Yes, you can run `git filter-repo` from a Docker container. Here are the steps to do so:

### Step 1: Pull a Docker Image with Git and Python

First, pull a Docker image that has both Git and Python installed. The official Python image should work well.

```sh
docker pull python:3.9-slim
```

### Step 2: Create and Run a Docker Container

Run a Docker container from the pulled image and mount your local repository into the container.

```sh
docker run -it -v /path/to/your/repo:/repo python:3.9-slim /bin/bash
```

Replace `/path/to/your/repo` with the actual path to your local repository. This command mounts your local repository to `/repo` inside the container and opens a bash shell.

### Step 3: Install `git` and `git-filter-repo` in the Container

Inside the Docker container, install `git` and `git-filter-repo`.

```sh
apt-get update
apt-get install -y git
pip install git-filter-repo
```

### Step 4: Navigate to Your Repository and Filter the Module

Navigate to your repository directory and use `git filter-repo` to filter out the module’s history.

```sh
cd /repo
git filter-repo --subdirectory-filter module-directory
```

### Step 5: Push the Filtered History to the New Repository

Add the new subproject repository as a remote and push the filtered history.

```sh
git remote add subproject https://gitlab.com/your-username/your-subproject-repo.git
git push subproject main
```

### Step 6: Clean Up and Exit

After pushing the changes, you can clean up and exit the Docker container.

```sh
exit
```

### Full Example

Here's the full sequence of commands, assuming `/path/to/your/repo` is the path to your local repository and `module-directory` is the directory you want to filter:

```sh
docker pull python:3.9-slim
docker run -it -v /path/to/your/repo:/repo python:3.9-slim /bin/bash

# Inside the Docker container
apt-get update
apt-get install -y git
pip install git-filter-repo
cd /repo
git filter-repo --subdirectory-filter module-directory
git remote add subproject https://gitlab.com/your-username/your-subproject-repo.git
git push subproject main
exit
```

This process will allow you to filter the Git history of a module and push it to a new GitLab subproject using a Docker container.
