- 3. Overview It’s time to automate the day to day vCenter Server’s administration tasks. A proper automation helps users to save time, avoid manual errors and makes things more simple and clean. Background: We have been given a task where we have to automate and orchestrate 3 tasks in our own home lab setup. It is up to us to choose the automation product but the given tasks need to complete and the workflows created should be functional. Requirement: As mention, the three requirements are summarized below Part.1: An automation workflows for a server deployment into a virtual data center. Must include a Windows server and an alternate OS such as RedHat, CentOS, Ubuntu or a Linux alternative. Part.2: An application workflow to deploy a web server into each of the servers from Part 1, and within each web server you will deploy a “Hello World” application using any programming language. Part.3: An orchestration workflow to publish an application or server to a cloud environment which could include vCloud, vCHS, AWS, Rackspace or a public or hybrid cloud environment. Home Lab Setup: I have an assembled desktop with not so high configuration, as summarized below
- 4. Hardware Specifications: Attribute Specification Processor AMD FX(tm)-8350 Eight-Core Processor, 4000 Mhz, 4 Core(s), 8 Logical Processor(s) Installed Physical Memory (RAM) 16.0 GB BIOS Version/Date American Megatrends Inc. 1302, 11/14/2012 OS Name Microsoft Windows 8 Enterprise Evaluation Version 6.2.9200 Build 9200 HDD Size 1 TB Software Specifications: Attribute Specification Hosted Virtualization Vmware Workstation 9 Host ESXi 5.1 Build - 1065491 Management vCenter Server 5.1 Automation vCenter Server Orchestrator Cloud vCloud Director 5.1 (incomplete Setup) DC Windows Server 2012 VMs for test Server 2008 R2, RHEL 6 worksation and Server Edition, Windows 7 All the ESXi hosts are running with same build and with local storage only. The vCloud Director is an Appliance which is deployed for testing purpose to fulfil one of the requirement. When vCenter Server is installed, it silently install vCenter Server Orchestrator. vCenter Server, vCenter Server Orchestrator and vCloud Director is using bundled SQL 2008 Express Database Edition. Domain Controller is configured on Server 2012. To fulfil the mentioned requirements, I am using Windows Server 2008 R2 and RHEL 6 Server Edition. Also, Windows 7 and RHEL 6 Workstation Edition is also deployed. Here is how the Lab environment looks
- 5. Due to the unavailability of shared storage, several vCenter Distributed features are not enabled. Lab video available at http://youtu.be/n-dGb1SWLHM Part 1: An automation workflows for a server deployment into a virtual data center. Must include a Windows server and an alternate OS such as RedHat, CentOS, Ubuntu or a Linux alternative. I would be deploying Windows Server 2008 and RHEL 6 automatically using vCenter Server Orchestrator. I have prepared two Gold Virtual Machines which would be cloned for automatic Server Deployments. Here are the steps 1. Separate Workflows created to clone the Gold Virtual Machines. One for Windows Virtual Machine and second for RHEL Virtual Macine. If the Workflow is run, it will only ask for New Virtual Machine name, remaining all the inputs are configured as attributes. 2. To make this workflow simpler for users, both the Workflows are combined using a simple scriptable task and a decision making object. The script just maps the entered Virtual Machine name to respective cloning Workflow and the Decision making object select the appropriate cloning Workflow depending on the selection, i.e., Windows or Linux.
- 6. 3. The combined Workflow required just 2 inputs, Guest Operating type and the new Virtual Machine name and it will automatically deploy the Virtual Machine on the Virtual Data Center. 4. This workflow will clone the Gold Virtual Machine and deploy new Virtual Machine under Cloned Virtual Machines folder and on the vdm-GoldImages Datastore.

- 7. Part 2: An application workflow to deploy a web server into each of the servers from Part 1, and within each web server you will deploy a “Hello World” application using any programming language. Conceptual Workflow To deploy WebServer on Server 2008 R2, we need to install the Internet Information Server (IIS) Role from Server Manager. This can be automated by several ways, we could use a script to install or push some commands. I am using below command to install the default feature of IIS 7.0 through Package Manager “start /w pkgmgr /iu:IIS-WebServerRole;WAS-WindowsActivationService;WAS-ProcessModel; WAS-NetFxEnvironment;WAS-ConfigurationAPI” This command is taken from the below MS link http://www.iis.net/learn/install/installing-iis-7/installing-iis-from-the-command-line I am following the below steps: 1. Copy the above command in notepad and save it as win.bat. 2. Create a vCenter Orchestrator Workflow to copy the file from local machine to target machine (Windows Server 2008). 3. Create another Workflow to run this batch file which will configure the IIS. Similar steps would be followed on RHEL 6 Server to deploy WebServer. Actual Workflow: 1. Created batch file with the name win.bat. 2. The file is copied from VCO local machine to Cloned Windows Server 2008 (Windows- Final) using the below Workflow.
- 8. 3. Second Workflow is created to run the batch file in the Windows-Final Virtual Machine which will configure WebServer. 4. Create final Workflow and combine both the Workflow to automate the complete task. Similarly, for RHEL 6, the perl script can be prepared to download the httpd package and start the httpd service and same Workflow can be used to deploy.

- 9. Part. 3 Create an orchestration workflow to publish an application or server to a cloud environment which could include vCloud, vCHS, AWS, Rackspace or a public or hybrid cloud environment. Conceptual Workflow I am going ahead with the Workflow which will publish the Server to vCloud Director. As per the requirement, we need to deploy a vCloud Director Private Cloud to demonstrate this task. Below are the steps to accomplish this task 1. Deploy vCloud Director Appliance and configure it. 2. Install the vCloud Director Plugin for vCenter Server Orchestrator. Which comes with lot of default Workflows and Actions.
- 10. 3. The Workflow which is created will clone a Virtual Machine and transform that Virtual Machine into a vApp. Two Workflows are used, one to clone (Same Workflow used in the first task) and then Second to Import VM as vApp. The Second Workflow “Import VM as vApp” is the default Workflow which got added with vCloud Director Plugin. 4. After the successful completion of the Workflow, a New Virtual Machine is create with the clone process and deployed on to the vCloud Director’s Catalog as vApp. I was not able to setup the vCloud Director completely in my home lab setup as I realized lately that I am running out of resources and time. Hence, I wouldn’t be able to demonstrate the complete process of publishing. However, I would try to demonstrate as much I could on the vCenter Orchestrator workflow created. Find the detailed information about Workflow on the below PDF (Part3) Adobe Acrobat Document Please find the video for Part 3 http://youtu.be/vkqTWSTflgA Conclusion: With the above three tasks, it can be concluded that vCenter Orchestrator is very stable, user friendly Automation product which can be used to automate everyday work and save lot of time. There are more than 300 Workflow available within the VCO Library and more Workflows would be added as when you install new Plugins. This Automation Tool comes along with the vCenter Server Suite and gets installed silently and it doesn’t need much scripting knowledge and by combining multiple Workflows more complicated tasks could be easily achieved. Someone rightly said it is an “Undiscovered Country”.
