/analysis/containers/kubernetes/<analysisId>/systems resource is used to return a collection of all container systems that were included in the Kubernetes optimization analysis.
The number of analyzed systems (i.e. /containers/kubernetes/<analysisId>/systems entities) will always be greater than or equal to the number of system recommendations produced (i.e. /containers/kubernetes/<analysisId>/results entities), as some systems may not have any recommendations. See Analysis: Kubernetes Container Recommendations for details of the Kubernetes container recommendation resource.
