+# Multi-camera with Docker
+
+If you own multiple IP-cameras, then you probably **don't want** to setup **a Raspberry Pi for each camera**. Thanks to Docker there is an easier approach: instead of running multiple machines you can run multiple containers on a single machine. And when you're processing a lot of cameras, you can **distribute the cameras/containers across multiple machines** by using **Docker Swarm**.
+
+## This is how it goes..
+
+The approach is equal to [**the traditional Docker approach**](/installation/docker). First you need to make sure you have **Docker installed** on the machine(s) you prefer. After the installation you can use docker-compose to get Kerberos.io up and running. Create a **docker-compose.yml** file and add following configuration:
+
+    machinery:
+        image: kerberos/machinery
+        ports:
+        - "8889"
+
+    web:
+        image: kerberos/web
+        ports:
+        - "80"
+        volumes_from:
+        - machinery
+        links:
+        - machinery
+
+Instead of running docker-compose up, we add an additional parameter **-p**. This will create and link the containers from the compose file, but will **wrap and isolate** the containers **in a project**. By reusing this command, and defining different project names, you can run multiple Kerberos.io instances on the same machine (or distribute them over multiple machines.)
