Using Docker
============
It is assumed that you have already `setup docker <https://docs.docker.com/engine/installation/>`__.
Tendermint
----------
The application configuration and data will be stored at ``/tendermint`` in the
container. This directory will also be exposed as a volume. The ports 46656 and
46657 will be open for ABCI applications to connect.
Initialize tendermint:
::
mkdir /tmdata
docker run --rm -v /tmdata:/tendermint tendermint/tendermint init
Change ``/tmdata`` folder to any destination where you want to store Tendermint
configuration and data.
Tendermint docker image is stored on `docker hub <https://hub.docker.com/r/tendermint/tendermint/>`__.
Get the public key of tendermint:
::
docker run --rm -v /tmdata:/tendermint tendermint/tendermint show_validator
Run the docker tendermint application with:
::
docker run --rm -d -v /tmdata:/tendermint tendermint/tendermint node
Building images by yourself:
`This folder <https://github.com/tendermint/tendermint/tree/master/DOCKER>`__
contains Docker container descriptions. Using this folder you can build your
own Docker images with the tendermint application.
Ethermint
---------
The application configuration will be stored at ``/ethermint``.
Initialize ethermint:
::
mkdir /ethermintdata
wget -O /ethermintdata/genesis.json https://github.com/tendermint/ethermint/raw/master/setup/genesis.json
docker run --rm -v /ethermintdata:/ethermint tendermint/ethermint ethermint --datadir /ethermint init /ethermint/genesis.json
Start ethermint as a validator node: This is a two-step process: \* Run the
tendermint container and expose the ports that allow clients to connect. \* Run
the ethermint container. You will have to define where tendermint runs as the
ethermint binary connects to it explicitly. The --proxy\_app should contain the
ethermint application's IP address and port.
::
docker run --rm -d -v /tmdata:/tendermint tendermint/tendermint node --proxy_app=tcp://172.17.0.3:46658
docker run --rm -d -v /ethermintdata:/ethermint tendermint/ethermint ethermint --tendermint_addr tcp://172.17.0.2:46657
Building images by yourself:
`This folder <https://github.com/tendermint/ethermint/blob/master/scripts/docker>`__
contains Docker container descriptions. Using this folder you can build your
own Docker images with the ethermint application.
