Require fewer permissions

[C-Otto]

Currently the documentation states we need admin access. With lnd 0.9.0 it is possible to create macaroons with fewer permissions. See https://github.com/lightningnetwork/lnd/tree/master/macaroons#bakery

Looks like BTCpay doesn't even offer the (required) admin.macaroon :/

BTCPay's admin.macaroon is at the root folder of the container, not where the script is looking for it. You can do:

cd /var/lib/docker/volumes/generated_lnd_bitcoin_datadir/_data cp admin.macaroon data/chain/bitcoin/mainnet/

But then I've run into the issue with the docker script that LN is not running at the port where it should. Anyone used the script with BTCPayServer?

Is there some info on how to run it on the BTCPayServer? I would like to try the tool but couldn't figure how with explanation on the Readme. This is what I get when trying to run it.

docker run --rm --network=generated_default -it -v /var/lib/docker/volumes/generated_lnd_bitcoin_datadir/_data:/root/.lnd rebalancelnd/rebalance-lnd -l --grpc lnd_bitcoin:10009
