Dockerfile多阶段构建nginx镜像

一、多阶段构建nginx镜像-编译格式

1、镜像文件说明

“skillfir/alpine:gcc”：基于alpine3.14制作成的gcc镜像，apk源调整为中科大，同时WORKDIR=/usr/src；

“skillfir/alpine:glibc”：基于alpine3.14制作而成，apk源调整为中科大，同时解决了中文乱码及时区问题。

2、Dockerfile示例

2.1 项目目录结构

.
├── default.conf
├── Dockerfile
└── nginx.conf

2.2 Dockerfile内容

#第1阶段

2.4 default.conf配置文件

server {
    listen       80;
    listen  [::]:80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;

2.5 制作镜像

#制作镜像
docker built -t alpine:nginx .
#查看镜像
docker images 
	alpine           nginx     d5bb514e4046   2 hoursago     76.1MB
	<none>          <none>     7ae8802124c7   9 seconds ago    272MB   //第一 阶段产生的临时镜像

2.6 镜像测试

docker run -d --rm --name nginx -v /data/nginx/html:/usr/share/html:ro -p 80:80 alpine:nginx
echo "welcome to my nginx-test" >/data/nginx/html/index.html

二、多阶段构建nginx镜像-在线安装

FROM skillfir/alpine:glibc
LABEL AUTHER="WEIPENG <weipeng@facefinding.cn>"
RUN apk update &&\
    apk add --no-cache nginx 
ADD nginx.conf /etc/nginx/
ADD default.conf /etc/nginx/conf.d
EXPOSE 80
CMD ["nginx","-g","daemon off;"]
