minikube can't access remote Harbor registry - kubernetes

Question

Even start minikube using minikube start --insecure-registry "<HARBOR_HOST_IP>", when tried to run a deployment yaml file which include image path like <HARBOR_HOST_IP>/app/server, got error:
Failed to pull image "[HARBOR_IP]/app/server": rpc error: code = 2 desc = Error response from daemon: {"message":"Get https://[HARBOR_IP]/v1/_ping: dial tcp [HARBOR_IP]:443: getsockopt: connection refused"}
Error syncing pod
How to set insecure-registry correctly in minikube?
Edit
Tag current docker image with 80 port:
docker tag server <HARBOR_HOST_IP>:80/app/server
Push it to Harbor registry server:
docker push <HARBOR_HOST_IP>:80/app/server
Unfortunately remote Harbor host denied:
The push refers to a repository [<HARBOR_HOST_IP>:80/app/server]

Even added <HARBOR_HOST_IP>:80 to local insecure-registries list.

Answer 1

It is working if you always define port 80 when you communicate with your docker registry which works on port 80.
Build an image:
docker build -t <REGISTRY_IP>:80/<name> <path>
Push it to registry:
docker push <REGISTRY_IP>:80/<name>
Start minikube with this insecure registry:
minikube start --insecure-registry <REGISTRY_IP>:80
Create deployment:
kubectl create -f test.yaml
where test.yaml is:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: test
spec:
template:
metadata:
labels:
app: test
spec:
containers:
- image: 192.168.1.11:80/<name>
name: test
imagePullPolicy: Always

Answer 2

Have you added secret in kubernetes?
Please refer the link to add secret: https://kubernetes.io/docs/tasks/configure-pod-container/pull-image-private-registry/
kubectl create secret docker-registry regcred --docker-server=<your-registry-server> --docker-username=<your-name> --docker-password=<your-pword> --docker-email=<your-email>
Then use the secret in kubernetes yaml.
apiVersion: v1
kind: Pod
metadata:
name: private-reg
spec:
containers:
- name: private-reg-container
image: <your-private-image>
imagePullSecrets:
- name: regcred
