runner

This is a very basic service written in Go that generates GET HTTP requests to the test-service project and check the response for validity.

Usage

You need to compile the runner.go source file:

go build runner.go

Run the resulting binary file with one argument a URL to the service to test:

runner http://ipaddress

This binary is available in a docker file. If you have docker installed you can docker run this container:

docker run systemzoo/runner http://ipaddress

Development

To include the binary in the docker file the go code must be compiled with all the dynamically linked libraries included in the resulting binary. This is not default settings for the go build command. The build command looks like this:

GCO_ENABLED=0 go build -a -installsuffix runner.go

Use the included Makefile with the docker target to compile the go code, and build the docker container locally.

make docker

Summary

The runner loops forever generating GET requests to the url + randomInt.

It checks the response, logs the output code and looks for the random number in the response, logging an error if not found in the response.
