Docker镜像制作：Nginx

安装Nginx

# vim Dockerfile

FROM centos
 
MAINTAINER Edward
 
RUN yum install epel-release -y && yum install nginx -y
 
#USER nginx
 
#ENV MYSQL_HOST 192.168.50.60

# docker build -t nginx:v2 .

# docker run -it --rm nginx:v2 bash

看看nginx是否安装成功

[root@713aae3c10ea /]# ls /usr/share/nginx/

 

写个默认欢迎页面

# vim /opt/nginx-v1/index.html

linux nginx web

继续制作镜像，编辑dockerfile

# vim Dockerfile

FROM centos

MAINTAINER Edward

RUN yum install epel-release -y && yum install nginx -y

#USER nginx

#ENV MYSQL_HOST 192.168.50.60


add index.html /usr/share/nginx/html/

EXPOSE 80 443

CMD ["nginx"]

将新增内容写在文件尾部，这样前面执行完的步骤会跳过，不会重复执行，也不容易出错

 

进入容器

# docker run -it --rm -p 80:80 nginx:v2 bash

安装sz工具

[root@713aae3c10ea /]# yum install lrzsz -y

拿到nginx配置文件

[root@713aae3c10ea /]# sz /etc/nginx/nginx.conf

编辑配置文件，加上daemon off;

# vim nginx.conf

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
daemon off;

 

编辑dockerfile，将配置文件覆盖容器内的默认nginx.conf

# vim Dockerfile

FROM centos

MAINTAINER Edward

RUN yum install epel-release -y && yum install nginx -y

#USER nginx

#ENV MYSQL_HOST 192.168.50.60

ADD nginx.conf /etc/nginx/
add index.html /usr/share/nginx/html/

EXPOSE 80 443

CMD ["nginx"]

 

再次build(会自动调用缓存，以跳过已经完成的步骤)

# docker build -t nginx:v2 .
