We have to use this feature with Terraform.

Any update on this?

Like others here, I'm also looking forward to native support for the aws_cloudfront_distribution_tenant resource.

In the meantime, I've created a workaround using a null_resource with local-exec provisioners. This solution handles both the create and destroy lifecycles, including the necessary logic to disable the tenant and wait for the operation to complete before deletion.

Prerequisites: This workaround requires the AWS CLI and jq to be installed on the machine running Terraform.

Here is the code for anyone who needs a temporary solution. I've created it as a self-contained module for easier use.

main.tf

resource "null_resource" "cloudfront_tenant" {
triggers = {
distribution_id = var.cloudfront_distribution_id
tenant_name = var.tenant_name
tenant_domain = var.tenant_domain
certificate_arn = var.certificate_arn
}

provisioner "local-exec" {
when = "create"
command = <<-EOT
echo "Creating tenant '${self.triggers.tenant_name}'..."
aws cloudfront create-distribution-tenant
--distribution-id ${self.triggers.distribution_id}
--name ${self.triggers.tenant_name}
--domains Domain=${self.triggers.tenant_domain}
--enabled
--customizations '{"Certificate": {"Arn": "${self.triggers.certificate_arn}"}}'
EOT
}

provisioner "local-exec" {
when = "destroy"
command = <<-EOT
echo "Fetching status for tenant at domain '${self.triggers.tenant_domain}'..."
TENANT_INFO=$(aws cloudfront get-distribution-tenant-by-domain
--domain ${self.triggers.tenant_domain})

if [ -z "$TENANT_INFO" ]; then
echo "Tenant not found. Nothing to delete."
exit 0
fi

TENANT_ID=$(echo "$TENANT_INFO" | jq -r '.DistributionTenant.Id')
ETAG=$(echo "$TENANT_INFO" | jq -r '.ETag')
IS_ENABLED=$(echo "$TENANT_INFO" | jq -r '.DistributionTenant.Enabled')

if [ "$IS_ENABLED" = "true" ]; then
echo "Tenant is enabled. Sending disable command..."
aws cloudfront update-distribution-tenant
--id "$TENANT_ID"
--if-match "$ETAG"
--no-enabled
else
echo "Tenant is already disabled. Proceeding to delete."
fi

echo "Waiting for operation to complete..."
TIMEOUT=600
INTERVAL=20
SECONDS_WAITED=0

while true; do
LATEST_INFO=$(aws cloudfront get-distribution-tenant-by-domain
--domain ${self.triggers.tenant_domain})

CURRENT_STATUS=$(echo "$LATEST_INFO" | jq -r '.DistributionTenant.Status')

echo "Current status: $CURRENT_STATUS. Waiting..."

if [ "$CURRENT_STATUS" != "InProgress" ]; then
echo "Operation finished with status: $CURRENT_STATUS."
ETAG=$(echo "$LATEST_INFO" | jq -r '.ETag')
break
fi

if [ $SECONDS_WAITED -ge $TIMEOUT ]; then
echo "Error: Timed out after $TIMEOUT seconds."
exit 1
fi

sleep $INTERVAL
SECONDS_WAITED=$((SECONDS_WAITED + INTERVAL))
done

echo "Deleting tenant '$TENANT_ID'..."
aws cloudfront delete-distribution-tenant
--id "$TENANT_ID"
--if-match "$ETAG"

echo "Tenant deletion command sent successfully."
EOT
}
}
