class Terracop::Cop::Aws::FaultIntolerant
This cop checks for Autoscaling Groups that can only launch instances in a specific Availability Zone. This creates an availability risk, as if that AZ is lost, the ASG will not be able to launch instances anywhere else.
@example
# bad resource "aws_autoscaling_group" "asg" { vpc_zone_identifier = ["subnet-123"] } # good resource "aws_autoscaling_group" "asg" { # Note that to pass this cop, the two subnets must live in # different AZs. vpc_zone_identifier = ["subnet-123", "subnet-456"] }
