Kong API Client

This repo has java code to auto configure apis on Kong Gateway based on provided list of apis in json file.

Jar File:

Prerequisites

kong gateway should be up and serving the api at localhost:8001

Note: Make sure you use 8001 port, it will fail otherwise since jar is hard coded with port 8001(May be you can update the code that take endpoint as argument)

kong-0.0.1-SNAPSHOT.jar

json file with api mapping listings, every api mapping configuration should have following objects as mandatory

methods: uris: upstream_url host

Sample Json file

{"data":[
{"methods":[
"GET",
"POST",
"OPTIONS"
],
"upstream_url":"http:/v1_0.captcha.service.alln-poc.coi:9000/tenants/ibm/",
"uris":["/tenants/ibm/v1/captcha"],
"name":"ibm"
}
}

or you can take dumb from kong server using following endpoint curl locolhost:8001/apis

save as json file and pass argument as shown below

java -cp kong-0.0.1-SNAPSHOT.jar com.kongapi.mapping.KongApi kong_apis.json

Jar will perform following tasks,

It compares the apis that are listed in the json file with existing api mappings in kong server,

• if new api are listed in the json file, it will add in the kong server,
• if api not listed in json and exist in kong server, it will be deleted from kong server
• if api is modified, it will update the existing api in the kong server.
