Docker Time Machine Server

This repository can be used to build a docker container that is a minimal configuration Time machine server for MacOS. The container creates a network resource that MacOS can back itself up to with Time Machine.

Environment Variables

Various possible environment variables are listed in the docker-compse sample below. All of these variables are optional, but it is highly recommended to at least set the SMB_PASSWORD variable to something other than the default value.

Sample Docker Compose File

To build the container, create a file named docker-compose.yaml containing something like contents below in a folder of your choosing, and from the same folder, run docker-compose build. This may take some time the first time it is run. To run the container in the foreground, use docker-compose run, or docker-compose run -d to run in the background.
