Docker Compose

This guide assumes you are familiar with running a Union validator. If not, start with the validator guide.

docker-compose is a tool for running containers in a declarative manner. This allows for better automation, upgrades, and monitoring.

Configuration

Our base compose.yml is fairly simple:

services:
  node:
    image: "ghcr.io/unionlabs/uniond-release:$UNIOND_VERSION"
    volumes:
      - ~/.union:/.union
      - /tmp:/tmp
    network_mode: "host"
    restart: unless-stopped
    command: start --home /.union

Pay special attention to the volumes key. Here we map an already initialized ~/.uniond directory to the node service. The ~/.uniond directory should contain a config and data directory. To properly set these up, check out the validator guide.

Monitoring

We suggest adding additional monitoring services, such as datadog.
