Installed Harbor on one host(192.168.33.10).

Installed Kubernetes cluster on other hosts.

Pushed docker images to Harbor host from client successfully. On Kubernets master host, I can also pull that image from Harbor host successfully:

$ docker pull 192.168.33.10/hello-world/hello-world
Using default tag: latest

But I created a Kubernetes deployment yaml file as:

        imagePullPolicy: Always

Then run kubectl create -f deployment.yaml

From Kubernetes dashboard it showed:

Failed to pull image "192.168.33.10/hello-world/hello-world": rpc error: code = 2 desc = Error response from daemon: {"message":"Get https://192.168.33.10/v2/: dial tcp 192.168.33.10:443: getsockopt: connection refused"}
Error syncing pod

I already set insecure-registries in /etc/docker/daemon.json:

{ "insecure-registries":["192.168.33.10"] }

How can get that from Kubernetes?

Edit

I am using Kubernetes on Rancher server cluster. Even I set Harbor server's IP, username and password, it can't access, too:
