Common Mistakes

Using the resource group name instead of a location.

Using the container app name instead of a location.

The --location parameter specifies the Azure region where the container app environment will be created. 'eastus' is a valid Azure region.

💡 Hint

Common Mistakes

Using the environment name instead of a number.

Using a command keyword instead of a number.

💡 Hint

Common Mistakes

Using 'secrets' instead of 'environmentVariables'.

Using 'env' or 'variables' which are not valid properties here.

The environment variables are set under configuration.environmentVariables in the container app settings.

Fill all three blanks to create a container app with ingress enabled on port 80 and replicas set to 2.

Azure

az containerapp create --name myApp --resource-group myResourceGroup --environment myEnv --image myImage --ingress [1] --target-port [2] --min-replicas [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'disabled' for ingress when enabling is needed.

Setting the wrong port number.

Setting replicas to 1 instead of 2.

To enable ingress, use 'enabled'. The target port is 80 for HTTP traffic. The minimum replicas set to 2 scales the app to two instances.
