microtest
Also available on Docker Hub: https://hub.docker.com/r/kellybrazil/microtest
This is a very simple web server that simulates a microservice running on port 8080. It replies with the server's hostname, server's IP address, the remote IP address, local server time, and the URI path from the client:
hostname: 04909ed3d467 ip: 172.17.0.3 remote: 172.17.0.1 time: Fri Aug 9 16:17:39 2019 path: /request_number_65
If the client request uses the POST method instead of GET, the output will be Content-Type: application/json and serialized in JSON:
{"hostname": "04909ed3d467", "ip": "172.17.0.3", "remote": "172.17.0.1", "time": "Fri Aug 9 16:19:13 2019", "path": "/request_number_100"}
This allows you to simply test load balancer and WAF configurations in microservices environments.
Client requests:
curl 1.2.3.4:8080/request_number_1
or
curl -X POST 1.2.3.4:8080/request_number_2
An example client shell script is included to show how you can increment the path to see which servers are getting which requests.
