Docker the configuration of network resource restriction

One, the following is my test results:

For the speed limit of 100m below, in fact, the type of hard disk and read and write speed has no effect, but how to limit the speed of more than 150m, or infinite speed, then the hard drive is definitely ssd>sas>sata, so it is recommended to use the SAS disk as a Docker mount partition.
Openvswitch The default official document provides a speed limit method "rate limiting VM traffic using QoS policing", address is http://openvswitch.org/support/ config-cookbooks/qos-rate-limiting/, this speed limit can only upload speed limit, download no way, so you have to use other QoS to do the restrictions.

Two, the following is the specific speed limit script

#!/bin/bash
#filename: modify_docker_container_network_limit.sh
#author:D Eng Lei
#email:d l528888@gmail.com
Op=$1
Container=$2
Limit=$3 # MBITS/S
If [-Z $] | | [-Z $]; Then
echo "Usage:operation container_name limit (default:5m)"
echo "Example1:i want limit 5m in the Container:test"
echo "The command Is:bash ' basename $ ' limit test 5"
echo "Example2:i want delete network limit in the Container:test"
echo "The command Is:bash ' basename $ ' ulimit test"
Exit 1
Fi
If [-Z $];then
limit= ' 5m '
Fi
If [' Docker inspect--format ' {{. State.pid}} "$container &>>/dev/null && echo 0 | | Echo 1 '-eq 1];then
echo "No this container: $container"
Exit 1
Fi
ovs_prefix= ' VETH1PL '
Container_id= ' Docker inspect--format ' {{. State.pid}} "$container"
Device_name= ' echo ${ovs_prefix}${container_id} '
if [$op = = ' Limit '];then
For V in $device _name; Todo
Ovs-vsctl set Interface $v ingress_policing_rate=$ ((limit*1000))
Ovs-vsctl set Interface $v ingress_policing_burst=$ ((limit*100))
Ovs-vsctl set port $v qos= @newqos----id= @newqos create QoS TYPE=LINUX-HTB queues=0= @q0 other-config:max-rate=$ (limit*1 000000)----id= @q0 Create queue other-config:min-rate=$ ((limit*1000000)) other-config:max-rate=$ ((limit*1000000)) &>>/dev/null && Echo ' modify success! ' | | Echo ' Modify fail! '
Done
elif [$op = = ' Ulimit '];then
For V in $device _name; Todo
Ovs-vsctl set interface $v ingress_policing_rate=0
Ovs-vsctl set interface $v ingress_policing_burst=0
Ovs-vsctl Clear Port $v QoS &>>/dev/null && Echo ' modify success! ' | | Echo ' Modify fail! '
Done
Fi
This script is used, the speed limit can be directly targeted to download and upload, and the restrictions are unified effective, such as I limit a container bandwidth of 5m, then download and upload the speed limit is 5m, the unit is bit is not byte.

Three, the following is the use of the method:

[Root@docker-test3 tmp]# SH modify_docker_container_network_limit.sh
Usage:operation container_name Limit (default:5m)
Example1:i want limit 5m in the Container:test
The command is:bash modify_docker_container_network_limit.sh limit test 5
EXAMPLE2:I want delete network limit in the Container:test
The command is:bash modify_docker_container_network_limit.sh ulimit test
Four, the following is the test process:

The test method is:

Find another host 172.16.1.126, then DD generates a 100m file/tmp/test_client.iso, download this file to test download speed, and generate 100m files in native DD/tmp/test_ Server.iso uploaded this file to the 172.16.1.126 test upload speed.
