Access to local file system inside Docker container?

[mikegehard]

I quickly looked through the docs but could find the answer so thought I'd ask here. If there is a better place, let me know.

I'm working to implement a human in the loop AI assisted TDD flow using Claude desktop and MCP servers: mikegehard/ai-assisted-agile-development#14

I'm at the point where I need to allow Claude to run commands locally and I wanted to use Docker containers for isolation from my local machine: mikegehard/ai-assisted-agile-development#13 (comment)

I was thinking about writing an MCP server but couldn't figure out how to attach the local file system into the container: mikegehard/ai-assisted-agile-development#14 (comment)

Do y'all have any docs that would show how that works? I'm guessing I could just include a Dockerfile in my project to build the container with a volume mount but thought I'd ask.

Thanks!

Hi @mikegehard ! Not sure if I understand your question completely, but it sounds like you're trying to mount local folders into the docker container? (like with bind mounts)?

With swe-rex Docker deployment (see the config docs), you should be able to just pass your arguments.

So I think something like this:

docker_config = DockerDeploymentConfig(
	image="...",
	docker_args=["--mount type=bind,src=<host-path>,dst=<container-path>"]
)

or similarly with volume and then

deployment = DockerDeployment.from_config(docker_config)

Does that answer your question?

Yes I want to mount a local directory into the Docker container so that I can run commands against my project source code.

I'll give this a try and update the docs to include instructions if it work out.
