rbillon59/wiremock-loadtest Docker 镜像 - 轩辕镜像

Wiremock dockerized for performance testing

Wiremock standalone HTTP server Docker image

Why for performance testing ?

By default, Wiremock is not configured to handle an heavy load. Here is what is changed in the configuration :

• --no-request-journal --> By default, Wiremock keep all requests logs in the Java heap, so a memory exhaust happen, fast. We disabled it
• --async-response-enabled=true --> By default, request responses are synchronous, here async

How to use this image

Getting started

Pull latest image

sh
docker pull rbillon59/wiremock-loadtest

Start a Wiremock container

sh
docker run --rm -p 8080:8080 -v "${PWD}/samples/stubs":/home/wiremock rbillon59/wiremock-loadtest

Running multiple instances of Wiremock behind a reverse proxy

sh
docker-compose up --scale wiremock=5 -d

Doing this you will spawn 5 instances of the mock behind a nginx reverse proxy which will load balance across the instances. It's useful to quickly launch multiple instance across a single host.

Running inside a kubernetes cluster

Update the Kubernetes configmap to add your stubs then :

sh
kubectl apply -f kubernetes.yaml

The kubernetes.yaml file contains a definition of the wiremock deployment and a load *** service to expose wiremock (no need for a specifif nginx). You can deploy this inside your kubernetes cluster to mock direcly beside your application.

The horizontal auto scaler will scale up the replicas if the CPU threshold is reached

Samples

Two examples mappings are available in the samples/stubs/mappings folder. /static is a pre-defined json body while /dynamic take the path to create the json response.

Access http://localhost:8080/static to show static json message
Access http://localhost:8080/dynamic/whatever to show dynamic json message
