Every answer helps , so share how you solve that .

Answer 1

I have solved this issue about $ sudo docker run hello-world following the Docker doc.

If you are behind an HTTP Proxy server of corporate, this may solve your problem.

Docker doc also displays other situation about HTTP proxy setting.

Answer 2

For me the problem was solved by restarting the docker daemon:

sudo systemctl restart docker

Answer 3

One option which worked for me on MAC.

Click on the Docker Icon in the tray. Open Preferences -> Proxies. Click on Manual Proxy and specify Web Server (HTTP) proxy and Secure Web server (HTTPS) proxy in the same format as we specify in HTTPS_PROXY env variable. Choose Apply and Restart.

This Worked for me

Answer 4

Run export DOCKER_CONTENT_TRUST=0 and then try it again.

Answer 5

Got this from a network filter (LuLu on macOS) blocking traffic to/from Docker-related processes.

Answer 6

NTML PROXY AND DOCKER 

If your company is behind MS Proxy Server that using the proprietary NTLM protocol.

You need to install **Cntlm** Authentication Proxy

After this SET the proxy in 
/etc/systemd/system/docker.service.d/http-proxy.conf) with the following format:

[Service]

Environment=“HTTP_PROXY=http://<<IP OF CNTLM Proxy Server>>:3182”

In addition you can set in the .DockerFile
export http_proxy=http://<<IP OF CNTLM Proxy Server>>:3182
export https_proxy=http://<IP OF CNTLM Proxy Server>>:3182
export no_proxy=localhost,127.0.0.1,10.0.2.*

Followed by:
systemctl daemon-reload

systemctl restart docker

This Worked for me
