DNS Documentation Clarity: specific instance

[coxley]

Pretty minor issue but figure I’d point it out.

Private networking says to use <alloc_id> in one of the DNS records. The runtime doc says that this is passed to the application via FLY_ALLOC_ID. The problem is that the env var is the full-length UUID whereas the DNS record is the first portion.

Maybe suggest using hostname instead?

Relevant docs:

• Private Networking · Fly Docs
• The Fly Runtime Environment · Fly Docs

Specifically…

<alloc_id>.vm.<appname>.internal: specific app instance

Oh yes, good catch. If you feel handy at docs PRs this is open source (but you definitely don’t have to tweak it): GitHub - superfly/docs
