• Install NGINX with Lua

• Install Kubo 0.15

NGINX Config

• Use set_by_lua_block to extract host type from ngx.var.http_host

Kubo Config

DoH Resolvers:

"DNS": {
  "Resolvers": {
    "bit.": "https://dweb-dns.v2ex.pro/dns-query",
    "eth.": "https://dns.eth.limo/dns-query"
  }
}

Set a domain for public gateway so Kubo can recognize Host header.

"PublicGateways": {
  "gateway.example.com": {
    "UseSubdomains": true,
    "InlineDNSLink": true,
    "Paths": ["/ipfs", "/ipns"]
  }
}

You don't need a real certificate for this domain as it won't be exposed to Internet.
