Hello World

This pack is a simple Nomad job that runs as a service and can be accessed via HTTP.

Changing the Message

To change the message this server responds with, change the "message" variable when running the pack.

nomad-pack run hello_world --var message="Hola Mundo!"

This tells Nomad Pack to tweak the MESSAGE environment variable that the service reads from.

Consul Service and Load Balancer Integration

Optionally, it can configure a Consul service.

If the register_consul_service is unset or set to true, the Consul service will be registered.

Several load balancers in the The Nomad Pack Community Registry are configured to connect to this service by default.

The NginX and HAProxy packs are configured to balance the Consul service "hello-world-service", which is th default value for the "consul_service_name" variable.

The Fabio and Traefik packs are configured to search for Consul services with the tags found in the default value of the "consul_service_tags" variable.
