Extreme Campus Controller supports container applications that oer custom solutions for network
management. Applications are installed as .Docker files available on Extreme Networks support site or
downloaded from the Docker hub.
Note
You can install the application from a local image file or you can download an image file from
Docker Hub. Before an image file is downloaded from Docker Hub, Extreme Campus
Controller checks the image version. When a newer version is available, a message is
displayed on the Extreme Campus Controller user interface. Extreme Campus Controller does
not download information from Docker Hub. It only checks the application version.
Extreme Campus Controller supports integration with Amazon Greengrass. Therefore, it
periodically checks availability of the service. Extreme Campus Controller does not upload or
download information to and from these services.
Communication from Extreme Campus Controller to Docker Hub or AWS can be blocked on
the firewall. When communication is blocked, the application continues to operate normally,
but you will not be notified when a newer image file is available on Docker Hub.
Note
A Domain Name Server (DNS) is required when deploying container applications because the
application logic may require access to external resources (such as the Docker Repository).
For information about configuring a Domain Name Server (DNS), see the Extreme Campus
Controller Deployment Guide.
