DockerHub

After confirming that your application is functioning as anticipated, proceed to push the image to DockerHub.

If you already have an account, then you need to log in or create a new account.

Next, click Create Repository.

Please enter a repository name and description, and select the visibility option (Free/Private) based on your needs. I will opt for the free option.

Once done, click Create.

To upload the image to the registry, we must execute the following command.

Note: The username will be modified since you'll be deploying the image from your own account.

docker push mukulmantosh/django_docker:tagname
docker push <USER>/<REPO_NAME>:tagname

You need to build the image before pushing it to the registry.

Run the following command:

docker build -t <REPLACE_USER>/django_docker:1.0 .

The provided Docker command builds a Docker image with the tag "mukulmantosh/django_docker:1.0" using the current directory as the build context.

Breaking it down:

• docker build: This is the Docker command used to build Docker images.
• -t mukulmantosh/django_docker:1.0: This is the option to specify a tag for the image. In this case, the tag is "mukulmantosh/django_docker" with a version or label of "1.0". The format "repository_name/image_name:tag" is commonly used to identify Docker images.
• .: This period (dot) at the end of the command signifies the build context. It tells Docker to use the current directory (where the command is run) as the build context, which includes all the files and directories in that location for building the image.

So, when you run this command, Docker will build an image with the specified tag ("mukulmantosh/django_docker:1.0") using the files and configurations found in the current directory.

After successfully building the image, you can proceed with pushing it. However, before doing so, you must log in to Docker by executing the following command:

docker login

Once authenticated, you can push the image.

docker push <REPLACE_USER>/django_docker:1.0

After completing the process, you can view the outcome on DockerHub for the newly pushed image.
