Docker Instructions
Development/testing
For development or testing, or to spin up a btcd
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 lightninglabs/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 lightninglabs/lnd [command-line options]
Example
Here is an example testnet lnd
that uses Neutrino:
$ docker create --name lnd-testnet lightninglabs/lnd --bitcoin.active --bitcoin.testnet --bitcoin.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 btcd
or bitcoind
, or add additional chains.
LND Development and Testing
To test the Docker production image locally, run the following from the project root:
$ docker build . -t lnd:master
To choose a specific branch or tag instead, use the "checkout" build-arg. For example, to build the latest commits in master:
$ docker build . --build-arg checkout=v0.8.0-beta -t lnd:v0.8.0-beta
To build the image using the most current tag:
$ docker build . --build-arg checkout=$(git describe --tags `git rev-list --tags --max-count=1`) -t lnd:latest-tag
Once the image has been built and tagged locally, start the container:
docker run --name=lnd-testnet -it lnd:1.0 --bitcoin.active --bitcoin.testnet --bitcoin.node=neutrino --neutrino.connect=faucet.lightning.community
