利用Dockerfile构建一个nginx容器

1.从远程仓库中pull centos镜像

docker pull centos

2.查询镜像

docker images

3.下载nginx和pcre到本地目录下

4.编辑Dockerfile文件

#Nginx dockerfile

#Version 1.0

#Author: kehaojian

#Base images

FROM centos

#MAINTAINER 维护人

MAINTAINER kehaojian

#ADD 添加本地文件到镜像

ADD pcre-8.37.tar.gz /usr/local/src

ADD nginx-1.9.3.tar.gz /usr/local/src

#RUN 在镜像中执行命令

RUN yum install -y wget gcc_c++ make openssl-devel

RUN useradd -s /sbin/nologin -M www

#WORKDIR 镜像中切换到目录

WORKDIR /usr/local/src/nginx-1.9.3

RUN yum install -y gcc gcc-c++

RUN ./configure –prefix=/usr/local/nginx –user=www –group=www –with-http_ssl_module –with-http_stub_status_module –with-pcre=/usr/local/src/pcre-8.37 && make && make install

RUN echo "daemon off;">>/usr/local/nginx/conf/nginx.conf

#配置环境变量

ENV PATH /usr/local/nginx/sbin:$PATH

EXPOSE 80

#命令

CMD  ["nginx"]

5.执行构造命令  docker build -t nginx-docker:v1 .

[root@HA2 src]# docker build -t nginx-docker:v1 .

6.查看镜像 docker images

7.启动容器 docker run -it -d -p 8888:80 –name nginx8888 20c4d11561d3

8.查看容器 docker ps -l
