This has been tested on Synology DSM 7.2.2 and running Synology Container Manager.

Steps to get this working:

1. Create a new Project in Container Manager. Name it actual-server or something identifiable.
2. Under the Yaml Configurations tab, paste this compose.yaml file as is.
3. Modify the yaml and insert your own Tailscale AuthKey.
4. Using the Synology File Station (or similar) make sure to create the correct folders so that the Docker files can save their data in the mounted volumes.
5. Copy up the serve-config.json into the /config folder volume mount as well.
6. If you haven't done so already, save and build the project. After a few minutes it should build and start the Actual Server container.
7. Open up your Actual Server client and add the https://<FQDN.TS.NET> of your container and it should see it and start syncing!

Go and budget away! Please file a bug issue if you run into any problems with this example!
