How to reach openapi interface for minikube? - kubernetes

Question

According to Kubernetes documentation, you can ping an http endpoint for a K8s cluster to operate it instead of using e.g. kubectl. It also says that there is an openApi interface available at /openapi/v2. I'm running minikube on MacOS and would like to check it out. Does anyone know if that is possible?
I tried:
minikube list service # Shows 'kubernetes' as a name
minikube list kubernetes
... which opens the browser to 127.0.0.1:51377. However, when I try going to https://127.0.0.1:51377/openapi/v2 I get the message:
{
"kind": "Status",
"apiVersion": "v1",
"metadata": {},
"status": "Failure",
"message": "forbidden: User \"system:anonymous\" cannot get path \"/openapi/v2\"",
"reason": "Forbidden",
"details": {},
"code": 403
}
... suggesting that I need some sort of authorization solution. Suggestions?

This worked for me:
# Proxy minikube to localhost on arbitrary port:
kubectl proxy --port=12345
# Now swagger.json is available at localhost:12345/openapi/v2
# Save to /tmp/temp/json and serve with e.g. docker swagger-ui container
curl localhost:12345/openapi/v2 > /tmp/temp.json
docker run -it -p 9999:8080 -e SWAGGER_JSON=/var/specs/temp.json -v /tmp/temp.json:/var/specs/temp.json swaggerapi/swagger-ui
# Open browser to localhost:9999
