Docker Networking:

• Goal: Learn the networking mechanisms in Docker. Understand how to get containers’ IP addresses and how to expose a container service on a specific host port. Learn about linking containers, and how to use nondefault networking configurations. Concepts such as network namespaces, using an OVS bridge, and GRE tunnels are presented to lay a strong foundation for container networking. Finally, learn about more advanced networking setups and tools, such as Weave, Flannel.
• Topics: At the end of this module, you should be able to: Learn about basic concepts that use the default Docker networking configuration, Learn about some Docker commands that let you find the IP addresses of your containers, Establish linking in the containers, Configuring Docker Daemon IP Tables and IP Forward settings, Set up the custom bridge for Docker, Establish connection among the containers from the different host without port mapping.
• Topics: Introduction to Docker Networking, Network Types, Network Namespace, Docker Container Networking, Custom Bridge, Weave Network.
• Hands-on: Finding IP address of the container, Access a service running in a container over the network, Linking Containers in Docker, Configuring Docker Daemon IP Tables and IP Forward settings, Setting up the custom bridge for Docker, Establishing connection among containers from the different host without port mapping.

Docker Configuration and Development:

• Goal: This module covers the configuration of the Docker daemon, especially security settings and remote access to the Docker API. It also covers a few basic problems, like compiling Docker from source, running its test suite, and using a new Docker binary. A few recipes provide better insight on Linux namespaces and their use in containers.
• Objectives: At the end of this module, you should be able to: Learn about the configuration of the Docker daemon, especially security settings and remote access to the Docker API, Discuss few basic problems, like compiling Docker from source, running its test suite, and using a new Docker binary, Finally learn how to change the underlying storage driver that provides a union filesystem to support Docker images.
• Topics: Managing and Configuring Docker Daemon, Compiling Docker Binary from Source, Introduction to enter, Introduction to runs, Secure Remote Access.
• Hands-on: Start, stop, restart and configure Docker Daemon, Build and compile Docker Binary from the source, Run Docker Test suite for Docker Development, Use docker-py to access Docker Daemon Remotely.

Kubernetes:

• Goal: This module introduces you to the new container management platform from Google “Kubernetes”, providing a way to deploy multi-container applications on a distributed cluster. Learn how to deploy Kubernetes on your own infrastructure, starting with a local Vagrant cluster and subsequently on a set of machines started in the cloud. Discuss the key aspects of Kubernetes including pods, services, and replication controllers.
• Objectives: At the end of this module, you should be able to: Learn the basics of Kubernetes and discuss the enhanced capabilities of Kubernetes, Explain the architecture of Kubernetes, Create multi-node Kubernetes cluster with vagrant, Discuss Containers on a Kubernetes Cluster with Pods, Explore the Kubernetes API and run the Dashboard.
• Topics: Kubernetes Architecture, Multimode Kubernetes Cluster with Vagrant, Containers on Kubernetes Cluster with Pods, Running multiple containers in a pod, Dynamic Linking of Containers using Cluster IP service, Kubernetes API, Kubernetes Dashboard, Kubernetes Cluster Authentication.
• Hands-on: Create a multimode Kubernetes Cluster with Vagrant, Starting Containers on a Kubernetes Cluster with Pods, Running multiple containers in a Pod, Using IP services for Dynamic Linking of containers, Configuring authentication to Kubernetes Cluster.

Docker Ecosystem:

• Goal: This module introduces several tools that leverage Docker to ease application deployment, continuous integration, service discovery, and orchestration. As an example, you will find recipes about Docker Compose and Docker Swarm.
• Objectives: At the end of this module, you should be able to: Learn how to use Docker Compose to create a WordPress site, Start containers on a Cluster with Docker Swarm, Manage the containers locally using Kitematic UI and through Docker UI.
• Topics: Introduction to Docker Ecosystem, Docker Compose, Docker Swarm, Managing Containers, Running Containers.
• Hands-on: Using Docker Compose to create a WordPress site, Starting Containers on a Cluster with Docker Swarm, Managing Containers locally using Kitematic UI, Managing Container through Docker UI.

Docker in the Cloud:

• Goal: The Docker daemon can be installed on a developer local machine. However, with cloud computing providing easy access to on-demand servers, it is fair to say that a lot of container-based applications will be deployed in the cloud. This module presents you the recipes to show how to access a Docker host on Amazon AWS. The module also introduces to one of the new cloud services that use Docker: the AWS Elastic Container Service (ECS)
• Objectives: At the end of this module, you should be able to: Learn to deploy various Container based Applications on the Cloud.
• Topics: Accessing Public Cloud to run Docker, Docker Host on AWS EC2, Docker Host on AWS using Docker Machine, EC2 Container Service.
