Filters for Network fault about mangle HOT 7 OPEN

Thanks for the suggestion Omar, will try to consider the feature for next mangle release.

Hi @omar91089 ,

If you want to inject network fault to a specific container then you can directly use the network interface of respective container during fault injection. For eg on a host C1 and C2 containers are running and if you want to inject the fault on C1 container, then first step is to find out the network interface of C1 which will be created by docker0 (Virtual bridge interface created by Docker). When you run ifconfig command on linux host it will list a couple of interfaces which includes eth0(or/and eth1 or something else), docker 0 and a couple of other interfaces which will be created by docker0 for respective containers. Once you find the interface name of the container, use it while injecting the fault via mangle.

Thanks,

@ashrimalivmware Thank you for the response. I think this would work out when the bridge networking option is used. I'm trying to inject faults on an IPvlan (https://docs.docker.com/network/ipvlan/) network. I get only eth0 on the host and using that would impact every container on the network. I think filtering would be one solution to isolate the container in this setup. I'm not sure if there is any other way. Please let me know if this makes sense

@omar91089 Currently Mangle doesn't support such isolation.

@ashrimalivmware Got it. Are you planning to consider it in future releases?

from mangle.

@ashrimalivmware I've implemented the filters for destination IP and port using the approach described here. I would like to discuss about it with you in more detail.
I also want to discuss about the PR #103 one of my work colleagues @vmaligireddy has opened on the project. Would it be possible to connect over a call?
