Where to specify the azure storage container details in SPFx?

 Ans:-

If you want to host your SPFx apps in Azure CDN storage container, SPFx provides options for that as well in the config/deploy-azure-storage.json file. Use the gulp task gulp deploy-azure-storage

{  

  "$schema": "https://dev.office.com/json-schemas/spfx-build/deploy-azure-storage.schema.json",  

  "workingDir": "./temp/deploy/",  

  "account": "<!-- STORAGE ACCOUNT NAME -->",  

  "container": "spfx-1",  

  "accessKey": "<!-- ACCESS KEY -->"  

} 

• workingDir - all files from this location will be moved to Azure
• account - Azure storage account name
• container - storage container name of this app
• accessKey - Key to access the storage account
