dockerfile-git-hash 0.1.0

A tool to update commit hashes in Dockerfiles

dockerfile-git-hash

dockerfile-git-hash is a command-line tool to update the commit hashes in a Dockerfile. It parses the Dockerfile for git checkouts, fetches the latest commit hashes for the repositories, and updates the Dockerfile accordingly.

Installation

You can install dockerfile-git-hash using pip:

pip install dockerfile-git-hash

Usage

dockerfile-git-hash <dockerfile_path> <destination_path>

• <dockerfile_path>: Path to the Dockerfile or directory containing the Dockerfile
• <destination_path>: Destination path for the updated Dockerfile

If a directory is provided instead of a Dockerfile, dockerfile-git-hash will look for a file named "Dockerfile" in that directory.

Features

1. Parses Dockerfiles for git checkouts
2. Fetches the latest commit hash for each repository
3. Updates the Dockerfile with the new commit hashes
4. Writes the updated Dockerfile to the specified destination
5. Copies additional files (run.sh, run.bat, build.sh, build.bat, docker-compose.yaml) if present

Example

dockerfile-git-hash ./my_project/Dockerfile ./updated_dockerfile/Dockerfile

This command will update the Dockerfile in the my_project directory and save the updated version in the updated_dockerfile directory.
