Override running tc delay command

[deanstef]

I have a network of docker containers who, by default, run a tc delay command using the built-in iproute2 tc.

I want to use the pumba netem delay command to inject random delays within the network above. However, running pumba delays have no effect causing a RTNETLINK answers: File exists error. To override the current delay, tc has the option replace to be launched with the new delay invocation:

e.g. sudo tc qdisc replace dev eth0 root netem delay 100ms

Is there a way to invoke such replace option within a pumba command?
