Make someone or something awesome!
faas-cli deploy --image=diddledan/awesomify --name=awesomify
curl -o awesome.ogg http://example.com/function/awesomify?Testing+Functions
curl -X POST -d 'Testing Functions' -o awesome.ogg http://example.com/function/awesomify
Alternatively visit the URL http://example.com/function/awesomify?Testing+Functions in your browser (preferably Chrome or Firefox because they definitely support the audio codec, but Edge might work if you first install the Web Media Extensions pack from the store).
In all the above examples you need to replace
http://example.com/ with the URL to your functions server.
Open the file
awesome.ogg in a media player that supports Ogg+Opus codecs, of which there are many; I like VLC Media Player for it's cross-platform and supports every codec stance.
