Java is not found

It seems Java is not available out of the box. How do I configure Railway service to have Java so I can run a Java process?

what provider is currently being detected?

Kurdiez•13mo ago

I don't need to build. I just need to run already built Java server How do I check this?

Brody•13mo ago

build logs please https://bookmarklets.up.railway.app/log-downloader/

Kurdiez•13mo ago

I don't know how to use that bookmarklets It's confusing

Brody•13mo ago

please follow the instructions

Kurdiez•13mo ago

I did, but when I click on bookmarklet from the bookmarks bar, it just goes to the page you sent me And that makes sense because it's in the bookmarks bar...

Brody•13mo ago

you did not follow the instructions

Kurdiez•13mo ago

I did. I opened the desired service and then clicked on the bookmarklet in the bookmarks bar It looks like your instructions are not detailed enough... What is it that you would like to see? The build log?

Brody•13mo ago

the build logs produced from that bookmarklet

Kurdiez•13mo ago

This is from Railway Build logs

Brody•13mo ago

please use the bookmarklet

Kurdiez•13mo ago

Is there a YouTube video or something that explains how to use bookmarklet?

Brody•13mo ago

there is an arrow and 3 steps on that page please follow the instructions

Kurdiez•13mo ago

Yes... I followed those 3 steps.

Brody•13mo ago

okay send the build logs please

Kurdiez•13mo ago

Kurdiez•13mo ago

I got the log from bookmarklet.. that was confusing to me sorry

Brody•13mo ago

Brody•13mo ago

do you have a nixpacks.toml file?

Kurdiez•13mo ago

Brody•13mo ago

any kind of config file relating to railway?

Kurdiez•13mo ago

no nothing. First time using Railway

Brody•13mo ago

do you have any service variables set?

Kurdiez•13mo ago

Brody•13mo ago

do you have a start command set in the service settings?

Kurdiez•13mo ago

yes bin/run.sh root/config.yaml the run.sh calls java to run the server

Brody•13mo ago

what languages do you need made available, other than java

Kurdiez•13mo ago

Only Java

Brody•13mo ago

what version

Kurdiez•13mo ago

Brody•13mo ago

do you need anything else in the container?

Kurdiez•13mo ago

no Just need Java that's all

Brody•13mo ago

would that just be jre?

Kurdiez•13mo ago

Yes just JRE is ok

Brody•13mo ago

untested, but add this to a railway.json file in your project

{
  "$schema": "https://schema.up.railway.app/railway.schema.json",
  "build": {
    "builder": "NIXPACKS",
    "nixpacksPlan": {
      "providers": [],
      "phases": {
        "setup": {
          "nixPkgs": ["jdk17"]
        }
      }
    }
  },
  "deploy": {
    "restartPolicyMaxRetries": 3,
    "startCommand": "bin/run.sh /app/apps/ib-client-portal/root/config.yaml"
  }
}

}

Kurdiez•13mo ago

Root folder of my project?

Brody•13mo ago

if thats what you have railway deploying from, yes

Kurdiez•13mo ago

It's a monorepo that will have many things deployed from. This Java server is one of them. How can I make it so that only one service is using this railway.json configuration. All the other services don't need Java at all

Brody•13mo ago

are they in subfolders?

Kurdiez•13mo ago

Yeah

Brody•13mo ago

have you set a root directory for this railway service?

Kurdiez•13mo ago

yes that root directory is the subfolder where this Java server is in

Brody•13mo ago

what did you set it to?

Kurdiez•13mo ago

/apps/ib-client-portal This is the root folder that's set in the settings of the service

Brody•13mo ago

then that is where you should put that railway.json file

Kurdiez•13mo ago

ok thank you. testing it out now

This showed up in build log so far. So I guess that's good.

Brody•13mo ago

indeed

Kurdiez•13mo ago

Well build was successful and deployment shows this log

I think this is an issue I should solve myself. My start command is bin/run.sh root/config.yaml where I pass the config.yaml but it can't find that config file...

Brody•13mo ago

where is the config file relative to the root of your entire project?

Kurdiez•13mo ago

- monorepo-root/apps/ib-client-portal/railway.json - monorepo-root/apps/ib-client-portal/bin/run.sh - monorepo-root/apps/ib-client-portal/root/config.yaml

Brody•13mo ago

should you have written monorepo-root? is that an actual folder within your projects root folder?

Kurdiez•13mo ago

no, i'm just letting you know the relative paths from my monorepo-root That is the root folder in Github repo basically

Brody•13mo ago

okay so you dont actually have a monorepo-root in your root, that is the name of the root folder on your computer?

Kurdiez•13mo ago

yes that's correct

Brody•13mo ago

ive updated this, please update your copy

Kurdiez•13mo ago

Thanks. trying it out
