Sample Example to Push an image to Docker Hub
The following steps guides in pushing an image to the Dockerhub:
Step 1: Create an account on Docker Hub or use an existing one if you already have one.
Step 2: Click on the “Create Repository” button, put the name of the file, and click on “Create”.
Step 3: Now will “tag our image” and “push it to the Docker Hub repository” which we just created.
- Now, run the below command to list docker images:
$ docker images
- The above will give us this result
REPOSITORY TAG IMAGE_ID CREATED SIZE afrozchakure/python-test latest c7857f97ebbd 2 hours ago 933MB
- Image ID is used to tag the image. The syntax to tag the image is:
docker tag <image-id> <your dockerhub username>/python-test:latest
$ docker tag c7857f97ebbd afrozchakure/python-test:latest
Step 4: Push image to Docker Hub repository
$ docker push afrozchakure/python-test

What is Docker?
Docker is a set of Platforms as a service (PaaS) products that use Operating system-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels. All containers are run by a single operating system kernel and therefore use fewer resources than a virtual machine.
