Build

run container locally:

docker-compose -f ./examples/docker/docker-compose_default.yaml up -d

then in tools:

change registry name in the build_docker.sh file

then run sh build_docker.sh to build & push & check on docker hub https://hub.docker.com/

Start Kubernetes & Docker on Personal Laptop & RAC

kubernetes setup:

  1. download minikube:

https://devopscube.com/minikube-mac/#:~:text=How%20to%20Setup%20Minikube%20on%20MAC%20M1%2FM2%201,get%20the%20following%20error.%20...%204%20Conclusion%20

  1. minikube start / minikube stop
kubectl config view
minikube: minikube kubectl config view

kubectl config current-context (either docker-desktop or minikube is fine here)
minikube: minikube kubectl config current-context

kubectl create namespace teastore (we use teastore here) / kubectl delete namespace teastore
minikube: minikube kubectl -- create namespace teastore / minikube kubectl -- delete namespace teastore
  1. for deployment & starting the pods:
kubectl apply -f teastore-new.yaml (I modified the file)
minikube: minikube kubectl -- apply -f teastore-new.yaml
  1. for verification:
kubectl get deployments -n teastore / kubectl delete deployment teastore-db -n teastore
minikube: minikube kubectl -- get deployments -n teastore

kubectl get services -n teastore / kubectl delete service teastore-db -n teastore
minikube: minikube kubectl -- get services -n teastore

kubectl get pods -n teastore / kubectl delete pods teastore-db -n teastore
minikube: minikube kubectl -- get pods -n teastore
  1. for scaling:
kubectl scale deployment teastore-db --replicas=1 -n teastore
minikube: minikube kubectl  -- scale deployment teastore-db --replicas=1 -n teastore

for checking ip address of pods:

kubectl get pods --all-namespaces
minikube: minikube kubectl  -- get pods --all-namespaces

kubectl get pod teastore-webui--${rest of id} -n teastore -o wide

get ip:
kubectl get svc -n teastore

URL of UI (TO BE TESTED):

personal laptop: http://localhost:30090/tools.descartes.teastore.webui/
test on RAC: curl http://10.1.11.211:8080/tools.descartes.teastore.webui/
(replace host url with your own...)

scale all to zero & delete resources:

kubectl get deployments --all-namespaces -o name | xargs -n 1 kubectl scale --replicas=0

kubectl delete deployments --all -n teastore

kubectl delete services --all -n teastore

kubectl delete pods --all -n teastore

Generate Load:

In one process: cd ./TeaStore/examples/httploadgenerator java -jar httploadgenerator.jar loadgenerator

In the other: cd ./TeaStore/examples/httploadgenerator java -jar httploadgenerator.jar director -s 127.0.0.1 -a ./increasingLowIntensity.csv -l ./teastore_browse.lua -o loadGeneratingResult.csv -t 8

or

java -jar httploadgenerator.jar director -s 10.1.11.211 -a ./increasingLowIntensity.csv -l ./teastore_browse.lua -o loadGeneratingResult.csv -t 8

After running the tests, shut down loadgenerator (the first process)

Locust Testing

- Short Duration Tests

  • Low Intensity (10 RPS)

    • Normal Spawn Rate:
    locust -f locustfile.py --headless --users 10 --spawn-rate 10 --run-time 1m  --csv=low-intensity-short
    • Low Spawn Rate:
    locust -f locustfile.py --headless --users 10 --spawn-rate 1 --run-time 1m  --csv=low-intensity-short-low-spawn-rate
    • High Spawn Rate:
    locust -f locustfile.py --headless --users 10 --spawn-rate 100 --run-time 1m  --csv=low-intensity-short-high-spawn-rate

  • Medium Intensity (50 RPS)

    • Normal Spawn Rate:
    locust -f locustfile.py --headless --users 50 --spawn-rate 50 --run-time 1m  --csv=medium-intensity-short
    • Low Spawn Rate:
    locust -f locustfile.py --headless --users 50 --spawn-rate 5 --run-time 1m  --csv=medium-intensity-short-low-spawn-rate
