[[email protected] ~]# yum install docker

[[email protected] ~]# systemctl start docker

[[email protected] ~]# systemctl enable docker

[[email protected] ~]# docker pull daocloud.io/registry

[[email protected] ~]# mkdir /data/local_docker_registry -p

* 測試 [ 有返回就表示成功 ]

[[email protected] ~]# curl 192.168.60.150:5000/v2
<a href="/v2/">Moved Permanently</a>.

6. 上傳鏡像至私有倉庫測試

* 編寫dockerfile文件

# Nginx 
# Version 1.0.1
# Author lisea
# Url https://lisea.cn
# Base imgae
FROM centos

# Maintainer
MAINTAINER lisea [email protected]

# Commands
RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install nginx -y
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
RUN echo "this is test nginx image" > /usr/share/nginx/html/index.html
EXPOSE 80
CMD ["nginx"]

* 通過Dockerfile構建一個新鏡像, 直接指明registry和標簽

[[email protected] nginx]# docker build -t 192.168.60.150:5000/nginx:1.0.1 .

* push 上傳鏡像到私有倉庫

[[email protected] nginx]# docker push 192.168.60.150:5000/nginx:1.0.1

* 查看鏡像是否上傳成功

[[email protected] nginx]# curl 192.168.60.150:5000/v2/_catalog
{"repositories":["nginx"]}

* 其它服務器使用此鏡像

[[email protected] nginx]# docker pull 192.168.60.150:5000/nginx:1.0.1

7. 相關問題

* 可能會出現無法push鏡像到私有倉庫的問題。這是因為我們啟動的registry服務不是安全可信賴的。 解決：

　　　1. 需要修改docker的配置文件 /etc/sysconfig/docker-network，在添加下面的內容，

    DOCKER_NETWORK_OPTIONS="--insecure-registry 192.168.60.150:5000"

2. 重啟docker

[[email protected] nginx]# systemctl restart docker

8. 總結

以需求驅動技術，技術本身沒有優略之分，只有業務之分。
