I’m unable to get running an app which attaches multiple services on internal ports to different external subdomains. I’m using nginx to reverse proxy. Everything is working as expected when run locally.
e.g. myapp.com should map to internal port 8000, api.myapp.com should map to internal port 8001.
What I see instead is that only one of the 2 web services is receiving requests, whichever comes first in my fly.toml (i.e. both api.myapp.com and myapp.com resolve to the same service), when deployed to fly. Otherwise the services are running as expected.
I have a fly.toml like (shortened):
# this doesn't work
app = "myapp"
kill_signal = "SIGINT"
kill_timeout = 5
processes = []
[[services]]
http_checks = []
internal_port = 8000
protocol = "tcp"
[[services.ports]]
force_https = true
handlers = ["http"]
port = 80
[[services.ports]]
handlers = ["tls", "http"]
port = 443
[[services]]
http_checks = []
internal_port = 8001
protocol = "tcp"
[[services.ports]]
force_https = true
handlers = ["http"]
port = 80
[[services.ports]]
handlers = ["tls", "http"]
port = 443
An nginx configuration:
server {
server_name myapp.com;
listen 80;
listen [::]:80;
location / {
proxy_pass http://localhost:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
server {
server_name api.myapp.com;
listen 80;
listen [::]:80;
location / {
proxy_pass http://localhost:8001;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
Alongside a Dockerfile which runs the processes and nginx.
I suspect something with fly internal routing configuration might be causing some unspoken behavior here. I’ve tried many things – going through fly docs, configuring DNS, nginx, and debugging my local web services, which all seems to be configured and running OK.
EDIT: Here is the fixed fly.toml for future viewers
# this works
app = "myapp"
kill_signal = "SIGINT"
kill_timeout = 5
processes = []
[[services]]
http_checks = []
internal_port = 80
protocol = "tcp"
[[services.ports]]
force_https = true
handlers = ["http"]
port = 80
[[services.ports]]
handlers = ["tls", "http"]
port = 443
