  1. [Linux] Give Linux web apps same deployment options as Windows based apps

    Linux based web apps have 3 deployment options (GitHub, BitBucket, Local Git repo) whereas Windows based apps have 7 deployment options (including the "External Repository" which is what I was looking for).

    This request is to bring the options for Linux based apps up to speed, and perhaps until then, provide documentation and/or UI verbiage as to why there are differences. I spent an hour or two trying to hook up GitLab as a deployment option (including trying to use the Azure CLI) in vein.

    BTW the CLI gives a cryptic error message when trying to add an external repository.…

    • Linux / Docker for ASE

      We are using ASE and would like to deploy Web Apps using docker containers with linux to be able to run NodeJS applications on Azure.

      For now, with our configuration, there is a limitation => we can only deploy NodeJS applications on Windows with IIS, not docker/linux.

      We need linux too ! <3

      • Linux Static Site on Nginx

        One of the most common web techniques today is static generated web sites. Ideally, there would be an option along with Node, Php etc for Static HTML. This would allow configuration for just running Nginx web servers to host static sites.

        • Provide an interface for dictating logic to the load balancer, or allow us to nuke instances

          The load balancer for an App Plan is extremely simple minded in that it will always distribute load evenly.

          This doesn't work in a production environment with real users.

          e.g. if a webjob running on one machine picks up an intensive task from a queue, consuming all of the machine's resources, the load balancer will still forward users/requests to the affected machine.

          Please provide some sort of control over the load balancer. Even just a basic interface to provide basic rules.

          If you won't provide that, then at least instead allow us to nuke instances ourselves and provide us with…

            For heterogeneous workloads, the recommendation is to split the apps apart into separate app service plans. For example, webjobs isolated to in an app service plan separate and apart from the app service plan(s) running web or API applications.

            We will keep this item open marked as “under review” because there are plans to onboard the per-worker metrics to the Azure Monitor feature, at which point programmatic scaling decision can be made from those metrics.

            Currently worker metrics can be viewed from the UX by clicking into “Diagnose and Solve Problems” link for an app service plan. There will be a link in the UX blade that opens titled “Metrics per instance”. Drilling into that link will pull up another UX blade showing CPU usage (amongst other statistics) broken out by individual worker VMs.

          • Metric and alert for Web App file system used quota

            We would like to setup an automatic alert that fires when the file storage of an app plan is reaching its limits.

            Ideally it will be great to have a metric that tells the % of storage (quota) consumed so we can set an alert on top of that metric.

              This is a great idea and we would like to implement it though there are a few dependencies we need to meet first. We are leaving this on the roadmap for now to see if it gains more customer support which will help with prioritization.

              Thanks,
              Oded

            • A method to allow folks to access the FTP transfer logs when ftp is used to deploy code changes to their azure web apps.

              Allow site admins to access the ftp transfer logs when ftp is the selected method used to make web site deployment updates. We use ftp to allow site updates, and we've had an incident where having access to those logs would be very helpful.

              • The overwritten data in Connection stringsis not reflected in Backup Configuration.

                When we choose the Backup Database from Backup configure after The connection strings is overwritten.There is a bug.That doesn't seen to have problem.
                Using the DevTools(F12),make sure sending datas. The overwritten data in Connection strings of Application setting is not reflected .
                we have to delete the data once and add new data to avoid this bug and update new data in application setting.

                • [Azure web app LINUX] VSTS deploy to slot

                  Currently I am using VSTS for my CI/CD to azure web app linux
                  However, unfortunately, there's still a pretty significant downtime for every deployment.

                  I tried to create a staging slot to minimize the downtime, and swap to production. however, VSTS doesn't allow me to deploy to my staging slot.

                  I created a github issues too here https://github.com/Microsoft/vsts-tasks/issues/4460

                  If I can't deploy to my slot, what's the point of having slot in the first place? Please prioritize this as I think this is a pretty important feature

                  • Way to monitor Web App connections regardless of state

                    I had an issue where my web app was unable to open new connections because too many were open. The metrics-per-instance reports for monitoring connections only show open and close-wait state connections. For whatever reason the connections impacting my app were in another state and hence were not shown.

                    I believe I have resolved my issue, but I cannot check on the health of the app without asking an Azure support technician to assist.

                    It can also be misleading when troubleshooting to see 80 connections in the report, when there are actually 3500 in use.

                    Thanks!

                    • Associating Hybrid Connections to Azure App Services cannot be automated

                      There is no way to associate a Hybrid Connection to an Azure App Service via ARM Template or PowerShell.

                      This is a significant gap since we cannot automate this at all when that is the driving factor for DevOps and PaaS services.

                          Hi,
                          thanks for the feedback. This is not currently possible as client cert auth on App Service is in require mode and as such cannot be delegated to folder level.

                          We will review this item and your feedback, we may look to implement this capability based on customer prioritization.

                          Thanks

                        • Make Application Gateway WAF services available for non-ASE App Service plans

                          The Application Gateway and specifically WAF are useful even for simpler apps because of the OWASP and general security protections afforded.

                          App Service Environments are extremely costly compared to a loaded Standard S1 or Premium P1 App Service plan and the Application Gateway/WAF cannot be used without the ASE.

                          While there are WAF solutions provided by 3rd parties it would be great if the Azure solution used for ASE's was also available for standard App Service plans.

                          Thanks

                            We need a consolidated way to see near-realtime CPU and Memory consumption for each Web App per App Service Plan. This way we can quickly identify which apps are consuming the most resources (specifically CPU and Memory) in that App Service Plan.

                            1. We run many web apps in each App Service Plan. We don't want to pay for a new App Service Plan until all memory (or CPU) is consumed on what we currently have. I could rebalance the sites (move some to another plan) if I could easily see…

                            • Provide more secure TLS ciphers

                              Currently Chrome flags the CBC ciphers as obsolete. CBC ciphers are at the top of the cipher preference list of Azure Web Apps as you can see there: https://www.ssllabs.com/ssltest/analyze.html?d=test.azurewebsites.net
                              More info: https://www.chromium.org/Home/chromium-security/education/tls#TOC-Cipher-Suites


                              So please provide some more secure ciphers from the ECDHE cipher suite like TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256.

                              • in ASE disable TLS 1.1

                                Allow for the disablement of TLS 1.1 protocols from ASE in a similar method as TLS 1.0. This would help secure systems further for ISVs building new API Apps and help with additional security concerns and compliance for PCI and others.

                                Allowing for the same method but adding an additional JSON in cluster settings to actually trigger the TLS 1.1 disablement would be good.

                                "clusterSettings": [
                                {
                                "name": "DisableTls1.0",
                                "value": "1"
                                },

                                • FTP accounts tied to subscription, not user. Not enough auditing

                                  In the current model, FTP credentials are tied to a user's azure login. Thus, we have no visibility into credentials that are set, as we cannot see other people's FTP credentials they've set. Furthermore, when an FTP account is created or deleted, nothing is logged. This makes it difficult to audit who has access. With the logins being tied to the user, when the user leaves, there is no way for us to reclaim that username unless they delete their ftp credentials first. This doesn't always work, as a user may depart abruptly or not on good terms. Although the…

                                  • Hybrid Connection Manager Support for Linux

                                    We are an ISV leveraging Azure PaaS to provide an iPaaS service to customers. We have a requirement to connect to on premise servers to access line-of-business apps. Currently, we leverage Azure’s Hybrid Connection Manager --- but are limited to Windows servers only. Our customers have both Windows, Linux and mixed environments. This considerably limits our market.

                                    Can we expect Linux support? If so, when? Any suggested work arounds?

                                    Thank you for your consideration.

                                      • Provide option to make Diagnostic Logging settings sticky to a slot

                                        We make generous use of sticky slot settings. They enable us to swap code without swapping configuration.

                                        Unfortunately for our design, diagnostic logging settings cannot be marked as sticky. Before a swap, our production slot might be logging to a production storage account, and our staging slot might be logging to a staging storage account. After the swap, production is logging to stage, and stage is logging to production. This results in muddy log files where one cannot be certain which slot was responsible for which log entries.

                                        Please provide an option to make diagnostic logging settings sticky to a…

                                        • [Linux] Allow to access certicate store within linux app services

                                          It is currently not possible to use certificates in Linux App Services as described in this blog post:

                                          https://azure.microsoft.com/en-us/blog/using-certificates-in-azure-websites-applications/

                                          Please add access to the azure certificate store within a linux container.
