Docker Instructions

Development/testing

For development or testing, or to spin up a btgd backend alongside lnd, check out the documentation at docker/README.md.

Production

To use Docker in a production environment, you can run lnd by first creating a Docker container, adding the appropriate command-line options as parameters.

$ docker create --name=lnd bitcoingold/lnd [command-line options]

Then, just start the container:

$ docker start lnd

Volumes

A Docker volume will be created with your .lnd directory automatically, and will persist through container restarts.

You can also optionally manually specify a local folder to be used as a volume:

$ docker create --name=lnd -v /media/lnd-docker/:/root/.lnd bitcoingold/lnd [command-line options]

Example

Here is an example testnet lnd that uses Neutrino:

$ docker create --name lnd-testnet bitcoingold/lnd --bitcoingold.active --bitcoingold.testnet --bitcoingold.node=neutrino --neutrino.connect=faucet.lightning.community

Start the container:

$ docker start lnd-testnet

Create a wallet (and write down the seed):

$ docker exec -it lnd-testnet lncli create

Confirm lnd has begun to synchronize:

$ docker logs lnd-testnet

This is a simple example, it is possible to use any command-line options necessary to expose RPC ports, use btgd or bgoldd, or add additional chains.
