Container benefits

•

Portable runtime application environment

•

Package application and dependencies in a single artifact

•

Run different application versions (dev/test/prod, different dependencies) simultaneously

•

Faster development and deployment cycles

•

Better resource utilization

(8)

(9)

Docker containerization

•

Docker – Lightweight container virtualization platform

•

Provides tools to manage and deploy your applications

•

Over 80% of containers in 2018 run on Docker

•

Simplifies creation/management/operation of containers

•

Built by Docker, Inc.

•

Licensed under the Apache 2.0 license

(10)

Docker image

•

Read-only (immutable) base

•

Docker images built from base image, instructions to add layers on top

•

Union file systems to combine different layers into a single image

•

Used to launch container

•

Instructions stored in Dockerfile

^bootfs

kernel Base image

Image Image Container

References parent image Image

Creating Docker container

Dockerfile

FROM microsoft/dotnet:2.1-sdk-nanoserver-sac2016 AS build WORKDIR /src

COPY QuizUi/QuizUi.csproj QuizUi/

COPY WebApiLib/WebApiClient.csproj WebApiLib/

COPY QuizApiModels/QuizApiModels.csproj QuizApiModels/

COPY . .

WORKDIR /src/QuizUi

RUN dotnet publish QuizUi.csproj -c Release -o /app

FROM microsoft/dotnet:2.1-aspnetcore-runtime-nanoserver-sac2016 AS final WORKDIR /app

COPY --from=build /app . EXPOSE 80

ENTRYPOINT ["dotnet", "QuizUi.dll"]

Docker workflow

•

Pull base image from repository (e.g., Docker Hub)

•

Build an image from a Dockerfile

•

Inspect a container

•

Attach a volume to a container

•

Run a container

Why containers for .NET apps?

Better resource utilization

Deployment/

runtime consistency

Scaling

Fully managed

• Tight integration with Amazon EC

• Integration with Docker toolset

• AWS Management Console and AWS CLI

Highly available

• Amazon S3 backed

• Regional endpoints

Secure

• AWS Identity and Access Management (IAM) resource- based policies

• AWS CloudTrail audit logs

• Images encrypted at transit and at rest

Amazon ECS

•

Fully managed elastic service

•

Shared-state optimistic scheduling

•

Deep integration with other AWS services

Amazon Elastic Container Service (Amazon ECS) is a highly scalable, high-performance container

orchestration service that supports

Docker containers and allows you

to run and scale containerized

applications on AWS

Amazon ECS: AWS Fargate

AWS Fargate is a technology that you can use with Amazon ECS to run

containers without having to manage servers or clusters of Amazon EC2

instances. With AWS Fargate, you no longer have to provision, configure,

or scale clusters of virtual machines to run containers.
