Expected behavior

I can run docker pull myregistry.com/image_name to pull my images

Actual behavior

I got this:

Pulling repository myregistry.com/image_name
Error while pulling image: Get http://myregistry.com/v1/repositories/image_name/images: dial tcp: lookup myregistry.com on 192.168.65.1:53: no such host

$ pinata get daemon:
{"storage-driver":"aufs","debug":true,"insecure-registries":["myregistry.com"]}

Steps to reproduce the behavior

  1. Open the VPN of my company, which I need to connect to the registry. The ip of the registry is like 172.31.12.34
  2. Set insecure-registries as How to run a insecure-registry
  3. docker pull myregistry.com/image_name

Any idea?

@tony612 What do you get if you try to curl the registry from within a container?
Something like:
docker run --rm alpine sh -c "apk add --update curl && curl http://172.31.12.34:5000/v2/"

@frenchben {}%

btw, I removed :5000 because we use port 80

Has this issue been resolved, because I am still facing it with my private v1 registry.

I am using the latest stable version of docker on mac and I still get the following error:

dial tcp: lookup private.registry on 192.168.65.1:53: no such host

Also, I did the curl test with alpine and that gave me could not resolve host error:

Couldn't resolve host 'private.registry'
