1.基于alpine制作nginx镜像

1.1 拉取alpine镜像

[root@vm1 ~]# docker pull alpine:latest
latest: Pulling from library/alpine
Digest: sha256:3c7497bf0c7af93428242d6176e8f7905f2201d8fc5861f45be7a346b5f23436
Status: Image is up to date for alpine:latest
docker.io/library/alpine:latest

1.2 编写dockerfile

[root@vm1 ~]# mkdir alpine-nginx
[root@vm1 ~]# cd alpine-nginx/
[root@vm1 alpine-nginx]# vim Dockerfile 
FROM alpine:latest
LABEL MAINTAINER="wisan 619585019@qq.com"
RUN echo -e "http://mirrors.aliyun.com/alpine/v3.9/main\nhttp://mirrors.aliyun.com/alpine/v3.9/community" > /etc/apk/repositories     && apk add nginx     && mkdir -p /html/nginx     && echo "hello world !" > /html/nginx/index.html     && mv /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
EXPOSE 80
COPY ./nginx.conf /etc/nginx/nginx.conf
CMD ["nginx","-g","daemon off;"]

1.3 nginx配置文件

[root@vm1 alpine-nginx]# vim nginx.conf 
user                            nginx;
worker_processes                auto;
error_log                       /var/log/nginx/error.log;
pid                             /run/nginx.pid;

events {
    worker_connections          1024;
}

http {
    include                     /etc/nginx/mime.types;
    default_type                application/octet-stream;
    sendfile                    on;
    access_log                  /var/log/nginx/access.log;
    keepalive_timeout           3000;
    server {
        listen                  80;
        server_name             localhost;
        client_max_body_size    32m;
        location / {
            root                    /html/nginx;
            index                   index.html;
        }
    }
}
[root@vm1 alpine-nginx]# ls
Dockerfile  nginx.conf

1.4 build生成镜像

[root@vm1 alpine-nginx]# docker build -t xpengzong/nginx:v1 .
