az webapp is a core command group in the Azure Command-Line Interface (CLI) for creating, deploying, configuring, and managing web applications on Azure App Service. Azure Web Apps provide a PaaS platform supporting languages like .NET, Java, Node.js, PHP, Python, and Ruby, with built-in CI/CD, auto-scaling, and high availability.

Key capabilities include rapid setup and deployment with az webapp up (detects settings and pushes code), detailed creation via az webapp create, runtime configuration with az webapp config (appsettings, connection strings, slots), deployment slots for zero-downtime updates, log streaming (az webapp log tail), and hybrid connections. It supports containerized apps via Docker and custom handlers.

Designed for automation, it excels in scripts, GitHub Actions, and pipelines, with JSON output for parsing. Requires Azure CLI v2.0+ and az login authentication. Cross-platform on Linux, macOS, Windows.

Requires Azure CLI 2.0+, az login authentication, and appropriate RBAC permissions. Many subcommands need --resource-group and --name. Preview features marked as such may change.

up: Quick create/deploy.
create: Create web app.
deploy: Deploy zip/Git/Docker.
config: Manage settings/slots.
log tail: Stream logs.
list/show: List/view apps.

Install via curl -sL https://aka.ms/InstallAzureCLIDeb | bash. Authenticate with az login. Set default location like --location westus.

Introduced in Azure CLI 2.0 (2017-2018) alongside App Service evolution. az webapp up added ~2019 for simplified deployments. Regularly updated for Linux containers, managed identities, and multi-region support.
