'Docker Error when proxy is set : proxyconnect tcp: dial tcp: lookup http: no such host
I am facing one weird issue with docker. We have a corporate proxy and using docker on Windows server 2016.
I am trying to pull docker image from dockerhub.
Started facing this issue recently. It was working fine earlier.
Steps
1) Set HTTP and HTTPS Proxy
2) Executed docker pull hello-world:nanoserver
Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: dial tcp: lookup http: no such host
Any idea whats going wrong here. I have couple of other machines having same setting and works fine.
Update 1: 06/03/2019
I did some trial and error and found that docker version is the culprit here.
I installed docker 17.06.2-ee-17, 17.06.2-ee-16 and tried pulling image. It worked fine.
So now question is what is wrong with latest 3 versions of docker ee for windows. i.e 17.06.2-ee-18,17.06.2-ee-19,17.06.2-ee-20 which is giving me this error.
Solution 1:[1]
We had exactly the same issues.
It appears to work in the newer versions when we used the fully qualified version of our proxy server.
i.e. http://proxy-server.my-domain.net:8080
instead of http://proxy-server:8080

Sorry, My answer is for Linux ("Error response from daemon: Get https://registry-1.docker.io/v2/:Proxyconnect tcp: dial tcp:lookup proxy.example.com:no such host")
Firsty check docker version with this command ($docker -v )
Output: Docker version 19.03.10, build 9424aeaee9 (Can be any version)
Check Can you ping to google ($ping google.com )
If it work, dont need to fix the file (/etc/hosts and /etc/resolv.conf)
$sudo snap install docker
Then check PATH environment variable
$echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin ( Output must be like this)
The output doesn't include /snap/bin path. You can define with below command
$export -n PATH=$PATH:/snap/bin
$echo $PATH ( check with this command )
Now login to docker hub
$docker login
When login succeeded,can pull any images from docker hub
$docker pull hello-world
