+# 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 ...`.
