Cyphernode Proxy

Pull our Cyphernode image

docker pull cyphernode/proxy:latest

Build yourself the image

docker build -t cyphernode/proxy:latest .

Run image

If you want to run this container independently from Cyphernode:

docker run --rm -d -p 8888:8888 --network cyphernodenet --env-file env.properties cyphernode/proxy:latest `id -u cyphernode`:`id -g cyphernode` ./startproxy.sh

Configure your container by modifying env.properties file

Choose the right architecture

...by modifying the following line in Dockerfile:

COPY app/bin/lightning-cli_x86 ${HOME}/lightning-cli

...to lightning-cli_arm if running on a RPi.

Building docker image

docker build -t btcproxyimg .

Create sqlite3 database path and give rights

mkdir ~/proxydb ; sudo chown -R cyphernode:cyphernode ~/proxydb ; sudo chmod g+ws ~/proxydb
