当我尝试从本地镜像中提取图像时,它可以工作:
$ docker login -u docker -p mypassword nexus3.pleiade.mycomp.fr:5000
$ docker pull nexus3.pleiade.mycomp.fr:5000/hello-world
Using default tag: latest
latest: Pulling from **hello-world**
78445dd45222: Pull complete
Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
Status: Downloaded newer image for **nexus3.pleiade.mycomp.fr:5000/hello-world:latest**
但是,当我想将此注册表用作镜像时,它只会被忽略,图像总是从Web Docker集线器中拉出,而不是从本地镜像中拉出:
$ ps -ef | grep docker
/usr/bin/dockerd -H fd:// --storage-driver=overlay2 --registry-mirror=https://nexus3.pleiade.mycomp.fr:5000
$ docker info
Registry Mirrors:
https://nexus3.pleiade.mycomp.fr:5000/
$ docker rmi nexus3.pleiade.mycomp.fr:5000/hello-world
_
$ docker pull hello-world
Using default tag: latest
latest: Pulling from **library/hello-world**
78445dd45222: Pull complete
Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
Status: Downloaded newer image for **hello-world:latest**
我肯定知道它不会使用我的镜像,因为当我取消设置代理设置时,它无法访问hello-world映像。
是Docker错误,还是我缺少某些东西?
Docker信息(简短):

更新:
在执行“ journalctl -xe”时,我可以看到一些有用的信息:
level=error msg="Attempting next endpoint for pull after error: Get https://nexus3.pleiade.mycomp.fr:5000/v2/library/hello-world/manifests/latest: no basic auth credentials"
它看起来与https://github.com/docker/docker/issues/20097有关,但是解决方法不起作用:当我替换--registry-mirror = https://nexus3.pleiade.mycomp.fr:5000时通过--registry-mirror = https:// docker :[email protected]:5000
我得到完全相同的错误。
如果有关系,则联系使用正在复制到/etc/docker/certs.d/nexus3.pleiade.mycomp.fr:5000/ca.crt的自签名证书,并且可以通过“ docker login”登录。
这是一个Docker错误:https : //github.com/docker/docker/issues/30880
解决方法是设置一个https反向代理,设置一个硬编码的身份验证标头。
这是Felipe C.的示例配置:
在nginx docker配置中,添加:
proxy_set_header Authorization "Basic a2luZzppc25ha2Vk";
完整示例:
server {
listen *:443 ssl http2;
server_name docker.domain.blah.net;
ssl on;
include ssl/domain.blah.net.conf;
# allow large uploads of files - refer to nginx documentation
client_max_body_size 0;
chunked_transfer_encoding on;
location / {
proxy_pass http://127.0.0.1:8083/;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Authorization "Basic YWRtaW46YWRtaW4xMjM=";
#proxy_set_header X-Forwarded-Proto "https";
}
}
server {
listen *:80;
server_name docker.domain.blah.net;
return 301 https://$server_name$request_uri;
}
