搭建docker仓库2

https://hub.docker.com/ 是 Docker 官方的公共仓库服务器，用户在 DockerHub 上只能创建一个私有仓库，这对于有些用户是不够用的，而且 DockerHub 服务器的访问速度也是个很大问题，那么我们希望能在自己本地的服务器上创建一个类似于 DockerHub 仓库服务器供团队使用，这也是可以的。我测试的环境是 Mac OSX 下，已经通过 Boot2Docker 工具安装好 Docker 的环境，通过 命令boot2docker ip 可以查看虚拟机的 IP 是 192.168.59.104。那么下面我就在自己虚拟机上搭建一个私有的 Docker 仓库服务器：安装运行 Docker-Registry运行官方提供的 registry 镜像，将端口映射到主机的 5000 端口上，其它均使用默认配置：guohl@ghl-MBP ⮀ ~ ⮀ docker run -d -p 5000:5000 registryUnable to find image ‘registry:latest’ locally6cfde7386ab2: Pull complete9789d95d9fda: Pull complete19443e64f223: Pull completeb329371ab73c: Pull completef0daee9a4e8f: Pull completea66e50e56475: Pull complete8ab3d2988df5: Pull complete5f60fa7ea945: Pull completedb22a140c899: Pull complete5b2fff9306bd: Pull complete511136ea3c5a: Already existsf3c84ac3a053: Already existsa1a958a24818: Already exists9fec74352904: Already existsd0955f21bf24: Already existsregistry:latest: The image you are pulling has been verified.

If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry 192.168.59.104:5000 to the daemon’s arguments. In the case of HTTPS, if you have access to the registry’s CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/192.168.59.104:5000/ca.crt发现报错，使用 http://stackoverflow.com/questions/28712455/pushing-files-into-private-registry-in-docker 的解决方法可以解决上面的错误：To use the --insecure-registry option, add it to the file /var/lib/boot2docker/profile inside the boot2docker VM. You can get into the VM with boot2docker ssh. The file contents should look like:EXTRA_ARGS="–insecure-registry REGISTRY_IP:PORT" You will then need to restart boot2docker (e.g. boot2docker restart).步骤如下：
使用 boot2docker ssh 登陆到 boot2docker 虚拟机
修改 /var/lib/boot2docker/profile 文件，向该文件中增加一行：EXTRA_ARGS="–insecure-registry 192.168.59.104:5000"
退出该虚拟机并使用命令 boot2docker restart 重启 boot2docker
完成重启之后，将私有仓库服务器运行起来，并 push hello-world 到该仓库：guohl@ghl-MBP ⮀ ~ ⮀ docker run -d -p 5000:5000 registry4935607095a22655da1ef91feb6f569264a50529cb8d594d520fe62da81250dbguohl@ghl-MBP ⮀ ~ ⮀ docker push 192.168.59.104:5000/testThe push refers to a repository (len: 1)Sending image listPushing repository 192.168.59.104:5000/test (1 tags)511136ea3c5a: Image successfully pushed31cbccb51277: Image successfully pushede45a5af57b00: Image successfully pushedPushing tag for rev on {http://192.168.59.104:5000/v1/repositories/test/tags/latest}使用 Docker 的 RESTful API 可以查看仓库服务器中的镜像：guohl@ghl-MBP ⮀ ~ ⮀ curl http://192.168.59.104:5000/v1/search{“num_results”: 1, “query”: “”, “results”: }%表示 hello-world 镜像已成功长传至私有仓库服务器了。从私有仓库中下载、搜索镜像其他机器可以从私有仓库服务器上下载、搜索镜像等，与从 Docker Hub 上操作无异，只不过需要指出仓库的位置，如：guohl@ghl-MBP ⮀ ~ ⮀ docker rmi -f 192.168.59.104:5000/hello-worldUntagged: 192.168.59.104:5000/hello-world:latestDeleted: e45a5af57b00862e5ef5782a9925979a02ba2b12dff832fd0991335f4a11e5c5Deleted: 31cbccb51277105ba3ae35ce33c22b69c9e3f1002e76e4c736a2e8ebff9d7b5dguohl@ghl-MBP ⮀ ~ ⮀ docker search 192.168.59.104:5000/hello-worldNAME DESCRIPTION STARS OFFICIAL AUTOMATEDlibrary/hello-world 0guohl@ghl-MBP ⮀ ~ ⮀ docker pull 192.168.59.104:5000/hello-worldPulling repository 192.168.59.104:5000/hello-worlde45a5af57b00: Download complete511136ea3c5a: Download complete31cbccb51277: Download completeStatus: Downloaded newer image for 192.168.59.104:5000/hello-world:latest参考资料： http://dockerpool.com/static/books/docker_practice/repository/local_repo.html
