jmb12686/loadtest-microservice repository overview

⁠Description

This application exposes a simple REST endpoint to execute a CPU intensive test. This docker image can be used for generating arbitrary CPU load. Load is generated by multiplying a BigInteger N iterations. The application load generator is a simple microservice, exposed via a RESTful API. The microservice utilizes Wildfly Swarm and the JEE Microprofile.

⁠Run Docker image:

By default, the Docker image will set the Wildfly Swarm port to 9999, and to run the image, execute the following command:

• docker run -p 8080:9999 loadtest-microservice

⁠Customizing server and docker port mappings

You can change the Wildfly Swarm (server) port at runtime with:

• docker run -p 8080:12345 -e SERVER_PORT=12345 loadtest-microservice

⁠Invoke the API:

• API URL -> http://localhost:PORT/loadtest-api/iterations/NUM_OF_ITERATIONS⁠
• Substitute PORT with mapped originating host port used in the docker run command. In the run command above, this would be 8080.
• Substitute NUM_OF_INTERATIONS with an numeric value
• Use cURL to issue GET requests to the endpoint, or simply use a browser to hit the URL.
