| artifact |  A file of any kind produced during a container build process or associated with the operation of a container. For example, a Helm chart is an artifact that might be stored along with a container. |  
  | CNCF |  As part of the Linux Foundation, the Cloud Native Computing Foundation provides support, oversight, and direction for open-source, cloud native projects. |  
  | cosign |  cosign is a tool that performs container signing, verification, and storage in an OCI registry. |  
  | cosigned |  cosigned is an image admission controller that validates container images before deploying them. |  
  | cri-o |  cri-o is an implementation of the Kubernetes Container Runtime Interface (CRI) to enable using OCI compatible runtimes. It is a lightweight alternative to using Docker as the runtime for Kubernetes. |  
  | deduplication |  A storage space saving feature wherein only a single copy of specific content is maintained on disk while many different image manifests may hold references to that same content. |  
  | digest |  A hashed checksum, such as SHA-256, for verifying the integrity of the downloaded image. |  
  | Distribution Specification |  The OCI Distribution Specification project defines an API protocol to facilitate and standardize the distribution of content. |  
  | extensions |  Additional registry features (APIs) that are not a part of the Distribution Specification can be added as Extensions. |  
  | helm chart |  A helm chart is a package of files that orchestrate the deployment of Kubernetes resources into a Kubernetes cluster. |  
  | manifest |  An image manifest provides a configuration and set of layers for a single container image for a specific architecture and operating system. |  
  | node exporter |  A software component that collects hardware and operating system level metrics exposed by the kernel. |  
  | OCI |  The Open Container Initiative (OCI) is an open governance structure for the express purpose of creating open industry standards around container formats and runtimes. |  
  | ORAS |  OCI Registry as Storage (ORAS) is a tool for distributing OCI artifacts across OCI registries. |  
  | prometheus |  Prometheus is a node exporter that exposes a wide variety of hardware- and kernel-related metrics. |  
  | referrer |  An image containing a non-nil subject field with a descriptor to the referred image. |  
  | registry |  A service that stores and distributes container images and artifacts. |  
  | repository |  A collection of images with the same name, differentiated by tags. |  
  | skopeo |  skopeo is a command line utility that performs various operations on container images and image repositories. |  
  | stacker |  stacker is a standalone tool for building OCI images via a declarative yaml format. The output of the build process is a container image in an OCI layout. |  
  | tag |  A label applied to an image that distinguishes the image from other images in the same repository. A common example is a version tag. |  
  | zb |  A benchmarking tool, available as a zot companion binary, for benchmarking a zot registry or any other container image registry that conforms to the OCI Distribution Specification. |  
  | zli |  A zot companion binary that implements a set of command line commands for interacting with the zot registry server. |  
  | zui |  A zot companion binary that implements a graphical user interface (GUI) for interacting with the zot registry server. |  
  | zxp |  A node exporter, available as a zot companion binary, that can be deployed with a minimal zot image in order to scrape metrics from the zot server. |
