1. Introduction
Edge Virtualization Engine (EVE-OS) is a secure operating system that supports running Virtual Machines or Containers on computing devices deployed in the field. These devices can be IoT gateways, Industrial PCs, or general-purpose ruggedized computers; collectively, these are referred to as Edge Nodes. EVE-OS is an open-source project under Linux Foundation Edge.
An EVE-OS Image is binary data released by Linux Foundation Edge. ZEDEDA manages these EVE-OS images and makes them available to all enterprises on its Cloud Controller platform.
At any point, an enterprise may have multiple versions of EVE-OS images. An administrator user of the enterprise can mark one of the EVE-OS images as the "latest" image for the enterprise. Users can then upgrade the Edge Node(s) with the 'latest' EVE-OS image. Click here for more details.

2. Operations using ZEDEDA CLI
To log in to the ZEDEDA platform through ZEDEDA CLI, see here.
2.1. Read (Show)
You can use the following command to see the created EVE and App Images details:
zcli> zcli image show [[[<name> | --uuid=<uuid> | --latest=[AMD64|ARM64]] [--detail]] | [--type=[Eve|Application|EvePrivate] --arch=[AMD64|ARM64] --status=<status> --datastore-name=<datastore> --summary --name-pattern=<name-pattern>]]
For example, the show command for an image displays the following output:
zcli> zcli image show
