使用docker的login命令之后，可以使用push命令将镜像推送到dockerhub上，但是dockerhub毕竟在公网上，免费的帐户只有一个private 的repository是免费的，剩下的就都只能做成public的。由于种种限制，企业私有仓库的创建就有了各种应用场景。本文将从使用registry的方式简单介绍如何搭建私有的repository.

pull registry镜像

使用到的registry镜像

[root@liumiaocn ~]# docker search registry |head -n2NAME                                      DESCRIPTION                                     STARS     OFFICIAL   AUTOMATEDregistry                                  Containerized docker registry                   1123      [OK][root@liumiaocn ~]# docker pull registryUsing default tag: latestlatest: Pulling from library/registryc0cb142e4345: Pull completea5002dfce871: Pull completedf53ce740974: Pull complete9ce080a7bfae: Pull complete517dc3530502: Pull completeDigest: sha256:1cfcd718fd8a49fec9ef16496940b962e30e3927012e851f99905db55f1f4199Status: Downloaded newer image for registry:latest[root@liumiaocn ~]#

docker run创建私有仓库

registry的介绍提到的最佳实践建议将registry作为容器运行起来。

[root@liumiaocn ~]# docker run -d -p 5000:5000 registrybadf822f34751979e4f7fc513b40177f941b227c7385245ad2f391737587b117[root@liumiaocn ~]# docker psCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMESbadf822f3475        registry            "/entrypoint.sh /etc/"   3 seconds ago       Up 2 seconds        0.0.0.0:5000->5000/tcp   sharp_khorana[root@liumiaocn ~]#

向私有仓库push一个镜像

准备：pull一个busybox

[root@liumiaocn ~]# docker pull busyboxUsing default tag: latestlatest: Pulling from library/busybox56bec22e3559: Pull completeDigest: sha256:29f5d56d12684887bdfa50dcd29fc31eea4aaf4ad3bec43daf19026a7ce69912Status: Downloaded newer image for busybox:latest[root@liumiaocn ~]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEbusybox             latest              e02e811dd08f        9 days ago          1.093 MBregistry            latest              541a6732eadb        3 weeks ago         33.27 MB[root@liumiaocn ~]#

从私库中pull镜像

事前准备：将其他镜像都删除，以便确认该镜像确实是从私有仓库中pull出来的

[root@liumiaocn ~]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEregistry            latest              541a6732eadb        3 weeks ago         33.27 MB[root@liumiaocn ~]#
