I want to use local registery for my kubernetes. I can use How to access private Docker Hub repository from Kubernetes on Vagrant and it works i can pull my image from it but i should use
image: IP_OF_DOCKER_REGISTERY:5000/IMAGE_NAME
But i do not want it. i want to every image pull form my docker registery without assign any IP and port.
What should i do?
How can i use proxy?
What you're asking is not possible out-of-the-box with docker, if you want to use a registry different to Docker hub, you have to specify it as stated in the documentation.
$ docker pull <private_registry>/image_name:tag

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.
The official doc provides a way to run docker registry on containers, but given the situation that it is not allowed to run the registry in the container, how to start docker-registry without docker?
There are multiple options. You can use one of the following repository manager to easily setup a docker private registry and use that.
Sonatype nexus
GitLab container registry
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'm just curious if there's a chance to move out the gitlab registry to a different host? I can see, that it is possible to move the storage to another place, but what about the service itself?
I just want to run the registry on another place but want to make use of the authentication and the UI features of gitlab to manage it. May be this is not possible, but please someone shed some light on it.
Yup, you can disable the bundled registry and run a registry yourself, while still using GitLab's authentication and UI.
GitLab's built-in registry is basically just a deployment of the Docker Registry. You can run it, or another compatible registry, and then configure GitLab to use it as described here: Disable Container Registry but use GitLab as an auth endpoint.
I have docker machine and by default it pulls my images from docker hub.
Now we have our own repo which can serve as a remote proxy to docker hub.
We can pull with docker pull server/repo/image.
Now I want that docker pull image resolves to our registry instead of docker hub. How can I achieve this in docker machine?
Changing the default docker registry is not possible. You can only configure a private registry to act as a mirror for the dockerhub registry as documented in Registry as a pull through cache.
Check moby-33069 issue which has requested this feature.
It can be done if you're using the Red Hat fork of Docker which is in their repo's, CentOS or EPEL not sure.
You use the --add-repository flag.
If I'm not mistaken you can also change the default repo if you build from source.
