Run A Node Using Docker

Overview

We provide a docker helper script called docker_ops.py to assist you in setting up a testnet or mainnet node. If you would like to view the complete help guide, refer to the Docker reference. Here you can see a simple script operating on the local test node and wallet programs.

Step 1: Pull Image

First you need to pull the necessary Docker image

docker pull everitoken/evt:latest

Step 2: Get the Script

Then get the helper script

wget https://raw.githubusercontent.com/everitoken/evt/master/scripts/docker_ops.py
chmod +x ./docker_ops.py

python3 is needed for this script, as well as these python packages: click and docker. If you are using Ubuntu, you can install required packages like this:

DEBIAN_FRONTEND=noninteractive apt-get install -y python3-pip && pip3 install click docker

If everything is right, you can get the help page

./docker_ops.py --help

Step 3: Setup the Local Node

In order to establish a connection between evtd and evtc, you need to set up a network in docker where the containers are kept in the same docker network. First, we need to create a network in Docker. You can simply call it:

./docker_ops.py network init

This will output:

Network: evt-net network is created

An default evt-net network will be created. If you'd like other name, you can add --name or -n option.

Use the following script to setup a local node.

./docker_ops.py evtd init
./docker_ops.py evtd create -t testnet --http-port=8888 --p2p-port=7888 --host=0.0.0.0 -- --http-validate-host=false --verbose-http-errors --plugin=evt::evt_link_plugin --producer-name=evt -e --delete-all-blocks
./docker_ops.py evtd start
./docker_ops.py evtd logs

If your logs now appear the same as below, then the local node has been set up:

Then the local node is setup.

Step 4: Setup Wallet Program

Use the scripts below to set up the wallet program.

./docker_ops.py evtwd init
./docker_ops.py evtwd create
./docker_ops.py evtwd start
./docker_ops.py evtwd logs

If your logs appear the same as below, then the wallet program is set up:

Then the wallet program is setup.

Step 5: Use the CLI Program

Now you can use our CLI program evtc, simply run as follows:

./docker_ops.py evtc --help
./docker_ops.py evtc wallet create

That's all! For a detailed look of this script, please refer to the Docker reference.
