限制docker 上传速度

然而，你可以使用第三方工具来实现这个目的。一个常用的工具是 trickle，它可以模拟网络带宽。

首先，你需要安装 trickle。在 Ubuntu 上，可以使用以下命令安装：

sudo apt-get install trickle

然后，你可以使用 trickle 来限制 Docker 推送的速度。例如：

trickle -s -u 300 docker push kevinchina/deeplearning:CodeFormerv1.000

在这个例子中，-u 300 表示将带宽限制为每秒 300KB。你可以根据需要调整这个值。

请注意，这种方法并不是 Docker 的原生功能，而是通过使用额外的工具来实现的。

Installation
sudo apt-get install trickle
How to use trickle
Trickle’s syntax is as follows:

trickle -d Download_Bandwidth -u Upload_Bandwidth Command
Here are some examples:

a) Limit the download bandwidth to 10kbps used to transfer a file using ssh:

trickle -d 10 scp file.mp3 10.0.0.1:/home/puntolibre/musica/
b) Limit the bandwidth to 200kpbs of download of a system update through Apt:

trickle -d 200 apt-get upgrade
c) To modify the bandwidth of an application, such as Firefox:

trickle -d 10 -u 10 firefox% u
d) Using trickle to limit wget’s bandwidth

trickle -d 50 wget -O “planet earth.divx” http://video.stage6.com/1402821/.divx

Run trickle like a demon
To start trickle like a daemon and limit ALL bandwidth, use the trickled command:

sudo trickled -d 20 -u 20
… Where the parameters -d and -u respond to the download and upload limit, respectively.

Configuring trickle
Trickle has a configuration file that will allow us to fine-tune some parameters and make them permanent individually for each service.

The configuration file is as follows: /etc/trickled.conf

The simplest configuration file that can be made looks like this:

[ssh] Priority = 1

[www] Priority = 8
With this method we get quite good download speeds and at the same time we can do ssh sessions to the machine that is downloading. Basically, a config file like the one above tells trickle to prioritize ssh transfers over www.

Trickle’s documentation recommends the use of the Time-Smoothing and Length-Smoothing parameters to avoid fluctuations in transfer rates.

[ssh] Priority = 1
Time-Smoothing = 0.1
Length-Smoothing = 2

[www] Priority = 8
Time-Smoothing = 5
Length-Smoothing = 20
These values ​​define the normalization time and length that Trickle applies to the program it is controlling.
