If iptables is not installed, e.g. in the CentOS 8 cloud image, and Docker iptables management is enabled, we get the following error:

Failed to find iptables: exec: \"iptables\": executable file not found in $PATH
failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: Iptables not found
