14 Installation Feature(s): Make the installer modular to allow playbooks to run independently. Description: The installer has been enhanced to allow admins to install specific components. How it Works: By breaking up the roles and playbooks, we allow for a better targeting of ad hoc administration tasks. Sample ordering of playbooks: playbooks/byo/openshift-checks/pre-install.yml playbooks/byo/openshift-etcd/config.yml playbooks/byo/openshift-nfs/config.yml (if required) playbooks/byo/openshift-loadbalancer/config.yml (if required) playbooks/byo/openshift-master/config.yml playbooks/byo/openshift-master/additional_config.yml playbooks/byo/openshift-node/config.yml playbooks/byo/openshift-glusterfs/config.yml (if required) playbooks/byo/openshift-cluster/openshift-hosted.yml playbooks/byo/openshift-cluster/openshift-metrics.yml (if required) playbooks/byo/openshift-cluster/openshift-logging.yml (if required) playbooks/byo/openshift-cluster/service-catalog.yml (if required) playbooks/byo/openshift-management/config.yml (if required)

15 Installation Feature(s): Both Install AND Configure CFME 4.6 from the OpenShift installer - To install CFME 4.6: Description: CloudForms 4.6 will be fully supported running on OCP 3.7 as a set of containers. - To configure CFME 4.6 to consume the OpenShift installation it is running on: # ansible-playbook -v -i <YOUR_INVENTORY> playbooks/byo/openshift-management/config.yml # ansible-playbook -v -i <YOUR_INVENTORY> playbooks/byo/openshift-management/add_container_provider.yml - You can also automate the configuration of the provider to point to multiple OpenShift clusters: How it Works: We have automated the installation experience to the level we have only done for metrics and logging in the past. Now management (CloudForms) is an available API endpoint on all OpenShift clusters that choose to use it. More cluster admins will be able to leverage CloudForms and begin experiencing the insight and automations available to them in the full OpenShift container platform. # ansible-playbook -v -e container_providers_config=/tmp/cp.yml playbooks/byo/openshift-management/add_many_container_providers.yml

16 Networking Feature(s): Network Policy Description: Optional plugin specification of how selections of pods are allowed to communicate with each other and other network endpoints. How it Works: Fine-grained network namespace isolation using labels and port specifications what ingress traffic is allowed to any pod, from any other pod on specific ports including traffic from pods located in other projects Policy applied to namespace: project-a kind: NetworkPolicy apiversion: extensions/v1beta1 metadata: name: allow-to-red spec: podselector: matchlabels: type: red ingress: - {}

17 DÉMO #2 17 Network Policy

18 Metrics Feature(s): Introducing Prometheus (Tech Preview) PS: Hawkular is still the supported Metrics stack Description: OpenShift Operators deploy Prometheus on an OCP cluster, collect Kubernetes and Infrastructure metrics, get alerts. Operators can see and query metrics and alerts on Prometheus web dashboard. Or They can bring their own Grafana and hook it up to Prometheus. How it Works: New OpenShift installer playbook for installing Prometheus (2.0) server, alert manager and oauth-proxy Deploys Statefulset comprising server, alert-manager, buffer and oauthproxy in front and a PVC one for server and one for alert manager Alerts can be created in a rule file and selected via inventory file
