This entry point will start 3 services: Datadog agent, CodeSee dd-bridge service and an example Node application.

#!/bin/bash

# start CodeSee Datadog Bridge
./codesee-dd-bridge &

# start Datadog agent
datadog-agent run &
/opt/datadog-agent/embedded/bin/trace-agent --config=/etc/datadog-agent/datadog.yaml &
/opt/datadog-agent/embedded/bin/process-agent --config=/etc/datadog-agent/datadog.yaml &

# start sample Node app to capture Traces
node index.js

heroku.yml

Add DD_API_KEY and CODESEE_BRIDGE_TOKEN key to Heroku Config Vars

Go to your Heroku App Setting page, add the 2 keys to your Config Vars section:

DD_API_KEY - you can get this key from here: https://app.datadoghq.com/organization-settings/api-keys
CODESEE_BRIDGE_TOKEN - we'll provide you this key during onboarding

Deploy and verify

Deploy your Heroku app and go to Datadog Traces and CodeSee Service Map to verify that your installation is working.
