使用Dockerfile制作基于Centos7的Nginx应用镜像

创建Dockerfile

FROM centos:7
MAINTAINER "WWW"
RUN yum install -y http://nginx.org/packages/centos/7/x86_64/RPMS/nginx-1.24.0-1.el7.ngx.x86_64.rpm
COPY dest/index.html /usr/share/nginx/html/
EXPOSE 80/tcp
ENTRYPOINT ["nginx", "-g", "daemon off;"]

创建镜像

#目录结构
[root@docker nginx]# tree /root/dockerfile/
/root/dockerfile/
└── nginx
    ├── dest
    │   └── index.html
    └── Dockerfile

[root@docker nginx]# docker build -t centos:v1.1 ./
[root@docker nginx]# docker images
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
centos       v1.1      90714e48dcba   2 minutes ago   431MB

上传镜像-harbor

修改hosts文件

[root@docker nginx]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.110.139 www.kvm.cn

修改daemon.json

{
  "registry-mirrors": ["https://hnjwpdu9.mirror.aliyuncs.com"],
  "insecure-registries": ["www.kvm.cn"]
}

重启DOCKER

[root@docker nginx]# systemctl restart docker.service

登录并上传

[root@docker nginx]# docker login www.kvm.cn
Username: admin
