Bash Scripting for https://github.com/docker/getting-started/

build.sh Script:

The build.sh script is a core component of the Docker Getting Started project, responsible for orchestrating the Docker image building process. It leverages Bash scripting to automate the steps involved in creating a functional Docker image.

Script Breakdown:

  • Core Functionality: The script initializes Docker build, executes the Dockerfile, and interacts with Docker Hub to push the built image.

  • Options: The script offers a flexible command-line interface, allowing developers to tailor the build process:

    • -t or --tag: Specifies a tag for the Docker image. This tag is crucial for identifying and referencing the image during deployment.

    • -f or --file: Defines the Dockerfile used for the build. This enables the script to work with different Dockerfile configurations for diverse scenarios.

    • -p or --push: Activates pushing the built image to Docker Hub. This option streamlines deployment by uploading the image to a public repository.

    • -d or --debug: Enables debug mode, providing verbose output during the build process for troubleshooting purposes.

    • -h or --help: Displays available options and usage instructions.

Example Usage:

  • Building a Docker Image with a Specific Tag:

    ./build.sh -t my-app-image:latest
              
  • Building an Image Using a Custom Dockerfile:

    ./build.sh -f Dockerfile.dev
              
  • Pushing the Built Image to Docker Hub:

    ./build.sh -t my-app-image:latest -p
              
  • Building with Debug Output:

    ./build.sh -t my-app-image:latest -d
              

Script Source:

Note:

This script is a valuable tool for developers working with Docker, providing a streamlined approach to image building and deployment. By leveraging the script’s options, developers can customize the build process to meet their specific project requirements.
