In this lab you will be exposed to the VMware Tanzu Kubernetes Grid Integrated Management Console allowing you to quickly and easily deploy and manage clusters and nodes as part of your Kubernetes cluster running on TKGI. This lab leverages Module 6 from the TKGI 2131 Hands On Lab. 2131 Lab Module List: • Module 1 - Introduction to Kubernetes (45 minutes) (Advanced) You will learn what container orchestration with Kubernetes is all about. Terminology is a barrier to understanding technology and the fundamental components of the Kubernetes platform will be explained in detail. This module contains no lab steps but will provide you with a foundational understanding that will make the other modules more intuitive. • Module 2 - Introduction to Tanzu Kubernetes Grid Integrated (TKGI) (45 minutes) (Advanced) Operationalizing Kubernetes at scale is not for the faint of heart. TKGI is a purpose built service to deploy and manage Kubernetes clusters. This module will introduce TKGI, showing the capabilities to extend High Availability, scale, health monitoring and lifecycle management to Kubernetes. • Module 3 - Kubernetes Deep Dive (45 minutes) (Advanced) This module is pure Kubernetes lab work. You will use the kubectl CLI to manipulate the Kubernetes components you read about in Module 1. You will create the deployment that defines the pods and services that make up your nginx webserver application. You will scale the application both up and down - adding pods to provide either increased capacity or availability. By the end you should be very comfortable with manipulating your application components through the CLI. • Module 4 - Deploy and Manage Multi-tiered Application (30 minutes) (Advanced) This module can be taken independently from the first two, but builds on the knowledge gained there to deploy a more complex application. You will see the components of a web-based restaurant rating system application that includes a backend database. Once your application is deployed, you will upgrade to a newer version with no downtime, and will subsequently roll the upgrade back - again without downtime. • Module 5 - TKGI Octant Dashboard (30 minutes) (Advanced) This module can be taken independently from other modules however since it provides visibility into your Kubernetes cluster it's beneficial to have taken Modules 3 and 4 to have some meaningful data to review in the dashboard. HOL-2131-91-MAP Page 3 HOL-2131-91-MAP In this module you will be introduced to Octant,an open source developer- centric web interface for Kubernetes that lets you inspect a Kubernetes cluster and its applications. • Module 6 - Tanzu Kubernetes Grid Integrated Management Console - (30 minutes) (Advanced) This module can be taken independently from other modules since it does not depend on any of the pods which you will be creating in Modules 3 and 4. This module introduces you to the capabilities of the Tanzu Kubernetes Grid Integrated Management Console, a new feature in this release of TKGI the management console provides a GUI for managing users, viewing the clusters and nodes and performing updates on TKGI.Introduction to The Kubernetes UI And Monitoring • (30 minutes) (Advanced)Dashboard is a web-based Kubernetes user interface. You can use Dashboard to deploy containerized applications to a Kubernetes cluster, troubleshoot your containerized application, and manage the cluster resources. You can use Dashboard to get an overview of applications running on your cluster, as well as for creating or modifying individual Kubernetes resources (such as Deployments, Jobs, DaemonSets, etc). For example, you can scale a Deployment, initiate a rolling update, restart a pod or deploy new applications using a deploy wizard. Dashboard also provides information on the state of Kubernetes resources in your cluster and on any errors that may have occurred. Prometheus is a popular metrics collecting application, Prometheus is used to collect metrics from Kubernetes Cluster, Nodes, Pods and Services and export the Metrics. The Prometheus dashboard is very metrics driven so frequently Prometheus is used with the Grafana Metrics UI to provide a more visual, dashboard driven view of the data collected by Prometheus and other metrics agents. • Module 8 - Using Log Insight With TKGI - (15 minutes) (Advanced) VMware vRealize Log Insight gives administrators the ability to consolidate logs, monitor and troubleshoot vSphere and third-party infrastructure, and perform security auditing, compliance testing, log querying, aggregation, correlation, and retention. The vRealize Log Insight virtual appliance includes a syslog server, log consolidation tool, and log analysis tool that will work for any type of device that can send syslog data. vRealize Log Insight administrators can also create custom dashboards based on saved queries that can be exported, shared, and integrated with TKGI gives administrators the ability to view kubernetes constructs as well. • Module 9 - VMware Tanzu Modern Applications Ninja Program - (15 minutes ) This module is independent of any module in this lab, it connects you to some outside resources where you can sign up for the VMware Modern Applications Ninja Program, this effort originated as a internal VMware training program and has now expanded it's scope to allow anybody to join. The VMware Modern Applications Ninja Program provides educational resources as well as a forum to communicate with VMware Modern Applications engineers and other people in the Modern Applications Community Lab Captain: HOL-2131-91-MAP Page 4 HOL-2131-91-MAP • Kevin Brady, Sr. Partner Solution Engineer, USA This lab manual can be downloaded from the Hands-on Labs Document site found here: http://docs.hol.vmware.com This lab may be available in other languages. To set your language preference and have a localized manual deployed with your lab, you may utilize this document to help guide you through the process: http://docs.hol.vmware.com/announcements/nee-default-language.pdf If you have taken other Hands On Labs feel free to skip the remainder of this section and proceed to the next section of this module. Location of the Main Console 1. The area in the RED box contains the Main Console. The Lab Manual is on the tab to the Right of the Main Console. 2. A particular lab may have additional consoles found on separate tabs in the upper left. You will be directed to open another specific console if needed. 3. Your lab starts with 90 minutes on the timer. The lab can not be saved. All your work must be done during the lab session. But you can click the EXTEND to increase your time. If you are at a VMware event, you can extend your lab time twice, for up to 30 minutes. Each click gives you an additional 15 minutes. HOL-2131-91-MAP Page 5 HOL-2131-91-MAP Outside of VMware events, you can extend your lab time up to 9 hours and 30 minutes. Each click gives you an additional hour. Alternate Methods of Keyboard Data Entry During this module, you will input text into the Main Console. Besides directly typing it in, there are two very helpful methods of entering data which make it easier to enter complex data. Click and Drag Lab Manual Content Into Console Active Window You can also click and drag text and Command Line Interface (CLI) commands directly from the Lab Manual into the active window in the Main Console. Accessing the Online International Keyboard You can also use the Online International Keyboard found in the Main Console. 1. Click on the Keyboard Icon found on the Windows Quick Launch Task Bar.

The "@" sign is Shift-2 on US keyboard layouts. 1. Click once in the active console window. 2. Click on the Shift key. Click on the @ key 1. Click on the "@ key". Notice the @ sign entered in the active console window. HOL-2131-91-MAP Page 7 HOL-2131-91-MAP Activation Prompt or Watermark When you first start your lab, you may notice
