Connect boltz to your LND install and run swaps using the cli. This tool makes possible to connect your existing LND node to boltz and use the cli to make atomic swaps and reverse swaps.
First of all clone the repository and build the image
cd boltzcli
docker build -t massmux/boltzcli .
or get the ready image
docker pull massmux/boltcli
now rename the file .boltz-lnd/boltz.toml.example in .boltz-lnd/boltz.toml and configure the part of LND section to point to your LND funds source.
now just run the daemon
docker-compose up -d
when the daemon is running, you can invoke the cli like this
docker exec -ti boltzd boltzcli getinfo
