To build

This will also build any java files in the current directory in the container.

docker build -t javaapptest .

To create the node network

Only needs to be done once.

docker network create --subnet=172.18.0.0/16 nodenet

To Run (for example, node 1)

docker run -it -p 8080:8080 --cap-add=NET_ADMIN --net nodenet --ip 172.18.0.21 javaapptest 1 172.18.0.80:44

To Run (node 2):

docker run -it -p 8081:8080 --cap-add=NET_ADMIN --net nodenet --ip 172.18.0.22 javaapptest 2 172.18.0.80:44

To Block Nodes 2 and 3 on Node 1

Using the block=ip http query parameter.

curl "http://localhost:8080/?block=172.18.0.22&block=172.18.0.23"

To unblock Node 2 on Node 1

Using the unblock=ip http query parameter.

curl "http://localhost:8080/?unblock=172.18.0.22"

To randomly drop 10% of incoming packets to Node 1

Using the indrop=p http query parameter. Note that these are incoming packets -- not outgoing. IPTABLES notifies higher layers when outgoing packets are dropped invalidating the testing.

curl "http://localhost:8080/?indrop=0.1"

Note that multiple commands can be appended on one URL.

ENJOY!
