  1. Add comment field to IP Restrictions list

    Would be helpful to be able to associate a comment or description with each IP address/range similar to the firewall UX in Azure SQL DB.

    • [Linux] Add some container orchestration features to App Service to provide high density

      Azure App Service is the Easy Button for app deployment and hosting, whereas Service Fabric and containers add significant complexity. However, Service Fabric and containers scale much more efficiently. It would be amazing if you could add some basic container orchestration features in a way that would make App Service the Easy Button for container-based deployments, including high density. I realize this is a challenging request, but like I said, it would be amazing!

      Thanks!

      • App Service - Allow Named Pipe Activation to be enabled

        We would like to use named pipes to communicate between services on the same app service, but this doesn't seem to be possible since named pipe activation isn't enabled in .Net on the app service.

              • Document the clock syncronization between App Service

                I couldn't find anywhere about the clock synchronization between different instances of an App Service and also between App Service and other Azure services (e.g. Azure Storage, Service Bus etc.)

                What we need to know is if there is any grantee that if we take DateTime.UtcNow on two instances of App Service (website), to which degree they will be comparable.

                Also to which degree the clocks of App Service (website) match with other Azure infrastructure. As currently I think there is miss-match in seconds. Take a look at following example of what we are currently seeing in our system on…

                • Update Web App ModSecurity module to 2.9.2

                  The current version of the ModSecurity module that is integrated in the IIS of the Web App Services is 2.8.0.
                  This version of ModSecurity has issues with the IP + Port formatting of the AlwaysOnline service. Please update it to 2.9.2.

                  • App services should show the max supported version of ASP.NET core

                    If you deploy an app with a version of .NET Core that isn't deployed on Azure yet, you get horrible to debug errors that you have to enable stdout logging on to get to the bottom of.

                    (Ultimatly editing csproj with PublishWithAspNetCoreTargetManifest set to false)

                    Confusing and time consuming. It would be great if Azure showed you some where on the app, a max supported version of .NET core and some kind of publishing warning if you try to push something higher.

                            At the moment an Azure App service has the ability to white list IP addresses through the Networking > IP Restriction blade. It would be useful if this could be configured through PowerShell.

                            • Document healthcheck URL requirement for custom containers

                              With Web App for Containers, it seems Azure uses a special URL "/robots933456.txt" to check when the container has started, and expects a valid HTTP response (404 is fine). This requirement for custom containers should be mentioned in the documentation! (and preferably, it should be configurable)

                              • Azure Web App auth customize WWW-Authenticate challenge

                                Support authorization_uri in Azure AD Pre-Auth for Web Apps

                                https://stackoverflow.com/questions/46908858/azure-web-app-auth-customize-www-authenticate-challenge

                                According to some docs (https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-code#use-the-access-token-to-access-the-resource), the WWW-authenticate header should return authorization_uri like this:

                                HTTP/1.1 401 Unauthorized
                                WWW-Authenticate: Bearer authorization_uri="https://login.microsoftonline.com/contoso.com/oauth2/authorize", error="invalid_token", error_description="The access token is missing.",

                                But since we use the pre-authentication features of Azure Web Apps, we can't control that directly from code.

                                • WebApp custom DNS with private DNS Name

                                  Custom DNS HostName for a WebApp is working exactly in the same way in both Azure and Azure Stack, with both ownership and record check against a public Internet DNS server. That's pretty cool for public facing web applications, but represents a security issue for :
                                  1)Intranet applications.(hosted on Azure or AzureStack)
                                  - Custom Domain Names makes sence not only for Internet but Intranet too.
                                  - We don't want to expose intranet application names publicly to the wild...
                                  2)Multi-tenant AzureStack
                                  - Each customer would like to have it's own custom domain for its applications, and not use the *.appservice.local.azurestack.external or…

                                  • Aggregated logs for Linux App Service instances

                                    To access logs for my Linux App Service instance i have to go to myapp.scm.azurewebsites.net/api/logs/docker and it lists all the instances i have running with a link to the log file for each node. This is cumbersome when trying to debug an issue. Could we have an option under diagnostic logs to target a storage Table and have these aggregated as one source

                                    • Display slots should list their full name in the resource lists.

                                      When you are viewing resources in the "All Resources" blade or in the "Resource Group" blade all slots are just listed using only their slot name, if you have many different web apps that all use slots you will see the same name repeated several times (see "Example Resource Group.PNG").

                                      I suggest you display the name from the resources blade the same way you display it in the delete menu if you are deleting the base web app "BaseName-SlotName" (See "delete example.PNG")

                                      • DNS resolution is not working in Azure Web App for Containers (linux)

                                        DNS resolution is not working in Web App for Containers (linux) when using custom docker image. The DHCP generated resolv.conf is broken. After using SSH to log in to the container trying nslookup google.com also fails with DNS resolution error.

                                        See my sample project for more details:

                                        https://github.com/henkosch/azure-webapp-dnstest

                                        The problem is also mentioned in the comments section on this page:

                                        https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-faq

                                        Does anyone have an idea how to fix this?

                                        • REST API shouldn't return 0 when it doesn't have the actual data

                                          Calling the REST API to get CPU or memory usage of an app service plan, if you ask for it in the last minute it can return 0 to you, when a few minutes later it will return the actual value for the same time, it seems it takes a while for the real data to be available to the API, however I think it's wrong to return incorrect data, it should not return a value until it has the real value.
