# Cloud9

## Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>`:`<internal>` respectively. For example, `-p 8080:80` would expose `port 80` from inside the container to be accessible from the host's IP on `port 8080` outside the container
