Step 5: Install and configure the host (Docker)

You can install Docker on any server that meets the requirements for Lenovo XClarity Administrator

Before you begin

You can use Docker Datacenter to set up a high-availability environment for XClarity Administrator containers running in Docker Engine. For more information about Docker Datacenter high availability, see High Availability Architecture and Apps with Docker Datacenter webpage.

Ensure that the host meets the prerequisites that are defined in Supported host systems.

Ensure that the host system is in the same network as the devices that you want to manage.

Important: You can setup XClarity Administrator on any system that meets the requirements for XClarity Administrator, including a managed server. If you use a managed server for the XClarity Administrator host:
  • You must implement either a virtually separate data and management network topology or a single data and management network topology.
  • You cannot use XClarity Administrator to apply firmware updates to that managed server. Even when only some of the firmware is applied with immediate activation, XClarity Administrator forces the target server to restart, which would restart XClarity Administrator as well. When applied with deferred activation, only some firmware is applied when the XClarity Administrator host is restarted.
  • If you use a server in a Flex System chassis, ensure that the server is set to automatically power on. You can set this option from the CMM web interface by clicking Chassis Management > Compute Nodes, then selecting the server, and selecting Auto Power for the Auto Power On Mode.

Procedure

Install and configure Docker on the host using instructions that are provided with your Docker distribution.
