Sleuth documentation apps

Apps used for the Sleuth documentation graphs . They're not using service discovery so don't treat them as reference production applications ;)

The apps are sending spans to Zipkin via RabbitMQ and spring-cloud-sleuth-stream.

Deploying to Cloud Foundry

1. Confirm the org and space you are logged into. The apps will be deployed here.

2. ./scripts/create_services.sh

3. ./scripts/build.sh && ./scripts/deploy_leaf_services.sh

4. Look up the route for each leaf service via cf apps and put them into acme-financial-back-office-microservice/manifest.yml

5. ./scripts/deploy_back_office_service.sh

6. Look up the route for the back office service via cf apps and put it into acme-financial-ui/manifest.yml

7. ./scripts/deploy_ui.sh

8. Confirm that everything is wired together properly with curl <uiUrlFromCfApps>/start. The output should be:

Hello from Acme Financial's Backend service. Calling Acme Financial's Account Service [Hello from Acme Financial's Account Microservice] and then Customer Service [Hello from Acme's Customer Microservice]

1. ./scripts/deploy_zipkin.sh

2. Confirm that the Zipkin UI is working via a browser using the URL from cf apps

Running the apps locally with RabbitMQ

You need to have Docker installed.

Provide the env variable DEFAULT_HEALTH_HOST pointing to your Docker Machine. By default it will be localhost. That way we'll start a RabbitMQ instance for you.

Run:

./scripts/start_with_zipkin_server.sh

Interactions

Run:

./scripts/curl_start.sh

You can then navigate to http://localhost:9411/ to see the Zipkin dashboard.

Troubleshooting

You can tail the .log files in build/ to see what it happening.
