推送Docker私有注册表

Question

我正在关注https://docs.docker.com/registry/deploying/并且我已经在docker.tp.cselt.it上安装了私有Docker注册表

> sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
registry            2                   65b0a3f42eef        7 days ago          165.8 MB
dockerui/dockerui   latest              95c8b9dc91e0        6 weeks ago         6.13 MB

> sudo docker ps -a
CONTAINER ID        IMAGE                      COMMAND                CREATED             STATUS                     PORTS                    NAMES

在另一台计算机上，我试图在该注册表上推送映像（hello-world）：

> docker login docker.tp.cselt.it:5000
Username (testuser):
WARNING: login credentials saved in /home/administrator/.docker/config.json
Login Succeeded

> docker pull hello-world
Using default tag: latest

> docker tag hello-world docker.tp.cselt.it:5000/hello-world

> docker images

> docker push docker.tp.cselt.it:5000/hello-world
The push refers to a repository [docker.tp.cselt.it:5000/hello-world] (len: 1)

现在，在第一台机器（docker.tp.cselt.it）上：

> sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
registry            2                   65b0a3f42eef        7 days ago          165.8 MB
dockerui/dockerui   latest              95c8b9dc91e0        6 weeks ago         6.13 MB
> sudo docker exec -it 65b0a3f42eef bash
> ls /var/lib/registry/docker/registry/v2/repositories/
  centos  hello-world  ubuntu

但是当我跑步时：

> curl -u testuser:testpassword -X GET http://docker.tp.cselt.it:5000/v2/_catalog --noproxy docker.tp.cselt.it

我收到 ””

怎么了？

里卡多

Answer 1

curl --noproxy docker.tp.cselt.it -u testuser:testpassword --insecure -X GET  https://docker.tp.cselt.it:5000/v2/_catalog
{"repositories":["hello-world"]}
