To deploy OVA on VMware platform using ansible a provision server is required from where ansible playbooks need to be executed. Follow the steps as mentioned in  how to build ansible provision server for VMware  and make the provision server ready. With the help of vmware_deploy_ovf  module ansible can deploy VMware OVA. Let say the requirement is to deploy the OVA in a vm folder and under a resource pool in hosts view, then it should go through the following check points: Create vm folder and resource pool if not present OVA should be available in the provision server Before deploying the OVA, extract the OVA and check the custom section of .ovf file to see what all variable need to pass in the playbook at the time of deployment. We will create three yml files to keep: vmware ova deployment code ( vsphere_ova_deploy.yml ) vmware environment login details ( vsphere_creds.yml ) variables used for the guest deployment ( vsphere_var.yml ) In my example, I have t

To deploy VMware guest using ansible a provision server is required from where ansible playbooks need to be executed. Follow the steps as mentioned in  how to build ansible provision server for VMware  and make the provision server ready. We will create three yml files to keep: vmware guest deployment code ( vsphere_guest_deploy.yml ) vmware environment login details ( vsphere_creds.yml ) variables used for the guest deployment ( vsphere_var.yml ) This vsphere_guest_deploy.yml playbook will perform the following tasks: Make sure to have a template in the vCenter Server VM need to be deployed in a dedicated vm folder and resource pool VM folder and resource pool will be created if not available For this deployment an application user is needed in vCenter which should have required privilege to perform all the above tasks.  Content of vCenter credentials yml file: Content of vCenter variable file: Content of vmware guest deployment yml:

Ansible is a great automation tool for infrastructure as a code and using ansible modules to automate VMware platform is really easy. In order to start the automation, need to configure a provision server where ansible and some of its dependencies need to be installed. A provision server can be on any operating system. But in this document we have focused on the following two opensource operating systems: Ubuntu 20.04 LTS CentOS 8.x  Following steps need to be performed to configure Ubuntu 20.04 LTS as a provision server: a. Install python3-pip:     # apt-get  install  python3-pip  -y    Upgrade pip3 to the latest version:   # pip3  install  --upgrade  pip b. Install & check latest ansible  version:       # pip3 install ansible   # pip3 show ansible      c.  Install & check  pyVmomi :       # pip3 install pyvmomi   # pip3 show pyvmomi Following steps need to be performed to configure CentOS 8.x as a provision server: a.
