Kong is an extensible open-source API layer (also known as API gateway or API middleware). Kong runs on top of any RESTful API and extends with plugins, they offer additional features and services beyond the core platform.
Kong was originally built at Mashape to provide over 15,000 APIs and microservices for its API Marketplace and generate billions of requests per month for more than 200,000 developers. Today, Kong is used in mission-critical deployments for both small and large organizations

Kong supports PostgreSQL 9.5+ and Cassandra 3.xx as its data store.
I have PostgreSQL installed, and the tutorial is as follows:
This article uses kong community edition as an example to install and deploy
Download Package:
Installation:
Check the version
or
Create a profile:
If your configuration is in All values are commented out, Kong will run with the default settings. At startup, Kong looks for several default locations that may contain the configuration file:
/etc/kong/kong.conf
/etc/kong.conf
kong_defaults.lua
nginx.lua
nginx_kong.lua
Initialize the database
initiate
When initializing the database and starting kong, you can specify the configuration file with the [-c /path/to/kong.conf] parameter.
After Kong starts, one is 8000, the other is 8001, and the 80000 port is the request entry port, and the user sends the request to the 8000 port of the Kong project first, and the kong forwards it to the real background service address according to the configured rules. The 8001 port is the management port, and a series of configurations such as plug-in settings, API additions, deletions, modifications, and load balancing are managed through the 8001 port.
Browser access IP: 8000, returns the following:
{"message":"no route and no API found with those values"}
kong admin management interface (If the external network is inaccessible, you can modify the binding configuration to allow public network access）
