基于docker的centos:latest镜像制作nginx的镜像

663424

Dockerfile和nginx.repo在同一目录下
先创建nginx.repo

1 2 3 4 5 6 7 8

[iyunv@localhost nginx]# cat nginx.repo [nginx] name=nginx repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=0 enabled=1 [iyunv@localhost nginx]# ls Dockerfile  nginx.repo

写dockerfile

1 2 3 4 5 6 7 8 9 10 11 12 13

[iyunv@localhost nginx]# cat Dockerfile # This is My first Dockerfile # Version 1.0 # Author: Liuzhengwei # Base images FROM centos:base_newlatest MAINTAINER mail:1135960569@qq.com 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"]

创建镜像：

1 2 3 4 5 6 7 8

[iyunv@localhost 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

运行此镜像：

1 2	[iyunv@localhost nginx]# docker run -d -p 80 nginx-file:v1 6e43d596879c2b67fc74143957ef914ef842d78046812717919e576a629f694c

查看容器是否启动正常：

1 2 3

[iyunv@localhost 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

进入此容器：

1 2 3 4 5

[iyunv@localhost nginx]# docker exec -it 6e43d596879c bash [iyunv@6e43d596879c /]# 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 [iyunv@6e43d596879c /]# ss -tnl
