I've set some application settings in the azure function app but I'm getting null when I try to read them
System.ConfigurationManager.AppSettings[name]
System.Environment.GetEnvironmentVariable(variableKey, System.EnvironmentVariableTarget.Process)
Both of them gave me null. I can get the value fine running on local where my settings are in local.settings.json
(pulling the answers from the comments to aid in future searches)
When dealing with Appsettings, try restarting the app. (although normally the site would restart automatically when you change an appsetting)
You can use Kudu to verify the appsettings are indeed properly set on the site. (https://{app}.scm.azurewebsites.net) and click on Environment tab). They'll also show up as environment variables.

i'm trying to setup my project in azure. For this i created an app service and under settings/configuration i added some "Application Settings", which in my understanding are environment variables. However i deployed my docker image which azure pipelines and everything is okay, but when i connect through ssh to the instance and call 'env' i don't see any of my environment variables.
From the documentation i should be able to call them inside php as every other env variable (getenv..). Maybe i miss something or my understanding of this app settings are incorrect.
Would be great if somebody has an idea about what is wrong, if you need more informations hit me up.
Partly, you did not make mistake on the way of accessing setting/configuration which set as environment variable. The getenv() is correct.
when i connect through ssh to the instance and call 'env' i don't see
any of my environment variables
I think this issue may caused by your script. When you access these setting keys, do not lost Prefixed. This is the important way to access and get these environment variable. For example, if you want to access app settings, the name of the corresponding environment variable should prepended with APPSETTING_.
At this time, the sample script for PHP script should be:
<?php
$appsetting = getenv('APPSETTING_{Key}'); echo $appsetting;
?>
Note: The {key} is the key name you configured in Azure app service.
For the configuration which under Connection Strings, it should be added with other prefixed. As you know, when you create these connection strings, you need to choose Type:
For these setting, the connection strings are available as environment
variables, prefixed with the following connection types:
SQL Server: SQLCONNSTR_
MySQL: MYSQLCONNSTR_
SQL Database: SQLAZURECONNSTR_
Custom: CUSTOMCONNSTR_
For more details, check this doc: https://learn.microsoft.com/en-us/azure/app-service/configure-common#configure-connection-strings
Setting Environment Variables
In Azure Portal, locate your app service
On the left pane, click Configuration
Under Application settings, click "New application setting"
Fill in the name and value for the environment variable
Click "OK", then at the top, click "Save"
Accessing Environment Variables
With PHP
Replace ENV_VAR_NAME with your own environment variable name.
$var = getenv('ENV_VAR_NAME');
With CLI - Linux
You can use your preferred SSH client, but in this case I'll use the one in Azure Portal.
In Azure Portal, locate your app service
On the left pane, click "SSH"
Click "Go"
Type printenv ENV_VAR_NAME, replace ENV_VAR_NAME with your environment variable.
I found this article which explains a little bit more how the whole stuff works.
https://omgdebugging.com/2018/10/05/how-to-export-environment-variables-in-azure-web-app-for-containers/
However i sticked to this article and used the provided workaround. If somebody knows a better solution, please let me know
I'm able to successfully call my functions and make them do what I want them to do. The problem is that it doesn't look like the logs are being saved anywhere and I don't see how I can view them. Which I'll want to do in the event of an error. As a test I have my working function just doing a log.Info as soon as it's called. When testing locally it prints the message to the console. I believe I've enabled everything correctly but let me explain what I've done in case I didn't.
In my app service, under Monitoring -> Diagnostic Logs, I have enabled everything. Application Logging (filesystem) verbose, Application Logging (Blob) verbose (with the storage location set), detailed error messages and failed request tracing turned on.
In my function, I'm using the TraceWriter object that's passed to my run method (I started from a template).
Please note that functions are set to require authentication. If I click on the "Monitor" tab nothing appears. It just says "Loading..." forever and there's no information. Perhaps this is because of the authentication?
I used the Azure Storage Explorer to browse to my blob. The "log" blob exists, and I do see a set of nested directories that lead up to now. However it just contains a 354 byte file that contains a few lines of some random info. This file never seems to update or get larger.
I used FTP to try and browse to where the logs might be, but there's no directory on there that contains any log files.
I also went to KUDU for my function app ({myfunctionapp}.scm.azurewebsites.net/azurejobs/#/functions). While I do see that my function was called successfully, I don't see anything from the call to log.Info anywhere.
I tried using a different logger, and as a test did: System.Diagnostics.Trace.TraceError("test error");
I also don't see this message appearing anywhere.
Am I missing something as far as set up goes? Is the problem the fact that I require authentication? If it's the latter, is there still a way to view logs? I definitely have to have auth enabled. Thanks. And if it helps, below are links to what my settings and the monitor tab look like.
Settings: https://postimg.org/image/u57m2xbl5/
Monitor: https://postimg.org/image/uou10arch/
Authentication should not cause any problems with logging and Log.Info should work out of the box, no setup required.
I highly recommend that you enable AlwaysOn for your dedicated function app. The long loading of the Monitor tab could be because your site is in a 'cold' state, where it takes longer to start up.
If you go to {myfunctionapp}.scm.azurewebsites.net/DebugConsole and navigate to LogFiles/Application/Functions do you see any expected logs there? Also, when you run a function from the portal do you see logs in the log window?
Same thing happened to me if I had Fiddler open....close Fiddler and all is good.
I can't go into details unfortunately, but I'll try to be as thorough as possible. My company is using AWS Beanstalk to deploy one of our node services. We have an environment property through the AWS configuration dashborad, the key ENV_NAME pointing to the value in this case one of our domains.
According to the documentation, and another resource I found once you plug your variables in you should be able to access it through process.env.ENV_NAME. However, nothing is coming out. The names are correct, and even process.env is logging out an empty Object.
The documentation seems straight forward enough, and the other guide as well. Is anyone aware of any extra steps between setting the key value pair in the dashboard, and console logging out the value once the application is running in the browser?
Turns out I'm an idiot. We were referencing the environment variable in the JavaScript that was being sent to the client. So, we were never looking for the env variable until after it was off the server. We've added a new route to fetch this in response.
We've got a new server, and I am trying to set it up for our website.
I got a new application for the engineers set up in the Application Pools called eng_app, then added our applications to it.
Now, we have been given an external drive that these applications need to be on, but I can't seem to edit or delete the existing applications.
I tried following the Microsoft Technet Article • Remove an Application (IIS 7) but, as you can see in the screenshot, those are incorrect.
C:\Windows\System32\inetsrv>appcmd delete app "eng_app/drawing"
ERROR ( message:Cannot find APP object with identifier "eng_app/drawing". )
C:\Windows\System32\inetsrv>appcmd delete app "/eng_app/drawing"
ERROR ( message:Must specify the APP object with identifier or "APP.NAME" parameter. )
Could someone tell me what I missed here?
Using Powershell
Go to folder
cd C:\Windows\system32\inetsrv
List all applications to get the correct APP.NAME
.\appcmd list app
Delete the application using fullname for <APP.NAME>.Ex.: "Default Web Site/The.Application".I mean, you must put it with web site name including the double-quotes.
.\appcmd delete app <APP.NAME>
OK, it looks like you can't do it either through the command line or using the Application Pool interface.
After stopping the webservice, what I did was:
go down to the list of Sites and select my application from the list,
click Basic Settings...
change the Application pool with the Select... button and edit the Physical path
Afterwards, you can restart the webservice.
There might be a better way, but this is how I did it.
appcmd delete app eng_app/drawing
I have a ASP.NET MVC web application project that I want to deploy to my IIS webserver. The site tree is set up thusly:
SERVERNAME(myDomain\Username)
Application Pools
Sites
Default Web Site
MyProjectSite
bin
Content
...
Views
I am trying to deploy to the MyProject site. See below settings that I am using versus the errors I am returning. I am apparently not specifying my site path correctly, but for the life of me, I can't figure out what it should be.
The following settings stay the same between iterations:
/p:DeployOnBuild=True /p:DeployTarget=MsDeployPublish /p:CreatePackageOnPublish=False /p:MSDeployPublishMethod=WMSvc /p:AuthType=Basic /p:Username="myUserName" /p:Password="MyPassword" /p:AllowUntrustedCertificate=True
Specify SiteName/ as IISAppPath:
Parameters:
/p:MsDeployServiceUrl="https://serverName:8172/MsDeploy.axd?Site=MyProjectSite" /p:DeployIisAppPath="MyProjectSite/"
Error:
Could not complete an operation with the specified provider ("createApp") when connecting using the Web Management Service - I don't want to create a new site. I want to sync the content that is already there.
Specify IISAppPath as Root (supposing that the sitename in the URL is used)
Parameters:
/p:MsDeployServiceUrl="https://serverName:8172/MsDeploy.axd?Site=MyProjectSite" /p:DeployIisAppPath="/"
Error:
Could not complete an operation with the specified provider ("iisApp") when connecting using the Web Management Service - Looks like it is trying to access the Default WebSite or something (to which I have purposefully NOT given myself rights).
Specify IISAppPath as empty string(supposing that the sitename in the URL is used)
Parameters:
/p:MsDeployServiceUrl="https://serverName:8172/MsDeploy.axd?Site=MyProjectSite" /p:DeployIisAppPath=""
Error:
The "ConcatFullServiceUrlWithSiteName" task was not given a value for the required parameter "SiteAppName" - So it interprets "" as actually a null value thus breaking an attempt to concatenate it.
Specify no site attribute in the URL but SiteName/ as IISAppPath
Parameters:
/p:MsDeployServiceUrl="https://serverName:8172/MsDeploy.axd" /p:DeployIisAppPath="MyProjectSite/"
Error:
Could not complete an operation with the specified provider ("createApp") when connecting using the Web Management Service
Specify no site attribute in URL but SiteName as IISAppPath
Parameters:
/p:MsDeployServiceUrl="https://serverName:8172/MsDeploy.axd" /p:DeployIisAppPath="MyProjectSite"
Error:
Could not complete an operation with the specified provider ("createApp") when connecting using the Web Management Service
Now given that it is running a concatenate on the SiteAppName, it must be combining it with the Site name, yes? What are you supposed to put there to get the site to sync to the root of a site?
Update
In an attempt to figure out the proper path scheme, I have tried to publish using the Visual Studio 2012 Publish dialog. In this case, I am returned an error saying that The request timed out (testing the connection works almost instantly and previewing the changes works but takes a few seconds). I checked the event log, and the tracelog for wmsvc to no avail. Even with trace set to verbose, nothing shows up in the tracelog. I have tried disabling the firewalls on both computers, and nothing seems to work on that front either.
Figured this one out.
The problem stemmed from two settings in the Web Deploy page of the project properties. I had previously set this project up (in the Debug configuration) to copy only the files necessary to run the application, and NOT build a zip package. I neglected however to do anything to those settings for the release configuration.
The reason (confidence level 75%) it was trying to use createApp was because it was deploying from the Zip package it had created. So my IISAppPath settings in those cases were fine, I was just deploying the wrong thing.
I set the Create deployment package as a zip file setting to false, and the Items to deploy dropdown to Only files needed to run this application and everything went off without a hitch.
Incidentally I found out (as referred above) that you can use the Publish Profiles outputted by the Web Publish dialog in Visual Studio (2012 only unfortunately; 2010 you have to do some massaging that I am unsure of). I named mine with no spaces, and supplied the password as an argument as well as the Untrusted Certificate setting. Now MSBuild Arguments in the build definition for TFS look like this:
/p:DeployOnBuild=True;PublishProfile=NameOfPublishProfile /p:AllowUntrustedCertificate=True /p:Password=PleaseVerifyMe
