Funktion
open source event based lambda programming for kubernetes

Example


lets install the platform and a connector:

                    
$ funktion install platform
$ funktion install connector timer
                    
                

now lets create a function and bind it to a flow of events:

                    
$ funktion create fn -n myfunk -s 'module.exports = function(context, callback) { callback(200, "Hello, world!\n"); }'
$ funktion create flow timer://bar?period=5000 http://myfunk/
                    
                

if we have some javascript files in a folder called src called src we can apply them and watch the files via the -w flag. Then we can just edit the source files directly and the function runtime will update dyanmically:

                    
$ funktion apply -f src -w
                    
                

view the logs of the function:

                    
$ funktion logs hello
                    
                

debug the JavaScript using Chrome:

                    
$ funktion debug fn hello -c
