App Service deployment slots and traffic validation

Problem

You need a quick, safe way to work with app service without guessing the current state.

Solution

Start with the smallest verification command, confirm scope, and document what you saw before changing anything.

Command Or Example

az webapp deployment slot list --name <APP_NAME> --resource-group <RESOURCE_GROUP>

Explanation

This pattern keeps the first change reversible and makes troubleshooting easier for app service.

When To Use

Use it before production changes, troubleshooting sessions, or when you need a quick sanity check.

Common Mistake

Skipping scope validation and assuming the portal or CLI is pointing at the right resource.
