Deploying Project from VS to App service: Container ***** didn't respond to HTTP pings on port:-CodePudding

I'm trying to deploy Django project to Azure App Service through Visual Studio. Once deployed and if I open the app URL an error is displayed ":( Application Error". Same error occurs if deployed from the GitHub Actions CI/CD through service principles.

Logs displaying this error "Container **** didn't respond to HTTP pings on port: 8000, failing site start"

Unable to find any solution for this.

Any help would be appreciated.

CodePudding user response：

By default, App Service assumes your custom container is listening on port 80, however, your application was listening to requests on port 8000, which led to the error.

If your container listens to a different port, set the WEBSITES_PORT app setting in your App Service app.

That is an WEBSITES_PORT as one of your app settings with the port your app is listening.

You can set it in Azure CLI:

az webapp config appsettings set --resource-group <group-name> --name <app-name> --settings WEBSITES_PORT=8000

(OR)

In Azure PowerShell:

Set-AzWebApp -ResourceGroupName <group-name> -Name <app-name> -AppSettings @{"WEBSITES_PORT"="8000"}

Note: App Service currently allows your container to expose only one port for HTTP requests.
