# 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](../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 [snipped] 2018-05-01 02:28:01.201 [INF] RPCS: RPC server listening on 127.0.0.1:10009 2018-05-01 02:28:01.201 [INF] LTND: Waiting for chain backend to finish sync, start_height=2546 2018-05-01 02:28:01.201 [INF] RPCS: gRPC proxy started at 127.0.0.1:8080 2018-05-01 02:28:08.999 [INF] LNWL: Caught up to height 10000 2018-05-01 02:28:09.872 [INF] BTCN: Processed 10547 blocks in the last 10.23s (height 10547, 2012-05-28 05:02:32 +0000 UTC) ``` 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.
