?創建docker私有倉庫的目的在于私密性，適用于團體內部，如公司部門，企業內部等需要在團體成員中共享docker相關資源的場景。
?那么如何搭建屬于自己企業或團體成員可以使用的docker私有倉庫呢？筆者將通過下面的實際搭建流程結合步驟描述來介紹docker私有倉庫搭建的具體過程。

實際案例搭建過程
1、下載registry鏡像
[root@localhost ~]# docker pull registry Using default tag: latest latest: Pulling from library/registry 486039affc0a: Pull complete ba51a3b098e6: Pull complete 8bb4c43d6c8e: Pull complete 6f5f453e5f2d: Pull complete 42bc10b72f42: Pull complete Digest: sha256:7d081088e4bfd632a88e3f3bcd9e007ef44a796fddfe3261407a3f9f04abe1e7 Status: Downloaded newer image for registry:latest docker.io/library/registry:latest 2、生成registry容器，開放5000端口
[root@localhost ~]# docker create -it registry /bin/bash fd51aa59dc5cea7b589d0403e562cb8f0098c3a8a7da239572dd5bfd9423ec96 [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fd51aa59dc5c registry "/entrypoint.sh /bin…" 10 seconds ago Created optimistic_saha #建議直接執行下面的這個命令，因為筆者遇到start這個容器發現退出的狀態碼非0（后面解決了，使用/bin/sh環境即可） [root@localhost ~]# docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry ceb498d622ab743fc858a993e3870f9831e20436cb71f7225215f1f0899571f1 [root@localhost ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES ceb498d622ab registry "/entrypoint.sh /etc…" 2 seconds ago Up 2 seconds 0.0.0.0:5000->5000/tcp strange_swanson docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry命令的解釋：
-d ——守護進程
-v ——數據卷設置{/data/registry表示的宿主機系統中的一個絕對路徑，沒有的時候會自動創建，/tmp/registry表示容器內部的目錄}
#宿主機目錄
[root@localhost ~]# ls / bin boot data dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var [root@localhost ~]# ls /data/ registry #容器內部目錄
[root@localhost ~]# docker exec -it ceb498d622ab /bin/sh / # ls / bin etc media root srv usr dev home mnt run sys var entrypoint.sh lib proc sbin tmp / # ls tmp/ registry 3、客戶端設置daemon.json文件 （指定私有倉庫位置）
[root@localhost ~]# vim /etc/docker/daemon.json { "insecure-registries": ["20.0.0.149:5000"], #將本地服務器作為私有倉庫位置 "registry-mirrors": ["https://5m9y9qbl.mirror.aliyuncs.com"] } [root@localhost ~]# systemctl restart docker 4、創建本地的鏡像標簽
[root@localhost ~]# docker pull httpd Using default tag: latest latest: Pulling from library/httpd 123275d6e508: Pull complete e984dd982a6e: Pull complete 963280e5cf81: Pull complete 6faf90d050b2: Pull complete 962b56984bb0: Pull complete Digest: sha256:d5dc0d279039da76a8b490d89a5c96da83a33842493d4336b42ccdfbd36d7409 Status: Downloaded newer image for httpd:latest docker.io/library/httpd:latest [root@localhost ~]# docker tag httpd:latest 20.0.0.149:5000/httpd 5、上傳鏡像
[root@localhost ~]# docker push 149:5000/httpd The push refers to repository [149:5000/httpd] An image does not exist locally with the tag: 149:5000/httpd [root@localhost ~]# docker push 20.0.0.149:5000/httpd The push refers to repository [20.0.0.149:5000/httpd] 9dabb51b1ca2: Pushed 4621e8a6d1da: Pushed e728c649bc91: Pushed 1a935e59aa8a: Pushed b60e5c3bcef2: Pushed latest: digest: sha256:8f10edef61246c6c142a87304d4ffa68298662ecb619776e4e9817d06ec5f567 size: 1367 [root@localhost ~]# curl -XGET http://20.0.0.149:5000/v2/_catalog {"repositories":["httpd"]} #有上面的結果表示上傳成功6、下載鏡像測試

最后給出上面出現的狀態碼錯誤的問題具體解決
