No Parachute Introduction into Unikernel Orchestration

This set of slides gives a gentle introduction into running unikernels and implications thereof, especially on macs. The talk is intended to encourage new tooling/development in the ecosystem targeted towards those who might not be familiar with vms or hypervisors.

1. A No Parachute Introduction to Unikernel Orchestration
2. Teach Tool Grow
3. github.com/ deferpanic/ virgo By the end of the talk attendees should feel comfortable in writing tools to interact with unikernels like testing/ system administration/ volume manipulation and more.
4. NO
5. Talking orchestration - not compiling - that's it's own little ball of shit.
6. Progrommatic Hypervisor Usage
7. debugging networking volume manipulation higher level service orchestration why
8. Just use qemu!
9. dev test staging production automated repeatable fast painless
10. hypervisors qemu/kvm virtualbox xhyve
11. manageability
13. higher level orchestration
14. service discovery
15. load balancing
16. resource aware scheduling 8 cores 32G 4 cores 16G 2 cores 8G
17. deploying
19. fail-over
21. "kernels" multiboot or disk image
22. egrep '(vmx|svm)' /proc/ cpuinfo
23. hypervisor situation on osx
25. L2 —> L7
26. networking
27. There’s no place like 127.0.0.1 host only
29. nat
30. ip forwarding
31. http://downloads.sourceforge.net/ tuntaposx/tuntap_20150118.tar.gz sudo kextstat | grep tap tuntap
32. pfctl nat on en0 from $1:network to any -> (en0)
33. network isolation
34. routing root@host:/# arp -a ? (10.0.84.32) at 52:54:00:e0:af:dc [ether] on br5 ? (172.16.1.4) at 00:22:19:5a:34:87 [ether] on eno2 ? (172.16.1.2) at 14:fe:b5:d1:a0:c1 [ether] on eno2 ?
