Hello, any help on this issue?

hello! can you try to switch to railpack in your railway.json file

Hi, I changed it to railpack and added custom install command, but while nixpack installed it (playwright install), railpack didn't. here is my railway.json file

{
"$schema": "https://railway.app/railway.schema.json",
"build": {
"builder": "RAILPACK",
"nixpacksPlan": {
"phases": {
"setup": {
"nixPkgs": [
"python3",
"gcc"
]
},
"install": {
"dependsOn": [
"setup"
],
"cmds": [
"pip install -r requirements.txt",
"python -m playwright install --with-deps chromium"
]
}
}
}
},
"deploy": {
"startCommand": "hypercorn main:app --bind \"[::]:$PORT\""
}
}

i hope you can see the issue there, you set the builder to railpack, and then tried to use nixpacks config

Sorry, my bad. But I don't see any the corresponding key for railpack in schema.json (such as railpackPlan).

I've also tried to add RAILPACKINSTALLCMD=pip install -r requirements.txt && python -m playwright install --with-deps chromium and change railway.json to
{ "$schema": "[https://railway.app/railway.schema.json](https://railway.app/railway.schema.json)", "build": { "builder": "RAILPACK" }, "deploy": { "startCommand": "hypercorn main:app --bind \"[::]:$PORT\"" } }
But it didn't run custom install command

try adding this to a railpack.json file -

{
  "$schema": "https://schema.railpack.com",
  "steps": {
    "playwright": {
      "inputs": [{ "step": "install" }],
      "commands": ["python -m playwright install --with-deps chromium"]
    }
  },
  "deploy": {
    "inputs": ["...", { "step": "playwright" }]
  }
}

I got this error:

`✕ python -m playwright install --with-deps chromium
process "sh -c python -m playwright install --with-deps chromium" did not complete successfully: exit code: 1

✕ docker-image://ghcr.io/railwayapp/railpack-runtime:latest
failed to do request: Head "https://ghcr.io/v2/railwayapp/railpack-runtime/manifests/latest": context canceled: context canceled`

And Do I have to keep both railway.json and railpack.json (in the setting, I'm setting the path to railway.json)?

I'm not a technical person, so sorry if i ask stupid question.

When I try to access the link: https://ghcr.io/v2/railwayapp/railpack-runtime/manifests/latest, I got error: {"errors":[{"code":"UNAUTHORIZED","message":"authentication required"}]}

I checked the deployment log and saw it runs "playwright install" successfully. But when I ran my application, I saw this error in the logs:

Although, in the build logs, I saw that Playwright was downloaded to this path

@jr - when you have a moment, do you have an idea on how you would include what playwright has installed in the deploy image?

You need to specify the directory to include (the warning is being swalled and not included in the build logs). This should work

{
  "$schema": "https://schema.railpack.com",
  "provider": "python",
  "steps": {
    "playwright": {
      "inputs": [{ "step": "install" }],
      "commands": ["python -m playwright install --with-deps chromium"]
    }
  },
  "deploy": {
    "inputs": [
      "...",
      {
        "step": "playwright",
        "include": ["/root/.cache"]
      }
    ],
    "startCommand": "hypercorn main:app --bind \"[::]:$PORT\""
  }
}

i was close

I'm iterating on this lately so this is good feedback

i had thought just specifying the step would also include its files

that would include all of the OS system files and I'm trying to avoid merge those because it is slow and can blow up the image

i see

but I can see how it is confusing. I'll experiment with somethings

Hi, I tried your config file, and then the build and deployment were successful. But I got this error when running the app

and here are the build logs

hmm it is because the playwright deps are not being installed in the runtime image. Can you try changing to

{
  "$schema": "https://schema.railpack.com",
  "provider": "python",
  "steps": {
    "playwright": {
      "inputs": [{ "step": "build" }],
      "commands": ["python -m playwright install --with-deps chromium"]
    }
  },
  "deploy": {
    "inputs": [{ "step": "playwright" }],
    "startCommand": "hypercorn main:app --bind \"[::]:$PORT\""
  }
}

Its not ideal, but it is something we can soon address in Railpack

It works now. Thanks a lot for your support!
