How to add .env file to container app

Hi @Umesh Edirisingha Greetings! Welcome to Microsoft Q&A forum. Thank you for posting this question here.

Azure Container Apps also provides couple of different options through Azure CLI or Powershell to Add/Update environment variables.

While creating a Container App you can use the following Azure CLI command to pass multiple environment variables by a space-separated values in the 'key=value' format.

az containerapp create -n my-containerapp -g MyResourceGroup \
    --image my-app:v1.0 --environment MyContainerappEnv \
    --secrets mysecret=secretvalue1 anothersecret="secret value 2" \
    --env-vars GREETING="Hello, world" ANOTHERENV=anotherenv

If you are trying to provide environment variables to an existing Container App, you may az containerapp update command and achieve the same. Please refer the document link to get more information on how to Configure the environment variables through Azure CLI

Here is another option to Configure the environment variables through Powershell

You can iterate the contents of your .env file through the following script and automate the addition of entries.

Get-Content .env | ForEach-Object {
    # Split the line into the variable name and value
    $varName, $varValue = $_.Split('=')

    # Do something with the variable name and value
    Write-Host "Variable name: $varName, Value: $varValue"
    # Put in the commands from configuring through PowerShell option

    # Wait for 5 second
    Start-Sleep -Seconds 5
}

Please note that I have put a five second delay in the above loop as the script iterates through the file contents and call Update-AzContainerApp -TemplateContainer $containerTemplate command. This is just a caution to allow the command execution to be done processing adding an environment value. Please test this script on a test app and adjust the wait time as needed.
