Build with Docker or Podman
If you use Docker, replace podman with docker in the following commands.
Prepare the container
Download a small node container:
podman pull docker.io/library/node:lts-alpine
Use the container
Go to CreamCSS project's root directory and, to build the minimized files, execute:
podman run -it --rm -v "${PWD}":/app:Z -w /app node:lts-alpine build_CreamCSS.js
Cleanup
Remove the downloaded image:
podman rmi docker.io/library/node:lts-alpine
