Network timed out while trying to connect to https index docker io

Question

I’m new to docker. I was experimenting things here and there. I tried to perform docker pull hello-world but its giving me the following error

bash-3.2$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.
bash-3.2$ 

where am I going wrong?

Answer 1

This happened because docker virtual machine gets itself into a storage state. Restart your docker and then refresh the environment variables.

$ docker-machine restart default
$ eval $(docker-machine env default)

This should solve your problem..
