Autoscan, A-Train and Bernard are no longer actively maintained. All projects are considered feature frozen and when compatibility with Google Drive, Plex, Emby, Jellyfin and the -arrs inevitably breaks, no fixes will be provided and such an event will officially mark these projects as end of life. As all three projects have permissible open source licenses, feel free to start a fork and continue development. Ownership of these repositories as well as the Docker images will not be transferred.

A-Train

A-Train is the official Autoscan trigger that listens for changes within Google Drive. It is the successor of Autoscan's Bernard trigger, which unfortunately contains enough logic errors to prompt a rewrite.

• Supports Shared Drives
• Service Account-based authentication
• Does not support My Drive
• Does not support encrypted files
• Does not support alternative authentication methods

Prerequisites

A-Train works exclusively through Shared Drives and Service Accounts. Shared Drives can only be created on GSuite / Google Workspace accounts.

First, you must create a Service Account and create a JSON key. Afterwards, if you do not have one already, create a Shared Drive within Google Drive and then add the email address of the Service Account to the Shared Drive (with Reader permission).

Finally, activate the Drive API in the Google Cloud Project where you created the Service Account.

Installation

A-Train has multiple installation options:

• Building A-Train from source (requires Rust to be installed)
• Downloading the pre-compiled binary for your platform
• Using the Docker image

Docker

The Docker image requires you to mount a volume with the A-Train configuration file (a-train.toml) and the Service Account key file (account.json) to /data.

docker run -d \
    --name a-train \
    --volume /path/to/data:/data \
    --restart unless-stopped \
    ghcr.io/m-rots/a-train

From Source

Requires the latest stable version of Rust to be installed.

cargo install --git https://github.com/m-rots/a-train --branch main

Configuration

The configuration file should be named a-train.toml.

• If you have installed A-Train from source or are using the binary, then A-Train will look for the a-train.toml and account.json files within the current working directory.
• If you're using A-Train within Docker, then a directory should be mounted to /data containing the a-train.toml and account.json files.

# a-train.toml
[autoscan]
# Replace the URL with your Autoscan URL.
url = "http://localhost:3030"
username = "hello there"
password = "general kenobi"

[drive]
# Path to the Service Account key file,
# relative to the configuration file.
account = "./account.json"
# One or more Shared Drive IDs
drives = ["0A1xxxxxxxxxUk9PVA", "0A2xxxxxxxxxUk9PVA"]

How to get the ID of a Shared Drive?

1. Open Google Drive in your preferred browser.
2. Click on Shared Drives on the left.
3. Double click on the Shared Drive you want to add.
4. You should now see all the files and folders at the root of this Shared Drive.
5. Now click on your browser's URL bar and copy the most-right value. It should have a structure similar to 0A1xxxxxxxxxUk9PVA.
