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.

Access http://dadjokes.online to see the service in action.

Docker image is Alpine 3.11 based running PHP 7.3 on Apache. The containter exposes both ports 8100 (HTTP) an 8143 (HTTPS) with a self signed certificated. If you wish to alter the container configuration, feel free to use the Dockerfile in this repo (https://github.com/yesinteractive/dad-jokes_microservice/blob/master/Dockerfile). Otherwise, you can pull the latest image from DockerHub with the following command:

docker pull yesinteractive/dadjokes

Typical basic usage (below example exposes dadjokes on host ports 8100 and 8143):

$ docker run -d \
  -p 8100:8100 \
  -p 8143:8143 \
  -e DADJOKES_NOECHO=FALSE \
  yesinteractive/dadjokes

Typical usage in Dockerfile:

FROM yesinteractive/dadjokes
RUN echo <your commands here>
