Docker Push and Pull

Docker is a new approach in application packaging and deployment in many ways. Some quite disturbing paradigms are therefore considered:

Push the image

  • Open the Launchpad and locate the Docker Quickstart Terminal icon.
  • Click the icon to launch a Docker Quickstart Terminal.
  • Place your cursor at the prompt in the Docker Quickstart Terminal window.
  • Type docker images to list the images you currently have:


Find the IMAGE ID for your docker-whale image.

In this example, the id is 7d9495d03763.

Note: The REPOSITORY shows the repo name docker-whale but not the namespace. You need to include the namespace for Docker Hub to associate it with your account.

The namespace is the same as your Docker Hub account name. You need to rename the image to YOUR_DOCKERHUB_NAME/docker-whale.

Use IMAGE ID and the docker tag command to tag your docker-whale image.

The command you type looks like this:


Your account name will be your own. So, you type the command with your image’s ID and your account name and press RETURN.

$ docker tag 7d9495d03763 maryatdocker/docker-whale:latest

Type the docker images command again to see your newly tagged image.


Use the docker login command to log into the Docker Hub from the command line.

The format for the login command is:

docker login –username=yourhubusername –email=youremail@company.com

When prompted, enter your password and press enter. So, for example:

$ docker login –username=maryatdocker –email=mary@docker.com
WARNING: login credentials saved in C:\Users\sven\.docker\config.json
Login Succeeded

Type the docker push command to push your image to your new repository.

$ docker push maryatdocker/docker-whale

The push refers to a repository [maryatdocker/docker-whale] (len: 1)

Return to your profile on Docker Hub to see your new image.

Pull the image

Pull the image you just pushed to hub. Before you do that you’ll need to remove the original image from your local machine. If you left the original image on your machine. Docker would not pull from the hub — why would it? The two images are identical.

Place your cursor at the prompt in the Docker Quickstart Terminal window.

Type docker images to list the images you currently have on your local machine.


To make a good test, you need to remove the maryatdocker/docker-whale and docker-whale images from your local system. Removing them forces the next docker pull to get the image from your repository.

Use the docker rmi to remove the maryatdocker/docker-whale and docker-whale images.

You can use an ID or the name to remove an image.

$ docker rmi -f 7d9495d03763

$ docker rmi -f docker-whale

Pull and load a new image from your repository using the docker run command.

The command you type should include your username from Docker Hub.

docker run yourusername/docker-whale

$ docker run maryatdocker/docker-whale
