If you are using docker-machine on a Windows or Mac computer, find the IP address of the VirtualBox VM that is. The docker command can push and pull images with Amazon ECR. The AWS CLI provides a get-login. By default, you cannot delete a repository that contains images. I have restarted docker, restarted my laptop, and tried using a different network. This started happening to me today, but I haven't tried to pull from this repo since before Dockercon (and at least 2 docker version upgrades on my laptop). I am using straight Docker for Mac, no docker-machine. I'm using the secretservice credentials helper with docker 1.11.2 and docker-compose 1.8.0-rc1. If I try to run docker-compose up, it fails to pull private images from our gitlab registry.verbose says: docker.auth.auth.resolveauthconfig: No entry found docker.api.image.pull: No auth config found Pulling the image manually using docker pull.
Docker Hub repositories allow you share container images with your team,customers, or the Docker community at large.
Docker images are pushed to Docker Hub through the
docker push
command. A single Docker Hub repository can hold many Docker images (stored astags).Creating repositories
To create a repository, sign into Docker Hub, click on Repositories thenCreate Repository:
When creating a new repository:
- You can choose to put it in your Docker IDnamespace, or in any organization where you are anowner.
- The repository name needs to be unique in that namespace, can be twoto 255 characters, and can only contain lowercase letters, numbers or
-
and_
. - The description can be up to 100 characters and is used in the searchresult.
- You can link a GitHub or Bitbucket account now, or choose to do itlater in the repository settings.
After you hit the Create button, you can start using
docker push
to pushimages to this repository.Pushing a Docker container image to Docker Hub
To push an image to Docker Hub, you must first name your local image using yourDocker Hub username and the repository name that you created through Docker Hubon the web.
You can add multiple images to a repository by adding a specific
:<tag>
tothem (for example docs/base:testing
). If it’s not specified, the tag defaultsto latest
.Name your local images using one of these methods:
- When you build them, using
docker build -t <hub-user>/<repo-name>[:<tag>]
- By re-tagging an existing local image
docker tag <existing-image> <hub-user>/<repo-name>[:<tag>]
- By using
docker commit <existing-container> <hub-user>/<repo-name>[:<tag>]
to commit changes
Now you can push this repository to the registry designated by its name or tag.
The image is then uploaded and available for use by your teammates and/orthe community.
Private repositories
Private repositories let you keep container images private, either to yourown account or within an organization or team.
To create a private repository, select Private when creating a repository:
You can also make an existing repository private by going to its Settings tab:
You get one private repository for free with your Docker Hub user account (notusable for organizations you’re a member of). If you need more privaterepositories for your user account, upgrade your Docker Hub plan from yourBilling Information page.
Once the private repository is created, you can
push
and pull
images to andfrom it using Docker.Note: You need to be signed in and have access to work with aprivate repository.
Note: Private repositories are not currently available to search throughthe top-level search or
docker search
.You can designate collaborators and manage their access to a privaterepository from that repository’s Settings page. You can also toggle therepository’s status between public and private, if you have an availablerepository slot open. Otherwise, you can upgrade yourDocker Hub plan.
Collaborators and their role
A collaborator is someone you want to give access to a private repository. Oncedesignated, they can
push
and pull
to your repositories. They are notallowed to perform any administrative tasks such as deleting the repository orchanging its status from private to public.Note:A collaborator cannot add other collaborators. Only the owner ofthe repository has administrative access.
You can also assign more granular collaborator rights (“Read”, “Write”, or“Admin”) on Docker Hub by using organizations and teams. For more informationsee the organizations documentation.
Viewing repository tags
Docker Hub’s individual repositories view shows you the available tags and thesize of the associated image. Go to the Repositories view and click on arepository to see its tags.
Image sizes are the cumulative space taken up by the image and all its parentimages. This is also the disk space used by the contents of the
.tar
filecreated when you docker save
an image.To view individual tags, click on the Tags tab.
Select a tag’s digest to view details.
Searching for Repositories
You can search the Docker Hub registry through itssearch interface or by using the command line interface. Searching can findimages by image name, username, or description:
There you can see two example results:
centos
and ansible/centos7-ansible
.The second result shows that it comes from the public repository of a user,named ansible/
, while the first result, centos
, doesn’t explicitly list arepository which means that it comes from the top-level namespace forofficial images. The /
character separatesa user’s repository from the image name.Once you’ve found the image you want, you can download it with
docker pull <imagename>
:You now have an image from which you can run containers.
Starring Repositories
Your repositories can be starred and you can star repositories in return. Starsare a way to show that you like a repository. They are also an easy way ofbookmarking your favorites.
Docker, docker, trusted, registry, accounts, plans, Dockerfile, Docker Hub, webhooks, docs, documentationSetting up your own private Docker image repository is very important for many reasons. With your private Docker image repository, you can:- Keep the images you download from Docker Hub to your private Docker image repository for future use.
- Keep the Docker custom images that you’ve built on your private Docker image repository.
- Access the private Docker image repository from any Docker server.

In this article, I am going to show you how to setup and use your own private Docker image repository. So, let’s get started.
You must have Docker installed in order to follow this article. I’ve written many articles on installing Docker in many different Linux distributions. If you’re having trouble installing Docker on your desired Linux distribution, then please read these articles at https://linuxhint.com.
If you need any further assistance in installing Docker on your desired Linux distribution, then, ask for help at https://support.linuxhint.com.
Network Topology:
This is the network topology for experimenting with Docker private image repository in this article. Here, I have 2 virtual machines (VMs) linuxhint-docker1 and linuxhint-docker2 with Docker installed. Both of these VMs are on the same network. Here, linuxhint-docker1 VM has the IP address 192.168.21.203 and DNS name docker1.linuxhint.local. I will install and configure a Docker container on the linuxhint-docker1 VM on port 5000 to be a Docker private image repository. Then, I will test the private Docker image repository by pushing and pulling Docker images from the linuxhint-docker2 VM. I will also pull Docker images uploaded to the private Docker image repository from linuxhint-docker1 VM just to verify that any Docker server on the network can use images from the configured private Docker image repository. So, let’s continue.
Setting Up a Private Docker Image Repository:
In this section, I am going to show you how to set up your own private Docker image repository. I am going to use the linuxhint-docker1 VM in this section.
First, create a directory on your computer where you want to save all the Docker images of your private Docker image repository.
Now, create a container of the registry image from the Docker Hub with the following command:
$ docker container run -d-p5000:5000--name registry -v
~/docker/registry:/var/lib/registry registry
~/docker/registry:/var/lib/registry registry
The registry container should be created. The Docker images you push to this private Docker image repository will be saved to the ~/docker/registry directory on linuxhint-docker1 VM.
Enabling insecure-registry:
You have to enable insecure registry on the Docker servers from which you want to access the Docker private image repository that you’ve created.
In this article, I want to access the Docker private image repository configured on the VM linuxhint-docker1 from the linuxhint-docker2 VM. So, on the linuxhint-docker2 VM, I have to tell Docker which insecure Docker repositories I want to use.
To do that, create a new Docker configuration file /etc/docker/daemon.json on linuxhint-docker2 VM with the following command:
Now, type in the following lines as marked in the screenshot below.
Here, I’ve added the IP address and port of the linuxhint-docker1 VM. If you have DNS configured on your network, then you can also use a DNS name here.
I have configured DNS for linuxhint-docker1 as follows via /etc/hosts file on linuxhint-docker2 VM.
As you can see, the DNS name for linuxhint-docker1 VM is docker1.linuxhint.local
So, you can add it as an insecure registry to the /etc/docker/daemon.json file as follows:
{
'insecure-registries': ['docker1.linuxhint.local:5000']
}
'insecure-registries': ['docker1.linuxhint.local:5000']
}
I’ve added both the IP address and DNS name as the insecure registry. So, the final /etc/docker/daemon.json file looks as follows:
Finally, restart the docker service on the linuxhint-docker2 VM with the following command:
Now, you can use your own private Docker image repository hosted on linuxhint-docker1 VM from linuxhint-docker2 VM.
Pushing Images to and Pulling Images from the Private Docker Image Repository:
Now, pull any Docker image from Docker Hub on linuxhint-docker2 VM. I will go for the ubuntu image in this article.
As you can see, the ubuntu image is pulled from Docker Hub.
Now, in order to push the ubuntu image to your own private Docker image repository, you have to tag the ubuntu image in a specific format.
Cannot Pull Private Repository Using Docker For Mac Download
The format is,
Here, IP is the IP address or DNS name of the VM where the private Docker image repository container is running.
PORT is the port at which the private Docker image repository container is running.
IMAGE_NAME and TAG_NAME is the name and tag of the image respectively that you want to use to identify the image. TAG_NAME is optional.
You can tag the ubuntu image using IP address as follows:
You can also tag the ubuntu image using DNS name as follows:
$ docker tag ubuntu docker1.linuxhint.local:5000/ubuntu
Now, push the tagged image to the private Docker image repository as follows:
As you can see, the image is uploaded to the private Docker image repository.
Now, I am going to remove all the cached Docker images from my linuxhint-docker2 VM.
$ docker image rm ubuntu
$ docker image rm 192.168.21.203:5000/ubuntu
$ docker image rm 192.168.21.203:5000/ubuntu
As you can see, I have no cached image in the local Docker repository.
Now, let’s try pulling the ubuntu image from the private docker image repository.
As you can see, the ubuntu image is pulled from the private Docker image repository.

The image is also cached in the local Docker image repository.
As you can see, I can also pull the images on the linuxhint-docker1 VM uploaded from the linuxhint-docker2 VM.
So, we can push and pull Docker images from our private Docker image repository.
Starting registry Container:
If you restart your Docker server where the registry container is running, then it will not automatically start on the next boot. So, the private Docker image repository will not work. But, you can easily start the registry container and get it up and running with the following command:
That’s how you set up and use your own Docker image repository. Thanks for reading this article.
