Load test

To stress our restful server we will use wr, so please install it in your host. Since there are a lot of factors that interfere in a request (network delays, amount of available CPU/RAM in the hitter host, container, kernel configuration, etc) the result can variate according where and how the restful is deployed, but let's try to perform some basic configuration to run our stress test:

• Set unlimit values in your system (sometimes required root permission): ulimit -u unlimited
• Compile the source code and run it out of docker:

go build -o infura
RESTFUL_PORT=8080 ./infura run server --restful

• Run the load test: wrk -t12 -c400 -d30s http://localhost:8080/health
• In the meantime you can open this page to monitoring the resources: http://localhost:8080/dashboard

In my case the result was:

~ eavilesmejia$ wrk -t12 -c400 -d30s http://localhost:8080/health

TODOs

Here the pending stuff:

• Add swagger.json to restful api.
• Add structured logger to forward everything to stout.
• Deploy nginx as webserver with modsecurity and CRS (https://coreruleset.org/) to have a WAF in front of our service.
• More unit testing and better documentation.

NOTE: Github action is failing since we need to define the secret variable: INFURA_API_URL
