Run A Node Using Docker

Overview

For the ease use of Docker and setup a local node or our Mainnet node, we provide a docker helper script called docker_ops.py. For the complete help, you can move forward to this page: Docker reference. Here we will only provide a simple script that will run both a local test node and wallet program.

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, and these python packages is also needed: click and docker. If you're 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

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 you can see the logs like:

Then the local node is setup.

Step 4: Setup Wallet Program

Then use the scripts below to setup wallet program

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

If you see the logs like

info  2018-11-28T09:50:57.252 thread-0  wallet_plugin.cpp:46          plugin_initialize    ] initializing wallet plugin
info  2018-11-28T09:50:57.252 thread-0  http_plugin.cpp:706           add_handler          ] add local only api url: /v1/evtwd/stop

info  2018-11-28T09:50:57.252 thread-0  http_plugin.cpp:706           add_handler          ] add local only api url: /v1/wallet/sign_transaction
info  2018-11-28T09:50:57.252 thread-0  http_plugin.cpp:706           add_handler          ] add local only api url: /v1/wallet/unlock

Then the wallet program is setup.

Step 5: Use the CLI Program

Now you can use out CLI program evtc, simply run like

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

That's all! For the detail usage of this script, please refer to Docker reference.
