simulate latency to a container.md

Note: If you are using podman feel free to s/docker/podman/g it should work the same.

1. Ensure that container1 has the NET_ADMIN capability
   • docker inspect --format='cap_add: {{.HostConfig.CapAdd}}' container1
2. Install tc on container1:
   • apt-get install libterm-readline-perl-perl -y && apt-get update && apt-get install iproute2 iputils-ping -y
3. Configure latency on the container1:
   • tc qdisc add dev eth0 root netem delay 1000ms
4. verify there is latency between two images:
   • docker exec container2 ping container1
   • Note: if container2 does not have ping ➜ docker exec -u 0 container2 bash -c "apt-get update && apt-get install iproute2 iputils-ping -y"

For items 2 and 3 you can run those either:

• one off: docker exec -u 0 container1 bash -c "<CMD>"
• in a shell: docker exec -u 0 -it container1 bash
