Good day! I have problems with configuring docker private registry. I can create a docker private registry on Linux RHEL. I configured it work as a mirror, and I can pull images from global DOCKER HUB, for Linux without a problem. But when I try to configuration this private registry work as a mirror for Windows machine. I can pull images from mcr.microsoft.com. Can anybody help me?
correct for LINUX:
version: 0.1
log:
fields:
service: registry
storage:
filesystem:
rootdirectory: /var/lib/registry
http:
addr: :5000
proxy:
remoteurl: https://registry-1.docker.io
if I change on
proxy:
remoteurl: https://mcr.microsoft.com
doesn't work.
Got it to work like this:
My config.yml is in ~/.docker/docker-registry. It looks like this:
version: 0.1
log:
fields:
service: registry
storage:
cache:
blobdescriptor: inmemory
filesystem:
rootdirectory: /var/lib/registry
http:
addr: :5000
headers:
X-Content-Type-Options: [nosniff]
health:
storagedriver:
enabled: true
interval: 10s
threshold: 3
proxy:
remoteurl: https://mcr.microsoft.com
I run the registry image like this:
docker run --restart=always -p 5000:5000 --name v2-mirror -v ~/.docker/docker-registry:/var/lib/registry --detach registry:2 serve /var/lib/registry/config.yml
In my case, the container is reachable from a windows machine at 172.16.68.1:5000.
Then I can do a docker pull 172.16.68.1:5000/windows/nanoserver:1809
Note that the "pull-through cache" feature is not available for registries other than the official docker hub, see docker doc:
It’s currently not possible to mirror another private registry. Only the central Hub can be mirrored.
