dockerfile制作编译安装nginx镜像并用docker-compose部署

先上文件结构

compose_nginx/
├── docker-compose.yml
├── nginx
│   ├── Dockerfile
│   └── nginx-1.12.2.tar.gz
└── wwwroot
    └── index.html	

使用dockerfile制作一个自定义的镜像，镜像中编译安装nginx-1.12.2

nginx的源码包可到nginx的官网下载

下面是各文件内容：

docker-compose.yaml

version: '3'
services:
  nginx:                      # 服务名称为nginx
    hostname: nginx
    build:
      context: ./nginx
      dockerfile: Dockerfile	# 指定dockerfile
    ports:
    - 1215:80
    - 1216:443
    networks:
    - cluster					# 网络命名空间
    volumes:
    - ./wwwroot:/usr/local/nginx/html	# 挂载
networks:
  cluster:

Dockerfile

自定义的镜像，里面编译安装了nginx

FROM acktsw/centos
MAINTAINER this is for docker-compose
ADD nginx-1.12.2.tar.gz /usr/local/src
RUN yum -y install gcc gcc-c++ make pcre* zlib-devel
RUN useradd -M -s /sbin/nologin nginx
WORKDIR /usr/local/src
WORKDIR nginx-1.12.2
RUN ./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module && make && make install
RUN ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
EXPOSE 80
EXPOSE 443
RUN echo "daemon off;" >> /usr/local/nginx/conf/nginx.conf
CMD ["nginx"]

镜像下载速度较慢，可尝试将镜像修改为centos:7

wwwroot目录下的index.html则可以自定义

echo "docker-compose nginx" >>  wwwroot/index.html

启动

docker-compose -f docker-compose.yml up -d

-d 后台启动

-f 指定yml文件

部分部署过程：

待部署完成后，尝试访问

注意指定端口1215

[root@localhost compose_nginx]# curl 127.0.0.1:1215
docker-compose nginx

部署成功！
