コンテナの速度による仮想マシンのセキュリティ

16. Shared kernel. Security via cgroups

17. Kata Containers

22. OpenStack on Containers
• Deployment Tools
• Kolla-Ansible, openstack-helm, Your own tool
• Don't Do Things with Containerized OpenStack
• See no real benefit in containerized OS deployment
• What process (projects) are containerized?
• cinder-volume with ceph rbd driver
• Simplified upgrades / rollbacks

23. Containers on OpenStack
• deploying your containers on OpenStack
• k8s
• Magnum is most used
• Pain points for using containers when you deploy and
operate containers
• Magnum in Mitaka broke when CoreOS version was changed -
because of Heat templates maybe?
• Containers in VMs on openstack is inefficient compared to
containers on bare metal server
• VM -> bare metal container networking
• Bloomberg is going to use Calico (https://www.projectcalico.org)
specifically for VM <-> containers-in-k8s

24. Neutron pain points
• Is there any good document to understand and catch-up
current Neutron well?
• Official Docs?: https://docs.openstack.org/neutron/latest/
• APi reference team makes api-ref newer
https://developer.openstack.org/api-ref/network/v2/
• I'd like to use my home router as a dhcp.
• OpenStack security groups are not rich enough to model all
policy enforcement goals for traffic.
