Deej, Adding to Lex Li response. Could you please provide details about you app framework?
Based on my understanding of your issue description, you are experiencing an issue where your Azure App Service is serving old files despite deploying new changes.
Set WEBSITE_RUN_FROM_PACKAGE
environmental variable --the app setting is set, this command doesn't extract the package content to the D:\home\site\wwwroot directory of your app. Instead, it uploads the ZIP file as-is to D:\home\data\SitePackages, and creates a packagename.txt in the same directory, that contains the name of the ZIP package to load at runtime. See this doc for more info: deploy-run-package#run-the-package
Additionally, just to isolate, if your app settings include caching options, consider disabling them
-
WEBSITE_DYNAMIC_CACHE = 0
-
WEBSITE_LOCAL_CACHE_OPTION = Never
To fetch more info, you may check the deployment logs in Azure DevOps and App Service logs to: #enable-application-logging-linuxcontainer
Kindly let us know, we will follow-up with you further.
