Infrastructure requirements

This section lists the infrastructure requirements for the Mirantis OpenStack for Kubernetes (MOSK) reference architecture.

Infrastructure requirements
Service	Description
MetalLB	MetalLB exposes external IP addresses of cluster services to access applications in a Kubernetes cluster.
DNS	Application Gateway, managed by the Envoy Gateway controller, is used to expose OpenStack services outside of a Kubernetes deployment. Access to these services is allowed only by their FQDN. Therefore, DNS is a mandatory infrastructure service for an OpenStack on Kubernetes deployment.
