Docker push commands requires two arguments to push the command into the registry.They are

1. Name of the Docker image.
2. Nmae of the registry to push the image.

Example:

If you want to push an image with the name as GFG-Image to the GFG-DockerImages repository which is located in the dockerhub registry then you will use the following command.

docker push GFG-Image GFG-DockerImages 

docker push <Name of the image> <Name of the repo>

In the place of <Name of the image> replace with your image name and in the place of <Name of the repo> replace with the your repository name.

By pushing an image to the DockerHub registry, we can create an instance of an image in which a particular type of software and applications are pre-installed and can be pulled again whenever you want to work on that particular type of image or application and run that kind of virtual machine. In the DockerHub there are millions of images you can also pull the default images which are created by particular organizations for example you can pull the Ubuntu image which is uploaded by Linux, and then install any software or application into that image like curl command, Jenkins, etc and then push that docker image to your docker hub registry. 

Docker Push

Docker push is a command which is used to push the docker images to the docker Private/Public registries. After building the customized docker image you need to push it to the remote registries from where other developers or DevOps engineers can access the image and work on it to push the image you can use the docker push command. It is an important step to perform because if you store it locally others can’t access the image but if it is available remotely others can access it.
