What is Kubernetes
Kubernetes is an open source container orchestration platform developed by Google for managing microservices or containerized applications across a distributed cluster of nodes. Kubernetes is highly resilient and supports zero downtime, rollback, scaling, and self-healing of containers. The main objective of Kubernetes is to hide the complexity of managing a fleet of containers. It can run on bare metal machines or on public or private cloud platforms such as AWS, Azure and OpenStack. Kubernetes follows a client-server architecture.
Main Components of the Kubernetes Master Server
- etcd cluster - a distributed key value storage that stores Kubernetes cluster data
kube-apiserver -the central management entity that receives all REST requests for modifications to cluster elements
- kube-controller-manager - runs controller processes like replication controller (sets number of replicas in a pod) and endpoints controller (populates services, pods and other objects)
- cloud-controller-manager -responsible for managing controller processes with dependencies on the underlying cloud provider
kube-scheduler - helps schedule the pods (a co-located group of containers inside which our application processes are running) on the cluster nodes based on resource utilization
Main components of the Kubernetes Node (Worker) Server
- kubelet - the main service on a node, taking in new or modified pod specifications from kube-apiserver, and ensuring that pods and containers are healthy and running
- kube-proxy - runs on each worker node to deal with individual host subnetting and expose services
kubectl is a command line tool that interacts with kube-apiserver and send commands to the master node. Each command is converted into an API call.

AWS re:Invent 2017: Mastering Kubernetes on AWS (CON308)
A lot of progress has been made on how to bootstrap a cluster since Kubernetes' first commit and is now only a matter of minutes to go from zero to a running cluster on Amazon Web Services. However, evolving a simple Kubernetes architecture to be ready for production in a large enterprise can quickly become overwhelming with options for configuration and customization.
In this video, Arun Gupta, open source strategist for AWS and Raffaele Di Fazio, software engineer at Zalando, show common practices for running Kubernetes on AWS and share insights from experience in operating tens of Kubernetes clusters in production on AWS.

Kubernetes Helm: Why It Matters
Kubernetes Helm makes application deployment easy, standardized and reusable. Use of Kubernetes Helm leads to better developer productivity, reduced Kubernetes deployment complexity and enhanced enterprise production readiness. Enterprises using Kubernetes Helm can speed up the adoption of cloud native applications. These applications can be sourced from open-source community provided repositories, or from an organization's internal repository of customized application blueprints.
Roopak Parikh Co-Founder and CTO of Platform9, talks about why Kubernetes Helm makes application deployment easy, standardized and reusable and why the use of Kubernetes Helm leads to better developer productivity, reduced Kubernetes deployment complexity and enhanced enterprise production readiness.

Securing Cluster Networking with Network Policies - Ahmet Balkan, Google
Securing Cluster Networking with Network Policies - Ahmet Balkan, Google In a secure microservices cluster, you should only have the pods that need to communicate with each other to be able to establish network connections, and block all others. But how? Until recently, Kubernetes users could not enforce policies for container networking.
Covers use cases for network policies, the Network Policy API, how to configure network policies, and how the configured policies are enforced. Also covers other methods to secure applications at network and application layers, and how Network Policies relate to service mesh projects such as Istio.
