Docker: can't run hello-world. Windows 10 - docker

I'm a newbie in docker. I try to run
$ docker run hello-world
And I got this error:
$ docker run hello-world
Unable to find image 'hello-world:latest' locally
Pulling repository docker.io/library/hello-world
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: 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..
See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.
Also I allowed all points for this app in firewall

I ran into that issue while moving from mac to windows. I would recommend to check the following things:
How many network adapters do you have? Check if there are too many and if docker is using the correct one. In case you have too many - delete the one which is not being used
for some people the network protocol IP6 needed to be deactivated to get docker to talk to the internet
check your traffic on the network adapter - in case you are using hyper-v you need to make sure that the network adapter is allowed to use the one which is connected to the internet
I hope this gave you a notch into the right direction.

I resolved this issue on windows 10 by resetting the DNS server to use the Google DNS fixed address: 8.8.8.8 (docker documentation)

After installing the docker for windows, I got the error as below.
PS C:\Users<Username>> docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled (Client.Timeout exceeded while awaiting headers).
So made changes in docker > Settings > Resources > Network > updated docker subnet to
10.0.75.0/24.
It worked like charm after.

podman wsl communication issue

I am switching from docker to podman currently. Usually that works just fine. However on one of my many company laptops I ran into the following error:
PS C:\WINDOWS\system32> podman pull quay.io/podman/hello
Trying to pull quay.io/podman/hello:latest...
Error: initializing source docker://quay.io/podman/hello:latest: pinging container registry quay.io: Get "https://quay.io/v2/": dial tcp 54.163.152.191:443: i/o timeout
The above error I also get with other container registries. I tried:
Tried:
podman machine set --rootful
removing hyper-v and wsl
changing resolv.conf and adding nameserver
(tried also 8.8.8.8)
looked into symantec endpoint protection logs
(connection is not blocked)
switched between wsl 1 and 2
also tried some stuff from this thread (cf. No internet connection on WSL Ubuntu (Windows Subsystem for Linux))
I also do not get any internet inside e.g. an Ubuntu WSL VM. In Powershell running e.g. curl google.com works just fine
For completeness sake with the third option changes I get:
podman pull quay.io/podman/hello
Trying to pull quay.io/podman/hello:latest...
Error: initializing source docker://quay.io/podman/hello:latest: pinging container registry quay.io: Get "https://quay.io/v2/": dial tcp: lookup quay.io: Temporary failure in name resolution
Update:
I reinstalled Docker and get a similar issue
docker container run hello-world
Unable to find image 'hello-world:latest' locally
docker: initializing source docker://hello-world:latest: pinging container registry registry-1.docker.io: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io: Temporary failure in name resolution.

I was facing the same error Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: TLS handshake timeout because of slow internet connection.
Switching to a comparatively faster internet connection didn't fix my problem at first. Then I restarted docker and it worked.
$ sudo systemctl restart docker
The reason is the network policy in my area.You can change your mirror address and try, in my cases, I changed the mirror address and works.I am using macOS Catalina:
"registry-mirrors" : [
"https://dockerhub.azk8s.cn"
]
Hope this help you.
This most of the times happens when my internet connection is slow. Please check your internet connection and retry.
Try switching your internet connection.
If you are connected via WiFi try connecting with LAN.
Put debug: true under the docker-engine tab and restart the docker. This worked for me on MAC M1.
I was having same issue. It was fixed by resetting demon settings on Docker Desktop macOS Catalina. I hope It will work for you .
Possible Solutions
Check internet speed and connect to Faster Internet
Restart Docker
Reset Demon Settings
If your region is restricted by the Docker server's use proxy.
On windows, try restarting the docker daemon.
Then log in with your docker Id docker login in your terminal...
Worked for me.
On rhel, try
# docker login
Login with your Docker ID to push and pull images from Docker Hub.
If you don't have a Docker ID, head over to https://hub.docker.com to create one.
Username: xxxx
Password: xxxx
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
It works fine.
sometimes you can pull a lot of images, normally you can pull 200 images for free every 6 hours
Don't ask me why this connection,
I think docker needs a connection for that.
Below steps Worked for me on mac Ventura 13.1:
Clean / Purge data — from Docker Dashboard
Reset to factory defaults — From docker dashboard
Restart Docker Desktop — from docker dashboard
In my case, there is an entry in the /etc/hosts which needs to be removed as it was pointing to wrong docker.io entry always.
Its silly though, took sometime to figure out it.

I have looked for a solution that says to set proxy, but I have set the proxy for the wifi.
https://docs.docker.com/docker-for-mac/networking/#httphttps-proxy-support
Still, it is not working.
I have set proxy for docker too. It is not working.
in Preference -> proxies
Docker version 17.12 ce
I also want to know if the proxy is the issue then how can I check it is set, what is work around for this?
Here are few suggestions:
Try restarting your Docker service.
Check your network connections. For example by the following shell commands:
</dev/tcp/registry-1.docker.io/443 && echo Works || echo Problem
curl https://registry-1.docker.io/v2/ && echo Works || echo Problem
Check your proxy settings (e.g. in /etc/default/docker).
If above won't help, this could be a temporary issue with the Docker services (as per Service Unavailable).
Related: GH-842 - 503 Service Unavailable at http://hub.docker.com.
I had this problem for past days, it just worked after that.
You can consider raising the issue at docker/hub-feedback repo, check at, Docker Community Forums, or contact Docker Support directly.
docker logout
docker login
This might solve your problem
I tried running on Windows, and got this problem after an update. I tried restarting the docker service as well as my pc, but nothing worked.
When running:
curl https://registry-1.docker.io/v2/ && echo Works
I got back:
{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":null}]}
Works
Eventually, I tried:
https://github.com/moby/moby/issues/22635#issuecomment-284956961
By changing the fixed address to 8.8.8.8:
Which worked for me!
I still got the unauthorized message for curl https://registry-1.docker.io/v2/ but I managed to pull images from docker hub.
For me I had this issue when I first installed Docker and ran
docker run hello-world
I got an authentication required error when I ran
curl https://registry-1.docker.io/v2/ && echo Works
All I needed to do was to restart my MacOS and then run the command again, it just started pulling the image and i got the message
Hello from Docker!
This message shows that your installation appears to be working correctly.
It's clearly a proxy issue: docker proxies https connections to the wrong place. Bear in mind that docker proxy settings may be different from the operating system (and curl) ones. Here's how I managed to solve the issue:
First of all, find out where are you proxying your docker https requests:
# docker info | grep Proxy
Http Proxy: http://<my.proxy.server>:8080
Https Proxy: https://<my.proxy.server>:8080
No Proxy: localhost,127.0.0.1
and double check your https settings.
In my case, I realized that the "Https proxy" was set to https://... instead of http://..., so I corrected it in /etc/sysconfig/docker file (I'm using RHEL7) and, after a docker restart with:
# systemctl restart docker
the proxy variable shows up succesfully updated:
# docker info | grep Proxy
Http Proxy: http://<my.proxy.server>:8080
Https Proxy: http://<my.proxy.server>:8080
No Proxy: localhost,127.0.0.1
and everything works fine :-)
Just to add, in case anyone else comes across this issue.
On a Mac
I had to logout and log back in.
docker logout
docker login
Then it prompts for username (NOTE: Not email) and password. (Need an account on https://hub.docker.com to pull images down)
Then it worked for me.
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
For me the problem was solved by restarting the docker daemon:
sudo systemctl restart docker
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
try to reload daemon then restart docker service.
systemctl daemon-reload
I had this same issue when working on an Ubuntu server.
I was getting the following error:
deploy#my-comp:~$ docker login -u my-username -p my-password
WARNING! Using --password via the CLI is insecure. Use --password-stdin.
Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp 35.175.83.85:443: connect: connection refused
Here are the things I tried that did not work:
Restarting the docker service using sudo docker systemctl restart docker
Powering off and restarting the Ubuntu server.
Changing the name server to 8.8.8.8 in the /etc/resolv.conf file
Here's what worked for me:
I tried checking if the server has access to the internet using the following netcat command:
nc -vz google.com 443
And it returned this output:
nc: connect to google.com port 443 (tcp) failed: Connection refused
nc: connect to google.com port 443 (tcp) failed: Network is unreachable
Instead of something like this:
Ncat: Version 7.70 ( https://nmap.org/ncat )
Ncat: Connected to 172.217.166.110:443.
Ncat: 0 bytes sent, 0 bytes received in 0.07 seconds.
I tried checking again if the server has access to the internet using the following wget command:
wget -q --spider http://google.com ; echo $?
And it returned:
4
Instead of:
0
Note: Anything other than 0 in the output means your system is not connected to the internet
I then tried the last time if the server has access to the internet using the following Nmap command:
nmap -p 443 google.com
And it returned:
Starting Nmap 7.01 ( https://nmap.org ) at 2021-02-16 11:50 WAT

All this was enough to make me realize that connections to the internet were not allowed on the server.
All I had to do was speak with the team in charge of infrastructure to fix the network connectivity issue to the internet on the server. And once that was fixed my docker command started working fine.
Resources: 9 commands to check if connected to internet with shell script examples
That's all.
I hope this helps
Recheck Proxy Settings with the following commands
docker info | grep Proxy
Check VPN Connectivity
If VPN not using CHECK NET connectivity
Reinstall Docker and repeat the above steps.
Enjoy
On my windows 11 all I did was to first login into my account
docker login
Got this from a network filter (LuLu on macOS) blocking traffic to/from Docker-related processes.
I had this issue when I first installed Docker and ran
docker run hello-world
I was on a corporate network and switching to my personal network solved the issue for me.
The answers are provided here amazing, but if you are new in that and you don't realize full error then you may see at the end of that error net/http: TLS handshake timeout. message means that you have a slow internet connection. So it can be only that problem that's it.
Toodles
I had the following entries in my /etc/hosts file:
34.228.211.243 registry-1.docker.io
34.205.88.205 auth.docker.io
104.18.121.25 production.cloudflare.docker.com
Just by commenting them out, I fixed the problem.
List item
Many good answers above, but mine is a bit different with Mac and Docker Desktop UI. In my case, it is a Desktop proxy setting that needs to be turned off when I am outside of corporate fiewall/proxy:
ERROR message from docker CLI:
Username: xxx
Password: ***
Error response from daemon: Get https://registry-1.docker.io/v2/: Service Unavailable
My env: Machine Mac with Docker UI (i.e. called Docker Desktop,
shown as a whale icon), running outside of corp firewall/proxy.
I am able to Sign In with Docker Desktop UI.
However, whether docker login or docker pull, I kept getting the above error and I got sidetrack into the user id, reset the daemon, ...
Finally, I got to the Docker Desktop UI. Sure enough, there is a proxy setting that I have setup long time ago, and totally forgot about it!
Yes, when I am outside of firewall, I need to turn off the proxy setting here.
Docker Desktop -> Preference -> Resources -> Proxies. Turn
Turn off the manual proxy configuration.
Then docker pull works (without docker login as I was pulling a public image)!
Thanks
PS. I think the difference in behavior of Docker Desktop and Docker CLI contributes to the confusion. I am able to login to docker through the GUI, and the CLI keeps erroring out without good enough diagnostic information.
Using Linux. For me it worked by doing:
$ docker logout
log out of hub.docker.com
log in to hub.docker.com
$ docker login
Check whether containers is enabled or not?
Goto --> turn on/off windows feature, then enable checkbox of containers
Restart windows.
Using the root account instead of my regular user account solved it for me.
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.
In my case, stopping Proxifier fixed it. I added a rule to route any connections from vpnkit.exe as Direct and it now works.
One of the problems you might need to check is,
Does the registry requires VPN,
Enable your VPN and try pulling again.
Thanks.
Ok, I have a similar issue and nothing seemed to help, restart docker, disabled IPv6 and the nslookup and dig all seemed fine.
What worked for me was going to my Docker Desktop -> Preferences -> Experimental Features and unchecking Use new virtualization framework.
docker login terminal command worked for me.
If your machine requires VPN then must connect with VPN first and try docker login.
Have you create a repo with the matching tag on destinated docker hub? It might be that your container image has no where to be pushed to.
Run export DOCKER_CONTENT_TRUST=0 and then try it again.
Use --tls in the pull request.
For example if original pull request is docker pull dgraph/dgraph:v21.03.0
Use this instead : docker --tls pull dgraph/dgraph:v21.03.0
Just reloading system, this is helped for me. (Windows 10 64x)

Docker for Windows: error pulling image configuration: i/o timeout

I have installed the latest version of Docker for Windows (1.12.1-stable, build 7135) on my Windows 10 Pro-64 bit. I was able to successfully execute docker run hello-world. However, when I do docker run busybox, an error is thrown as below.

See 'docker run --help'.
The same error occurs for several other images. I do not have a proxy and have a stable internet connection. I have tried this with windows firewall enabled and disabled. I have also restarted the docker service.
Let me know if I am missing something. Thanks in advance.
This is a known issue with the networking stack in the current version of Docker for Windows.
The workaround is detailed in remove stale network adapters: open the Network settings in Docker for Windows, and select the 'Fixed' DNS setting, using Google's DNS server 8.8.8.8.
I was also facing the similar issue while running Docker on Windows 10.
The issue got resolved by changing the DNS settings.
(Settings -> Network -> DNS Server -> 8.8.8.8 ( Automatic)
I observed that when the DNS server option was set to manual, the timeout issue still remains.
After making these changes, Docker service was restarted and I was able to pull the Docker image successfully.
regards,
dattatray.
Simply setting the DNS to fixed (and setting the target to 8.8.8.8) fixed it for me (after Docker restarted).
0
Setting up proxies and changing stale DNS settings were of no use in my case.
I had to reset the Virtual machine using below steps in docker-toolbox bash:
Stop the host docker virtual machine:
$ docker-machine stop default
Delete the host:
$ docker-machine rm default
Create new VirtualBox machine named default:
$ docker-machine create --driver virtualbox default
Verify if the machine is runnning. ACTIVE attribute should be marked *:
$ docker-machine ls
If the machine is not running, run the machine:
$ docker-machine run default
Then, on docker run mysql:8.0, you will get below screen in your bash
Hope it help you guys and save your time!

When I execute the simple command like the one below, I get the error that prevents images being pulled. Any help here ?
Even when I changes the dns nameserver ( in /etc/resolv.conf) to 8.8.8.8 , I have the same issue.
I looked at other issues posted on same subject . Did not get any help .
