  1. Allow IP Restrictions to be a Slot Setting

    In the same way as we have with App Settings it should be possible to make the IP Restrictions a slot setting (sticky) so that they don't migrate when you swap slots. This could be per IP even....

    • Support Availability Zones for App Service Environment

      With Azure SQL and Storage having zone redundant capabilities and Application Gateway in preview, App Service Environment is soon to be the only thing keeping us from fully PaaS, zone redundant web applications.

        • Automatically rebind SSL Certs that have Auto-Renew

          Right now there is a way to purchase and Auto-Renew SSL-Certs for Web Apps. Unfortunately, the Auto-Renew does _NOT_ also bind the new cert to the WebApps where the cert it is replacing is currently bound to.

          This makes Auto-Renew more or less useless, as one still has to manually bind the new cert once it becomes available.

          A cert with Auto-Renew should automatically bind to all WebApps where the cert it replaces is used.

            Hi Thomas,

            Some feedback from our team:

            We do not update the SSL binding on rare cases, and we do have the code working just that it happens on a different task. This is definitely a bug we will be fixing as soon as we can. Most likely will be dealt with in June.

            Thanks,

          • App Service Environments Architecture and Cost

            I love using App Service Environments; however, the cost is shocking. We like that our App service can communicate over our express route to our data center. I gained some new understandings with how these services work on the back-end and it seems confusing. I have an understanding that normal App Service Plans operate such that a fault tolerant pair is available in a different part of the data center and in the event of a failure, your code is moved to the other pair. This is great and I love that. With ASE's the architecture changes and the use…

            • Provide acceptable scale out time for instances in ASE Isolated instance types

              Scaling is a core feature of App Services. We used ASE for the additional features however it means we are stuck with 40 mins scale out time to add an instance. Per support this is by design, however this is not documented anywhere in public domain.
              Scaling is supposed to help us get customers on to Azure, if it takes 40 mins to add an instance, it will not meet the business needs, we abandoned ASE only due to this issue. Kindly document current scale out time in public documentation so that user know this before hand.
              Ultimate goal should…

                Thanks for the feedback!

                You’re right that ASE scaling operations take longer than the common plans on multi-tenant App Service. We are looking at ways to decrease the time so it will on par with multi-tenant but this means a new infrastructure is needed with managing a pool or pre-assigned VMs to the ASEs.

                This is documented here, though without a time frame mentioned as it depends on a numbers of factors: https://docs.microsoft.com/en-us/azure/app-service/environment/using-an-ase#how-scale-works.

                We will update when there is more information here.

                Thanks,

              • Azure App Service Environment ILB - Support for Internal Certificate Authorities

                Currently the documentation for Azure App Service Environment with ILB claims it supports internal certificate authorities.

                Per - https://docs.microsoft.com/en-us/azure/app-service/environment/create-ilb-ase#post-ilb-ase-creation-validation

                As part of the documentation it is recommended that a user bundles their server auth certificate with the full certificate chain - thus producing a PFX file or base64 encoding it and uploading through powershell.

                However when testing with OpenSSL or on an iOS device, the first request never sees the full certificate chain and fails with "invalid server certificate". It is on a subsequent request the full chain is delivered - leaving users to hit refresh once in their browser…

                  Azure PowerShell and Azure CLI commands to support the management of an App Service Environments (at least v2). Hopefully this could include the ability to get management IP information, do scaling, and if it is an ILB ASE update the ILB Certificate.

                    • Make Web App Timeout of 230 seconds configurable

                      Currently there is a 230 second hard timeout in web apps. We have certain reporting functions that run for a large dataset and they timeout. I've seen plenty of workarounds for this, but they all involve a substantial rearchitecting of the app. Since you can put a web app in its own app service plan, this 230 second timeout seems highly arbitrary and against the general flexibility that should be left to the developer and administrator.

                      Please make this timeout a configurable value and leave it defaulted to 230 seconds.

                      • Enable users to isolate an App Service Plan instance in order to perform offline debug

                        It’s difficult to balance root causing live fails with keeping a production application running. This feature request attempts to address this by asking for a way to isolate an ASP instance in a running application.

                        By isolating a misbehaving instance you can prevent it from affecting the behavior of the application overall. It can be studied for root cause without app devs or support being pressured to do this live on a production app. When debug is complete it could be terminated.

                          • Enable application logging in ILB ASE

                            Currently there is no way to access our applications trace logs in an ILB ASE environment. I understand the Log Stream button is greyed out in the portal, but even using Kudu, FTP, blob, or streaming in VS, none of these are working in ILB ASE, and support tells us this is a known issue. This is a huge downside for us because we depend on our customized application log messages for troubleshooting.

                              A common (if not best) practice is to compose applications of multiple containers for the sake of separation of concerns. However, Azure doesn't support authentication with Azure Active Directory for multi-container apps. Until this is in place, we can't deploy our applications to Azure in a clean way.

                                • Support Healthcheck for Docker on App Service

                                  We just learned the hard way that HEALTHCHECK declarations in Docker containers stop working if the container is running in App Service, because App Service for some reason seems to alter the behavior of our containers to do some "internal" healtchecks.

                                  I believe that this goes very much against the spirit of containerized applications. I have to trust that my container behaves the same no matter who runs it.

But after that there was no update on this issue and it looks like that thread was not updated for a while.

                                      Now that Notary/Content Trust in available in ACR, it would be useful if it could also be enabled in the ASE so it could only pull signed images.

                                      I can't see a way to currently do this - is it possible?

                                      • Generate internally-issued certificates

                                        There should be a way to generate internally-issued certificates for ASE so ASE's have no legacy-dependency. Currently one has to have CA running in a VM to generate that for the domain.

                                        • Autoscale settings for service plan tier (scale up) in addition to (scale out)

                                          I'd like to be able to configure auto-scale on the pricing tiers in addition to scaling out. For example, during the overnight ours, I don't need a app service plan of p2v2, but during the day, I do normally need 2 sometimes 3 p2v2 instances. I'd like to be able to say during the hours of X - Y, make the app service plan p1v2, and A - B be p2v2. I don't know that a more complex situation like CPU usage is necessary, but maybe others would want it, but in general it would be nice to automate that…
