Qos between dockers

Hi All, here starts another week!!

 

I went to access my website this morning (which I host and run from a docker container) and realised that it was unresponsive. I realised that another service running from within another container was sapping all the available b/w to the outside world. I could limit the b/w available to other services to ALWAYS leave enough for the container running my website but that seems inefficient to me - especially as it is for my own personal use and I don't get many visitors.

 

So ..... does anyone know of a method to apply Qos settings in this scenario. I have Qos on my dd-wrt router but that works with MAC addresses and IP addresses. Given the these dockers are all on one host machine I don't think that will be the answer. Unless I have missed something.

 

Anyone got any ideas?

I wish I could apply a different ip address to each docker. If I could then I would just use my router for QoS.

There is a thread here about doing that.  Search is your friend

 

A bit harsh to ping me for that I feel.

 

I searched qos and bandwidth throttling and neither brought back the thread you have pointed me too.

 

However, thank you for pointing me at it anyway. I'll take a look.

danioj, look at the post Squid quoted, it wasn't in reference to your OP mate.  And then he posted the link anyway, he's a nice guy Squid, although there's something a bit fishy about him. ;)

 

I think you've raised an interesting point though and one that will affect me as well sooner or later, I don't have any answers at the moment, but if I find anything out I'll let you know and you can do the same.

 

QOS is something I've only recently started looking into, networking is a definite weak point of mine.

@Squid: Jeez, sorry man. Over react much. God I am having a bad week. Hand up, I was wrong.

 

@CHBMB: I have been looking into this this morning.

 

**Firstly I apologise if what I have written below is technically wrong - it has been many years since I have fiddled at this level**

 

I was having a think over coffee at work this morning and I started doodling on a bit of paper. What about IP Address aliasing and virtual interfaces in the Unraid OS and then binding a specific container to that interface? what I mean is something like this:

 

So for example lets say I want to create four additional virtual interfaces and bind four IP's in the same range as the physical interface which is 192.168.1.2 (range: 192.168.1.40-44) to the one card I would do that via virtual interfaces or alias's. If my memory serves me I would do this via alias files. I believe the default interface has a config/script file (somewhere but I don't know where on Unraid called in using my example ifcfg-eth0) and I would create copies of this for each virtual interface I wanted to create for each four (ifcfg-eth0:0 - 3).

 

We could then edit the virtual interface files we have just created with different Device and IP Address Settings. Perhaps Like this:

 

DEVICE="eth0"

IPADDR=192.168.1.2

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

HWADDR=00:00:00:00:00:00

 

DEVICE="eth0:0"

IPADDR=192.168.1.40

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

HWADDR=00:00:00:00:00:00

 

DEVICE="eth0:1"

IPADDR=192.168.1.41

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

HWADDR=00:00:00:00:00:00

 

....and so on and so on.

 

I "Think" you would leave the H/W Address alone as this wouldn't change. You are just assigning multiple IP Addresses to the same NIC. I also "Think" this file has more options in it but I can't remember.

 

You would then reset the network service and then that "should" be it. I think!

 

"Surely" then if the the Unraid OS has these additional interfaces there should be a way to bind a specific container to that IP?

 

OK - now I am Waaaaay out of my depth!

 

Next coffee break is in a few more hours so I'll look more then!

Doesn't docker use a bridge docker0 as an access to the eth0?  Or am I getting muddled up?

 

PS Good of you to apologise, takes a man to admit to his mistakes, and it's not like you were rude about it either..
