To start lnd, use command docker-compose up, and wait a minute.
To access your lnd container use docker exec -it lnd bash. Use lncli create to create a new wallet, and lncli unlock to unlock it. With an unlocked wallet, you can use the Thunderhub GUI to interact with your node. To access Thunderhub, visit localhost:3000 in your web browser (username: admin, password: password).
