README

tick ❤

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

Prerequisites

The following instructions for this example assume the following:

• Go 1.6+
• cf-networking-release
  • cloned under ~/workspace/cf-networking-release
• Ensure GOPATH is set to cf-networking-release:
  • export GOPATH=~/workspace/cf-networking-release
• jq
• Deploying to bosh-lite
  • Cloud Foundry org and space created and targetted

Setup

• Build and Deploy the service registry

cd ~/workspace/cf-networking-release/src/github.com/amalgam8/amalgam8
GOOS=linux GOARCH=amd64 go build -o a8registry cmd/registry/main.go
cf push registry -c './a8registry' -b binary_buildpack -d bosh-lite.com

Example

Push 3 instances of tick app

cd ~/workspace/cf-networking-release/src/example-apps/tick
cf push tick -i 3 -m 32M --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
