首先需要你的nginx包

一、空目录下新建 dockerfie

mkdir -p /root/Desktop/docker/docker_demo/
cd /root/Desktop/docker/docker_demo/
vim Dockerfile
[root@foundation11 docker_demo]# ls
Dockerfile  nginx-1.14.2.tar.gz

二：编写 Dockerfile 文件，如下：

首先

vim /etc/docker/daemon.json

{
"registry-mirrors": ["https://XXXXX.aliyuncs.com"]
}

systemctl daemon-reload
systemctl restart docker
docker pull centos
docker run centos

FROM centos
MAINTAINER mhanzaipeng 493096871@qq.com
ADD nginx-1.14.2.tar.gz /usr/local/
RUN yum install -y gcc gcc-c++ glibc make autoconf openssl openssl-devel 
RUN yum install -y libxslt-devel -y gd gd-devel GeoIP GeoIP-devel pcre pcre-devel
RUN useradd -M -s /sbin/nologin nginx
WORKDIR /usr/local/nginx-1.14.2
RUN ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_module --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module && make && make install
EXPOSE 80

三：

docker build -f Dockerfile -t mynginx .

值得注意的是，这句代码最后还有一个小点，是指定 dockerfile 在当前目录中。而且镜像名称不可以有大写字符。

当ENTRYPOINT和CMD连用时，CMD的命令是ENTRYPOINT命令的参数，两者连用相当于nginx -g "daemon off;"

而当一起连用的时候命令格式最好一致（这里选择的都是json格式的是成功的，如果都是sh模式可以试一下）

CMD的命令修改为了后台

我们知道如果容器内的进程在后台运行那么容器将不会运行

现在利用v5版本镜像启动一个container，但是在启动的时候添加后面的command：

将

CMD ["-g","daemon on;"]

可以看见在后面新增了-g "daemon off;"，前面说过如果增加了命令那么Dockerfile中的CMD中的命令将不会生效

发现存在卷宗data

这个/data挂载的目录对应本机host的这个目录：

[root@foundation11 docker_demo]# touch /var/lib/docker/volumes/5d8e7504fa30a93a0c849d64024e81a0582b4fe9174b44ac5b03d83e26708e08/_data/1

就可以创建文件了

添加ONBUILD指令：

Dockerfile修改为

ONBUILD VOLUME ["/data"]

docker build -t centos_nginx:v6 .

docker run -d -p 86:80 --name=nginx6 centos_nginx:v6 -g "daemon off;"

docker exec -it nginx6 /bin/bash

发现并没有data

但是如果将Dockerfile改为
