Configure Automatic Push to Docker Registry using GitHub Actions

[koladev32]

Objective

Implement automatic pushing of Docker images to a Docker registry using GitHub Actions. This will streamline our CI/CD pipeline, ensuring that the latest builds are always available for deployment and testing.

Requirements

• Trigger: The workflow should be triggered on push events to the main branch and on tag creation for release versions.
• Docker Image Build: Compile the application and build the Docker image using the latest code from the main branch.
• Docker Registry Login: Authenticate with the Docker registry using credentials stored as GitHub secrets.
• Docker Image Push: Push the built image to the Docker registry when a new release is made.
• GitHub Actions Workflow: Create a workflow file (e.g., .github/workflows/docker-push.yml).
• GitHub Secrets: Store Docker registry credentials securely as GitHub secrets.
• Documentation: Document the workflow briefly in the repository's README or relevant documentation.
• Testing: Optionally, include a step to run tests before building and pushing the Docker image.
• Security: Ensure the secure storage and access of Docker registry credentials.

Acceptance Criteria

• The Docker image is automatically pushed to the registry upon each commit to the main branch and upon tag creation.
• The image is tagged appropriately.
• The workflow and its configuration are documented.
• Docker registry credentials are handled securely.
