I am looking for a way to move chunk of our organization's images from Dockerhub to ECR. Is there a good way to switch between container registry services?
Thanks in advnace
I have tried creating a ECR repository and get authentication token that we can use to authenticate to an Amazon ECR registry.
Use docker tag to tag new image based on source image from Dockerhub.
Use docker push to upload it to ECR.
Does this sound right, if yes can we automate this for a chunk of images?

We've just brought Artifactory into our organization. We have a lot of Fargate stacks that are pulling the Docker images from ECR. We now want to pivot and store our Docker images in Artifactory and tell Fargate to pull the images from Artifactory.
Does anyone know how to do this?
Thanks
An Artifactory repository for Docker images is a Docker registry in every way, and one that you can access transparently with the Docker client (see documentation)
In Artifactory, start by creating a local Docker repository, then follow the "Set Me Up" instructions for that repository to upload/deploy your docker images to it.
The "Set Me Up" dialog for the Docker repository also provides the steps to have your docker clients consume/download the images from your Docker repository/registry. You would just have to replace the references of ECR with the one for your Artifactory docker repository/registry in your docker client commands.
This documentation page provides step-by-step information on how to use Artifactory as a Docker registry.
Artifactory also provides the capabilities of Remote Docker repositories, which provides proxying/caching of external registries, and Virtual Docker repositories for the aggregation of both local and remote repositories into one single entry point.
I have a task that I need to pull a Docker image from authenticated custom registry (Nexus3) to a specific repository in ECR using Bamboo. Anyone has an idea how to do? What are the flows? I have already got AWS ECR variables injecting and repository creating in ECR worked. The rest of works I am looking for a way to pull the image to the right place in ECR. Thanks in advance!
The problem is solved. We need to tag the ECR repository url to the image after pulling it from Nexus3.
I have an docker public image, Now for some reason we had to shift it to AWS ECR,Now I am able to transfer the image to ECR from docker hub, but how to make sure that all the stable release in dockerhub will be pushed to AWS ECR, I want my ECR repo update with latest dockerhub image all the time.
You might consider building and publishing your Docker image through GitHub and its CI (Continuous Integration) GitHub Actions option.
That way, you can, in your GitHub workflow, chain:
Publish-Docker-Github-Action: Publishes docker containers to DockerHub
appleboy/docker-ecr-action: Uploads Docker Image to Amazon Elastic Container Registry (ECR).
Each time you are publishing a new version of your image, it would also be available in ECR.
Using Docker Registry Sync tool, Dregsy -> https://github.com/xelalexv/dregsy
I have created docker hub repo and also created and pushed a docker image of python application to the repo.
However, I cannot find the correct Url of the image that I have to provide to the other services which will use this image. for eg azure service fabric or Kubernetes.
How can I find the exact URL? Through PowerShell or through the browser...
You don't usually download images by url. Instead, you use the docker CLI with the repository and image name.
If it's a private repo, login first, by using docker login

Use docker pull {reponame/imagename:tag} to download an image to your machine.
more about pull
Replace {reponame} with the repository name.
Replace {imagename} with the name you used with docker push.
Replace {tag} with the tag you put on the image (or latest).
For example, I use this line to get my docker hub image:
docker pull loekd/nanoserver:2.0
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.
