To Improve the distribution of PODs to the least number of kubernetes worker nodes who is Required but also to secure that the PODs of one Deployment are distributed over the Fault Zones and Node pools the pod affinity and anti affinity are set. Affernety number calculation: Assign Number for an host = 0 - 20 X Fault Zone - 10 X Node Pool + 9 X Host Host = 1 if on the host runs an POD from the Schulcloud-Verbund on any namespace Host = 0 if on the host runs no POD from the Schulcloud-Verbund on any namespace Node Pool = 1 if on a host of this node pool runs an POD from the Deployment Node Pool = 0 if on no host of this node pool runs an POD from the Deployment Fault Pool = 1 if on a host of this fault zone runs an POD from the Deployment Fault Pool = 0 if on no host of this fault zone uns an POD from the Deployment

Description
To Improve the distribution of PODs to the least number of kubernetes worker nodes who is Required
but also to secure that the PODs of one Deployment are distributed over the Fault Zones and Node pools
the pod affinity and anti affinity are set.
Affernety number calculation:
Assign Number for an host = 0 - 20 X Fault Zone - 10 X Node Pool + 9 X Host
Host = 1 if on the host runs an POD from the Schulcloud-Verbund on any namespace
Host = 0 if on the host runs no POD from the Schulcloud-Verbund on any namespace
Node Pool = 1 if on a host of this node pool runs an POD from the Deployment
Node Pool = 0 if on no host of this node pool runs an POD from the Deployment
Fault Pool = 1 if on a host of this fault zone runs an POD from the Deployment
Fault Pool = 0 if on no host of this fault zone uns an POD from the Deployment
