Kamil API Gateway

Kamil is a dynamic API gateway to be used with alongside micro service architecture. All you need to do is set the config.yaml file. The good thing about Kamil is that you don’t need to restart the gateway when you need to add another service.

Example

A simple config file looks like this;

routes:
 - route: /test1
   name: test1
   port: 8080
   request-types:
    - POST
   host: localhost
 - route: /test2/.*
   name: test2
   port: 8081
   host: localhost

• route is the regular expression that matches the request path. Being able to use regular expressions for route matching gives the user great flexibility.

• name field is mostly for the developer, it does not serve a goal for now.

• port is the port that the target server is listening

• request-types is an optional field for being able to control the requests more precisely.

• host is the IP of the target server.

A POST request sent to the ${KAMIL_IP}/test1 would be sent to the localhost:8080/test1. If request type is not POST, an error would be returned.

Program Arguments

• config-check-interval: Interval time in seconds that the config file would be checked for updates. Default is 2 seconds

• port: The port which the gateway will run. Default is 3000.

• config-file-name: Path of the config file. Default is ./config.yaml

TODO

• Add plugin support, and build some plugins for authantication.
• Enable adding new services from an endpoint.
• Create a User Interface
