Performance Test

This test is a speculative performance test about serving static assets from GCP.

Setup: web server serving a file of roughly 500KB gets deployed in a GCP VM. Load test: request the file using the external IP of the VM.

Prerequisites

1. Docker
2. Python 3
3. gcloud CLI

1. Create Web Server Image and Push to GCR

Create a docker image based on nginx in order to serve a static asset of 500KB+.

PROJECT_ID=kudos-spikes
# Generate a varies sizes of index.html 
for i in {1..7}; do python3 -c "for i in range(0,26000 * ${i}): print('test',end='')" > web-server/index-${i}00.html; done
docker build -t gcr.io/$PROJECT_ID/gcp-perf-test-nginx web-server/
docker push gcr.io/$PROJECT_ID/gcp-perf-test-nginx

2. Create Infrastructure and Deploy Web Server

Create a VM in Google Cloud Platform running a docker container based on the image previously built.

PROJECT_ID=kudos-spikes \
CONTAINER_IMAGE=gcr.io/$PROJECT_ID/gcp-perf-test-nginx \
bash infrastructure.sh

3. Run Test and Print Report

Run a load test using vegeta.

The load is configurable through the test/test.sh file.

docker build -t gcp-perf-test-nginx test/
URL="http://`gcloud compute instances describe gcp-perf-test-nginx --format='get(networkInterfaces[0].accessConfigs[0].natIP)'`"
docker run --env RESOURCE_BASE_URL="$URL" gcp-perf-test-nginx
