Globus setup documentation missing?

[craig-willis]

I'm trying to configure bdbag to fetch via Globus for Whole Tale bags that have been downloaded to a user's local system. Looking at https://github.com/fair-research/bdbag/blob/master/doc/config.md, I see that I need a keychain.json, but it's not clear how the average user would configure this on their local system.

Here's what I have working so far. It seems a bit complex, so I'm hoping there's a more straightforward way:

• Install GCP and configure access with "/" writeable (since the transfer uses full paths)
• pip install globus-cli and install sqlite3
• globus login (this creates the transfer token)
• sqlite3 ~/.globus/cli/storage.db "select * from token_storage where resource_server = 'transfer.api.globus.org'"
• Obtain the local endpoint ID from https://app.globus.org/endpoints
• Create ~/.bdbag/keychain.json:

[
    {
        "uri": "globus://",
        "auth_type": "globus_transfer",
        "auth_params": {
            "local_endpoint": "<local endpoint ID>",
            "transfer_token": "<access token from sqlite3 query>"
        }
    }
]

I'm happy to contribute a documentation PR. The basic requirements seem to be:

• Local endpoint and a way to obtain the endpoint ID
• A way to obtain a valid transfer token for the user
