如何在CentOS上创建docker注册表镜像 [英] How to create docker registry mirror on CentOS

问题描述

我尝试在docker-registry中创建镜像。我已阅读了此中的教程。并使用此中的方式。我确定我已经添加了docker守护进程的变量。我在mac OS X上成功了，但是在我的centOS上它根本不起作用。

I try and try to create mirror in docker-registry. I have read the tutorial in this. And use the way in this. I'm sure I have add variable to docker daemon. And I succeed on mac OS X. But it didn't work at all on my centOS.

我使用这个命令运行我的docker守护进程：

I run my docker daemon using this command:

docker -g /opt/apps/docker/lib --insecure-registry http://10.11.150.76:5555 --registry-mirror=http://10.11.150.76:5555 -d

我使用此命令检查docker守护进程： / p>

and I use this command to check docker daemon:

ps -ef | grep "docker"

它真的添加到docker：

It really has added to docker:

root      1232 30203  0 20:47 ?        00:00:00 docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 10022 -container-ip 172.17.0.22 -container-port 22
root      1322   735  0 20:57 pts/7    00:00:00 grep --color=auto docker
root     30202     1  0 20:15 ?        00:00:00 sudo http_proxy=http://10.16.10.129:9526/ docker -g /opt/apps/docker/lib --insecure-registry http://10.11.150.76:5555 --registry-mirror=http://10.11.150.76:5555 -d

然后，我使用此命令创建镜像： / p>

Then, I use this command to create mirror:

docker run -d -p 5555:5000 -e STORAGE_PATH=/mirror -e STANDALONE=false -e MIRROR_SOURCE=https://registry-1.docker.io -e MIRROR_SOURCE_INDEX=https://index.docker.io -v /Users/v11/Documents/docker-mirror:/mirror  --restart=always --name mirror registry

接下来，我拉新图像，例如：

Next,I pull the new image, for example:

docker pull ubuntu

它没有工作，因为我在我的路径/ Users / v11 / Documents / docker-mirror中找不到图像。我打印镜像日志信息，它会显示错误信息：

It did't work at all, because I can't find image in my path "/Users/v11/Documents/docker-mirror". I print the mirror log information and it will show me error information:

ConnectionError：HTTPSConnectionPool（host ='index.docker.io'
port = 443）：最大重试次数超过了url：
/ v1 / repositories / library / hello-world / images（引起：[Errno 110]连接超时）

ConnectionError: HTTPSConnectionPool(host='index.docker.io', port=443): Max retries exceeded with url: /v1/repositories/library/hello-world/images (Caused by : [Errno 110] Connection timed out)

和docker log：

and docker log :

标志;只需将CA证书放在
/etc/docker/certs.d/10.11.150.76:5555/ca.crt

If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add --insecure-registry 10.11.150.76:5555 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/10.11.150.76:5555/ca.crt

我真的搜索很多相关的问题找到解决。但我还是不知道。怎么做？谢谢。

I really search many relevant questions to find solving. But I still have no idea about it. How to do it? Thanks.

推荐答案

'-registry-mirror'标志到docker已被设计为仅 工作镜像官方docker.io仓库。在2015年，他们表示注册表V2将使用'--registry-mirror'标志，但是这种功能仍然不可用。

The '--registry-mirror' flag to docker has been designed to only work for mirroring the official docker.io repository. In 2015, they said the registry V2 would be made to work with the '--registry-mirror' flag, but this capability is still unavailable.
