Question

This is my first time using Docker, and I don't understand why this issue is occurring. I have exhausted all of my options and need some help, please!

Is it true that if I use Docker, it can become a public IP and anyone with the link can access it?

@86 , Apologies for the delay from over the weekend and any inconvenience with this issue.

From your issue description and screenshot, I understand you have deployed an App Service WebApp

[http://9034test.azurewebsites.net/] ( App Service Linux, Free SKU) and while accessing the WebApp, you’re receiving ‘Application Error’.

--Docker is not exposed to the internet by default. However, you can expose your containers to the internet by specifying one or more ports to open, a DNS name label, or both.

• Quickstart: Deploy a container instance in Azure using the Azure CLI

--In regards to the site that you have hosted on Azure App Service -[http://9034test.azurewebsites.net/]  --- Azure App Service Web Apps can be accessed publicly over the internet by default. However, you can restrict access to your web app by configuring access restrictions. Access restrictions allow you to define rules that allow or deny access to your web app based on IP address or a virtual network.

Checkout these docs for more info:

Set up Azure App Service access restrictions

--For fixing Application Error - It could be an issue in application startup that's preventing it from loading all the way. 

1. 1. 1. Review the logs to fetch more details about the error -  Enable application logging (Linux/Container) to look for any issues.
2. You may leverage App Service diagnostics from Azure Portal> Navigate to your App Service app in the Azure Portal.

• In the left navigation, click on Diagnose and solve problems – Checkout the tile for “Diagnostic Tools” > “Availability and Performance” & "Best Practices" and review to fetch additional information to isolate further.

Kindly let us know how it goes, I'll follow-up with you further.
