Is there a way to list out the read-only app service environment variables for an Azure app service? I need the built-in variables listed here in the first section: https://learn.microsoft.com/en-us/azure/app-service/reference-app-settings?tabs=kudu%2Cdotnet. For example, the value of WEBSITE_HOSTNAME or SERVER_PORT
I do not need to set custom variables in Configuration => Application Settings. I need an easy list of all environment variables.
When we deploy Azure Web App Service by default app will be set with read-only Environment Variables.
We can override the existing Environment variables in Configuration => App Settings section of the deployed Web App.
We can check the environment variables in Azure Portal KUDU Console.
Path to open KUDU Console
Open Azure Portal => Select your App Service => Under Development Tools select Advanced Tools => Click on Go
Way 1 :
In KUDU Console Click on Environment, list of default and the Variables you created in App settings will be seen.
Way 2 :
In KUDU Console Click on Debug console and select CMD , run printenv command.

I have several Azure Functions Apps (c#, javascript and python) and after some time they were all randomly set to Read Only mode. The strange thing is that only one of these 3 function apps were updated before this happened. I know that this is not necessarily a problem, but I want to be able to make edits from the portal.
I can't open App Service Editor
I can't set the app to Read/Write from Function App Settings -> Function app edit mode
I also tried using "func azure functionapp publish myAzFuncAppName --nozip", but with the same result
Of course. Please notice that if the function is 'deployed' to Azure, what will be deployed is the compiled file.
For example, if you deploy C# function app, what will be deployed is the dll file. So this is why it is readonly.
Changes to the code should be done before compiling them into corresponding 'cannot be edited' files, which requires special attention.
But for the modification of the declarative part and the configuration part of the function, this is possible, the specific steps are as follows:
Declarative part:
Then click Debug Console > cmd:
Go to site\wwwroot[yourfunctionname], and there will be a function.json.
Click the 'pen' to edit and don't forget to save.
Configuration part:
You can change the settings from Azure Portal or by editing the application settings. FUNCTION_APP_EDIT_MODE allows values readwrite and readonly, a
Just deleted the Azure Function App, created a new one, transferred the code in the new one and deployed -> still read only, but now I was able to open "App Service Editor" and remove "generated by..." from function.json and then set "Read/Write" from Function App Settings -> Function app edit mode.
Still... I can't see/edit the code of the function, only of function.json and if I redeploy using Azure extensions of Visual Code or powershell with --nozip attribute, the "generated bla bla" appears again :(
When the application runs from package, the files are loaded from that package. Hence those files are not editable.
You need to set WEBSITE_RUN_FROM_PACKAGE : 0 in app settings and redeploy the application again to make the function app editable.

UPDATED:
You can deploy functionapp through command line from visual studio code. Try below command.
func azure functionapp publish --nozip
The nozip flag would set Run-From-Package mode off .
you can access other information regarding that command with func azure functionapp publish --help
I have a docker image being deployed from Azure Container Registry. Everything works fine except that I expect to be able to
see environment variables being passed to my running docker image from the Application Settings configured in the portal. It is a Node app accessing environment variables with process.env.VariableName.
As an example its says here
https://blogs.msdn.microsoft.com/waws/2017/09/08/things-you-should-know-web-apps-and-linux/#SetEnvVar …
"App Settings are injected into your app as environment variables at runtime"
I have tried the following.
Setting Applications Settings in the Azure Portal. These are supposed to get passed to the running Docker image as per the documentation but process.env.VariableName in my Node application is not set.
I have tried using a Docker compose file that sets the environment variables but again process.env.VariableName is empty.
I have even updated the VSTS build arguments passing the Variable to my Docker file on build which in turn sets the environment variable. Again no variable passed to the running Docker image.
My conclusion is that custom environment variables are not allowed in Azure Web App for Containers?
Am I doing something wrong?
As per the documentation the app settings are injected into the process as environment variables, however the environment variable name is prefixed with APPSETTING_, so in your Node application you would need to access the app setting with process.env.APPSETTING_VariableName.
Is it possible to set azure app service application settings (especially env variables) via deployment?
We are using local git repositories to deploy our NodeJS application to different azure appservices.
There are several environment variables required to run the application. I'd like to know if there is a way to insert those automatically while deploying the application so I do not have to set them manually for each application.
If its possible how does azure handles changes in the environment settings if I changed a variable afterwords? For example if I have sensitive data that I have to enter after deployment directly into the env variable?
Here's an example. Variables: Name=InitialValue
VAR_1=Test1234
VAR_2=Hello World
USERNAME=
PASSWORD=
USERNAME AND PASSWORD need to be empty an filled afterwords directly via azure portal. Now I redeploy. What happens to my USERNAME and PASSWORD entries? What happens if I change the value of VAR_1? In this case I'd like to have the environment variable changed.
In azure app service the environment variables can be set via Application Settings > App Settings.
It has a 'key-value' format where you can enter the variable name and its value.
Then in the code you can read them as "process.env.Username " and so on.
I have an ASP.NET MVC app deployed to Microsoft Azure App Service and am having some trouble with the appSettings and connectionStrings values.
I have some values set in the web.config and some values overriding them in the Application Settings tab of the App Service. I want to quickly and easily view the final values to check that the settings are being picked up correctly.
How can I do this?
Note: I've tried using az webapp config appsettings list but this only seems to bring back what is configured in the Application Settings of the App Service and not the merged results of combining with web.config.
No Azure API will return values that include settings that come from your web.config file.
The only way to get this is to ask the config system within your own runtime. e.g. Use code along these lines:
foreach (string name in ConfigurationManager.AppSettings)
{
string val = ConfigurationManager.AppSettings[name];
...
}
foreach (ConnectionStringSettings settings in ConfigurationManager.ConnectionStrings)
{
string connStr = settings.ConnectionString;
string provider = settings.ProviderName;
...
}
This will give you the effective values that are applied to your app.
You may also use the following blades in Azure Portal (under Development Tools section):
Console
In order to see the file, you may use type command, e.g.:
type web.config
Advanced Tools
This points to the Kudu service.
You may see files deployed when navigating to Debug Console > Choose either CMD or PowerShell. Then navigate to your config directory (e.g. site/wwwroot) and choose to either download or edit file.
App Service Editor
App Service Editor is a relatively new tool in Azure toolset. Default view is a list of files, so you can browse all hosted files, including configuration ones.
You can view all of your runtime appSettings, connection strings and environment variables (and more..) using azure KUDU SCM. if your application address is "https://app_name.azurewebsites.net" you can access it in the address "https://app_name.scm.azurewebsites.net" or from azure portal
With kudo REST API, you can get the settings, delete or post them in this address https://app_name.scm.azurewebsites.net/api/settings

I try to use MVC6 and I want to use new feature "Changing configs by environment" in my apps
So as far as I understand I can choose proper config by changing environment variable ASPNET_ENV. I know two ways to change value of this variable
1) I change variable at Debug tab at Project Properties
2) I change variable at Azure Portal for my Azure Web Site
But how can I specify this variable in IIS after publishing website?
You can set specific user for the AppPool of your website, and then set environment variable for the user.
