This is the easiest step once the Development Environment is already installed, the following are the options provided by DudaC:
|-w||PATH||Specify the web service sources path|
|-M||'k1=v1,kn=vn'||Override some web server config key/value|
|-u||Redirect server output to STDOUT|
In order to run a Web Service, the -w option allows to specify the path where the sources of the service are available. On each run DudaC will issue a make to re-compile the service in question.
As the service runs over a configurable HTTP server, it allows to modify specific configuration keys through the -M option, it support multiple key values in the format key1=value1,key2=value2. This is an example of running a service with custom configuration:
$ dudac -M 'Port=10000,Listen=18.104.22.168,Workers=5' -w /path/to/service
The configuration says it will use the TCP Port 10000, listening only on the interface owned by 22.214.171.124 IP address and the HTTP core will spawn five workers. For a complete list of the keys available please refer to the Monkey Server Core documentation section.
If for some reason you are printing information to the standard output, you can get those messages enabling the -u option.
This is an example running the 001_hello_world service:
dudac -w ../duda-examples/001_hello_world Duda Client Manager - v0.23 http://duda.io http://monkey-project.com [+] WebService : clean [OK] [+] WebService : build [OK] [+] Monkey : configure HTTP Server [OK] [+] Service Up : http://localhost:2001/hello/
The output says the service is reachable through the address http://localhost:2001/hello/ , doing a simple test with Curl we get:
$ curl -i http://localhost:2001/hello/ HTTP/1.1 200 OK Server: Monkey/1.4.0 Date: Mon, 11 Aug 2014 18:11:11 GMT Content-Length: 12 Hello World!
This is good enough, so next chapters will provide more information about available example services, internals and different aspects of this great technology.
