the presentation material for cloudmix study meeting #11.

1. @CloudMix #11 (Study Meeting about Containers)
Docker on Mesos with OpenVNet

2. The Topics of Today
Let's enhance Mesos and Marathon to integrate them with
OpenVNet, which gives docker-containers* network
isolation and virtual network functions.
* in this case, the targets are “system containers”.

3. Here are docker containers run under mesos.
“What are you talking about?”

4. “What are you talking about?”
I made patches which let containers run on arbitrary
virtual networks like below.
You can apply some network functions there.
DNS
DHCP
Security
Group

5. Before that, what is Docker Networking like?
▷ Basically, it works on a single host
▷ It takes advantage of Linux Networking functions
▷ Services are exposed with ports
About Docker Networking

6. Recent trends
▷ Tools like flannel, weave have appeared that can work with
container managers like kubernetes.
▷ socketplane
Since Docker acquired them recently, socketplane could be
the standard networking function of it.

7. Recent trends
Docker seems to aim to build a platform.
However, the fact Docker itself is getting a little fat makes some
people feel down.

8. Otoh, in the field of SDN...
They have been around for some time.
▷ edge-overlay networking
▷ network function virtualization on distributed edges
▷ to support containers (btw, what does “support” mean in this case?)
▷ a de facto standard networking api (Neutron?)

9. OpenVNet?
An open source software which builds overlaid networks and
gives them virtual network functions.
It's been developed by Axsh* co., LTD. Mainly.
OpenVNet:
▷ was spinned-out from wakame-vdc
▷ builds virtual networks with MAC2MAC and GRE tunnels
▷ gives network functions like security groups, dns, dhcp
* http://axsh.co/

10. Something similar to this
▷ VMWare NSX
▷ midonet
▷ OpenContrail
▷ OpenDaylight OpenDOVE(how is it going?), VTN
etc.

11. ▷ Various kind of tools related to docker networking have come
▷ However, the networking products from SDN field can realize
more complex and powerful network environment.
▷ Why don't you integrate them with Mesos/Marathon/Docker?
The main subject of today

12. Demo
Let's build the environment like below with json request for
marathon, and “Scale” button.
eth0
10.0.100.0/24
DHCP
eth0
10.0.100.0/24
DHCP
eth1
192.168.0.0/24
DHCP
The same IP range
(isolated)

13. Conslusion
Frankly speaking, if wakame-vdc suppoted Docker, you didn't
need to enhance like this ..?
▷ Maybe, you're right.
▷ However, I've learned a lot in the process of researches or
source code reading of Mesos and Marathon.

14. Patches and documents
▷ The patches what I made are here:

▷ Do you know OpenVNet deeply? check this out:

15. Thank you
