The container revolution

Click to edit



• Massive growth of cloud native applications Microservices architectures

• Containers are a key componentof cloud native applications• Application level software delivery• Lightweight (higher density vs VMs)• Faster start-up time (vs VMs)

• Most users still overwhelmingly consume VM’s

• Market is fast moving and unsettled• What do I pick for CaaS?

• Focus from most vendors is on enterprise use• Multi-tenancy is an afterthought

The challenges for service providers

• Consumers of IaaS are demanding a container platform

• They want it in the same place

• IaaS is currently a VM based business

• What should the cloud service provider sell ?• Containers vs Virtual Machines?

• How should multi-tenancy be handled?

• Should the VM be removed ? How ?

• How can I orchestrate all of this ?• Lots of emerging offerings focused on

the Enterprise market only

We couldn’t find the answer so we went and built that s**t

CloudStack Container Service

• Based on the model offered by Google and AWS• CaaS offering within existing IaaS environments

• No disruption to user experience or business

• Users deploy and orchestrate containers within their IaaS infrastructure

• Users pay for the underlying VM’s / infra.

• Built on established technologies

• Apache CloudStack

• Kubernetes

• CoreOS

CloudStack Container Service – what is it

• UI/API Plugin functionality for Cloudstack

• Orchestrates the deployment of Kubernetes within VM clusters to manage containers

• Creates secure access to theKubernetes endpoint and dashboard

• Allows pass-through access to VMs

• Acts as a control plane

C l o u d s t a c k c o n t a i n e r s e r v i c e



Components




1. Framework adds the concept of a group or cluster of VMs into CloudStack and enables the creation and management of those VMs as a group at the API level.

2. Deploy Kubernetes onto a group of VMs, configure them as a Kubernetes cluster and query the Kubernetes API to obtain and return state information.

3. UI to simplify interaction with the clusters once created.

Demonstration







• Created a Container Cluster

• Used the auto-deployed dashboard

• Deployed two HA containerised applications

• Created firewall and load-balancing rules to expose those

applications

• Accessed those applications

Summary

name : name of the cluster

description

zoneId: zone in which cluster to be launched. zone to be of 'advanced' zone

networkId: network of 'shared' type

nodeCount: number of node instances in the cluster used for launching the containers

serviceOfferingId: uuid of the computer offering that shall be used for launching nodes, and master k8s VMs

templateId: UUID of the template for creating the VMs

Technology Choices

• Apache CloudStack

• IaaS orchestration platform

• Drives many of the world’s largest public clouds

• Tightly defined scope

• Kubernetes

• Kubernetes is an open-source system for automating deployment, operations, and scaling of containerised applications

• Open sourced by Google now at the CNCF under the Linux Foundation

• Set to become defacto. In use at Google,GKE, HP Helion, RedhatOpenshift, VMware Cloud, Windows Azure

Agnostic

• Uses Docker engine by default but can choose rkt by CoreOS• Users can choose the container networking solution they want, the

current default is flannel

Agnostic

• Currently implemented K8S, but framework can be used for other cluster based platforms in the future:

Network Storage Compute

A g n o s t i c




• Automate exposing services to public internet

• Support resizing of clusters

• Auto-scaling of clusters

• Upgrade of Kubernetes version

• Intelligent independent sizing of master node

• Optional HA for master nodes.

• Use of distributed etcd data store

• Optional use of anti-affinity groups

• Support for CloudStack volumes in Kubernetes for data persistency

• Support for baremetal deployments.

F e a t u r e r o a d m a p




• Licensed version at GA July 2016

• Currently supported in Apache Cloudstack >4.5

• and today…….
