## What is bitcoind?
_from [bitcoinwiki](https://en.bitcoin.it/wiki/Bitcoind)_

bitcoind is a program that implements the Bitcoin protocol for remote procedure call (RPC) use. It is also the second Bitcoin client in the network's history.

## Usage
### How to use this image
This image contains the main binaries from the Bitcoin Core project - `bitcoind`, `bitcoin-cli` and `bitcoin-tx`. It behaves like a binary, so you can pass any arguments to the image and they will be forwarded to the `bitcoind` binary:

```sh
$ docker run --rm -it seegno/bitcoind \
  -printtoconsole \
  -regtest=1 \
  -rpcallowip=172.17.0.0/16 \
  -rpcpassword=bar \
  -rpcuser=foo
```

By default, `bitcoind` will run as as user `bitcoin` for security reasons and with its default data dir (`~/.bitcoin`). If you'd like to customize where `bitcoind` stores its data, you must use the `BITCOIN_DATA` environment variable. The directory will be automatically created with the correct permissions for the `bitcoin` user and `bitcoind` automatically configured to use it.

```sh
$ docker run --env BITCOIN_DATA=/var/lib/bitcoind --rm -it seegno/bitcoind \
  -printtoconsole \
  -regtest=1
```

You can also mount a directory it in a volume under `/home/bitcoin/.bitcoin` in case you want to access it on the host:

```sh
$ docker run -v ${PWD}/data:/home/bitcoin/.bitcoin -it --rm seegno/bitcoind \
  -printtoconsole \
  -regtest=1
```

You can optionally create a `Dockerfile` in the root of your application directory:

```Dockerfile
FROM seegno/bitcoind
```

Then simply run:

```sh
$ docker build -t my/bitcoind
$ docker run --rm -it my/bitcoind
```

Or with `docker-compose`:

```yml
bitcoind:
  image: seegno/bitcoind
  command:
    -printtoconsole
    -regtest=1
```

## Image variants
The `seegno/bitcoind` image comes in multiple flavors:

### `seegno/bitcoind:latest`

### `seegno/bitcoind:<version>`
Based on a slim Debian image, targets a specific version branch or release of Bitcoin Core (e.g. `0.12.0rc5`, `0.12`).

### `seegno/bitcoind:<version>-alpine`
