How to turn an IPFS node into a gateway node.

[TheDiscordian]

I was thinking it might be a good idea to clarify how a user might host their own gateway. It might be clear to some that they can use their go-ipfs node as a public gateway with some configuration, but the concepts/ipfs-gateway write-up doesn't make this explicitly clear. I think it'd be useful to at least make it explicitly clear what software might be used to setup a gateway (or maybe an example setup?).

I thought to ask this because a user asked about how to accomplish this here in #ipfs, and realised that I couldn't seem to locate a resource to point them to that'd offer them immediate clarity.

Good call. Having this doc would be very handy, especially for folks running local hackathons that want an in-house gateway to run things from! I've put the p2 tag on here for now, but can up the priority if more we find that more folks are requesting it.

Topics we should cover:

• path gateway vs subdomain gateway vs dnslink hosting
• in-depth explainers for common recipes (https://github.com/ipfs/go-ipfs/blob/master/docs/config.md#gateway-recipes)
• exposing data over HTTP vs running a gateway for hosting of web apps
  • explaining why origin isolation is important for web app hosting
  • why path gateways are not useful for websites (relative path issues, no origin isolation)
  • setting up wildcard subdomains TLS cert for subdomain gateway

I'm around for a review/call/chat if someone wants to pick this up.

Note to self: this should also include some protips / FAQ with things like using separate domain name to avoid issues described in https://www.notion.so/pl-strflt/Notes-on-Gateway-e811b958674a41bfb52fe46943123fd2
