Description

When setting IP restrictions for Azure Container Apps using the Azure Portal or CLI, it appears that the CIDR notation is not always necessary for a single host (no errors are reported).
IP restrictions for Container Apps.

az containerapp ingress access-restriction set --name example-app --resource-group example-app-rg --rule-name "my allow rule" --description "example of rule allowing access" --ip-address 192.168.0.1 --action Allow

Given that the native Azure behavior allows IP restrictions without requiring CIDR notation, should we not update the Terraform provider to align with this functionality? This would simplify configuration processes and reduce potential discrepancies between direct Azure usage and Terraform configurations.

Thanks @sugar-cat7. Could you take a look at the suggestions left in-line as well as update the docs for this property? Once that's done and provided the tests pass this should be good to go.

This can be achieved by specifying multiple validation functions

Suggested change

	ValidateFunc: validation.IsIPAddressOrCIDR,
	ValidateFunc: validation.Any(validation.IsCIDR, validation.IsIPAddress),

[sugar-cat7]

Thank you. I overlooked the any validator.

Then this can be removed

Suggested change

	// IsIPAddressOrCIDR validates if the input is either a valid IP address or a CIDR notation
	func IsIPAddressOrCIDR(i interface{}, k string) ([]string, []error) {
	warningsIP, errorsIP := IsIPAddress(i, k)
	if len(errorsIP) == 0 {
	return warningsIP, nil
	}
	warningsCIDR, errorsCIDR := IsCIDR(i, k)
	if len(errorsCIDR) == 0 {
	return warningsCIDR, nil
	}
	return append(warningsIP, warningsCIDR...), append(errorsIP, errorsCIDR...)
	}
