Refactor the API to use go-kit

[krasi-georgiev]

Started looking at the api code and I think it can be improved by using the go-kit package.

@tomwilkie what do you have against go-kit?
I haven't used it, but it looks like a good fit.

@krasi-georgiev Can I take the initiative to help out .
This is the code right ?

[krasi-georgiev]

that would be great!
I started a topic in the def list, but hasn't been discusses yet so need a bit more input from the other maintainers.

I am leaning towards gokit + swagger spec generation via annotations.

@krasi-georgiev I'll go through the api code and check out go-kit + swagger and follow the thread.

Thanks.
post your findings or questions in the Google groups thread.

Hi I’m Katsuya,
I’m thinking to participate GSoC’18, and I’d like to work on Prometheus.
I found this issue Prometheus’s ideas page,
It’s sounds very interesting.
Could you tell me more detail of this issue?
If there is anything I can do, I want to help.

[krasi-georgiev]

I did a quick research and started a dicsussion in the Prometheus mailing list.
https://groups.google.com/forum/#!topic/prometheus-developers/IebVSsE2_Gk

also started a doc to take some notes

overall I am leaning towards go-kit with some code annotations to auto generate the code based on the code annotations/comments next to each endpoint.

if you have an opinion can post it in the mailing list to get some more comment and can also ping me on irc #prometheus-dev if you have any questions.

@Bo0km4n should hang around a bit longer in the IRC. Saw your question, but you were not in the irc anymore. if you put krasi in front of the question I will get a notification and better chance to get a quick reply.

[Bo0km4n]

Oh, I’m sorry,,, I’m the first time to use IRC. Even if you skipped a private chat with the “/privmsg command”, I got an error. If you do not bother you, I’d like to contact you by email or github issue.

it might be a bit difficult of you have more than one question , but lets try , fire away.

[Bo0km4n]

Fmm... Ok, I think I will try a conversation on irc. Could you tell me about private chat command? I tried command “/privmsg krasi hello, nice to meet you” But actually, I couldn’t send message to you. What command when you send private message to other user? Sorry to hear persistently.

[krasi-georgiev]

send me a message in the main room
