reddcoincore/reddcoind

This repo builds reddcoind in an auditable way, and packages it into a minimal Docker containers provided for various CPU architectures.

The work here was initially based on lncm/docker-bitcoind and ruimarinho/docker-bitcoin-core, but has significantly diverged since.

Details

• All git-tags (and most commits) are signed by ABEDC4489B9188E45C2342A82E91240B293BA5D3
• All git-tags (and most commits) are opentimestamps-ed
• All builds aim to be maximally auditable. After git tag push, the entire process is automated, with each step printed, and the code aiming to be easy to follow
• All builds are based on Alpine
• Cross-compiled builds are done using our (also auditable) qemu
• To fit build and complete make check test suite, BerkeleyDB is build separately here
• Each build produces binaries for: amd64, arm64v8, and arm32v7
• All architectures are aggregated under an easy-to-use Docker Manifest
• All git-tags are build automatically, and with an auditable trace
• Each successful build of a git tag pushes result Docker image to Docker Hub
• Images pushed to Docker Hub are never deleted (even if lnd version gets overridden, previous one is preserved)
• All final images are based on Alpine for minimum base size
• All binaries are stripped
• Each git-tag build is tagged with a unique tag number
• Each minor version is stored in a separate directory (for the ease of backporting patches)

NOTE: ZMQ block and tx ports are set to 28332 and 28333 respectively.

Tags

NOTE: For an always up-to-date list see: https://hub.docker.com/repository/docker/reddcoincore/reddcoind/tags

• v4.22.8
• v4.22.7

Usage

Pull

First pull the image from Docker Hub:

docker pull reddcoincore/reddcoind:v4.22.7

NOTE: Running above will automatically choose native architecture of your CPU.

Or, to pull a specific CPU architecture:

docker pull reddcoincore/reddcoind:v4.22.7-arm64v8

Start

First of all, create a directory in your home directory called .reddcoin

Next, create a config file. You can take a look at the following sample: thebox-compose-system (1).

Some guides on how to configure reddcoin can be found here (reddcoin git repo)

Then to start reddcoind, run:

docker run  -it  --rm  --detach \
    -v ~/.reddcoin:/data/.reddcoin \
    -p 45444:45444 \
    -p 45443:45443 \
    -p 18444:18444 \
    -p 28333:28333 \
    --name reddcoind \
    reddcoincore/reddcoind:v4.22.7

That will run reddcoind such that:

• all data generated by the container is stored in ~/.reddcoin on your host machine,
• port 45443 will be reachable for the RPC communication,
• port 45444 will be reachable for the peer-to-peer communication,
• port 28332 will be reachable for ZMQ block notifications,
• port 28333 will be reachable for ZMQ transaction notifications,
• created container will get named reddcoind,
• within the container, reddcoind binary is run as unprivileged user reddcoind (UID=1000),
• that command will run the container in the background and print the ID of the container being run.

Interact

To issue any commands to a running container, do:

docker exec -it reddcoind BINARY COMMAND

Where:

• BINARY is either reddcoind, reddcoin-cli, reddcoin-tx, (or reddcoin-wallet on v0.18+) and
• COMMAND is something you'd normally pass to the binary

Examples:

docker exec -it reddcoind reddcoind --help
docker exec -it reddcoind reddcoind --version
docker exec -it reddcoind reddcoin-cli --help
docker exec -it reddcoind reddcoin-cli -getinfo
docker exec -it reddcoind reddcoin-cli getblockcount

Docker Compose

Here is a docker-compose.yml for mainnet

version: '3'
services:
  reddcoin:
    container_name: reddcoind
    user: 1000:1000
    image: reddcoincore/reddcoind:v4.22.8
    volumes:
      - ./reddcoin:/data/.reddcoin
    restart: on-failure
    environment:
    - RPC_SERVER=1
    - RPC_USERNAME=[create a user name]
    - RPC_PASSWORD=[UseALongAndHardToGuessPassWord]
    - RPC_PORT=45443
    - RPC_ALLOW_IP=127.0.0.1/0
    stop_grace_period: 15m30s
    ports:
      - "45443:45443"
      - "45444:45444"
      - "28332:28332"
      - "28333:28333"

First, ensure that the reddcoin/ folder is in the directory containing docker-compose.yml. Then, Docker Compose will mount the reddcoin/ folder to /data/.reddcoin.

Troubleshooting

Reddcoind isn't starting

Here are some possible reasons why.

Permissions for the reddcoin data directory is not correct

The permissions for the reddcoin data direct is assumed to be UID 1000 (first user).

If you have a different setup, please do the following

# where ".reddcoin" is the data directory
sudo chown -R 1000.1000 $HOME/.reddcoin
