You can deploy the Firewall Threat Defense container (FTDc) in open source Docker and Kubernetes environments. A container is a software package that bundles up code and associated requirements such as system libraries, system tools, default settings, and runtime, to ensure that the application runs successfully in a computing environment. From version 10.0, you can deploy the FTDc in an open source Docker and Kubernetes (K8S) environments. In this solution, the FTDc is integrated with the Container Network Interface (CNI) and is deployed as an Infrastructure-as-Code (IaC) solution. The integration with CNI provides improved flexibility in deployment of network infrastructure.
