git-filter-repo

A Docker Image with git-filter-repo integrated

Usage

Build the image or pull the latest image from Docker Hub

# Build
docker build -t roemer/git-filter-repo .
# Pull
docker pull roemer/git-filter-repo

Create a mirror clone

git clone --mirror <your repo> repo_bare

Run the image and mount the cloned repo into it

# Windows
docker run --rm -it -v C:\temp\repo_bare:/tmp2 roemer/git-filter-repo /bin/bash
# Linux
docker run --rm -it -v /tmp/repo_bare:/tmp2 roemer/git-filter-repo /bin/bash

Switch to the directory inside the container

cd tmp2

Note: Depending on your setup, you might need to add the tmp2 folder to the trusted paths:

git config --global --add safe.directory /tmp2

Run the desired commands

# Example which removes two paths
git filter-repo -invert-paths -path unneded_path1 -path unneded_path2

# Example which extracts a subfolder with history and uses this as new root
git filter-repo --subdirectory-filter subfolder/

Run the garbage collection on the git

git reflog expire --expire=now --all && git gc --prune=now --aggressive

Replace the original with the cleaned repo or change the remote and push the cleaned repo there

# Untested
git push --mirror
