classify resources and use selectors to find them and use them for certain actions. Replication Controller Replication Controllers (RC) are an abstraction used to manage pod lifecycles. One of key uses is important that it is replaced by a new one. To achieve this, Kubernetes uses a replication controller, which ensures that a certain number of replicas of a pod are always running. In cases where only screen, where we can add a host machine from some of public clouds or from a custom stack. In this example, we’ll choose the custom method. If you are still using the Vagrantfile from Git repo, set up three

PowerFlex Manager. It provides extensive automation capabilities with PowerFlex Manager REST APIs and custom Ansible modules to integrate with your infrastructure, application, and DevOps workflows. PowerFlex without having to compromise on performance and resiliency. PowerFlex is available through APEX custom solutions by the APEX Flex on Demand and APEX Datacenter Utility for customers looking to adopt management aggregation architecture: Note: There is an additional 1 Gb link from the PowerFlex controller nodes to the out-of-band management switch.

4 - Configure controller options Profile Applicability Rancher_Hardening_Guide.md 11/30/2018 12 / 24 Level 1 Description Set the appropriate arguments on the Kubernetes controller manager. Rationale Rationale To address the following controls the options need to be passed to the Kubernetes controller manager. 1.3.1 - Ensure that the --terminated-pod-gc-threshold argument is set as appropriate (Scored) (Scored) Audit On nodes with the controlplane role inspect the kube-controller-manager container: docker inspect kube-controller-manager Verify the following options are set in the command section:

(Automated) 1.1.3 Ensure that the controller manager pod specification file permissions are set to 644 or more restrictive (Automated) 1.1.4 Ensure that the controller manager pod specification file ownership root:root (Automated) 1.1.17 Ensure that the controller-manager.conf file permissions are set to 644 or more restrictive (Automated) 1.1.18 Ensure that the controller-manager.conf file ownership is set to root:root 2.35 Ensure that the API Server only makes use of Strong Cryptographic Ciphers (Automated) 1.3 Controller Manager 1.3.1 Ensure that the --terminated-pod-gc-threshold argument is set as appropriate (Automated)

directly support PodSecurityPolicies and instead provides a proprietary resource called a Policy Controller that implements similar functionality. 3.2.3 Configurable Adherence to CIS Security Benchmarks they direct users to manual scans using the open source kube-bench utility. Google offers a custom benchmark for GKE derived from the CIS Kubernetes Benchmark and accounts for the shared responsibility workflows effectively at scale. Any changes made to clusters go through the centralized Fleet controller, which contains access to the Git repository and the configurations and assignments of clusters
