+# cups
+Common Unix Printing System (CUPS), is the most widely used printing system on Linux
+systems. CUPS allows you to use, manage and share many printers on the network,
+as it is designed as a client/server system.
+
+This repository contains only build scripts for the CUPS daemon.
+
+## Usage
+To start cups directly over cli:
+
+```bash
+docker run \
+  --detach \
+  --env CUPS_ADMIN_USER=print \
+  --env CUPS_ADMIN_PASSWD=print \
+  --network=host \
+  --volume /var/run/dbus:/var/run/dbus \
+  --name cupsd \
+  volkerraschek/cupsd
+```
+
+or if you want to use a `docker-compose.yml`
+
+```yaml
+version: '3'
+services:
+  cupsd:
+    container_name: cupsd
+    environment:
+      - CUPS_ADMIN_USER=print
+      - CUPS_ADMIN_PASSWD=print
+    network_mode: host
+    restart: always
+    volumes:
+      - /var/run/dbus:/var/run/dbus
+```
+
+After starting the container, cups is available over http://localhost:631
