I have a containerized Dash app that I just simply run by using app.run(). The default port dash will listen on in this way is 8050; however, when I deploy this on railway (by creating a service out of my GitHub repo), the service starts up listening on 8080. How is this happening? I have a public hostname for the service, is that changing it somehow?
Related question, if I have a public hostname for my service, can I still connect to it on the internal private hostname from another service?

we inject a PORT=8080 variable and dash is probably listening on that if available.

yes
Is that injection part of the public hostname thing? Also, how do I turn off a public hostname?

its always injected regardless.
to turn it off would be the same as removing the domain.

gotcha, it wasn't showing up on mobile
i have more questions that are related but not about the title of this thread. should i open a new thread?

Also, if for some reason you need your app running on 8050 specifically, you can change the PORT variable in your service settings

if it doesn’t show there, add it and Railway will detect it
i'm trying to set up an nginx service (via a github hosted dockerfile and nginx config) that is supposed to proxy https://service-host.railway.app/some-other-app to the internal url of another service (my dash app). i'm having a hard time with the rewrites, i can get to the initial page but the returned links are not rewritten. trying to find a solution that is wholly in the nginx config. heres what i got:
server {
listen 80;
location /trump-polls/ {
proxy_pass http://some-other-app:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location / {
return 404;
}
}i did try rewrite /some-other-app(/.*)$ $1 break; but it didn't make a difference
sorry if this is too much about my own app and not railway, looking for any tips

tips? you need to use caddy
Well, i got it to work with caddy, but couldn't without making the dash app know about the path. Probably something to do with me not using a real wsgi. At least the caddy config is much simpler
