Dadjokes.online: Microservice echo-service as an alternative to httpbin for testing k8s, docker, kong, istio, kuma, etc. Built on FSL php microframework. Who says testing and dev ops can't be fun?

Dad Jokes Microservice

Just a sample microservice or echo service used for testing API Gateways such as Kong, Kubernetes K8s, Openshift, Docker, Service meshes such as Kuma or Istio, etc. as an alternative to httpbin. Feel free to add your own jokes to this repo as well. In addition to a dad joke, the service will automatically echo back information about the incoming request. This is helpful for testing and troubleshooting. If you wish to not display echo back the request data, then just make the request against the /noecho endpoint or by configuring the dadjokes service with the noecho environment variable set to true.
