How to run or use multiple registry mirror?

Question

I know how to run a registry mirror

docker run -p 5000:5000 \
    -e STANDALONE=false \
    -e MIRROR_SOURCE=https://registry-1.docker.io \
    -e MIRROR_SOURCE_INDEX=https://index.docker.io \
    registry

and how to use it

docker --registry-mirror=http://10.0.0.2:5000 -d

But how can I use multiple registry mirror.

This is what I need:

• Docker hub mirror
• Google container registry mirror for k8s
• Private registry

So I have to make tow registry mirror and a private registry.I want to docker run registry mirror 1st and 2nd registry, and one more docker run registry hold my private registry. The client will use three of these registry.

I have no clue of how to do this,I think this is a common use case, please help, thanks.

You can use a PullSecret to tell Kubernetes what registry to get your containers from. Please see:
