| # docker-node-sass | ||||
|  | ||||
| Docker image for node-sass, based on this blog post: | ||||
| http://johnbokma.com/blog/2021/06/17/a-docker-image-for-sass.html | ||||
|  | ||||
| ## Run with Docker | ||||
|  | ||||
| `docker run -v "$(pwd):/data" 3wordchant/node-sass main.scss` | ||||
|  | ||||
| `-v ...` mounts the current directory into the `/data` directory, which is where | ||||
| `sass` will look for files. If your SCSS files are elsewhere, you can change or | ||||
| add to `"$(pwd)"` | ||||
|  | ||||
| Everything after `3wordchant/node-sass` is an argument to the Sass compiler. See | ||||
| all available options by running `... 3wordchant/node-sass --help`. | ||||
|  | ||||
| In particular, the `-w` "watch" option might be helpful, e.g.: | ||||
|  | ||||
| `docker run -v "$(pwd):/data" 3wordchant/node-sass -w main.scss main.css` | ||||
|  | ||||
| will watch for changes to `main.scss` or its dependencies, and compile them to | ||||
| `main.css`. | ||||
|  | ||||
| ## Run with docker-compose / Docker Swarm-mode | ||||
|  | ||||
| ``` | ||||
| services: | ||||
|   sass: | ||||
|     image: 3wordchant/node-sass | ||||
|     volumes: | ||||
|       - "../path/to/assets:/data" | ||||
|     command: ["-w", "scss/main.scss", "css/main.css"] | ||||
| ``` | ||||
|  | ||||
| You can also then run one-off commands with `docker-compose exec sass ...`. | ||||
