How and where to define an environment variable on Azure
Solution 1:
I assume you are using Azure App Service (formerly known as Azure Websites).
To define your own environment variable, click to your site → All Settings → Application settings:
Add an app setting in the "App settings" section:
You can verify the value from the debug console.
Going to https://{your site name}.scm.azurewebsites.net/DebugConsole:
Solution 2:
I came across this question when facing the same problem myself. Well, just to give a clearer answer which I found at blog.elmah.io.
All you need to do is:
- Include the new appsetting.{env}.json in the publishOptions in file
project.json
. - Go to Azure Portal and open the web application.
- Select application settings.
- Add an entry for ASPNETCORE_ENVIRONMENT and set it to whatever you want.
That's it.
Solution 3:
In the new version 2021 go to the resource -> Configuration.
Then click on "New application settings".
Then add "ASPNETCORE_ENVIRONMENT" as key and click on OK then Save.
Note that you must have the appsettings.(environment).json file for .Net Core.
Solution 4:
I know OP specified in the portal, but command line is more repeatable. To do it using Azure CLI:
az webapp config appsettings set -n $webappname -g $resourceGroupName --settings ConnectionStrings__Default=$connectionString
To set an environment variable ConnectionStrings__Default
to the variable $connectionString
Solution 5:
(2019 version) Navigate to your AppService in the Azure cloud portal then Configuration.
