Hey there! We've found the following might help you get unblocked faster:

• 🧵 Dockerfile Path

• 🧵 Docker build context completely empty when using UI-configured Dockerfile path

• 🧵 Subject: Issue Deploying FastAPI Backend on Railway with Docker

If you find the answer from one of these, please let us know by solving the thread!

Is there a Dockerfile at api/Dockerfile in your repository?

No

I resolved it like this i've to forcefully create a dockerfile at api/Dockerfile like this below then it also railway.toml file [build]

builder = "DOCKERFILE"

[deploy]

restartPolicyType = "ON_FAILURE"

restartPolicyMaxRetries = 10

FROM node:20-alpine

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

RUN npm run build

EXPOSE 5060

CMD ["npm", "start"]

You had your root directory set to /api and your builder set to "DOCKERFILE" so we looked for a Dockerfile at /api/Dockerfile.

Good to hear you solved it, but Railway normally won't try to use a non-existant Dockerfile if you didn't configure it yourself. Do you have any root directories configured in Service > Settings > Source?

oh i see, I just checked you're right builder was set for the "DOCKERFILE"
