Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Summary

Running container-compose up -f deploy/docker-compose.yml from the project root resolves a bind mount source like ../data against the process CWD. That points outside project/, so the wrong, often empty directory is mounted. Relative bind-mount sources should resolve from the Compose file directory, as Docker Compose does.

Motivation and Context

build.context and service env_file already resolve relative to the Compose file directory. Bind-mount sources were the exception. Fixes #147.

What changed

Pass the selected Compose file directory to volume resolution so relative bind-mount sources resolve against it. Add static and container-backed regression coverage for ../data:/data with up launched from the project root.

Testing

• Added static coverage for parent-relative path resolution.
• Added a container-backed test that checks a healthcheck can read data/marker.txt from the mount.
• Could not run tests locally because Swift is unavailable in this environment. The Tests workflow is action_required pending maintainer approval; the container-backed regression also requires macOS with Apple Container support.

Code of Conduct

• I agree to follow this project Code of Conduct

Hi! Thanks for the PR. Can please explain what the actual issue you are trying to solve is?

I opened this PR to fix relative bind mounts such as ../data:/data. From the project root, container-compose up -f deploy/docker-compose.yml resolved ../data against the process CWD, pointing outside project/ and mounting the wrong, often empty directory. The expected path is project/deploy/../data → project/data, relative to the Compose file as Docker Compose does (#147).

The existing code already uses the Compose file directory for service env_file (ComposeUp.swift:935) and build.context (ComposeUp.swift:1350); bind mounts were the exception. This PR passes that directory to volume resolution and adds static and container-backed regression coverage.
