build-docker-auto.yml

# This GitHub Actions workflow is designed to trigger a manual Docker build for each modified Dockerfile.
#
# Workflow Name: build-docker-auto
# Short Description: Trigger Build Docker Manual for Each modified Dockerfile
#
# Triggers:
# - On push events to any branch except 'main' and 'dev', if any Dockerfile.* is modified.
# - On pull request events to 'main' and 'dev' branches, if any Dockerfile.* is modified.
#
# Jobs:
#   - Runs on the latest Ubuntu environment.
#   - Steps:
#     1. Check out the repository using actions/checkout@v4.
#     2. Identify modified Dockerfiles using git diff and store them in the environment variable 'dockerfiles'.
#     3. For each modified Dockerfile, trigger the 'build-docker-manual' workflow with the Dockerfile path and additional parameters.
#
# Environment Variables:
# - GITHUB_TOKEN: Used for authentication to trigger the 'build-docker-manual' workflow.
