Overview: Azure CLI terminology and support levels

This article explains Azure CLI terminologies. There are syntax components, reference types, and statuses.

Azure CLI syntax components

The Azure CLI syntax is a combination of groups, references, commands, and parameters. Often the full reference command is referred to as command.

Azure Service Reference group Reference subgroup(s) Command Full reference command Parameter Examples
Azure CLI az config az config --local, --output -o
Azure Network az network application-gateway create az network application-gateway create --name, --resource-group, --capacity
Azure DevOps az pipelines agent list az pipelines agent list --pool-id, --agent-name, --demands

A reference subgroup can have multiple levels such as az network application-gateway private-link ip-config add

Reference Group Subgroup 1 Subgroup 2 Subgroup 3 Command
network application-gateway private-link ip-config add

See Reference list A to Z for a complete list of reference commands.

What is reference type?

Azure CLI commands are either part of the core Azure CLI service, or they're an extension. Extensions are optional add-ons. The reference type determines the release schedule, status and installation method as described here:

Term Core Extension
References Are part of the primary Azure CLI service Are optional reference commands that must be installed
Install Jointly with the MSI installer Individually with az extension add
Released On a schedule As new features or updates become available
Status Can be GA (Generally Available), preview or deprecated Also can be GA, preview or deprecated

To get a list of command groups, run az. For a list of extensions, use az extension list-available --output table commands.

# Get list of all command groups
az

# Get list of extensions
az extension list-available --output table

Core

Azure CLI references that have been published as a permanent part of the CLI are called core references. All core references install with the Azure CLI and you can't choose a subset of references. If you run the CLI through Azure Cloud Shell, core references are always up to date.

Extension

Extensions aren't shipped as part of the CLI but run as CLI commands. Some extensions are a permanent part of the Azure CLI, but often, an extension gives you access to preview and experimental commands. A single reference group, such as az iot hub, can have both core and extension commands. Here are two examples:

Full reference command Is Core Is Extension
az iot hub list yes
az iot hub job list yes

You're prompted to install an extension upon first use. You can also install an extension by running the az extension add command.

You can learn more about extension references including installation and updating in Use extensions with the Azure CLI. See Available extensions for the Azure CLI for a complete list of extension reference commands.

What is reference status?

Regardless of reference type, Azure CLI references fall into three status categories: GA (Generally Available), public preview or deprecated. It's the reference command status (not type) that determines stability.

GA Public preview Deprecated
Stability Permanent Can change in response to customer feedback. Is subject to the terms of Microsoft Azure Previews. Will be removed.

Note

Warnings indicating public preview or deprecated are part of the Azure CLI command output and should be expected.

Most commands and parameters for a single reference have a single status, but not always. A GA reference that is being built out to offer more commands can have both GA and preview reference commands. As new parameters are added to increase functionality, a single command can also have parameters that fall under different status categories. Here are example references that have different statuses:

Full reference command Parameters Type GA Public preview Deprecated
az network dns zone list All Core yes
az network dns zone create --name, --resource-group, --if-none-match, --parent-name Core yes
--existingParameter5 Core yes
--newParameter6 Core yes
az network vhub list All Extension yes
az network vhub create --address-prefix, --name, --resource-group, -vwan, --location, --sku Extension yes
--exsitingParameter7 Extension yes
--newParameter8 Extension yes
az network firewall create All Extension yes

The above table is only an example and isn't representative of the current reference statuses for az network.
