Create Pipeline build and push docker to Docker Registry with Github actions

GitHub Actions allows you to automate tasks in your development workflow, including building and pushing Docker images to Docker Hub. The workflow starts by checking out the code from your GitHub repository and setting up Docker Buildx. Next, it logs in to the GitHub Container Registry and sets a short version of the current commit hash as a variable. The workflow then builds and pushes the Docker image to the specified registry, using the cache-from and cache-to parameters to optimize build time. The cache-from parameter pulls the cache from a previous build, and the cache-to parameter saves the cache after the current build. This helps improve build performance and reduce the time it takes to create new Docker images. GitHub Actions simplifies the process of building and pushing Docker images by providing pre-built actions and features like Buildx, which automates cache management. By leveraging GitHub Actions and Docker, you can streamline your development workflow and increase productivity. The workflow file (workflow.yml) defines the steps involved in the automation process, including setting up the environment, building the Docker image, and pushing it to Docker Hub.
