Notice

The master branch by default on this repository is for Antelope/Leap@3.1. If you are looking for a version that works with EOSIO/EOS@2.x, please check out the v2.x branch of this repository.

Requirements

The usage of this repository makes use of docker and docker-compose. This root docker container can be orcehstrated into other platforms (Swarm, K8s, etc) as well so long as you understand how to deploy to them.

A quick guide on setting up docker and docker-compose can be found here.

Get the code

Pull down this repository.

git clone https://github.com/greymass/docker-nodeos.git
cd docker-nodeos

Configuration

To configure these containers, you'll first need to copy the example .env file into the root of the project. You can then change the variables in this file to impact both the building of the container as well as its startup.

cp configs/docker/default.env .env

This file contains the following parameters:

# The git repository of the nodeos (EOSIO) repository to use
NODEOS_REPOSITORY=https://github.com/AntelopeIO/leap.git

# The branch/tag of nodeos to checkout during the build process
NODEOS_VERSION=v3.1.2

# A snapshot (compressed as tar.gz) to use during the startup of this node
NODEOS_SNAPSHOT=https://snapshots.greymass.network/jungle/latest.tar.gz

# Peers to inject into the nodeos configuration
NODEOS_PEERS=peer.jungle3.alohaeos.com:9876 jungle.eosn.io:9876 jungle3.eosrio.io:58012

The second thing you'll need to configure is the nodeos configuration file itself. Create a copy of this configuration file as outlined below, and it'll be passed to the container for use.

cp configs/nodeos/example-minimal-api.config.ini configs/config.ini

This file is your standard nodeos configuration. More information is available on the official documentation.

Build the container

During your first run and any time afterwards which you make changes to the configuration files, you'll need to rebuild the containers. Run the following command to kick off the build process.

docker-compose build

Run the container

With the containers build, now you just need to run them.

docker-compose up -d

The nodeos instance within the container will bind to the ports on the host as defined in the docker-compose.yaml file.

Stop the container

If you need to stop the container:

docker-compose down

Additional Predefined Configurations

A number of configurations have been setup for different methods of operation. Listed below are list of these configurations as well as the commands to quickly spin up that instance type.

API (Minimal)

This is the default configuration shown in the documentation above. This type of configuration launches one or more nodeos processes from a snapshot and load balances API requests between them. They also are configured to only keep 1 days worth of recent blocks and have the account query API enabled.

This API configuration is meant to serve out most requests, with the exception being they won't be able to serve out older blocks (v1/chain/get_block).

cp configs/docker/default.env .env
cp configs/nodeos/example-minimal-api.config.ini configs/config.ini

Once copied, edit these configuration files (if needed).

If you had previously used the docker-compose.override.yaml file for another configuration, clear that out.

git reset --hard docker-compose.override.yaml

Then build, and start it up:

docker-compose build
docker-compose up

API (Minimal) + nginx

The above configuration can also be used to scale up multiple API instances, which can be load balanced behind nginx. To use this configuration you'll need to copy the example nginx.conf into place and make any modifications you may need.

cp configs/nginx/nginx.conf configs/nginx.conf

When starting, you'll just need to pass an extra parameter into the docker-compose up command outlined in the previous example.

docker-compose build
docker-compose --profile nginx up

If you'd like to scale up to multiple instances, you'll use the --scale option in the docker-compose up command.

docker-compose build
docker-compose --profile nginx up --scale nodeos=2

P2P Relay (Minimal)

This configuration launches a single nodeos instance from a snapshot with only the p2p network enabled. This can be used as a p2p relay for multiple API node instances to prevent excess network chatter. Since it is launched from a snapshot it won't be useful in resyncing blocks to other nodes in the p2p network.

To use this repository to setup one of these instances, copy and modify the configuration for nodeos. Perform these commands from the root directly of the repository:

cp configs/docker/default.env .env
cp configs/nodeos/example-minimal-p2p.config.ini configs/config.ini

Once copied, edit these configuration files (if needed).

Then modify the docker-compose.override.yaml file to contain the following information:

version: '3.6'
services:
    nodeos:
        extends:
            file: ./configs/docker/nodeos-minimal-p2p.yaml
            service: nodeos

Then build, and start it up:

docker-compose build
docker-compose up

Reload nginx upstreams

docker-compose exec nginx nginx -s reload

Logging

A logging.json file can now be added to the ./configs folder of the project to create a custom nodeos logging configuration.

The file placed in this location will be included during the build process and used as nodeos starts up.

Remote endpoint for logging.json

With this docker configuration designed to be scalable to multiple instances, a simple logging.json copy into the configs folder won't be able to identify individual containers.

For this reason, you can now input those values into the .env file:

# Remote Logging - Endpoint
NODEOS_LOGGING_ENDPOINT=www.your.server.com:12201

# Remote Logging - Operator Name
NODEOS_LOGGING_OPERATOR=operator_name

# Remote Logging - Network Name
NODEOS_LOGGING_NETWORK=jungle4

When these values are found in the .env file, the initialization process of each container will modify the logging.json file to inject values relevant to each container. The resulting output will be similar to:

{
    "name": "net",
    "type": "gelf",
    "args": {
        "endpoint": "NODEOS_LOGGING_ENDPOINT",
        "host": "${NETWORK}${HOSTNAME}",
        "_operator": "NODEOS_LOGGING_OPERATOR",
        "_network": "NODEOS_LOGGING_NETWORK"
    },
    "enabled": false
}
