Configuration in Azure Container App

Question

How to define environment variables for Azure Container App (preview), via CLI or Portal?

I am asking specifically for Azure Container App, not Instances, but there is no such tag yet.

As of November 14th, 2021, there is nothing you can do from the Portal, at App or Environment level.

@François Baronnet , thank you for your question.

Currently you can define environment variables for your Azure Container Apps using Azure CLI or ARM template.

Azure CLI:

az containerapp create --help  
Command  
    az containerapp create : Create a Containerapp.  
...  
Container Arguments  
...      
    --environment-variables -v     : A list of environment variable(s) for the containerapp. Comma-  
                                     separated values in 'key=value' format. If there are multiple  
                                     containers, please use --yaml instead.  
...  
Examples  
...  
    Create a Containerapp with secrets and environment variables  
        az containerapp create -n MyContainerapp -g MyResourceGroup \  
            --image MyContainerImage -e MyContainerappEnv \  
            --secrets mysecret=escapefromtarkov,anothersecret=isadifficultgame  
            --environment-variables myenvvar=foo,anotherenvvar=bar

ARM API Specification:

The following is an example ARM template used to deploy a container app.
