I have created a cluster of Kubernetes, and installed docker for each node.
When I try to pull or push an image to my local registry, using docker push local_registry_addr:port/image_id, I get the following response: Get local_registry_addr:port/v2: http: server gave HTTP response to HTTPS client.
This happens although I got the certificate from the registry server, and add it as a certificate on my docker server. If I try to wget local_registry_addr:port, I get 200 OK.
How can I fix it? Is there anything I need to configure perhaps?
The problem was that I wasn't suppose to add the port - using push local_registry_addr/image_id worked fine.
I created a local docker repository in my server. When I try to push the image into it, there is an error. I need an HTTPS connection. How do I get an HTTPS for my own docker registry?
os: ubuntu 16.x
Docker version: 18.06.1-ce, build e68fc7a
Already Tried:
Adding the below lines into /etc/docker/daemon.json,
{
"insecure-registries" : ["myregistrydomain.com:5000"]
}
Expected: I should be able to push and pull images into my own server containing docker registry
To avoid exposing your registry to the wider internet while still being able to pull images from it you can:
Run a local registry on your dev machine, to which you push images
ssh to your server with a reverse tunnel:
ssh -R 5000:localhost:5000 myhost
(listen on port 5000 of the remote machine (-R 5000) and tunnel back to localhost:5000 on the local machine)
Now, on myhost you can docker pull localhost:5000/someImage, but it's actually seamlessly connecting through an encrypted tunnel back to the registry on your dev machine.
You can have a local unsecured registry.
For that, you need to add an exception in your /etc/docker/daemon.json, this way
{
"insecure-registries" : ["myregistrydomain.com:5000"]
}
The same link shows how to use a self-signed certificate.
Eventually, using an actual certificate is juste a step further, but you may not need one for development purpose.
EDIT :
You need to restart your daemon after that :
service docker restart
I’ve trying to get docker working behind a corporate proxy. Following the document here:
https://docs.docker.com/config/daemon/systemd/#httphttps-proxy
Basically adding:
[Service]
Environment=“HTTP_PROXY=http://[username]:[password]#127.0.0.1:3128/”
under
/etc/systemd/system/docker.service.d/http-proxy.conf
Restart docker and all.
But when running “docker pull hello-world” or “sudo docker pull hello-world”, got this error:
centos7 ~]$ docker pull hello-world
Using default tag: latest
Trying to pull repository docker. io/library/hello-world …
Pulling repository docker. io/library/hello-world
Error while pulling image: Get https:
/index.docker.io/v1/repositories/library/hello-world/images: AuthorizedOnly
Looks around the web, but couldn’t find any “AuthorizedOnly” error reported before.
docker -v
Docker version 1.12.6, build 3e8e77d/1.12.6
Any hints/help appreciated.
Found the issue: It's not the problem with docker proxy configuration. It was the proxy itself that blocks hub.docker.com.
To resolve this particular problem, I have use a different proxy with less restrictions.
Thanks all!
Double-check your enterprise proxy URL.
Usually, an enterprise proxy does not reside on localhost (127.0.0.1), but on a specific IP address.
Usually, HTTPS_PROXY needs to be set as well (to the same HTTP URL)
Usually, NO_PROXY needs to be set, at least to localhost, to avoid contacting the proxy for every remote query.

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
Nmap scan report for google.com (216.58.223.238)

Instead something like this:

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)
