anax32/bitcoind repository overview

⁠Bitcoin Fullnode from source

Builds a docker image of the bitcoin core daemon from the github mirror: https://github.com/bitcoin/bitcoin⁠

Build contains:

• wallet
• zmq
• transaction db

⁠Usage

Build docker image as a multi-stage build. The first stage sets up the environment, clones the repo and does the build, the second stage creates a containe with the binaries and minium dependencies to run.

Use this build script to cache the build environment:

# build env first and cache
# ~2Gb/~30 mins
docker build \
  --target build-stage \
  --cache-from anax32/bitcoind:build-latest \
  --cache-from anax32/bitcoind:build-v0.20.1 \
  -t anax32/bitcoind:build-latest \
  -t anax32/bitcoind:build-v0.20.1 \
  --build-arg BITCOIN_VERSION_TAG=v0.20.1 \
  .

# fullnode compile using cache
# ~120Mb/~1 min
docker build \
  --target fullnode \
  --cache-from anax32/bitcoind:build-latest \
  --cache-from anax32/bitcoind:build-v0.20.1 \
  --cache-from anax32/bitcoind:latest \
  --cache-from anax32/bitcoind:v0.20.1 \
  -t anax32/bitcoind:latest \
  -t anax32/bitcoind:v0.20.1 \
  .

Run docker image:

docker run \
  -u $(id -u):$(id -g) \
  -v $(pwd)/data:/block-data \
  anax32/bitcoind

block chain data is stored in the container /block-data dir (in the above, this is the $(pwd)/data host mount).

bitcoin.conf configuration script is loaded from the /config/bitcoin.conf container directory. Create a local bitcoin.conf and mount over this directory to provide your own config. Default config is pulled from the bitcoin github repo⁠ at line 108 of the Dockerfile.
