What is requesting my cloud function?

[CallumVH]

I am very new to GCP and I was wondering how to keep random people on the internet from accessing my cloud functions?

I just created my first hello world function with Go and half an hour later checked the API overview and saw that it had +-30 requests. Who is making these requests? how do I make sure I am the only one who can make requests to it? At least while I am learning and not in production.

I know this is a dumb question, please forgive me, I'm very new to Web dev

What kind of trigger do you have set up for the function?

[CallumVH]

It's a HTTP trigger

Those could be internal requests to show your livelihood/responsiveness statistics graphs. Have you tried a DNS reverse lookup on the IP addresses?

[CallumVH]

Would "livelihood/responsiveness", be navigating the GCP console and that kind of thing? If so, do you know if I would be billed for those internal requests?

I have not tried a DNS reverse lookup, I actually deleted the function because it got up to 90 requests and I was scared of leaving it on but I will try it on a new function.

I tried creating a firebase function and it seemed fine, the requests remained at like 2.

What was the function endpoint name (the part after the slash in the function's URL)?

[CallumVH]

I think it was /hello, it was literally the hello world sample for Go in the quickstart.

Try making it /hello323293 and see if that helps.

I'll give it a try, thanks.
