Create a dockerignore template for Python projects

Creates a dockerignore template with patterns to ignore Python related files and directories.

Usage

dk_template_ignore_python(.dockerignore = NULL)

Arguments

.dockerignore

Optional existing dockerignore object to add patterns to

Value

A dockerignore object with Python-related ignore patterns

Details

This template adds patterns to ignore Python related files and directories, including:

• __pycache__/: Compiled Python files

• *.py[cod]: Python compiled files

• .pytest_cache/: PyTest cache

• .coverage, htmlcov/: Coverage reports

• .tox/, .nox/: Testing environments

• .venv/, venv/, ENV/: Virtual environments

• .Python, build/, dist/: Build artifacts

• .egg-info/, *.egg: Package metadata

• .ipynb_checkpoints/: Jupyter notebook checkpoints

These files are typically not needed in a Docker image or can be regenerated during the build process. Ignoring them can significantly reduce the build context size.
