Today we’ll focus on

Kubernetes OpenShift ManageIQ

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

slide-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

slide-9
SLIDE 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

slide-10
SLIDE 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

slide-11
SLIDE 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

slide-12
SLIDE 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

slide-13

ManageIQ

  • A cloud management platform
  • http://manageiq.org/
  • Botvinnik release - June 2015

a Ruby on Rails project

Alissa Bonas @ Container Con Seattle 2015

slide-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

Creating a provider

  • Kubernetes/OpenShift master host/port
  • SSL
  • Token based

Alissa Bonas @ Container Con Seattle 2015

Inventory

  • Entities
  • Relationships
  • Additional information

Alissa Bonas @ Container Con Seattle 2015

slide-20

Creating more insights

  • Modelling additional entities

as first class citizens

  • Deducing relationships

Cross providers insight

  • Connect all layers of infrastructure, cloud

and containers

  • Currently support cross linking with

○ OpenStack ○ oVirt / RHEV

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

slide-39

Container

  • Traceability - container id, image
  • Restart count - potential issues?

Pods

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

OpenShift Routes

  • Exposes a service by giving it an externally

reachable hostname

  • Can be fine tuned by /path
  • Can be also secured
