Docker Hub 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 registry
Unable to find image 'registry:latest' locally

上传镜像到私有仓库
创建好私有仓库之后,我们就可以向该仓库上传镜像,别人也可以从该仓库下载镜像了。
查看本地已有的镜像:
guohl@ghl-MBP ⮀ ~ ⮀ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
nginx latest 637d3b2f5fb5 4 days ago 93.44 MB
MySQL latest 0feafece277d 11 days ago 282.9 MB
wordpress latest f90659c8fdb9 2 weeks ago 451.5 MB
Ubuntu latest d0955f21bf24 4 weeks ago 188.3 MB
google/golang latest 3cc1d7ae0e9c 11 weeks ago 611.3 MB
hello-world latest e45a5af57b00 3 months ago 910 B
通过 docker tage
命令将 hello-world
这个镜像标记为 192.168.59.104:5000/hello-world
之后,再 push 到该镜像到私有仓库:
guohl@ghl-MBP ⮀ ~ ⮀ docker tag hello-world 192.168.59.104:5000/hello-world
guohl@ghl-MBP ⮀ ~ ⮀ docker push 192.168.59.104:5000/hello-world
FATA[0000] Error: v1 ping attempt failed with error: Get https://192.168.59.104:5000/v1/_ping: dial tcp 192.168.59.104:5000: connection refused. 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 SO 上类似问题 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 withboot2docker 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 registry
4935607095a22655da1ef91feb6f569264a50529cb8d594d520fe62da81250db
guohl@ghl-MBP ⮀ ~ ⮀ docker push 192.168.59.104:5000/test
The push refers to a repository [192.168.59.104:5000/test] (len: 1)
Sending image list
Pushing repository 192.168.59.104:5000/test (1 tags)
511136ea3c5a: Image successfully pushed
31cbccb51277: Image successfully pushed
e45a5af57b00: Image successfully pushed
Pushing tag for rev [e45a5af57b00] 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": [{"description":"", "name": "library/hello-world"}]}%
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-world
Untagged: 192.168.59.104:5000/hello-world:latest
