This is a full docker setup for nutshell by Calle
Cashu is an Ecash implementation based on David Wagner's variant of Chaumian blinding (protocol specs). Token logic based on minicash (description) which implements a Blind Diffie-Hellman Key Exchange scheme written down here. The database mechanics in Cashu Nutshell and the Lightning backend uses parts from LNbits.
The goal of this repo is to provide a full Dockerized cashu mint, with postreSQL easy to setup and run. This is based on a Lnbits funding source that must be specified inside the .env configuration file.
This will run a nutshell system with postgreSQL included.
First step is to get image from dockerhub
docker pull massmux/nutshell:0.15.0
- configure the .env file (use the .env.example provided)
- configure the docker-compose.yml file to define postgreSQL password
Minimal parameters to configure in .env
- mint private key
- funding Lnbits wallet details
- mint description
- cashu PostgreSQL database password to match with details in docker-compose.yml
Minimal parameters to configure in docker-compose.yml
- cashu PostgreSQL database password
If needed a different version, specify the image version in docker-compose.yml
Run
cd nutshell-docker
docker-compose up -d
