Can I install Homarr on a Raspberry Pi?

@Vishal let's continue here ECONNREFUSED means that it's not reachable, because it says middleware that's not that great. How do you host it?

Vishal•4d ago

railway.app

MeierschlumpfOP•4d ago

Okay makes sense that it does not work then probably. It expects a "HOSTNAME" env variable from docker, but not sure how this works in railway

export const serverFetchApi = createTRPCClient<AppRouter>({
  links: [
    httpLink({
      url: `http://${process.env.HOSTNAME ?? "localhost"}:3000/api/trpc`,
      transformer: SuperJSON,
      headers: createHeadersCallbackForSource("server-fetch"),
    }),
  ],
});

export const serverFetchApi = createTRPCClient<AppRouter>({
  links: [
    httpLink({
      url: `http://${process.env.HOSTNAME ?? "localhost"}:3000/api/trpc`,
      transformer: SuperJSON,
      headers: createHeadersCallbackForSource("server-fetch"),
    }),
  ],
});

Vishal•4d ago

what should be the value i'll try if that works

MeierschlumpfOP•4d ago

In theory it would be the hostname that it has within docker. Because that does not work it might not be possible at all as it only allows an http endpoint with port 3000

Vishal•4d ago

hmm I didn't get you

MeierschlumpfOP•4d ago

HOSTNAME is an environment variable that is set by docker and would need to be defined, because we can not just access the trpc endpoint from outside the container

Vishal•4d ago

if i define "HOSTNAME" env variable will that work HOSTNAME=3000

MeierschlumpfOP•4d ago

Not sure, I don't quite know how it works on railway Maybe it makes more sense to ask them why they dont' have a HOSTNAME env variable set (if this is the case)

Vishal•4d ago

ok let me try asking them done fixed

MeierschlumpfOP•4d ago

Okay and how? Maybe we could add a installation guide to the docs

Vishal•4d ago

here's the template I have updated https://railway.com/template/_c4Kr9 can add this Markdown to the docs

Vishal•4d ago

i had to add PORT=3000 and HOSTNAME=0.0.0.0

MeierschlumpfOP•4d ago

But thats not correct, right?

Vishal•4d ago

aah somehow it takes time to update

MeierschlumpfOP•4d ago

Okay I see Is this template also available as code or only as template

Vishal•4d ago

only the template no code i guess

MeierschlumpfOP•4d ago

Okay so the template is like a form where you fill out custom env variables, docker image and tag and so on?

Vishal•4d ago

it shows updated yes

MeierschlumpfOP•4d ago

Great okay But that also means you have to manually update it (nvm you have latest)

Vishal•4d ago

yes but if i add versions i have update manually but the tag i have put as latest so i don't need to update or maybe i misunderstood your question

MeierschlumpfOP•4d ago

It was not a question and rather me thinking loud, sorry I noticed while writing the sentence, that you have latest and so don't need to update it in that regard

Vishal•4d ago

here's the one with my referral its upto you both are same https://railway.com/template/_c4Kr9?referralCode=vishify Markdown

[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/template/_c4Kr9?referralCode=vishify)

[![Deploy on Railway](https://railway.com/button.svg)](https://railway.com/template/_c4Kr9?referralCode=vishify)

MeierschlumpfOP•4d ago

Vishal•4d ago

MeierschlumpfOP•4d ago

Yeah it's still the old one, I'll have to find out how to change it xD

Vishal•4d ago
