将不安全的注册表添加到Docker [英] Add Insecure Registry to Docker

问题描述

我有一个在CentOS上运行的docker 1.12。我正在尝试向其中添加不安全的注册表，并且文档中提到的内容无法正常工作。系统使用 systemd ，所以我创建了 /etc/systemd/system/docker.service.d/50-insecure-registry.conf 文件。

I have a docker 1.12 running on CentOS. I am trying to add insecure registry to it and things mentioned in documentation just don't work. The system uses systemd so I created a /etc/systemd/system/docker.service.d/50-insecure-registry.conf file.

$ cat /etc/systemd/system/docker.service.d/50-insecure-registry.conf
[Service]
Environment='DOCKER_OPTS=--insecure-registry="hostname.cloudapp.net:5000"'

在加载守护程序并重新启动docker服务后，systemd显示环境变量存在

After loading daemon and restarting docker service, systemd shows that the environment variable is there

$ sudo systemctl show docker | grep Env
Environment=DOCKER_OPTS=--insecure-registry="hostname.cloudapp.net:5000"

但是当我运行 docker info 时，我看不到添加了不安全的注册表

But when I run docker info I don't see that insecure registry added

$ docker info
........
Registry: https://index.docker.io/v1/
WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled
Insecure Registries:
    127.0.0.0/8

将图像推送到 hostaneme.cloudapp.net 失败，

Pushing application     (hostname.cloudapp.net:5000/application:latest)...
The push refers to a repository     [hostname.cloudapp.net:5000/mozart_application]
ERROR: Get https://hostname.cloudapp.net:5000/v1/_ping: http: server gave HTTP response to HTTPS client

有什么可以做的吗？我想念什么吗？

Is there something that could be done ? Am I missing something ?

更新

通过添加文件 /etc/docker/daemon.json 具有以下内容

Resolved the issue by adding a file /etc/docker/daemon.json with following content

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

然后重新启动docker

And then restart docker

sudo systemctl daemon-reload
sudo systemctl restart docker

在该不安全的注册表 hostname.cloudapp.net:500 起作用之后。

After that insecure registry hostname.cloudapp.net:500 works.

推荐答案

（从问题中复制答案）

要添加不安全的Docker注册表，请添加文件 /etc/docker/daemon.json 具有以下内容：

To add an insecure docker registry, add the file /etc/docker/daemon.json with the following content:

{
    "insecure-registries" : [ "hostname.cloudapp.net:5000" ]
}

，然后重新启动docker。

and then restart docker.
