Docker Knots

Docker images of Bitcoin Knots for the linux/amd64, linux/arm64 and linux/arm/v7 architectures.

The images are based on Alpine Linux and run bitcoind without a configuration file.

The datadir is at the default /home/bitcoin/.bitcoin location. This directory is designated as a Docker volume.

This is the images' default ENTRYPOINT. Adjust the CMD if you want to run the bitcoind daemon with a different configuration.

ENTRYPOINT ["/usr/local/bin/bitcoind", "-nodebuglogfile", "-zmqpubrawblock=tcp://0.0.0.0:28332", "-zmqpubrawtx=tcp://0.0.0.0:28333"]

Customization example based on Docker Compose v2:

name: knots-signet

services:
  knots:
    image: 1maa/bitcoin:v26.1.knots20240325
    command: -signet -txindex=1

Available Versions

The binaries contained in these images are built from source automatically with GitHub actions, but they are not deterministic.
