]
# dns 配置dns服务器
dns: 8.8.8.8
dns:
- 8.8.8.8
- 9.9.9.9
# dns_search 配置DNS的搜索域名
dns_search: example.com
dns_search:
- dc1.example.com
- dc2.example.com
# environment 环境变量设置
environment:
RACK_ENV: development
SHOW: 'true'
SESSION_SECRET:
environment:
- RACK_ENV=development
- SHOW=true
- SESSION_SECRET
# env_file 从文件中获取环境变量，可指定一个文件路径或路径列表
#通过 docker-compose -f FILE 指定了Compose文件，那么env_file中的路径是Compose文件所在目录的相对路径
#使用environment指定的环境变量会覆盖env_file指定的环境变量
env_file: .env
env_file:
- ./common.env # 共用
- ./apps/web.env # web用
- /opt/secrets.env # 密码用
# expose 暴露端口，只将端口暴露给连接的服务，而不暴露给宿主机
expose:
- "3000"
- "8000"
# external_links 连接到docker-compose.yml外部的容器，甚至并非Compose管理的容器
external_links:
- redis_1
- project_db_1:mysql
- project_db_1:postgresql
# image 指定镜像名称或镜像id，如果本地不存在该镜像，Compose会尝试下载该镜像
image: java8
# links 连接到其他服务的容器。可以指定服务名称和服务别名（ SERVICE:ALIAS ），也可只指定服务名称
web:
links:
- db
- db:database
- redis
services:
proxy:
build: ./proxy
networks:
- front

https://docs.docker.com/compose/compose-file/
networks:
default:
# Use a custom driver
driver: custom-driver-1
# 使用已存在的网络
external:
name: my-pre-existing-network
front:
# Use a custom driver
driver: custom-driver-1
back:
# Use a custom driver which takes special options
driver: custom-driver-2
driver_opts:
foo: "1"
bar: "2"
# network_mode 设置网络模式
network_mode: "bridge"
network_mode: "host"
network_mode: "none"
network_mode: "service:[service name]"
network_mode: "container:[container name/id]"
# ports 暴露端口信息 可使用HOST:CONTAINER 的格式，也可只指定容器端口（此时宿主机将会随机选择端口），类似于docker run -p
# 当使用HOST:CONTAINER 格式映射端口时，容器端口小于60将会得到错误的接口，因为yaml会把xx:yy 的数字解析为60进制。因此，建议使用字符串的形式
ports:
- "3000"
- "3000-3005"
- "8000:8000"
- "9090-9091:8080-8081"
- "49100:22"
- "127.0.0.1:8001:8001"
- "127.0.0.1:5000-5010:5000-5010"
# volumes 卷挂载路径设置 可以设置宿主机路径 （HOST:CONTAINER） ，也可指定访问模式 （HOST:CONTAINER:ro）
volumes:
# Just specify a path and let the Engine create a volume
- /var/lib/mysql
# Specify an absolute path mapping
- /opt/data:/var/lib/mysql
# Path on the host, relative to the Compose file
- ./cache:/tmp/cache
# User-relative path
- ~/configs:/etc/configs/:ro
# Named volume
- datavolume:/var/lib/mysql
# volumes_from 从另一个服务或容器挂载卷。可指定只读（ro）或读写（rw），默认是读写（rw）。
volumes_from:
- service_name
- service_name:ro
- container:container_name
- container:container_name:rw
