coblox / bitcoin-core

An unopinionated docker image of bitcoin-core.

Bitcoin Core

An unopinionated docker image of bitcoin-core (bitcoind).

Usage

Simply use it the way you would use the bitcoind binary. All arguments are passed through to bitcoind.

For example:

docker run ghcr.io/coblox/bitcoin-core:latest -regtest

Bitcoin-CLI

The image also has bitcoin-cli installed. It is considered best practise to use the default ports of services inside docker containers. If you adhere to that, it is very easy to use bitcoin-cli with this image. Given a running container simple exec a shell into it:

docker exec -it CONTAINER_HASH /bin/sh

Depending on whether you started your container with -regtest, -testnet or -mainnet, simply pass this flag to bitcoin-cli as well and you are good to go. For example, given you started the container like this:

docker run -d ghcr.io/coblox/bitcoin-core:latest -regtest

Simply exec into the container:

docker exec -it CONTAINER_HASH /bin/sh

And use bitcoin-cli:

bitcoin-cli -regtest getblockchaininfo

bitcoin-core's Issues

Add native ZMQ support without depending on another docker image

#2 adds ZMQ support by depending on a different docker image that compiles bitcoind from scratch.

I think it would be good if we can depend on alpine linux only and install bitcoind from the repositories there. However, that one does currently not have ZMQ support.

ZMQ Support + minor improvements

Summary
create a new coblox/bitcoin-core docker images that:

• compiles with zmq
• makes bitcoin-cli ready to connect out of the box
  • copy the rpcport parameter in bitcoin.conf
  • copy the ~/.bitcoin/regtest/.cookie to ~/.bitcoin if regtest is activated
• Update to bitcoin 0.17.0
