parking-plus-service

Microservice to calculate distance and time.

Setup

See in docker-compose.yaml the needed environment variables
The CI/CD infrastructure will create and push the docker images to the Container Registry.
- How to load the image locally or in Kubernetes: https://gitlab.com/supercash/infra/k8s-cluster/-/wikis/Docker-Images

Continuous Integration (CI)

The service is built and integrated automatically using Gitlab CI/CD with the end result of a new Docker Image published to Gitlab's Docker Registry.

NOTE: All microservices at Supercash reuses the same Dockerized CI/CD pipeline as parameterized to avoid drift as part of the platform.

There are currently 7 microservices

Checks integrity of all service config
Runs all unit and integration tests
Publishes test results along with Code Coverage levels
Builds, tags, and pushes the Docker Image to the Docker Registry
Triggers a deploy to a GitOps environment based on the GitFlow.

Continuous Delivery (CD)

The service is deployed and reconciliated automatically using Gitlab CI/CD along with ArgoCD, which fetches the docker image from Gitlab's Docker Registry.

Checks integrity of deployment config
Requests ArgoCD reconciliation of deployed environment
Verifies public health check of the service of new environment

Building and Running

Gradle: use gradle bootRun
- It starts the service on port 8080
Just use docker-compose up, with optional --build to start a container.
- It starts the service on port 8082

ATTENTION: Make sure to adjust the port number that the host will listen to. Current is 8082 in docker-compose.yaml.

API

Go to the Swagger URL to discover the APIs available
- http://localhost:8082/swagger-ui/
- Keep the end / or else it fails to open
The OpenAPI endpoint for discovery is /swagger/docs/v2
- This is to support Gloo API Gateway (https://docs.solo.io/gloo/latest/installation/advanced_configuration/fds_mode/)
Stubs: located at https://gitlab.com/supercash/clients/distance-matrix-client-resttemplate
- Generated by https://github.com/marcellodesales/swagger-client-package-repo-gen

API Flows

The API Flow is as follows:

Clients must fetch the current Supercash sales: /v1/parking_lots/sales
- A sale has an ID and must be always submitted
Get the ticket status with the mapped sale ID: /v1/parking_lots/tickets/status
- Getting the status of the sale just in case
Authorize a payment based on the values: /v1/parking_lots/payments/authorize`
- Adjust the price value to 0 and the paid with the value
- Using the sale ID as well
Get the status of the payments: /v1/parking_lots/payments/status
- Verify if the payment went through

API `/v1/parking_lots/sales`

Just needs to have the tid and uid

curl http://localhost:8080/v1/parking_lots/sales
     -H "accept: application/json"
     -H "supercash_tid: 2323"
     -H "supercash_uid: 12123"

Tracing

SpringBoot implements Sleuth client to collect metrics.
Zipkin server is used to debug metrics of different services using traces, spans, etc.

How to Zipkin

Start the tools/zipkin docker-compose stack, open the URL http://localhost:9411/zipkin
Start the this service and make the requests to start using tracing

After making requests, go to Zipkin screen -> Find a Trace -> [+] -> serviceName=parking-plus-service -> [Run Query]

It will show the traces for the requests
Expand the traces, copy the value of X-B3-TraceId
- Paste at the field Search by trace ID and press ENTER.

Configuration

Sleuth Filter
logback-spring.yaml, property CONSOLE_LOG_PATTERN

Trace ID on the Client

The traces will show with the spans.

In the client-side, you can see the Trace ID through the HTTP Response Header X-Trace-ID. The example as shown above.

$ curl -i localhost:8080/v1/parkingplus \
    -H 'supercash_cid: marcello' \
    -H 'supercash_tid: 123' \
    -H 'content-type: application/json' \
    -d '{ "originAddress": "Maceio, Alagoas, Brazil", "destinationAddress": "Recife, Pernambuco, Brazil" }'
HTTP/1.1 200
X-B3-TraceId: 3e635cc4b8771243
api-version: v1
supercash_tid: 123
supercash_cid: marcello
Content-Type: application/json
Transfer-Encoding: chunked

{"distance":257055,"time":13519}%

Trace ID on the server

All the logs will display the traceID
- It is also included in the ACCESS logs
