dockerfile-镜像制作
目录
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

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 .

2. 基于alpine制作apache镜像
2.1 创建项目目录
[root@vm1 ~]# mkdir -p /root/alpine-httpd/soft
[root@vm1 ~]# cd alpine-httpd/
[root@vm1 alpine-httpd]# ls
Dockerfile soft
[root@vm1 alpine-httpd]# ls soft/
apr-1.7.0.tar.gz apr-util-1.6.1.tar.gz httpd-2.4.46.tar.gz
