Docker on Mesos With OpenVNet (eng)
This document discusses integrating Docker containers with OpenVNet to provide network isolation and virtual network functions when running containers on Mesos. It provides background on Docker networking and trends in container networking tools. OpenVNet is introduced as an open source software that can build overlay networks and provide network functions like security groups and DHCP for containers. The main topic is integrating OpenVNet with Mesos and Marathon to enable things like assigning containers to isolated virtual networks with their own IP ranges and network functions when scheduling containers on Mesos. A demo is proposed of building such an environment using Marathon API requests.

- 2. The Topics ofToday 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 dockercontainers run under mesos. “What are you talking about?”
- 4. “What are youtalking 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, whatis 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 ▷ Toolslike 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 seemsto aim to build a platform. However, the fact Docker itself is getting a little fat makes some people feel down.
- 8. Otoh, in thefield 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 sourcesoftware 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/

- 11. ▷ Various kindof 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 theenvironment 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, ifwakame-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: https://github.com/qb0C80aE/Mesos_OpenVNet_Integration_Patch ▷ Do you know OpenVNet deeply? check this out: https://github.com/axsh/openvnet
