I'm trying (for tests purpose) to expose to kubernetes a very simple image pong http:

FROM golang:onbuild
EXPOSE 8000

I built the docker image:

docker build -t pong .

I started a private registry (with certificates):

docker run -d --restart=always --name registry -v `pwd`/certs:/certs -e REGISTRY_HTTP_ADDR=0.0.0.0:443 -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key -p 443:443 registry:2.6.2

I created a secret:

kubectl create secret docker-registry regsecret --docker-server=localhost --docker-username=johndoe --docker-password=johndoe --docker-email=johndoe@yopmail.com

I uploaded the image:

docker tag 9c0bb659fea1 localhost/pong
docker push  localhost/pong

I had an insecure registry configuration

{
  "storage-driver" : "aufs",
  "insecure-registries" : [
    "localhost"
  ],
  "debug" : true,
  "experimental" : true
}

So I tried to create my kubernetes pods with:

apiVersion: v1
kind: Pod
metadata:
  name: pong
spec:
  containers:
    - name: pong
      image: localhost/pong:latest
      imagePullPolicy: Always
  imagePullSecrets:
    - name: regsecret

I'm on MacOS with docker Version 17.12.0-ce-mac49 (21995).

If I use image: localhost/pong:latest I got:

waiting:
          message: 'rpc error: code = Unknown desc = Error response from daemon: error
            parsing HTTP 404 response body: invalid character ''d'' looking for beginning
            of value: "default backend - 404"'
          reason: ErrImagePull

I'm stuck on it since the beginning of the week, without success.
