Installing regtest

get the regtest enviroment ready

# Install docker https://docs.docker.com/engine/install/
# Make sure your user has permission to use docker 'sudo usermod -aG docker ${USER}' then reboot
# Stop/start docker 'sudo systemctl stop docker' 'sudo systemctl start docker'

sudo apt install jq
git clone https://github.com/lnbits/lnbits.git
cd lnbits
docker build -t lnbits/lnbits .
mkdir docker
git clone https://github.com/lnbits/legend-regtest-enviroment.git docker
cd docker
chmod +x ./tests
./tests # start the regtest and also run tests
sudo chown -R $USER ./data # Give the data file permissions for user

Running LNbits on regtest

add this ENV variables to your .env file

# Run LNbits
poetry run lnbits

# Run LNbits with hot reload
make dev

testing

chmod +x ./tests
./tests
# short answer :)
./tests && echo "PASSED" || echo "FAILED" > /dev/null

usage of the bitcoin-cli-sim, lightning-cli-sim and lncli-sim aliases

cd ~/lnbits/docker
source docker-scripts.sh
# use bitcoin core, mine a block
bitcoin-cli-sim -generate 1

# use c-lightning nodes
lightning-cli-sim 1 newaddr | jq -r '.bech32' # use node 1
lightning-cli-sim 2 getinfo # use node 2
lightning-cli-sim 3 getinfo # use node 3

# use lnd nodes
lncli-sim 1 newaddr p2wsh
lncli-sim 2 listpeers
