当我试图从我的本地镜像中提取一个图像时,它起作用了:
$ 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,当我想使用这个注册表作为镜像时,它就被忽略了,图像总是从web Docker中心,而不是从我的本地镜像中提取的:
$ 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**我确信它不使用我的镜像,因为当我取消代理设置时,它就无法达到hello-world映像。
是码头的窃听器,还是我漏掉了什么?

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,但解决方法不起作用:当我将--注册表-镜像=https://nexus3.pleiade.mycomp.fr:5000替换为--注册表-镜像=https://docker:password@nexus3.pleiade.mycomp.fr:5000时
我也犯了同样的错误。
如果重要的话,nexus使用的是一个自签名证书,该证书已经复制到/etc/docker/certs.d/nexus3.pleiade.mycomp.fr:5000/ca.crt,并且允许通过"docker登录“登录。

这是一个码头错误:https://github.com/docker/docker/issues/30880
解决方法是设置https反向代理,设置硬编码的身份验证头。
下面是来自费利佩C.的一个示例配置:
在nginx docker配置中,添加:
proxy_set_header Authorization "Basic a2luZzppc25ha2Vk";完整的例子:
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;

另一种方法是停靠注销其他服务器。并启用注册表配置,允许匿名停靠器拉( docker令牌域需要)。

我添加了一个/etc/docker/daemon.json:
{
"registry-mirrors": [ "nexus3.pleiade.mycomp.fr" ],
"max-concurrent-downloads": 20
