1. Look into sourcecode (main.go) to see that we read SERVICE_ID from env in deployment files And also look at how we connect each services together using HTTP, Consumer, AsyncTask, Scheduler, ParallelTask

2. Run command

curl -X POST "http://kubernetes.docker.internal/api/citizen"

{"ref":"atask-5577006791947779410"}

1. Run command

curl -X GET "http://kubernetes.docker.internal/api/citizen?ref=atask-5577006791947779410"

{"code":200,"data":{"citizen_id":"5577006791947779410","status":"success"},"status":"success"}

1. Run command to get pod name of [mail-consumer-xxxx] And use pod name to get logs

kubectl get po -n tcir-app | grep mail-consumer

kubectl logs [pod1] -n tcir-app
kubectl logs [pod2] -n tcir-app
kubectl logs [pod3] -n tcir-app

Consumer: main.go 112 Mail confirmation has sent to 5577006791947779410

1. Run command

kubectl exec -it client-util -n tcir-app -- bash
kafkacat -b "kfk1,kfk2,kfk3" -L | grep "confirm"

topic "when-citizen-has-confirmed" with 50 partitions:

1. Check message in partitions

kafkacat -b "kfk1,kfk2,kfk3" -C -e -t when-citizen-has-confirmed
Find {"citizen_id":"5577006791947779410"} in one of 50 partitions
exit

1. The scheduler will run at midnight and batch create & delivery id card to all of citizen in topic when-citizen-has-confirmed
