Take container cluster management to the next level learn how to administer and configure
Kubernetes on CoreOS and apply suitable management design patterns such as Configmaps
Autoscaling elastic resource usage and high availability. Some of the other features
discussed are logging scheduling rolling updates volumes service types and multiple cloud
provider zones. The atomic unit of modular container service in Kubernetes is a Pod which is a
group of containers with a common filesystem and networking. The Kubernetes Pod abstraction
enables design patterns for containerized applications similar to object-oriented design
patterns. Containers provide some of the same benefits as software objects such as modularity
or packaging abstraction and reuse. CoreOS Linux is used in the majority of the chapters and
other platforms discussed are CentOS with OpenShift Debian 8 (jessie) on AWS and Debian 7 for
Google Container Engine. CoreOS is the main focus becayse Docker is pre-installed on CoreOS
out-of-the-box. CoreOS: Supports most cloud providers (including Amazon AWS EC2 and Google
Cloud Platform) and virtualization platforms (such as VMWare and VirtualBox) Provides
Cloud-Config for declaratively configuring for OS items such as network configuration (flannel)
storage (etcd) and user accounts Provides a production-level infrastructure for containerized
applications including automation security and scalability Leads the drive for container
industry standards and founded appc Provides the most advanced container registry Quay Docker
was made available as open source in March 2013 and has become the most commonly used
containerization platform. Kubernetes was open-sourced in June 2014 and has become the most
widely used container cluster manager. The first stable version of CoreOS Linux was made
available in July 2014 and since has become one of the most commonly used operating system for
containers. What You'll Learn Use Kubernetes with Docker Create a Kubernetes cluster on CoreOS
on AWS Apply cluster management design patterns Use multiple cloud provider zones Work with
Kubernetes and tools like Ansible Discover the Kubernetes-based PaaS platform OpenShift Create
a high availability website Build a high availability Kubernetes master cluster Use volumes
configmaps services autoscaling and rolling updates Manage compute resources Configure
logging and scheduling Who This Book Is For Linux admins CoreOS admins application developers
and container as a service (CAAS) developers. Some pre-requisite knowledge of Linux and Docker
is required. Introductory knowledge of Kubernetes is required such as creating a cluster
creating a Pod creating a service and creating and scaling a replication controller. For
introductory Docker and Kubernetes information refer to Pro Docker (Apress) and Kubernetes
Microservices with Docker (Apress). Some pre-requisite knowledge about using Amazon Web
Services (AWS) EC2 CloudFormation and VPC is also required.
