Map multiple external ports to different internal ones

1

My app provides http/s on 80/443 and does SSL termination itself based on Letsencrypt. I further need another port (SSL-terminated with custom certificate) for GRPC, say 10000.

When I deploy my app I see

Services
TCP 80/443/10000 ⇢ 80

which is obviously wrong. So what I would like to do is set internal_port per service instead of globally.

Is there a way to do that? It’s the final missing piece to migrate my applications from appfleet.com…

Cheers,
Andi

Yes this will actually work just fine! You can have multiple services, each with an internal_port and one-or-more port entries. Your services config might look like this:

[[services]]
internal_port = 8080
protocol = "tcp"

    [[services.ports]]
    handlers = ["http"]
    port = "80"

    [[services.ports]]
    handlers = ["tls", "http"]
    port = "443"

[[services]]
internal_port = 10000
protocol = "tcp"

    [[services.ports]]
    handlers = ["tls"]
    port = "10000"

The indents aren’t necessary, but helpful to show what’s happening.

Oh yeah:

TCP 80 ⇢ 80
TCP 443 ⇢ 443
TCP 10000 ⇢ 10000

Great, much appreciated!
