We need to pull all our base images form a private docker registry. Is pulling the image from
docker hub and pushing it to the private registry the only option to achieve the above requirement.

You need to use docker login to log into your private registry before you execute docker pull\push commands
Also how to pass credentials of my private registry and tell my Dockerfile to pull from the private registry instead of the docker hub
The registry's address is to be specified in the image tag name as exampled here:
docker tag nginx myregistry.azurecr.io/samples/nginx

I have a private registry at the url registry.lab.example.com where I can push images to from my master node in ocp cluster. When I go about launching a new app referring an image from this private registry, the lookup fails with a error message that the image is not found.
oc new-app --docker-image=registry.lab.example.com/openshift/nginx
My private registry is not even polled to look for the images and that'y why the deployment fails. Is there a way I can add this private registry in the list of to be searched repositories when docker tries to find an image?
There's --add-registry option for docker daemon in RHEL's docker branch (see registry-externally-accessible, check if it's fit to your environment). In addition, you can configure the registry a primary docker source (see pull-through-cache).
Expand RED HAT CONTAINER REGISTRY with a local Docker image repository.
As a Docker user, I can work with the registry (pull, push) everything is OK!
But also, as a user, I can upload an image with the docker hub with the pull command.
For example:
$ docker pull debian
Question:
How to prevent the user to "pull" the image with docker hub and allow using only the openshift internal registry?
Those. Is it possible to configure any config so that the user accesses the internal repository of images?
Is there anyway to proxy or mirror the following Docker registries with my own Private Docker Registry?
Google Container Registry
AWS EC2 Container Registry
Azure Container Registry
Quay.io
DockerHub
I want to use a Private Registry to store all Docker Images I need.
I want to pull Images without changing the repo/image:tag name when doing a docker pull? For example, with Nexus if I want to do a:
docker pull gcr.io/google_containers/metrics-server-amd64:v0.2.1
I must change the repo name:
docker pull mynexus.mycompany.com/google_containers/metrics-server-amd64:v0.2.1
Is there any docker/kubernetes config that says if someeone does a pull if a gcr.io Image just go to mynexus.mycompany.com instead and use as a pass thru cache.
GCR, ECR, ACR and Quay.io not supported current docker
Try this proxy
https://github.com/rpardini/docker-registry-proxy
https://github.com/rpardini/docker-caching-proxy-multiple-private
In Sonatype Nexus,
create a "docker (proxy)" repository.
create a "docker (group)" repository.
In the group, repository, add both the proxy and any hosted repos
You should now be able to refer to the group repository URL, qualified with your image names and tags, to retrieve any image in any repository that the group can see. You will need to set-up individual proxies for each of GCR, Quay, etc. Also, your image build processes will need to push to the one of your hosted repositories, NOT to the group repository. You push to your hosted, and pull from your group.
I'm using docker-compose command to run multiple containers. The problem is my docker-compose has to pull some images from the public repository and some from a private repository. What I'm planning to do is push all required images to the private repository but how can I make docker-compose pull the images from the private repository.
In short -> How to point to a private repository when the images are only available there
Use docker login command. (Official doc)
Enter your credentials, and then you can pull private image, only if you have an access.
If you want to login to a self-hosted registry you can specify this by adding the server name.
docker login localhost:8080
Thanks to #herm's comment, if you want to use swarm, use :
--with-registry-auth option.
Personnaly, I use this command :
docker stack deploy --with-registry-auth --compose-file dev.compose.yml myProjectName
I have a new machine with a docker engine. I want to pull down a private docker image from docker.com.
I can pull down any public docker image, no problem.
klas#dockerengine:~$ docker pull nginx
latest: Pulling from nginx
39bb80489af7: Pull complete
df2a0347c9d0: Pull complete
[...]
But my private image fails:
klas#dockerengine:~$ docker pull mellbourn/privaterepo
Pulling repository mellbourn/privaterepo
FATA[0002] Error: image mellbourn/privaterepo:latest not found
What should I do?
It may have to do with SSH, but I know very little about SSH.
You need to run docker login before you can access private repositories.
