AGENDA What is Docker Docker Benefits for Developers Docker on Windows Docker for ASP.NET Developers

WHAT IS DOCKER

Virtual Machines Containers

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.

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

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.

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.

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.

DOCKER BENEFITS FOR DEVELOPERS

AGILITYDevelopers have the freedom to define environments, and the ability to create and deploy apps faster and easier.

CONTROLDevelopers own all the code from infrastructure to app.

PORTABILITYDocker gives you choice without complexity, from a laptop to a team, to private infrastructure and public cloud providers.

CI/CDEnable developers to develop and test applications more quickly and within any environment
