# Build the application
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main ./cmd/twilio

# Second stage: create the final image
# Alpine is a minimalistic version of Linux suitable for Docker deployments, due to smaller attack surface,
# faster setup and such.
# BUT I historically had really hard time setting up more advanced libraries with it (as ffmpeg).
FROM alpine:latest

# Add CA Certificates
RUN apk --no-cache add ca-certificates

# Copy the pre-built binary file from the previous stage
COPY --from=builder /app/main .

# Expose port (if your app uses a port)
EXPOSE 8080

# Command to run the executable
CMD ["./main"]
