Pushing Docker images to Docker Hub involves a few steps, including creating a Docker Hub account, logging in to Docker Hub from the command line interface (CLI), and using the docker push command to upload images. Below are the detailed steps:
Create a Docker Hub Account: If you haven't already done so, go to the Docker Hub website (https://hub.docker.com/) and sign up for a new account. Follow the prompts to create your account.
Install Docker: Make sure you have Docker installed on your local machine. You can download and install Docker Desktop from the official Docker website (https://www.docker.com/products/docker-desktop).
Log in to Docker Hub from CLI: Open a terminal or command prompt on your local machine and log in to Docker Hub using the
docker logindocker login
Tag your Docker image:
Before pushing your Docker image to Docker Hub, you need to tag it with your Docker Hub username and the repository name. This is necessary so Docker knows where to push the image. Use the docker tag command to tag your image.
docker tag image_name username/image_name:latest
Replace <image_name> with the name of your local Docker image, <username> with your Docker Hub username
Push your Docker image:
Once your image is tagged correctly, you can push it to Docker Hub using the docker push command
docker push yourhubusername/image_name
Verify the upload: After the upload is complete, you can verify that your image is now available on Docker Hub by visiting your Docker Hub profile page or searching for the repository on the Docker Hub website.
That's it! You have successfully pushed your Docker image to Docker Hub.
