Features of Docker

• Docker has the ability to reduce the size of
  development by providing a smaller footprint of
  the operating system via containers.
•  
• With containers, it becomes easier for teams
  across different units, such as development, QA
  and Operations to work seamlessly across
  applications.
•  
• You can deploy Docker containers anywhere, on any
  physical and virtual machines and even on the
  cloud.
•  
• Since Docker containers are pretty lightweight,
  they are very easily scalable.

Docker Overview

Components of Docker

• Docker has the following components
• Docker for Mac - It allows one to run Docker
  containers on the Mac OS.
• Docker for Linux - It allows one to run Docker
  containers on the Linux OS.
• Docker for Windows - It allows one to run Docker
  containers on the Windows OS.
• Docker Engine - It is used for building Docker
  images and creating Docker containers.
• Docker Hub - This is the registry which is used
  to host various Docker images.
• Docker Compose - This is used to define
  applications using multiple Docker containers.

INTEGRATING KUBERNETES WITH DOCKER

Docker - Kubernetes Architecture

• Kubernetes is an orchestration framework for
  Docker containers which helps expose containers
  as services to the outside world. For example,
  you can have two services - One service would
  contain nginx and mongoDB, and another service
  would contain nginx and redis. Each service can
  have an IP or service point which can be
  connected by other applications. Kubernetes is
  then used to manage these services.

7
Kubernetes has several components in its
architecture

• etcd - This component is a highly
  available key-value store that is used for
  storing shared configuration and service
  discovery. Here the various applications will be
  able to connect to the services via the discovery
  service.
• Flannel - This is a backend network which is
  required for the containers.
• kube- apiserver - This is an API which can be
  used to orchestrate the Docker containers.

8

• kube-controller-manager - This is used to control
  the Kubernetes services.
• kube-scheduler - This is used to schedule the
  containers on hosts.
• Kubelet - This is used to control the launching
  of containers via manifest files.
• kube-proxy - This is used to provide network
  proxy services to the outside world.
