Docker on Mac runs mainly inside a virtual machine and offers poor performance for volume mounts.

Some projects like Dinghy improves this performance by using NFS but it's still slow compared with files hosted directly in the container.

docker-osx-dev was built to provide better performance but has some important drawbacks, mainly files created in the container in a shared mounted are not synced back and worse are deleted when the next sync runs.

This project attempts to provide a bi-directionnal syncing between files on the Mac host and a not mounted folder directly in the container, by using:

• a derived version of docker-osx-dev to provide syncing from the mac to the container,
• a container based on mickaelperrin/lsyncd to provide syncing from the container to the mac.

Configuration is not transparent like with dinghy or docker-osx-dev. It uses mainly :

• a spectific comment in the docker-compose.yml file to configure syncing from the host to the mac,
• an additional container.

An example of configured docker-compose.yml is provided in this project.

Dinghy must be configured on the host and used to run Docker.

1/ Be sure that dinghy is running

2/ Launch the containers and the sync daemon by running the start-container-and-sync.sh

3/ Launch the test script test.sh which perform some basic operation on the host and in a contaier to show how sync works.
