Groestlcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of Groestlcoin is carried out collectively by the network. Groestlcoin is open-source; its design is public, nobody owns or controls Groestlcoin and everyone can take part. Through many of its unique properties, Groestlcoin allows exciting uses that could not be covered by any previous payment system.
This Docker image provides groestlcoin, groestlcoin-cli and groestlcoin-tx applications which can be used to run and interact with a groestlcoin server.
Images are provided for a range of current and historic Bitcoin forks. To see the available versions/tags, please visit the appropriate pages on Docker Hub:
To start a groestlcoind instance running the latest version:
$ docker run Groestlcoin/docker-groestlcoin
This docker image provides different tags so that you can specify the exact version of groestlcoin you wish to run. For example, to run the latest minor version in the 2.16.x series (currently 2.16.3):
$ docker run Groestlcoin/docker-groestlcoin:2.16
Or, to run the 2.16.0 release specifically:
$ docker run Groestlcoin/docker-groestlcoin:2.16.0
To run a Groestlcoin container in the background, pass the -d option to docker run, and give your container a name for easy reference later:
$ docker run -d --rm --name groestlcoind Groestlcoin/docker-groestlcoin
Once you have a Groestlcoin service running in the background, you can show running containers:
$ docker ps
Or view the logs of a service:
$ docker logs -f groestlcoind
To stop and restart a running container:
$ docker stop groestlcoind
$ docker start groestlcoind
Images are also provided for btc1, Bitcoin Unlimited, Bitcoin Classic, and Bitcoin XT, which are separately maintained forks of the original Bitcoin Core codebase.
To run the latest version of btc1 Core:
$ docker run NicolasDorier/btc1
To run the latest version of Bitcoin Classic:
$ docker run NicolasDorier/bitcoinclassic
To run the latest version of Bitcoin Unlimited:
$ docker run NicolasDorier/bitcoinunlimited
To run the latest version of Bitcoin XT:
$ docker run NicolasDorier/bitcoinxt
Specific versions of these alternate clients may be run using the command line options above.
The best method to configure the Groestlcoin server is to pass arguments to the groestlcoind command. For example, to run groestlcoin on the testnet:
$ docker run --name groestlcoind-testnet Groestlcoin/docker-groestlcoin groestlcoind -testnet
Alternatively, you can edit the groestlcoin.conf file which is generated in your data directory (see below).
By default, Docker will create ephemeral containers. That is, the blockchain data will not be persisted, and you will need to sync the blockchain from scratch each time you launch a container.
To keep your blockchain data between container restarts or upgrades, simply add the -v option to create a data volume:
$ docker run -d --rm --name groestlcoind -v groestlcoin-data:/data Groestlcoin/docker-groestlcoin
$ docker ps
$ docker inspect groestlcoin-data
Alternatively, you can map the data volume to a location on your host:
$ docker run -d --rm --name groestlcoind -v "$PWD/data:/data" Groestlcoin/docker-groestlcoin
$ ls -alh ./data
By default, Docker runs all containers on a private bridge network. This means that you are unable to access the RPC port (1441) necessary to run groestlcoin-cli commands.
There are several methods to run groestlcoin-cli against a running groestlcoind container. The easiest is to simply let your groestlcoin-cli container share networking with your groestlcoind container:
$ docker run -d --rm --name groestlcoind -v groestlcoin-data:/data Groestlcoin/docker-groestlcoin
$ docker run --rm --network container:groestlcoind Groestlcoin/docker-groestlcoin groestlcoin-cli getinfo
If you plan on exposing the RPC port to multiple containers (for example, if you are developing an application which communicates with the RPC port directly), you probably want to consider creating a user-defined network. You can then use this network for both your groestlcoind and groestlcoin-cli containers, passing -rpcconnect to specify the hostname of your groestlcoind container:
$ docker network create groestlcoin
$ docker run -d --rm --name groestlcoind -v groestlcoin-data:/data --network groestlcoin Groestlcoin/docker-groestlcoin
$ docker run --rm --network groestlcoin Groestlcoin/docker-groestlcoin groestlcoin-cli -rpcconnect=groestlcoind getinfo
For a complete example of running a Groestlcoin node using Docker Compose, see the Docker Compose example.

- To add a new Groestlcoin version, update versions.yml, then run
make update. - To make a change to the Dockerfile which affects all current and historical Groestlcoin versions, edit Dockerfile.erb then run
make update.
If you would like to build and test containers for all versions (similar to what happens in CI), run make. If you would like to build and test all containers for a specific Groestlcoin fork, run BRANCH=core make.
