Run it

You just need to run:

./scripts/deploy.sh

This script will:

• Create a traefik_default docker network if it doesn't exist yet
• Run docker-compose build to build docker images
• Run docker-compose up -d to start services

Services are listed below:

• 5 instances of the Effective Barnacle server on random unused ports (localhost:XXXX)
• Effective Barnacle client (localhost:3000)
• Effective Barnacle orchestrator (localhost:9000)
• Traefik reverse proxy (localhost:80)
• MongoDB (localhost:27017)

You can also customize ports and other variables with the following environment variables:

• EB_TRAEFIK_PORT (80)
• EB_DOMAIN_NAME (localhost)
• EB_ORCHESTRATOR_PORT (9000)
• EB_ORCHESTRATOR_SECRET (supersecret)
• EB_SERVER_DOCKER_IMAGE (effective-barnacle_backend)
• EB_MAX_CLIENTS_PER_SERVER (5)
• EB_DEFAULT_SERVERS_NB (5)
• EB_MONGO_HOST (mongodb)

Shut it down

Just run:

./scripts/stop.sh

To make sure that Effective Barnacle is shutting down with this command, your server Docker image should be named effective-barnacle_backend.
