README

tick ❤

Simple app that registers itself with an a8registry on a regular interval.

Prerequisites

The following instructions for this example assume the following:

  • This git repo cloned somewhere
  • jq
  • A Cloud Foundry deployed. Below we assume bosh-lite, but you can substitute your CF domain instead.

Example

Starting from this directory....

Push an instance of the service registry

cd ../registry
cf push registry
cd ../tick

Push 3 instances of tick app

cf push tick --no-start
cf set-env tick REGISTRY_BASE_URL "http://registry.bosh-lite.com"
cf start tick

Verify the # of app instances registered in service registry

$ curl -s registry.bosh-lite.com/api/v1/instances | jq '.instances | length'
  3

See details of app instances registered in service registry

$ curl -s registry.bosh-lite.com/api/v1/instances | jq .
