How to fixAt the end of your Dockerfile, add a CMD or ENTRYPOINT to tell Docker which binary to run when the container starts.Since you’ve built your Go backend into a binary named main, you should run that: # Stage 3: Production imageFROM ubuntu:22.04WORKDIR /app# Install ca-certificates for HTTPS requestsRUN apt-get update && \apt-get install -y ca-certificates tzdata && \rm -rf /var/lib/apt/lists/*# Copy the backend binaryCOPY --from=backend-build /app/main .# Copy the frontend buildCOPY --from=frontend-build /app/dist ./static# Make binary executableRUN chmod +x ./main# Use Railway's $PORT environment variableEXPOSE 8080# Tell Docker what to run when container startsCMD ["./main"]
