一、建立自己的 docker registry 主機

參考docker registry 來源：https://hub.docker.com/_/registry

環境：CentOS 7

• Docker-Registry：私倉主機(docker-registry.com.cc:5000)
• nginx：連線至Docker_Registry主機進行 image push 流程

Docker-Registry主機上執行指令：docker run -d -p 5000:5000 -v /home/docker-registry/storage:/var/lib/registry --name registry registry:latest

[root@Docker-Registry ~]# docker run -d -p 5000:5000 -v /home/docker-registry/storage:/var/lib/registry --name registry registry:latest
Unable to find image 'registry:latest' locally

指令說明：

-d 背景執行
-p 5000:5000 使用5000 port
-v 將本地的 /home/docker-registry/storage 關連至 /var/lib/registry
–name docker令名，可自定
registry:latest 取得docker hub 上 registry 最新的版本

建立完成後，可執行 docker ps -a 查看是否正常運行

[root@Docker-Registry ~]# docker ps -a
