Hello there! Been trying out a few different services to see where I want to host my web app.
Frontend: React
Backend: Golang
I've got the backend up and running without any issues. I'm having some trouble getting my frond end up and running. I've tried with/without a docker file. Currently with the dockerfile the application is building fine, but crashes.
Error:
/docker-entrypoint.sh: /docker-entrypoint.d/ is not empty, will attempt to perform configuration
/docker-entrypoint.sh: Looking for shell scripts in /docker-entrypoint.d/
/docker-entrypoint.sh: Launching /docker-entrypoint.d/10-listen-on-ipv6-by-default.sh

nginx: [emerg] host not found in upstream "my_server.railway.internal" in /etc/nginx/nginx.conf:3
...
Dockerfile:
FROM node:14 as build
WORKDIR /client
COPY package.json .
RUN npm install
COPY . .
RUN npm run build
FROM nginx
COPY --from=build /client/build /usr/share/nginx/html
COPY nginx.conf /etc/nginx/nginx.conf
nginx.conf
http {
server {
server_name my_server.railway.internal;
location / {
root /usr/share/nginx/html;
}
location /api/ {
proxy_pass http://my_server.railway.internal;
}
}
}
events {}
From what I can tell from the docs and other support tickets something like this should be possible. Just not sure what I'm missing.
Thank you for any help!

create react app?
a year ago
Not sure I understand the question sorry. Yes, the front end is React
a year ago
was it made with create react app?
a year ago
or react scripts, however you wanna call it
a year ago
Ahhh, I beleve so. It's been a while since I initialized it.
Probably something like
npx create-react-app my-app --template typescript
a year ago
does the api endpoint have to live on the same domain as the frontend?
a year ago
No, but it's preferred.
I can do something like [api.my](api.my)_[domain.com](domain.com)
if I have to, but I'd prefer my_[domain.com](domain.com)/api
a year ago
okay fair enough
a year ago
okay so let's get started
a year ago
show me a screenshot of your railway project so I know what we are working with
a year ago
Just this?
a year ago
yep that's it
a year ago
can I see a screenshot of the frontend project in github?
a year ago
just the files and stuff
a year ago
a year ago
looking good
a year ago
I'm gathering information so I can work out the best course of action
a year ago
does the client have a public domain?
a year ago
You mean like here? Not yet, but I do have a domain I will use
a year ago
generate one, just for testing
a year ago
delete the Dockerfile and nginx.conf from your repo.
copy the nixpacks.toml and Caddyfile from this repo into yours.
if you have any custom build or start commands set in the clients service settings, please remove them.
a year ago
after that, let me know the outcome
a year ago
if that works the next step will be to join the frontend and backend under one domain, but one step at a time
a year ago
Build failed
ERROR: failed to solve: process "/bin/bash -ol pipefail -c npm run build" did not complete successfully: exit code: 1
Error: Docker build failed
I'm assuming it's because there's a few warnings that I have not cleaned up yet.
#19 77.49 Treating warnings as errors because [process.env.CI](process.env.CI) = true.
I'm new to Caddyfile, is there somewhere I can update this so it ignores warnings for now?
a year ago
Caddyfile has nothing to do with building your site.
set a service variable CI
to false
a year ago
Ahhh okay, will let that build.
a year ago
side note, please use this for sending me your build logs
the log snippet you sent didn't have any useful information.
a year ago
Okay, looks like the build worked and the app is live via the url I sent above.
a year ago
awesome, send another screenshot of the project please
a year ago
do you have a PORT
service variable set on the server service?
a year ago
do you have a PORT service variable set on the server service?
In railway? no
a year ago
can you show me the server code that starts listening?
a year ago
err = http.ListenAndServe(appConfig.Application.SERVER_DOMAIN, r)
if err != nil {
log.Fatal(err)
}
a year ago
what is the server domain set to
a year ago
Just the domain I want to use for the application
a year ago
please show me
a year ago
Show you how?
I have an env variable set up in railway that it picks up.
a year ago
screenshot please
a year ago
a year ago
show me the value
a year ago
on second thought, please use this code instead of what you currently have, that way we know it's correct
func main() {
// ...
// Use `PORT` provided in environment or default to 3001
var port = envPortOr("3001")
log.Fatal(http.ListenAndServe(port, handler))
// ...
}
// Returns PORT from environment if found, defaults to
// value in `port` parameter otherwise. The returned port
// is prefixed with a `:`, e.g. `":3001"`.
func envPortOr(port string) string {
// If `PORT` variable in environment exists, return it
if envPort := os.Getenv("PORT"); envPort != "" {
return ":" + envPort
}
// Otherwise, return the value of `port` variable from function argument
return ":" + port
}
a year ago
I'm not going to need a domain on that?
a year ago
nope
a year ago
a domain isn't applicable here, and if you say it worked on railway I will be shocked
a year ago
but then again, for some reason, you never did tell me what you had it set to
a year ago
I had it set to my domain (with no port).
a year ago
again, that's not telling me what it's set to
a year ago
I don't understand the secrecy, but either way, please use the code I provided instead
a year ago
Just not a domain I wanted to share. I'm not sure why knowing the exact domain matters. Could be my_[domain.com](domain.com)
and it wouldn't really make a difference.
a year ago
Updated the code. Waiting for it to build
a year ago
I understand that but details matter when dealing with these things, omitting details has dramatically increased the time it takes to resolve this and other help threads
a year ago
Okay, server built and is active.
a year ago
does it work?
a year ago
Do you mean does the client call it? No
a year ago
no, just the backend, does it work on its own?
a year ago
a year ago
on the client service, set a PORT
service variable to 3000
on the server service, set a PORT
service variable to 3001
a year ago
Okay that's done
a year ago
go ahead and deploy the reverse proxy
template into your project.
for the FRONTEND_HOST
variable, use [http://${{Client.RAILWAY_PRIVATE_DOMAIN}}:${{Client.PORT](http://${{Client.RAILWAY_PRIVATE_DOMAIN}}:${{Client.PORT)}}
for the BACKEND_HOST
variable, use [http://${{Server.RAILWAY_PRIVATE_DOMAIN}}:${{Server.PORT](http://${{Server.RAILWAY_PRIVATE_DOMAIN}}:${{Server.PORT)}}
a year ago
Deploying
What does the ENABLE_ALPINE_PRIVATE_NETWORKING
env variable do? I'm not seeing it referenced in the reverse proxy code
a year ago
there was a hyperlink under it that linked to docs explaining what it does
a year ago
but for the end user, you can ignore it
a year ago
so now you can remove the public domains from the server and client services because they will no longer be accessed publicly. you now use the domain on the proxy service
a year ago
So I would just add my custom domain to the proxy service then? Instead of the client?
a year ago
correct
a year ago
Is this generally the expected deploy time for the proxy?
a year ago
not at all
a year ago
did you missconfigure something?
a year ago
Let me double check
a year ago
I noticed I was missing the http://
on the env variables. I added that, but it seems the health check is still failing on the server
a year ago
full screenshot of your project please
a year ago
a year ago
why is the health check failing
a year ago
you might need to make changes to the Caddyfile, please have a read of the comments in the Caddyfile
a year ago
This is the correct health check plan? It was what it was set to when I created the template.
a year ago
your backend does have an /api/
path right?
a year ago
No, just figured this out. I updated it to /api/ping
. That fixed it.
a year ago
sorry but that's not the correct path you want to use
a year ago
okay now that's good
a year ago
so we in business?
a year ago
We are good!
Thank you so much for your help! Greatly appriciated!

happy to help!
