The document discusses containers as tools for DevOps that enable better security and management of applications, promoting a microservice architecture for flexible deployments. It outlines fundamental knowledge for managing Windows server containers using Docker on Windows 10, including installation and creation processes. Key concepts covered include Docker's integration, the advantages of containers, and the differences between traditional and modern DevOps practices.

What is a container?

Isolation Scale
Higher Cost
More Management
Lower Cost
Less Management

4. Container Security
“Containers offer many overall
advantages. From a security
perspective, they create a method
to reduce attack surfaces and
isolate applications to only the
required components, interfaces,
libraries and network connections.”
– Aaron Grattafiori, NCC Group

6. What Problem(s) is Docker Trying to Solve?
 Enable DevOps
 The synthesis of operations and development working together
through the entire service lifecycle, from design through the
development process to production support.
 Support for Microservice Architecture (MSA)
 MSA is an approach to developing a single application as a suite of
small services, each running in its own process and communicating
with lightweight mechanisms, often an HTTP resource API.
 These services are built around business capabilities and
independently deployable by fully automated deployment
machinery.
 There is a bare minimum of centralized management of these
services, which may be written in different programming languages
and use different data storage technologies.

In this lab, you will gain fundamental knowledge for managing Windows Server containers on Windows 10 by
using Docker commands. You will learn how to:
1.Install the pre-requisites for Docker on Windows 10.
2.Install Docker.
3.Install a Nano Server base image that is used to create containers.
4.Create containers with and without Hyper-V isolation.
5.Create layered container images from containers.
6.Remove Windows Server containers and Windows Server container images by using Docker.
You will also learn about the parent-child relationship between containers and between container images.
Finally, you will learn how to deploy a Nano Server package and install the Web server role in a container.

Containers

10. @ITProGuru
• Windows Containers run
Windows processes in a
container while sharing
the kernel space with the
underlying operating
system.
• Hyper-V containers wrap
a Hyper-V layer around
the container, then run
Windows processes within
the Hyper-V container.

15. Docker Tools
 Docker Machine – Utility to provision Docker Hosts
 Docker Engine – The server side component responsible
for running and maintaining containers on a Docker Host.
 Docker Build – Create images using Dockerfiles
 Docker Run – Run instances of images as containers
 Docker Client – the client side tool for interacting with the
Docker Engine.
 Docker Compose – Orchestrates complex application with
multiple containers.
 Docker Hub – The Docker maintained repository for public
and private images. https://hub.docker.com/
 Docker Swarm – Clusters Docker Engines across multiple
hosts.
 Docker Datacenter – on premises managed container
solution

16. The Dockerfile
Instruction Description
FROM The source container to create from
ENV Set environmental variables for the image that are carried to the container
COPY Copies files and directories into the image from client
ADD Copies files and directories into the image from client
EXPOSE Tells Docker to expose a network port from the container
RUN Run a command in the image
CMD The command run when a container starts (One per Dockerfile)
ARG Arguments set when an image is built
ENTRYPOINT Allows a container to be run like an executable
WORKDIR Sets the working directory for COPY, ADD, RUN, CMD, and ENTRYPOINT
VOLUME Sets up a mountable volume inside a container
