Docker基础：Dockerfile构建nginx应用

Docker基础：Dockerfile构建nginx应用

1、创建Dockerfile文件

[root@docker ~]# cd /server/ [root@docker server]# mkdir file [root@docker server]# cd file/ [root@docker file]# vim Dockerfile [root@docker file]# cat Dockerfile #构建容器的基础镜像 FROM centos:centos7.7.1908 #容器镜像作者信息 MAINTAINER leoheng #添加URL下载的压缩包到当前目录 ADD . #运行必要的依赖服务组件 RUN yum install -y gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel wget net-tools make #添加nginx服务运行的用户 RUN useradd -M -s /sbin/nologin nginx && yum clean all #解压编译安装过程 RUN tar -zxvf nginx-1.16.1.tar.gz RUN mkdir -p /usr/local/nginx RUN cd nginx-1.16.1 && ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx && make && make install #软链接默认的nginx路径 RUN ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ #nginx服务运行后需要暴露的端口 EXPOSE 80 443 CMD ["nginx","-g","daemon off;"] [root@docker file]#

2、构建nginx镜像

[root@docker file]# docker build --rm -t nginx:v1 . [root@docker file]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx v1 c5324ed1af79 27 seconds ago 475MB

3、运行容器镜像

[root@docker file]# docker run -d -p 80:80 nginx:v1 [root@docker file]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES df2153d04f04 nginx:v12 "nginx -g 'daemon of…" 2 minutes ago Up 2 minutes 0.0.0.0:80->80/tcp, :::80->80/tcp, 443/tcp stupefied_kirch [root@docker file]# docker exec -it df2153d04f04 /bin/bash [root@df2153d04f04 /]# ps aux |grep nginx root 1 0.0 0.0 20556 1556 ? Ss 15:43 0:00 nginx: master process nginx -g daemon off; nginx 7 0.0 0.0 21004 1560 ? S 15:43 0:00 nginx: worker process root 23 0.0 0.0 9092 680 pts/0 S+ 15:46 0:00 grep --color=auto nginx [root@df2153d04f04 /]# exit

4、访问测试页面

[root@docker file]# curl 127.0.0.1 Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.
