Go Rest API - CRUD Operations and stress test

This is a simple Rest API written in Go lang and stress tested using Vegeta

To start the web service

Run below command in your Go dev container:

go run main.go

Get Vegeta in Go Dev container

• Connect to your Go Dev container in VS Code Terminal
• Download the latest binary version to install Vegeta inside your container

wget https://github.com/tsenart/vegeta/releases/download/v12.8.4/vegeta_12.8.4_linux_amd64.tar.gz

• Unpack the binary file

tar xfz vegeta_12.8.4_linux_amd64.tar.gz

Move the binary file into /usr/bin to make it available system-wide. This step actually installs the Vegeta application in your Dev container:

sudo mv vegeta /usr/bin/vegeta

Running a load test with Vegeta

To run a load test during 60 seconds, run the following command.

echo "GET http://localhost:10000" | vegeta attack -duration=60s -rate=600 | tee results.bin | vegeta report

Stress test result in dev container

Caution: This stress test with rate 2000 requests per second for 60 seconds increased my CPU temperature from 44 degree celcius to 75+ degree celcius.
