Docker：通过ip地址参考注册表 [英] Docker: Refer to registry by ip address

问题描述

我有一个Docker镜像，我想推送到我的注册表（托管在 localhost ）。我做：

I have a Docker image I want to push to my registry (hosted on localhost). I do:

docker push localhost:5000/my_image

并正常工作。但是，如果我标记图像并推送它：

and works properly. However, if I tag the image and push it by:

docker push 172.20.20.20:5000/my_image

我收到错误。

推送是指存储库[172.20.20.20:5000/my_tomcat]（len：1） code>

无法ping注册表端点https://172.20.20.20:5000/v0/ v2

ping尝试失败并出现错误：

获取https://172.20.20.20:5000/v2/：网关超时

我不能通过IP引用注册表？如果是这样的话，我该怎么把另一个主机的图像推送出去？ localhost ？

Can't I refer to registry by IP? If so, how could I push an image from another host that it is not localhost?

编辑

我以这种方式运行注册表：

I'm running the registry this way:

docker run -d -p 5000:5000 --restart=always --name registry registry:2

推荐答案

如所有事情的知识产权（通过 Jess Frazelle ），您应该能够使用docker 1.10，以固定的IP地址运行注册表。

As mentioned in "IPs for all the Things" (by Jess Frazelle), you should be able, with docker 1.10, to run your registry with a fixed IP address.

它使用 - net = --ip = 码头运行选项。

It uses the --net= --ip= options of docker run.

# create a new bridge network with your subnet and gateway for your ip block
$ docker network create --subnet 203.0.113.0/24 --gateway 203.0.113.254 iptastic

# run a nginx container with a specific ip in that block
$ docker run --rm -it --net iptastic --ip 203.0.113.2 nginx

# curl the ip from any other place (assuming this is a public ip block duh)
$ curl 203.0.113.2

您可以将此示例调整为注册表Docker运行参数。

You can adapt this example to your registry docker run parameters.
