7. What’s Rancher ? • Kubernetes management platform for building and operating Kubernetes cluster, importing existing Kubernetes cluster, regardless of cloud or on-premise and multi-cloud or hybrid-cloud • Application management with helm-based catalog function • Kubernetes management linked with OSS such as GitLab, Prometheus, Fluentd • Development is Rancher Labs（http://rancher.com/） • Open source software (with paid version with support)

13. Google announces new service "Anthos" Kubernetes Clusters Create Import EKS GKE AKS vSphere Bare Metal Create,Import,Manage Kubernetes Clusters !! Manage Kubernetes is becoming the Linux of the cloud by Jim Zemlin （The Linux Foundation） Multi Cloud to Multi Kubernetes CloudNtive to KubernetesNative A platform for hybrid-cloud and multi-cloud that enables containerized applications to run anywhere on premises and in the cloud. Introducing Anthos: An entirely new platform for managing applications in today's multi-cloud world by Google Cloud Blog 2019.4.10
14. Rancher Labs Official Blog This is super exciting news for Rancher. In Google Anthos, we see great alignment with Rancher’s vision. We believe Kubernetes will become the standardized infrastructure provided by all public and private clouds, and an enterprise Kubernetes platform must deliver multi-cluster, multi-cloud management. http://bit.ly/rancher_blog_anthos

36. Rancher on kubernetes
37. Rancher High Availability & Single Node Installation 1.High Availability Installation High Availability Installation installs Rancher on your Kubernetes cluster. Establish high availability with the features of Kubernetes. Recommended for production environments that operate 24/365. • DNS for Rancher should resolve to a Layer 4 load balancer (TCP) • The Load Balancer should forward port TCP/80 and TCP/443 to all 3 nodes in the Kubernetes cluster. • The Ingress controller will redirect HTTP to HTTPS and terminate SSL/TLS on port TCP/443. • The Ingress controller will forward traffic to port TCP/80 on the pod in the Rancher deployment. L4 Load Balancer (TCP)
38. Rancher High Availability & Single Node Installation 2.Single Node Installation Single Node Installation installs Rancher on a single Linux host. It is recommended for development and test environments as it is very easy to set up. Step 2: Start the server $ sudo docker run -d --restart=unless-stopped -p 80:80 -p 443:443 rancher/rancher Web Access!! https://<server_ip>/ Step 1: Prepare a Linux Host OS Hardware Docker Ubuntu 16.04 (64-bit) Small: vCPUs 1 MEM 4GB Up to 5(Clusters) Medium: vCPUs 2 MEM 8GB Up to 10(Clusters) 17.03.x, 18.06.x, 18.09.x Ubuntu 18.04 (64-bit) 18.06.x, 18.09.x Red Hat Enterprise Linux (RHEL)/CentOS 7.6 (64-bit) RHEL Docker 1.13 17.03.x, 18.06.x, 18.09.x RancherOS 1.5.1 (64-bit) 17.03.x, 18.06.x, 18.09.x Windows Server version 1803 (64-bit) 17.06
39. Rancher High Availability & Single Node Installation 3.Structure of Single Node Installation When Rancher generates its own Kubeconfig file, it will build an external Kubernetes if Kubeconfig file is passed from outside, an internal Kubernetes if it already has an internal Kubeconfig file, and a new internal Kubernetes otherwise. It is working. External Kubernetes is a pattern of external Kubernetes clusters running Rancher in a high availability installation. On the other hand, internal Kubernetes are called embedded kubernetes, and if it is judged that Kubernetes will continue to run indefinitely but there is no Kubernetes to operate, they will be the embedded Kubernetes that Rancher acts as Kubernetes. For details on the embedded logic of Embedded Kubernetes, see here !! (https://github.com/rancher/rancher/blob/v2.1.5/pkg/embedded/embedded.go#L36).

68. Rancher In The Future
69. Kubernetes, Istio, Knative,Service Mesh like “docker run” Rio is a Kubernetes-based MicroPaaS https://rio.io/ At Rancher Labs, all of our products are focused on making Kubernetes simple to use for everybody. Even still, our teams were frustrated by how much effort is required to manage tools like Istio and Knative. We built Rio so developers could deploy, manage, scale, and version their applications with a single command.
70. Rancher In The Future Phase1:Deliver a full-featured container management platfrom that integrates the cloud native technologies and ecosystem Phase2:Intorduce multi-cluster management and multi-cluster applications Phase3:Expand Kubernetes footprint everywhere(cloud,data center, and edge) Sponsored Session: The Journey to Kubernetes Everywhere - Shannon Williams, Rancher Labs Presentation Docs : http://bit.ly/k8sday_india_rancher Presentation Movie : http://bit.ly/k8sday_india_rancher_movie
