1 Managing Kubernetes and OpenShift with ManageIQ Alissa Bonas, Dublin 2015

2 The stages of containers world

3 Containerizing an app

4 Run a container

5 Run multiple containers

6 Run multiple containers Orchestrate containers Run many containers on multiple hosts Manage a containers based environment

7 Today we ll focus on Kubernetes OpenShift ManageIQ

8 Kubernetes Deployment, scaling and orchestration of containers across clusters of hosts. 1.0 release - July 2015 Developed in Go

9 Kubernetes concepts Node - a machine that containers run on Pod - a group of containers Replication controller - ensures there are always X replicas of pods

10 Kubernetes concepts Service - a base load balancer that provides traffic to pods Namespace - partitioning resources created by users into logical groups

11 OpenShift Platform as a service for building and running applications - for developers Built on top of Kubernetes Developed in Go 3.0 release - June 2015

12 OpenShift concepts Provides additional capabilities application lifecycle routing - extends service projects - extension of namespaces Build Deploy Run

13 Insight and control How many containers exist in my environment? Does a specific node have enough resources? How many distinct images are used? Which registries are used?

14 ManageIQ A cloud management platform supports multiple virtualization providers Insight and control a Ruby on Rails project inventory overview and events smart state analysis workflow/orchestration

15 New in upstream ManageIQ Providers for container management Supported providers Kubernetes OpenShift

16 Container management providers

17 Working together Kubernetes / Openshift Node A ManageIQ REST Master Node B

18 Inventory Entities Relationships Additional information

19 Creating more insights Modelling additional entities as first class citizens Deducing relationships

20 Kubernetes provider summary

21 Kubernetes provider relationships

22 OpenShift provider summary

23 OpenShift provider relationships

24 Nodes OS and Software versions How many entities are on a node Capacity and utilization Which infrastructure is it running on

25 Node summary page

26 What do we know about nodes? Capacity Docker and Kubernetes info OS info

27 What do we know about nodes?

28 Cross providers insight Connect all layers of infrastructure, cloud and containers Currently supports cross linking with OpenStack ovirt / RHEV VMware vcenter

29 Cross linking demystified Nodes Virtual Machines Pods Containers Hosts

30 Cross linking zoom out Routes Services Images Nodes Pods Containers Virtual Machines Storage Hosts Network

31 Cross provider example - Node

32 Cross provider - VM side

33 Nodes capacity and utilization

34

35

36 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

37 Container Traceability - node, container id, image

38 Image from a known registry

39 Image from an unknown source

40 Registries

41 Pods Which containers are part of it Which services work with it Which node does it run on Is it controlled by a replicator?

42 Pod

43 Replicators Searches for pods with this label

44 Services A portal IP and source/target port pairs Redirects traffic to relevant pods based on a labels selector

45 Service example

46 OpenShift Routes Exposes a service by giving it an externally reachable hostname Can be fine tuned by /path Can be also secured

47 Events / Timeline Node ready / not ready / rebooted Pod scheduled More to come...

48 Tagging Leveraging ManageIQ tags

49 Topology view A picture is worth a thousand words Includes cross provider relationships Status color indication

50 Topology live demo

51 A glimpse into the future

52 Dashboard - providers overview

53 Dashboard - a single provider view

54 Dashboard of a project

55 Smart State Analysis Inspect the packages included in an image Combined with vulnerabilities db, generate alerts for important security issues on running containers

56 Analysis of an image

57 An image after analysis

58 ManageIQ community Follow label #providers/containers #manageiq IRC on freenode
