一、compose简介
compose项目来源于之前的fig项目，使用python语言编写。compose项目主要用于编排部署docker的应用，本身与docker/swarm配合度很高
docker compose是docker编排服务的一部分，可以让用户在其他平台上快速的安装docker，dockercompose属于一个应用层的服务，用户可以定义哪个容器组运行哪个应用，它支持动态改变应用。
dockerfile可以让用户管理一个单独的容器，而compose则允许用户在一个模版yaml格式中定义一个相关联的容器，例如一个调度器，两个web服务器等。
一、我们先做一个基础的环境，用dockerfile做一个apache镜像。
以下是Apache的dockerfile。
1. #FROM docker.io/centos:centos6
2. MAINTAINER blxh@qy.com
3. RUN yum install -y httpd net-tools iputils
4. RUN sed 's/#ServerName www.example.com:80/ServerName www.benet.com/g' /etc/httpd/conf/httpd.conf
5. EXPOSE 80
6. CMD ["/usr/sbin/httpd","-DFOREGROUND"]
1.编写完成之后运行dockerfile
1. # docker build -t centos:http .
2. Sending build context to Docker daemon 2.048 kB
3. Step 1 : FROM docker.io/centos:centos6
4. Trying to pull repository docker.io/library/centos ...
5. centos6: Pulling from docker.io/library/centos
6.
7. b26de5a391ad: Downloading [=========================> ] 2.701 MB/70.04 MB
2.运行完成之后查看是否有http的镜像
1. # docker images
2. REPOSITORY TAG IMAGE ID CREATED SIZE
3. centos http 33e4acf38103 24 seconds ago 302 MB
4. docker.io/centos centos6 5dedbd63518e 9 days ago 194.3 MB
3.编写nginx-dockerfile，以下的nginx的dockerfile
1. #images of nginx
2. FROM docker.io/centos:centos6
3. RUN yum install -y pcre-devel wget net-tools gcc zlib zlib-devel make openssl-devel
4. RUN useradd -M -s /sbin/nologin nginx
5. ADD http://nginx.org/download/nginx-1.6.2.tar.gz .
6. RUN tar zxvf nginx-1.6.2.tar.gz
7. RUN mkdir -p /usr/local/nginx
8. RUN cd nginx-1.6.2 && ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module && make && make install
9. RUN ln -s /usr/local/nginx/sbin/* /usr/local/sbin/
10. copy nginx.conf /usr/local/nginx/conf/nginx.conf
11. expose 80
12. CMD ["nginx"]
4.注意以上红色字段，我们需要拷贝一份nginx在当前目录。以下是nginx主配置内容
1. # ls
2. dockerfile nginx.conf
3. vim nginx.conf
4. #user nobody;
5. worker_processes 1;
6.
7. #error_log logs/error.log;
8. #error_log logs/error.log notice;

125. daemon off;
5.随后运行nginx-dockerfile 注意那个后面的小点，代表当前位置。
1. # docker build -t centos:nginx .
2. Sending build context to Docker daemon 6.144 kB
3. Step 1 : FROM docker.io/centos:centos6

6. ---> Running in 4c25bd1ebd47
7. Loaded plugins: fastestmirror, ovl
8. Setting up Install Process
运行完之后我们查看是否有nginx镜像
1. # docker images
2. REPOSITORY TAG IMAGE ID CREATED SIZE
3. centos nginx 155c0c66b4fc 41 seconds ago 316.4 MB
4. centos http 33e4acf38103 19 minutes ago 302 MB

二、安装compose，在安装docker-compose时，先安装pip，pip就相当于redhat里面的yum
以下是安装的过程
1. # wget https://bootstrap.pypa.io/get-pip.py
