Linux docker shaper: Управление траффиком внутри контейнера

Ограничение траффика в контейнере

В примере 6142712b1eef это индентификатор контейнера
Получить PID процесса докера (внутри контейнера этот процесс будет иметь PID=1)

docker inspect -f '{{.State.Pid}}' "6142712b1eef"

export DOCKER_CONTAINER_UUID="6142712b1eef"

mkdir -p /var/run/netns

ln -sf /proc/$(docker inspect -f '{{.State.Pid}}' "${DOCKER_CONTAINER_UUID}")/ns/net "/var/run/netns/${DOCKER_CONTAINER_UUID}"

# ip netns
6142712b1eef (id: 6)

modprobe  ifb numifbs=10

ip link set  dev ifb0 netns ${DOCKER_CONTAINER_UUID}
ip link set  dev ifb1 netns ${DOCKER_CONTAINER_UUID}

ip netns exec ${DOCKER_CONTAINER_UUID} bash
