单机编排docker compose
Docker之旅(8)-单机编排docker compose
当在宿主机启动较多的容器时候，如果都是手动操作会觉得比较麻烦而且容易出错，
并且每个容器之间也会有先后启动的顺序依赖等。这个时候推荐使用 docker 单机
编排工具 docker-compose，docker-compose 是 docker 容器的一种单机编排服务，
docker-compose 是一个管理多个容器的工具，比如可以解决容器之间的依赖关系，
就像启动一个 nginx 前端服务的时候会调用后端的 tomcat，那就得先启动 tomcat，
但是启动 tomcat 容器还需要依赖数据库，那就还得先启动数据库，docker-compose
就可以解决这样的嵌套依赖关系，其完全可以替代 docker run 对容器进行创建、启动
和停止。
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，docker-compose 将所管理的容器分为三层，分别是工程(project)，服务
(service)及容器(container)。
docker-compose 是一个用于定义和运行多个容器 Docker 应用程序的工具。使用
Compose，可以使用 YAML 文件来配置应用程序的服务。然后，使用一个命令，从
配置中创建并启动所有服务。所以在使用 docker-compose 时编写比较规范的.yaml
或则.yml 文件是比较重要的。Compose 文件就是一个 YAML 文件，用其来定义
服务、网络和数据卷等。docker-compose 默认会在当前目录找该文件，即
./docker-compose.yml。

一. 安装 docker-compose
1.1 安装 python-pip 包管理器
在 linux 平台，安装python-pip 包会安装 pip 命令，pip 命令是一个
pyhton 安装包的安装管理工具，其类似于 ubuntu 的 apt 或者 redhat
的 yum，但是 pip 只安装 python 相关的安装包。pip 工具可以在多种
操作系统安装和使用。
Ubuntu1804 安装
root@ubuntu-suosuoli-node1:~# apt update
root@ubuntu-suosuoli-node1:~# apt install python3-pip
CentOS 安装
~$ yum install epel-release
~$ yum install -y python3-pip
1.2 安装 docker-compose
Ubuntu 1804
root@ubuntu-suosuoli-node1:~# pip3 install docker-compose
root@ubuntu-suosuoli-node1:~# docker-compose version

二. 使用 docker-compose 启动单个容器
编写 yaml 格式的 compose 文件时，可以在任意目录新建.yaml文件，并从
该目录启动容器。
2.1 编写构建单个容器的 compose 文件
编写 yml 格式的 docker-compose 文件，启动一个 nginx 服务，yaml 文档
的语法严格要求上下各行缩进的关系。
root@ubuntu-suosuoli-node1:~# mkdir /data/compose
root@ubuntu-suosuoli-node1:~# cd /data/compose
root@ubuntu-suosuoli-node1:/data/compose# vim docker-compose.yaml
service-nginx:image: nginx:compiled_V1expose:- 80- 443ports:- "80:80"- "443:443"
2.2 启动容器
在 docker compose 文件所在的目录执行docker-compose up -d
不加-d选项表示前台启动容器。
root@ubuntu-suosuoli-node1:/data/compose# docker-compose up -d
Creating compose_service-nginx_1 ... done
2.3 访问 web 测试
root@ubuntu-suosuoli-node1:/data/compose# ip addr show eth0 | grep inetinet 192.168.100.13/24 brd 192.168.100.255 scope global dynamic eth0

2.4 compose 启动的容器名
容器的在启动的时候，会给容器自定义一个名称，在 service name 后面加_1
在前面加当前目录名compose_
root@ubuntu-suosuoli-node1:/data/compose# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
9060a76a2dc4 nginx:compiled_V1 "nginx -g 'daemon of…" 2 minutes ago Up 2 minutes 0.0.0.0:80->80/tcp, 443/tcp compose_service-nginx_1
2.5 自定义容器名使用comtainer_name
root@ubuntu-suosuoli-node1:/data/compose# vim docker-compose.yaml
service-nginx:image: nginx:compiled_V1container_name: service-nginxexpose:- 80- 443ports:- "80:80"- "443:443"

docker-pr 15637 root 4u IPv6 715754 0t0 TCP *:http-alt (LISTEN)
3.4 单机编排常用命令
3.4.1 重启单个容器
使用docker-compose restart service_name重启某个容器
root@ubuntu-suosuoli-node1:/data/compose# cat docker-compose.yaml
service-nginx:image: nginx:compiled_V1container_name: service-nginxexpose:- 80- 443ports:- "80:80"- "443:443"service-tomcat-app1:image: tomcat-business:app1container_name: tomcat-app1expose:- 8080ports:- "8080:8080"
