The document discusses Docker and how it can benefit .NET developers. It begins with an introduction of the presenter and their background. It then outlines the agenda which includes explaining what Docker is, benefits of Docker for developers, using Docker on Windows, and how Docker can be used for ASP.NET development. The document proceeds to explain key Docker concepts such as images, containers, and layers. It also discusses how Docker can provide benefits like write once deploy anywhere, agility, control, portability, and enabling continuous integration and continuous delivery workflows. Lastly it covers using Docker with .NET on Windows and tools for developing and debugging ASP.NET applications in Docker containers.

5. WHAT IS DOCKER…
Virtual Machines Containers
http://www.docker.com/what-docker

6. WHAT IS DOCKER…
Docker Engine
https://docs.docker.com/engine/understanding-docker/
 is a client-server application
 with these major components:
 A server which is a type of long-running
program called a daemon process.
 A REST API which specifies interfaces
that programs can use to talk to the
daemon and instruct it what to do.
 A command line interface (CLI) client.

7. WHAT IS DOCKER…
Docker’s architecture When you run a container
 $ docker run -i -t ubuntu /bin/bash
 Docker Engine does the following:
 Pulls the ubuntu image
 Creates a new container
 Allocates a filesystem and mounts a
read-write layer
 Allocates a network / bridge interface
 Sets up an IP address
 Executes a process that you specify
 Captures and provides application
output

9. WHAT IS DOCKER…
Images and layers
 Each Docker image references a list of
read-only layers that represent
filesystem differences.
 Layers are stacked on top of each
other to form a base for a container’s
root filesystem.

10. WHAT IS DOCKER…
Build your own images

11. WHAT IS DOCKER…
Updating and committing an image Building an image from a Dockerfile

Container and layers

14. WHAT IS DOCKER…
Container and layers

15. WHAT IS DOCKER…
Data volumes and the storage driver
 When a container is deleted, any data
written to the container that is not
stored in a data volume is deleted
along with the container.
 A data volume is a directory or file in
the Docker host’s filesystem that is
mounted directly into a container.
 Reads and writes to data volumes
bypass the storage driver and operate
at native host speeds.

16. DOCKER BENEFITS FOR DEVELOPERS
 Write once, deploy anywhere
 Docker is a platform for
developers and sysadmins to
develop, ship, and run
applications.
 Docker lets you quickly assemble
applications from components
and eliminates the friction that
can come when shipping code.
 Docker lets you get your code
tested and deployed into
production as fast as possible.

17. DOCKER BENEFITS FOR DEVELOPERS
AGILITY
Developers have the freedom to define environments, and the ability to create and deploy apps faster and easier.
CONTROL
Developers own all the code from infrastructure to app.
PORTABILITY
Docker gives you choice without complexity, from a laptop to a team, to private infrastructure and public cloud providers.
CI/CD
Enable developers to develop and test applications more quickly and within any environment
