1. Managing Kubernetes and OpenShift with ManageIQ Alissa Bonas @ Container Con Seattle 2015
2. • Containerizing an app The stages of containers world Alissa Bonas @ Container Con Seattle 2015
3. The stages of containers world • Run a container Alissa Bonas @ Container Con Seattle 2015
4. The stages of containers world • Run multiple containers Alissa Bonas @ Container Con Seattle 2015
5. • Orchestrate containers • Run many containers on multiple hosts • Manage a containers environment The stages of containers world Alissa Bonas @ Container Con Seattle 2015
6. Today we’ll focus on Kubernetes OpenShift ManageIQ Alissa Bonas @ Container Con Seattle 2015
7. Kubernetes • Deployment, scaling and orchestration of containers across clusters of hosts. • http://kubernetes.io/ • 1.0 release - July 2015 Developed in Go Alissa Bonas @ Container Con Seattle 2015
8. Kubernetes main concepts • Node - a machine that containers run on • Namespace - partitioning resources created by users into logical groups • Pod - a group of containers Alissa Bonas @ Container Con Seattle 2015
9. Kubernetes main concepts • Replication controller - ensures there are always X replicas of pods • Service - a base load balancer that provides traffic to pods Alissa Bonas @ Container Con Seattle 2015
10. OpenShift • Platform as a service for building and running applications - for developers • http://www.openshift.org/ • 3.0 release - June 2015 Developed in Go Alissa Bonas @ Container Con Seattle 2015
11. OpenShift main concepts • Built on top of Kubernetes • Provides additional capabilities ◦ application lifecycle ◦ routing - extends service ◦ projects - extension of namespaces Build Deploy Run Alissa Bonas @ Container Con Seattle 2015
12. • How many containers exist in my environment? • Does a specific node have enough resources? • How many distinct images are used? • Which registries are used? Insight and control Alissa Bonas @ Container Con Seattle 2015
13. ManageIQ • A cloud management platform • http://manageiq.org/ • Botvinnik release - June 2015 a Ruby on Rails project Alissa Bonas @ Container Con Seattle 2015
14. ManageIQ concepts • “A manager of managers” ◦ supports multiple virtualization providers • Insight and control ◦ inventory overview and events ◦ smart state analysis ◦ workflow/orchestration Alissa Bonas @ Container Con Seattle 2015
15. New in upstream ManageIQ • Providers for container management • Support added for ◦ Kubernetes ◦ OpenShift Alissa Bonas @ Container Con Seattle 2015
16. Working together ManageIQ Kubernetes / Openshift Master Node A Node B Alissa Bonas @ Container Con Seattle 2015
17. Container management providers Alissa Bonas @ Container Con Seattle 2015
18. Creating a provider • Kubernetes/OpenShift master host/port • SSL • Token based Alissa Bonas @ Container Con Seattle 2015
19. Inventory • Entities • Relationships • Additional information Alissa Bonas @ Container Con Seattle 2015
20. Creating more insights • Modelling additional entities as first class citizens • Deducing relationships Alissa Bonas @ Container Con Seattle 2015
21. Kubernetes provider summary page Alissa Bonas @ Container Con Seattle 2015
22. Kubernetes provider relationships Alissa Bonas @ Container Con Seattle 2015
23. OpenShift provider summary page Alissa Bonas @ Container Con Seattle 2015
24. OpenShift provider relationships Alissa Bonas @ Container Con Seattle 2015
25. Projects Alissa Bonas @ Container Con Seattle 2015
26. Nodes • OS and Software versions • How many entities are on a node • Capacity and utilization • Which infrastructure is it running on Alissa Bonas @ Container Con Seattle 2015
27. Node Summary page Alissa Bonas @ Container Con Seattle 2015
28. What do we know about nodes? Capacity Docker and Kubernetes info Alissa Bonas @ Container Con Seattle 2015
29. Nodes • Quick overview on main nodes properties Alissa Bonas @ Container Con Seattle 2015
30. Cross providers insight • Connect all layers of infrastructure, cloud and containers • Currently support cross linking with ◦ OpenStack ◦ oVirt / RHEV Alissa Bonas @ Container Con Seattle 2015
31. Cross linking demystified Virtual Machines Hosts Nodes Pods Containers Storage Network Alissa Bonas @ Container Con Seattle 2015
32. Cross linking demystified Virtual Machines Hosts Nodes Pods Containers Images Storage Network Services Routes Alissa Bonas @ Container Con Seattle 2015
33. Cross provider example - Node Alissa Bonas @ Container Con Seattle 2015
34. Cross provider VM example Alissa Bonas @ Container Con Seattle 2015
35. Nodes capacity and utilization
38. Resource quotas and limit ranges • Limit the number of pods, containers, etc. ◦ tracked per a project/namespace scope • Limit CPU and memory ◦ tracked per pod, container Alissa Bonas @ Container Con Seattle 2015
39. Container • Traceability - container id, image • Restart count - potential issues? Alissa Bonas @ Container Con Seattle 2015
40. Registries Alissa Bonas @ Container Con Seattle 2015
41. Image from a known registry Alissa Bonas @ Container Con Seattle 2015
42. Image from an unknown source Alissa Bonas @ Container Con Seattle 2015
43. Pods • Which containers are part of it • Which services work with it • Which node does it run on • Is it controlled by a replicator? Alissa Bonas @ Container Con Seattle 2015
44. Pods Alissa Bonas @ Container Con Seattle 2015
45. Pod Alissa Bonas @ Container Con Seattle 2015
46. Replicators Searches for pods with this label Alissa Bonas @ Container Con Seattle 2015
47. Services • A portal IP and source/target port pairs • Redirects traffic to relevant pods based on a labels selector Alissa Bonas @ Container Con Seattle 2015
48. Service example Alissa Bonas @ Container Con Seattle 2015
49. OpenShift Routes • Exposes a service by giving it an externally reachable hostname • Can be fine tuned by /path • Can be also secured Alissa Bonas @ Container Con Seattle 2015
50. Events / Timeline • Node ◦ ready / not ready / rebooted • Pod ◦ scheduled • More to come... Alissa Bonas @ Container Con Seattle 2015
51. Tagging • Leveraging ManageIQ tags Alissa Bonas @ Container Con Seattle 2015
52. A glimpse into the future
53. Dashboard - providers overview
54. Dashboard - a single provider view
55. Dashboard of a project
56. • “A picture is worth a thousand words” • Includes cross provider relationships • Statuses Topology Alissa Bonas @ Container Con Seattle 2015
57. Topology demo
58. Topology demo
59. Open source • Rapidly changing projects before their release • Hard to track • A chance to influence early Alissa Bonas @ Container Con Seattle 2015
60. ManageIQ community • http://talk.manageiq.org • https://github.com/ManageIQ/manageiq ◦ Follow label #providers/containers • #manageiq IRC on freenode Alissa Bonas @ Container Con Seattle 2015
