Overview

As a proof of concept, I put together a Dockerfile that uses noVNC to make the GUI available, so one can start the wallet container, browse to localhost:8080, and interact with the wallet as if it were installed locally.

TODO: Add dependencies for using a ledger; volumes so a wallet can be backed up externally, and stop being lazy by using the root user.

The pertinent issue for this repo is seed generation - when I reach the verification step, the application segfaults after entering the final word. No logs appear to be generated. Running the wallet in a container (or at least, in this particular configuration) might just be a bad idea, but it was concerning to see seed generation causing a segfault.

Usage

docker-compose up -d then browse to localhost:8080, then click Connect.

The container that results from the code below is running a minimally configured openbox - right click the desktop and use the Electrum - Ravencoin link, or use the Terminal link and execute ./run_electrum from /opt/rvn.

docker-compose.yml

version: '3.7'

services:
  wallet:
    build:
      context: ./docker
      dockerfile: Dockerfile
    restart: always
    ports:
      - 8080:8080
