I've followed this docs manual to create a self-signed private registry on some VM. It works fine when I pull images from another host.
I now try to understand how I configure a Service Connection in Azure DevOps of type Docker Registry to use this registry.
This is my current setup:
And this is the log:
We could go to the Docker's Settings > Network and change DNS Server radio button to Fixed
In addition, I found a sample issue, you could also check this.

I’m trying to deploy a docker image on a kubernetes cluster. This cluster is on a server accessible via a ssh connection.
Here is the part of the .yaml I use to pull the image :
spec :
containers :
- name : my_image_name
image : my_private_registry/my_image
my_image is stored in a private registry in another server accessible via a ssh connection (with a proxyjump).
I know how to pull an image from a private registry that is on the same server that the kubernetes cluster. But when it is on another server, I don’t. I'm sure that it is possible to configure kubernetes to make it use the ssh connection, but I didn't find ressources helping me to do that. The others private registry are accessible just by a "docker login" command ?
I’ve found a beginning of solution sending the image using a package named « docker_over_ssh », but it was not really appropriate. I’ve found a solution by pushing the image on dockerhub, but I’m sure that we can do better …
Thank you for your help. I’m sure that it is not complicated, but I’m quite new in kubernetes and docker.
It is quite important to understand, that the docker daemon does not run inside kubernetes. So whatever you provide through kubernetes objects (pods, services...) is usually not accessible from outside.
You could provide a mirror registry for your cluster, so that it is accessible in the usual way.
Another option would be to use ssh port forwarding, if the ssh proxy allows that and use the forwarding host as registry.
I am using Azure Kubernetes Service(AKS) and I am no allowed to use Docker Hub repository for pushing and pulling Images, so please tell me, is there a way to create kubernetes deployments or pods by using tar of image or by pulling image using ssh connection from other server in which I am having Docker engine running.
I am assuming that the reason why you are not allowed to use Docker Hub is because of the company policy that wants to keep everything private and contained within Azure.
In that case, I suggest using the Azure's own container registry service named Azure Container Registry which have the following benefit:
It works similar to DockerHub in the sense that you can just sign in with username and password, update the image name and you are good to go.
It is the solution from Azure which should fit nicely in your Infrastructure design. Please refer to this link for details instructions on how to connect your AKS and ACR.
The traffic flow from AKS and ACR is private and not exposed to the Internet.
I'm messing around with Artifactory and have used the artififactory-pro docker container to get me up and running on an azure vm. I'm now trying to push a docker image to the docker-local repository within Artifactory. This is working locally but I had to change my local docker options to include the insecure-registry I set up.
To continue my POC further I want to be able to push to the artifactory docker repo using the MS hosted 'ubuntu-latest' agent with Azure pipelines but I believe I need to set the docker options on the agent to again allow the insecure regsitry as it's currently throwing the error:
[Error] Docker login failed for: http:/, http:.
How do I set the docker options on the MS hosted agent within my pipeline? I'm having to install .net-core 3.1 sdk during the pipeline so i'd like to think it is possible.
Thanks
As far as I know, you cannot set docker options to allow insecure regsitry on MS hosted agent. To set insecure registry, you have to modify some docker config file. But we are restricted to modify the system files of MS hosted agent for security reason, you will get access denied error if you try to do so.
The workaround is to create your own self-hosted agent on your local machine. So that you can set the insecure registry for docker daemon on local machine.
However you can also submit a feature request(click suggest a feature and choose azure devops) to Microsoft Development team. Hope they will consider implementing a feature to enable seting docker options on MS hosted agent.
I'm novice in docker and I would like to deploy a docker private registry on my host (Windows10 usign docker for windows) with users permissions so I used TLS to securite it according to the doc from https://docs.docker.com/registry/deploying/
I have the docker private registry deployed and to push the user must do docker login command.
Now, I would like to connect a UI to my private registry and make it read only to be able to pull and for that I tried to setup Harbor, Portus and many other examples but they are not documented for windows.
I tried to use this project https://github.com/kwk/docker-registry-frontend but same thing.
All of these projects they bind files in volumes docker run -v pathToFiles:pathToFiles:ro but in windows it is not supported.
I tries to make modification in images and put the files into them and build a new images with docker commit but the UI still not work or not connected to my server.
So, what is the best way to deploy a docker private registry with the docker registry open source in docker for windows AND manage user permissions with auth ? Should I use a reverse proxy ? but how on windows?
I'm not using docker EE.
Thank you.
I am trying to use Jenkins to build and push docker images to private registry. However, while trying docker login command, I am getting this error:
http: server gave HTTP response to HTTPS client
I know that this might be happening because the private registry is not added as an insecure registry. But, how I can resolve this in CI pipeline?
Jenkins is set up on a Kubernetes cluster and I am trying to automate the deployment of an application on the cluster.
This has nothing to do with the Jenkins CI pipeline or Kubernetes. Jenkins will not be able to push your images until configure follow either of the below steps
You have two options here
1) Configure your docker client to use the secure registry over HTTPS. This will include setting up self signed certificates or getting certificates from your local certificate authority.
2) Second solution is to use your registry over an unencrypted HTTP connection.
So if you are running docker on kubernetes. You will have to configure the daemon.json file in /etc/docker/daemon.json.
PS: This file might not exist. You will have to create it.
Then add in the below content. Make sure you change the url to match your docker registry
{
"insecure-registries" : ["myregistrydomain.com:5000"]
}
Then restart docker using systemctl restart docker or etc/init.d/docker restart depending on the version of linux distro installed on your cluster
Let me know if you have any questions
