Docker does use bridged networking by default, but it uses linux bridges to
perform the bridging, there is no docker-proxy process. The problem with
docker bridge network is that the address space of the container spawned on
the docker bridge are different than the host network, so you need to

I think you might be a bit confused now this all works. Docker by default
uses bridged networking, which by default spins up a little crappy
docker-proxy process for every port. You can disable docker-proxy and
instead use hairpin routing mode if you have a modern kernel. However, I'm
almost certai
http://github.com/twosigma/cook could be a good fit for this. It supports
scheduling arbitrary jobs within seconds of submission, and it has advanced
QoS features.

Hi,
I'm looking for a scheduler to do distributed builds, i.e. most of the
tasks would be short lived, like a few hundred ms long.
Is there's any Mesos based scheduler that would be a good fit for this?
Any help is appreciated.
Thanks,
-Paulo
PS: I know that Jenkins supports distributed builds
Question is more related to mesos. I am thinking of using docker instead
of native (LXC?) containers but I suspect network performance decrease
which is important on big data workloads.
Can you explain why its not secured In host mode ?

Not sure though but my guess is that Mesos slave is unable to pull the
docker image. Are you using private docker registry ?

Hi Vincent,
What do you mean by native container through Docker? Can you clarify your
question a bit. Also if it's a DC/OS specific question you might want to
post at us...@dcos.io .

Nobody experienced docker vs native container performance ?

The answer to your question is not very simple. I am still figuring this
out myself, but you can look at certain projects such as mesos-dns which
publish SRV records for running docker containers, allowing you to
programmatically find services you have started up. For example, here I
have started u
Yes i guess i understood, so when i star a socker container like wordpress
this app could have the need to contact another container as mysql, here
project calico should be an efficient way to make this.
Ok i will try, just to understand, first i run the mysql, then mesos will
allocate it on a cert
That is a good point - is the executor spun off as a different PID, if so
it would perhaps inherit a different fsize value.

Stefano,
You would want to search for an appropriate image on Docker Hub. Here is
one I have NO experience with: https://hub.docker.com/_/mysql/
You would then need to learn about how the image is expecting to be
configured, so you can set it up appropriately.
This is not really a fully thought
My problem is this, where can i find the mysql container? I have just said
to marathon to rim a wordpress docker container, without specify mysql one.

Marathon does not know it has to run it. You need to tell Marathon to start
mysql container and then tell your wordpress container where is your mysql.

If you run the wordpress container on a different host to the mysql container
and use --link on the command line, does that work?

Hi Aaron
Actually both mesos-dns and calico are running even though these containers
im running are not, yet, using the calico ipaddr specific in json
description.
So i guess it is a problem of bridging, i guess simply specify HOST option
on container field in Marathon UI

--link in docker should really be avoided when using marathon/mesos as it
implies the containers are on the same host, but this will not always be the
case when mesos schedules your containers (also I think it's being deprecated
in docker anyway.. not sure though?).
This problem looks like one
Stefano,
The docker run flag --link is intended to connect the container to another
running container. I do not know how this would operate in marathon.
Perhaps it would be an application group which starts up the mysql docker
image first, then the Wordpress docker image after it.
Thanks,

Thanks *Rad* Gruchalski, actually i'm trying to make a json file that
"translate" this command in marathon:
docker run --name some-wordpress --link some-mysql:mysql -d wordpress
i guess the error is relate to the fact that i'm not specifying --link
some-mysql:mysql
My problem is that i don't know
It says exactly what the problem is.
Start a marathon task with correct environment variables in env and you will be
fine.

I guess because i did not type this commands:

Stefano,
Per your earlier question, "group/image" refers to the path you will see in
the Docker Hub website on the right side, after the "docker pull" command.
In the Jupyter Notebook example I gave you, jupyter is the group, and
notebook is the image, with the / literal separating them.
Thanks,
Thank you June taylor, it is axactly what i was intending.
if it is not disturbing you, i try jupyter notebook as well, just to make
some tests on how to launch marathon.
stay tuned :)

actually i have run this kind of apps through rest api.
Now i want learn how to laung docker files. I found this exaple:

"type": "DOCKER",
"docker": {
"network": "HOST",
"image": "group/image"
},
"volumes": [

Perhaps the "unlimited" keyword is what is not working? What should be
specified for Unlimited?

Stefano,
I hope this information is helpful:
You should specify the docker hub path, which is the what you can see after
the Docker Pull command on the Hub page. In your case, simply the word:
"wordpress" without quotes, is what you would use as the Image.
You will also need to specify port bind
