How to split the build process from 1 repo and deploying 2 different services?

I am trying to deploy (1 node, and 1 go) service. And I have a Dockerfile for deploying the Node service. But, now the go service is also using the same Dockerfile. I prefer to use the Config As Code option, instead of using UI settings.

I saw the railway.json option, my question is that can I have two of them. One for node and other for go service? Project ID: 8fc2ad89-714b-4cb3-9778-cb64d1373409

you can have two yes, but first can you tell me about your file structure?

YashuOP•6mo ago

It's kind of messy structure, as of now.

/app
 // all go code
/src
 // all node code
/package.json
/pnpm-lock.yaml
/Dockerfile

/app
 // all go code
/src
 // all node code
/package.json
/pnpm-lock.yaml
/Dockerfile

Did I missed any file, which needs to be mentioned?

Brody•6mo ago

looks easy enough to deploy, do you already have two blank railway services

YashuOP•6mo ago

I have a node service already running on prod. Now, I am trying to add a go service.

Brody•6mo ago

and that Dockerfile, that's for the go app right? it has nothing to do with node?

YashuOP•6mo ago

That Dockerfile is for the node

Brody•6mo ago

do you have a dockerfile for the go app, or are you going to let nixpacks try and build it?

YashuOP•6mo ago

It would be nice to use Docker. What I can try is to have two railway.json file. For example - railway.node.json in (src directory) - railway.go.json in (app directory) Will something like this work? Just a rough idea 🤷‍♂️

Brody•6mo ago

yes it can work, but I don't currently see a need for the difference of names, but one thing at a time here. do you have a Dockerfile for the go app? or have you yet to write one?

YashuOP•6mo ago

I have yet to write one

Brody•6mo ago

in the mean time, do you think nixpacks would be able to build your go app?

YashuOP•6mo ago

I was able to run 2 different services from single repo, using railway.json file. Thanks for the help. 🙂

Brody•6mo ago

no problem!

Continuing on the same ticket. Now, I ran into similar issue. Where I have set the app sleep to disable for production, but how can I enable it for non-production environment. Since I ham using railway.json file, I am not able to modify the settings manually for non-prod env. I tried looking into the docs, for PR Environment Overrides

{
  "environments": {
    "pr": {
      "deploy": {
        "startCommand": "echo 'start command for all pull requests!'"
      }
    }
  }
}

{
  "environments": {
    "pr": {
      "deploy": {
        "startCommand": "echo 'start command for all pull requests!'"
      }
    }
  }
}

But railway.json schema is not showing any linting for this object.

Brody•6mo ago

yeah it doesn't have schema validation for this, but it should still work.. does it not work?

YashuOP•6mo ago

I am getting this error in the railway dashboard.

Failed to parse JSON file railway.node.json: invalid character '}' looking for beginning of object key string

Failed to parse JSON file railway.node.json: invalid character '}' looking for beginning of object key string

The actual config, I used.

  "environments": {
    "testing": {
      "deploy": {
        "sleepApplication": true
      }
    }
  }

  "environments": {
    "testing": {
      "deploy": {
        "sleepApplication": true
      }
    }
  }

Here testing is an environment in railway not a PR branch name from git.

Brody•6mo ago

that's your full railway.json?

YashuOP•6mo ago

Here's the full json file.

{
  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "DOCKERFILE",
    "dockerfilePath": "node.Dockerfile",
    "buildEnvironment": "V2"
  },
  "deploy": {
    "runtime": "V2",
    "numReplicas": 1,
    "sleepApplication": false,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  },
  "environments": {
    "testing": {
      "deploy": {
        "sleepApplication": true
      }
    }
  }
}

  "$schema": "https://railway.app/railway.schema.json",
  "build": {
    "builder": "DOCKERFILE",
    "dockerfilePath": "node.Dockerfile",
    "buildEnvironment": "V2"
  },
  "deploy": {
    "runtime": "V2",
    "numReplicas": 1,
    "sleepApplication": false,
    "restartPolicyType": "ON_FAILURE",
    "restartPolicyMaxRetries": 10
  },
  "environments": {
    "testing": {
      "deploy": {
        "sleepApplication": true
      }
    }
  }
}

I'll have to do some testing and get back to you
