Environment variable support added in Ansible 2.6. If the value is not specified in the task, the value of environment variable VMWAREHOST will be used instead. You use vSphere Lifecycle Manager images to apply software and firmware updates to the ESXi hosts in a cluster. The hostname or IP address of the vSphere vCenter or ESXi server. Using a single image to manage all hosts in a cluster ensures cluster-wide host image homogeneity. You can use various methods and tools to deploy ESXi hosts and maintain their software lifecycle. The GuestAliasManager supports single sign-on for virtual machine access to perform guest operations. For example, you can upgrade hosts by using VMware vSphere ® ESXi™ Image Builder CLI, esxcli, vSphere Auto Deploy. The different deployment and upgrade choices involve different workflows and require you to use different ESXi image formats. When you use vSphere Lifecycle Manager images, you follow one workflow and use the same ESXi image format for all software lifecycle-related operations: install, upgrade, update, and patching, which significantly simplifies the lifecycle management process. Understanding vSphere Lifecycle Manager ImagesĪ vSphere Lifecycle Manager image represents a desired software specification to be applied to all hosts in a cluster. VSphere Lifecycle Manager image can consist of the following four elements: When you set up a vSphere Lifecycle Manager image, you can define the full software stack that you want to run on the hosts in a cluster: the ESXi version, additional VMware software, vendor and third-party software, for example firmware and drivers. The base image contains an image of VMware ESXi Server and additional components, such as drivers and adapters that are necessary to boot a server. The base image is the only mandatory element in a vSphere Lifecycle Manager image. Last part of setup comes down to configuring some environmental variables. Some of the examples include ESXi host connection and disconnection, VM creation, and VM power actions. The vendor add-on is a collection of software components that OEMs create and distribute. The vSphere Automation REST Samples is a couple groups of requests which can be combined to perform a normal task. The vendor add-on can contain drivers, patches, and solutions. The firmware and drivers add-on is a special type of vendor add-on designed to assist in the firmware update process. The firmware and drivers add-on contains firmware for a specific server type and corresponding drivers. To add a firmware and drivers add-on to your image, you must install the hardware support manager plug-in provided by the hardware vendor for the hosts in the respective cluster. The component is the smallest discrete unit in an image. Depending on the type of content, baselines are patch baselines, extension baselines, and upgrade baselines.The independent components that you add to an image contain third-party software, for example drivers or adapters.īaselines can be classified according to different criteria. Depending on how the update content is selected, baselines are fixed and dynamic.Patch and extension baselines contain bulletins of the respective kind.
