Docker pull failed with request canceled while waiting for connection - docker

Question

I am trying to pull images to default docker machine. But I always get
docker#default:/etc$ docker run hellow-world
Unable to find image 'hellow-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.
docker#default:/etc$
Even if i give --dns option same error
docker#default:/etc$ docker run hellow-world --dns=8.8.8.8
Unable to find image 'hellow-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.
docker#default:/etc$
Tried adding DNS to config.json of the default machine
"EngineOptions": {
"Dns": [
"8.8.8.8",
"8.8.4.4"
]
}
resolv.conf has following entry in default machine
docker#default:/etc$
docker#default:/etc$ cat /etc/resolv.conf
search <company name>
nameserver 10.0.2.3
docker#default:/etc$
This machine sits behind the proxy and I am using kitematic for creating default machine
Kitematic is started by a custom script which will set proxies and start kitematic
Recommended and All images are displayed at the start of kitematic. But can not pull any images
Creating new machine also gives warning
PS C:\Program Files\Docker Toolbox\kitematic> docker-machine create -d virtualbox --engine-opt dns=8.8.8.8 test

Machine created with --dns option also has /etc/resolv.conf not as 8.8.8.8

PS:Issue solved after adding HTTP_PROXY to /var/lib/boot2docker/profile

Found solution
Either
add HTTP_PROXY to /var/lib/boot2docker/profile
or
create docker machine with --engine-env HTTP_PROXY=IP:PORT
