# Distroless is as the name implies, distroless. The entrypoint is `node`, and
# there is no shell. Therefore, the following command will not work:
#
#   CMD ["yarn", "start:prod"]
#
# Instead, we need to pass node the flags it needs to use PnP directly, as well
# as the script we want to run:

CMD ["--require", "./.pnp.cjs", "--experimental-loader", "./.pnp.loader.mjs", "dist/main.js"]
