avcfg

HTTP simple configuration server that exposes properties from a json file

Start the http server: server -type http -http.port 8080

Start the tcp server: server -type tcp -tcp.port 8087

Considering we have this sample json configuration file called aws-integration-feature.json:

{
	"enable": "true",
	"credentials":{
		"key":"ABffds7yggf",
		"secret":"hb65555"		
	},
	"location":{
		"region":"eu-west-1",
		"bucket":"my-log-bucket"
	},
	"caching":{
		"key.ttl.ms":"120000",
		"key.idle.ms":"60000"
	}
}

We can fetch the properties in the following way with HTTP:

1. enable: http://localhost:8080/json/aws-integration-feature/enable
2. key in credentials: http://localhost:8080/json/aws-integration-feature/credentials/key
3. key.ttl.ms in caching: http://localhost:8080/json/aws-integration-feature/caching/key.ttl.ms

The properties are cached for 5 minutes. If any json files are added or updated, there's no need to restart the server.

General HTTP request pattern:

GET http://<IP address>:<PORT>/json/<JSON filename without extension>/<property path in the json file>

For tcp, there are two sample clients just to show the protocol:

1. A golang-based client
2. A java8 client

Docker images:

1. http server: docker.io/alinvasile/avcfg-http-server (docker file in docker/avcfg-http-server/Dockerfile)
2. tcp server: docker.io/alinvasile/avcfg-tcp-server (docker file in docker/avcfg-tcp-server/Dockerfile)
