做个简单的NGINX镜像

Dockerfile 内容如下：

FROM centos

RUN yum install -y ncurses \
    ncurses-devel \
    perl \
    cmake \
    bison \

    libxslt \
    libxslt-devel \
    openssh-clients \

    make \
    gcc \
    gcc-c++ \
    autoconf

RUN groupadd www && useradd -g www -s /sbin/nologin www
RUN mkdir -p /data/logs && chown www:www /data/logs ; \
    mkdir -p /data/web/webclose  && chown www:www /data/web  && chmod 700 /data/web/webclose ; \
    mkdir -p /data/conf/nginx ;\
    mkdir -p /usr/local/nginx ;\
    mkdir -p /dist/{dist,src}

ADD ["nginx.tar.gz","/data/conf/"]
ADD ["nginx-1.13.11.tar.gz","/dist/src/"]

RUN cd /dist/src/nginx-1.13.11 && ./configure --user=www --group=www \
        --prefix=/usr/local/nginx \
        --with-http_stub_status_module \
        --with-http_ssl_module \
        --with-http_secure_link_module && make && make install ;\
        [ -d "/usr/local/nginx/conf" ] && rm -rf /usr/local/nginx/conf && ln -sv /data/conf/nginx /usr/local/nginx/conf

CMD ["/usr/local/nginx/sbin/nginx","-g","daemon off;","-c","/data/conf/nginx/nginx.conf"]

当前目录需要的文件：

[root@docker-machine_192.168.31.129 docker]# ll
total 1008
-rw-r--r-- 1 root root    1453 Jul 18 09:59 Dockerfile
-rw-r--r-- 1 root root 1016189 Apr  4 18:01 nginx-1.13.11.tar.gz
-rw-rw-r-- 1 root root    7134 Jul 18 09:23 nginx.tar.gz

nginx.tar.gz 是自己定制好的nginx.conf、vhost等配置文件

制作镜像：

[root@docker-machine_192.168.31.129 docker]# docker  build -t my_centos_with_nginx:v1 .

启动容器：

[root@docker-machine_192.168.31.129 docker]# docker  run -i -t -d -p 80:80 my_centos_with_nginx:v1
085298fc89927068212755e94b9f5cb2f6e1553bef6edb8f105fa71a2d15e31f

查看：

[root@docker-machine_192.168.31.129 docker]# docker  ps -a

容器已经启动了，并映射到本地的80端口
可以用docker exec 进容器看看：

[root@docker-machine_192.168.31.129 docker]# docker exec -it 085298fc8992 /bin/bsh 
[root@085298fc8992 /]# ps aux
