1 VMware s (Open Source) Way of Container Dr. Udo Seidel

2 Agenda Introduction The Big Picture Open Source Dimensions Summary

3 Sneak Preview Lots of text/data No demo No I am not working for Vmware VMware competitor No we are not using what is presented

4 Me :-) Teacher of mathematics and physics PhD in experimental physics Started with Linux/Open Source in 1996 With Amadeus since 2006 Before: Linux/UNIX trainer Solution Engineer in HPC and CAx environment Now: Architecture & Technical Governance

5 Introduction

6 Container Working Definition Strong focus on Linux Separation Via Kernel features Of workloads/resources Operations originated view

7 A Bit about VMware Really?!? Part of EMC which is part of DELL EMC Open Source initiatives {code} by DELL EMC Rex-Ray libstorage CoprHD (initally by EMC) Openstack contributions...

8 Why looking at VMware s Containers Why not? Openstack (initial) Photon OS release

9 The Big Picture

10 Legacy No Containers Virtualization of Compute Yes Storage Maybe Network Maybe No real space for Open Source

11 Traditional Container for ESXi Fans vsphere Integrated Containers (VIC) Virtualization of Compute Yes Storage Yes Network Yes Indirectly enforced usage of Open Source

12 VIC Details Virtual Container Host (VCH) Exposes Docker API Holds cache of container images Uses vsphere infrastructure Containers in VMs Interaction vsphere Web Client (via plugin) Native Docker tools

13 VIC Details Source: VMware

14 New Kid Photon Platform Cloud-Native Container-based Open Source First approach with caveats

15 Photon Platform Source: VMware

16 Photon Platform High level Mixture of required compute infrastructure different components/projects Mandatory Optional External Internal Source code on github Licensing see later

17 Open Source Dimensions

18 Sub-Agenda Software Licensing What else?

19 Open Source The Software

20 Container Environment Container Engine Container Host Container Registry... Container Management... Authentication/Authorization Container Security

21 Getting started Photon OS Photon Controller Harbor Lightwave And: ESXi!!

22 st 1 Piece: Photon OS Minimal Linux Optimized for vsphere Works also on KVM Valgrant AWS, GCP,... Docker, Rocket, First release in spring

23 Remember: Photon Platform Source: VMware

24 Photon OS - Details OS-Tree available Versioned filesystem Red Hat Atomic RPM/YUM based Container orchestration Several.. Fleet is still there too :-) See Control plane

25 nd 2 Piece: Photon Controller Control plane Container hosts Load balancer instances Controller instances CLI and Web-based UI First release in autumn

26 Remember: Photon Platform Source: VMware

27 Photon Controller - Details 3 mandatory components Load balancer Controller Lightwave Dedicated VM Installation Meta-management Agent on hypervisor hosts

28 Photon Controller More Details Supports different container orchestration Kubernetes looks preferred Docker Swarm Apache Mesos See also Photon OS CLI binaries for Linux Windows MacOS

29 rd 3 Piece: Lightwave Directory service Authentication Hostname resolution Certificate authority and store

30 Again: Photon Platform Source: VMware

31 Lightwave - Details Background LDAP Heimdal Kerberos DCE/RPC. Installation RPMs available via repo OVA Standalone mode possible

32 th 4 Piece: Harbor Container Registry RBAC via projects Web-based interface Replication Integration with Notary

33 Last Time: Photon Platform Source: VMware

34 Harbor - Details Authentication LDAP MySQL DB Photon OS based NGINX Containerized Stand-alone mode possible

35 Open Source The Software.. Summary

36 Really Last Time: Photon Platform Source: VMware

37 Software Management Missing Full package approach Information on Roll-back Upgrade Mixing closed and Open Source components Reality check Pre-built works best sometimes Self-installed works best sometimes

38 Not covered Container orchestration VMware s way of Kubernetes Something else??

39 Open Source The Licensing

40 General Different licenses involved VMware Usual OpenSource suspects Unclear overall governance

41 Details One license set per project Contains several licenses Depending on used technology Self-check needed Take a read of license of VMware Technology Preview Photon Controller Open Source Pay attention to EULA s too

42 Open Source What else?

43 Less Technical Observations Missing (visibility of) project progress Marketing Tail chasing if at all Docker and Co Kubernetes Openstack

44 Summary

45 Take Aways Promising start in 2015 Missing (visibility of) vision/focus Quite some piecemeal Enterprise grade approach missing Long way to be an commercial alternative
