I am using the latest azure cli. When I first use this command az containerapp

The result is below. It makes me confused and the containerapp extension is not installed automatically.

$ az containerapp
'containerapp' is misspelled or not recognized by the system.
Did you mean 'container' ?

But when I type az containerapp -h. I get prompt to install containerapp extension.

$ az containerapp -h
The command requires the extension containerapp. Do you want to install it now? The command will continue to run after the extension is installed. (Y/n): Y
Run 'az config set extension.use_dynamic_install=yes_without_prompt' to allow installing extensions without prompt.
The installed extension 'containerapp' is in preview.

Describe the bug

To Reproduce

Expected behavior

From doc https://learn.microsoft.com/en-us/cli/azure/containerapp?view=azure-cli-latest. The doc said when user type "az containerapp" it will automatically install containerapp extension. But actually, it doesn't.

I expect the azure-cli could support automatically install containerapp extension as doc said.

Your CLI is up-to-date.

The extension will automatically install the first time you run an az containerapp command.

az containerapp is not a command, it's command prefix.
If you type a complete command, for example az containerapp show, cli will ask you whether to install it.

This is by design #17698. One command prefix might be shared by different extension, if the command is not complete, we don't know which extension should be installed.

update:
This behavior also fixes infinite loop in #17696 (comment)

[ruowan]

Actually, az cli know all the supported extensions. I could add extension by az extension add -n containerapp. So you could implement same logic for az <extension-name> command. And why it's by design?

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @macolso.
