基於docker的centos:latest映象製作nginx的映象

Dockerfile和nginx.repo在同一目錄下
先建立nginx.repo
[[email protected] nginx]# cat nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1 [[email protected] nginx]# ls Dockerfile nginx.repo
寫dockerfile
[[email protected]nginx]# cat Dockerfile # This is My first Dockerfile # Version 1.0 # Author: Liuzhengwei # Base images FROM centos:base_newlatest MAINTAINER mail:[email protected] ADD nginx.repo /etc/yum.repos.d RUN yum install nginx -y RUN echo "daemon off;" >> /etc/nginx/nginx.conf RUN useradd -s /sbin/nologin -M www EXPOSE 80 CMD ["nginx"]
建立映象：
[[email protected] nginx]# docker build -t nginx-file:v1 . ...... Removing intermediate container 57b75e5a35e7 Step 8/8 : CMD nginx ---> Running in 062fddcc03ed ---> f4a750280b72 Removing intermediate container 062fddcc03ed Successfully built f4a750280b72
執行此映象：
[[email protected] nginx]# docker run -d -p 80 nginx-file:v1 6e43d596879c2b67fc74143957ef914ef842d78046812717919e576a629f694c
檢視容器是否啟動正常：
[[email protected] nginx]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6e43d596879c nginx-file:v1 "nginx" 7 minutes ago Up 7 minutes 0.0.0.0:32774->80/tcp sleepy_shannon
進入此容器：
[[email protected] nginx]# docker exec -it 6e43d596879c bash [[email protected] /]# ps -ef | grep nginx root 1 0 0 15:58 ? 00:00:00 nginx: master process nginx nginx 7 1 0 15:58 ? 00:00:00 nginx: worker process
