System Configuration

Run Iota Node using Docker Compose

Tested using:

  • ubuntu 20.04 (linux/amd64) on bare metal
  • ubuntu 22.04 (linux/amd64) on bare metal

Prerequisites and Setup​

  1. Confirm you have either Docker Engine or Docker Desktop installed, as well as Docker Compose.

  2. Update validator.yaml and place it in the same directory as docker-compose.yaml.

Add the paths to your private keys to validator.yaml. If you chose to put them in /opt/iota/key-pairs, you can use the following example:

authority-key-pair:
  path: /opt/iota/key-pairs/authority.key
protocol-key-pair: 
  path: /opt/iota/key-pairs/protocol.key
network-key-pair: 
  path: /opt/iota/key-pairs/network.key
  1. Place genesis.blob in the same directory as docker-compose.yaml. (available post genesis ceremony)

Connectivity​

You may need to explicitly open the ports outlined in Iota for Node Operators for the required Iota Node connectivity.

Start the node​

Start Iota Node in detached mode:

sudo docker compose up -d

Logs​

By default, logs are stored at /var/lib/docker/containers/[container-id]/[container-id]-json.log.

  • View and follow
sudo docker compose logs -f validator
  • By default all logs are output, limit this using --since
sudo docker logs --since 10m -f validator

Storage​

  • What is the size of the local Iota database?
# get the volume location on disk
sudo docker volume inspect docker_iotadb
# get the size of the volume on disk
sudo du -sh /var/lib/docker/volumes/docker_iotadb/_data
  • Delete the local Iota databases (volume)
sudo docker-compose down -v

Updates​

  • DO NOT delete the Iota databases
  1. Stop docker compose
sudo docker compose down
  1. Update docker-compose.yaml to reference the new image
-    image: iotaledger/iota-node:<OLD_IOTA_SHA>
+    image: iotaledger/iota-node:<NEW_IOTA_SHA>
  1. Start docker compose in detached mode:
sudo docker compose up -d
