• VMs as units of scaling

• Hypervisor dependent

• Not easily movable

Docker Containers Overview (DCK)

What is Docker?

• Leading Open-Source Containerization Platform

• Natively Supported in Azure

• Cross-Platform (Win, Linux,…)

• Cross-Platform (Azure, AzureStack, AWS, GCP,…)

Docker Containers - Overview

Docker containers wrap up a piece of

software in a complete filesystem that

contains everything it needs to run: code,

runtime, system tools, system libraries –

anything you can install on a server. This

guarantees that it will always run the same,

regardless of the environment it is running

in

Docker Host

On top of a « Docker » cloud platform:

• Azure Container Instance

• Azure Container Services

• Azure Virtual Machines

• AWS, GCP,…

Where do you run your Docker Container Images?

On top of a « host » Operating System, like:

• Windows 10

• Windows Server 2016/2019

• Linux

• Mac OS

Where do Docker Images come from?

Docker Host• Create your own custom images

• « Layered Cake » of OS and App bits

• Mainly used for storing PRIVATE images

Docker Hub• Hub.docker.com

• Free resource of PUBLIC images

• Option to create PRIVATE images

Docker Hub Docker Host

Running a Docker Container

docker run -i -t ubuntu /bin/bash

Docker CLI command

Run container with interactive terminal Pull "ubuntu"

image from Docker Hub or local registry

Command to execute inside the container

Common Docker CLI operations

docker run - Use an image to run a container

docker pull - Pull an image from a registry

docker build - Build a Docker image

docker exec - Execute a command in a container

docker stop - Stop a running container

docker images - List available Docker images

docker ps - List running Docker containers

DemoCommon Docker CLI Operations

/inetpub/wwwroot/

EXPOSE 80

A Dockerfile is a text document that

contains all the commands a user could

call on the command line to assemble an

image. Using <docker build>, users can

create an automated build that executes

several command-line instructions in

succession.

Building a Docker Image – VS2017

When using Visual Studio 2017 together with

Docker for Windows on the same client, you

get Docker integration features in VS2017…

in Azure

• Pull images from ACR and use it in

different deployment targets:

• Kubernetes | DC/OS | Swarm

• Azure compute solutions

• 3 different SKU’s:

• Basic

• Standard

• Premium

Azure Container Registry (ACR)

Azure Container Registry is a

managed Docker registry

service based on the open-

source Docker Registry 2.0.

Create and maintain Azure

container registries to store

and manage your private

Docker container images.

Azure Container Registry (ACR)

Similar to the public Docker

Hub, but running within an

Azure Subscription,

offering Private images

Azure Container Instance (ACI)

Run Containers directly from Azure Container

Registry:

• Detailed Event Logging

• No additional Orchestration needed

• Integrates with Azure monitoring and

diagnostics capabilities

Azure Container Instances offers the fastest and

simplest way to run a container in Azure, without

having to provision any virtual machines and

without having to adopt a higher-level service.

But what if you need…

• Auto-Scaling

• Rolling Upgrades

• Service Discovery

• Integrated Load-Balancing

• Affinity / anti-affinity

• Scaling Options

• Custom Resource Sizing
