I have a Node.js application but I wanted to use my own Dockerfile. I need to use BuildKit's Build Secrets. How do I assign the build secret in railway builds?

Is there a secure workaround or does it basically mean that I can't use a Dockerfile if I want to install an NPM package from a private registry, for instance?

Hey, if you want to use environment variables at build time in a Dockerfile, be sure to use it like this:

# Specify the variable you need

ARG RAILWAY_SERVICE_NAME

# Use the variable

RUN echo $RAILWAY_SERVICE_NAME

Be sure to declare your environment variables in the stage they are required in.

The problem with ARGS is that they get baked into the image.
