Repository for In The Loop demo for CDK - Fargate

Prerequisites

• AWS Account
• AWS CLI (with Credentials)
• Docker
• NPM
• TypeScript (npm -g install typescript)
• dotnet

---

Step 1: Build and Run the .NET Core MVC App

Build:

> dotnet build .\Api.Service.csproj  

Run

> dotnet run .\Api.Service.csproj

---

Step 2: Build and Run the Docker Container

Build an Image of the container

> docker build -t apiservice .

Run an instance of the image

> docker run -d -p 5001:80 --name api apiservice

Login to Bash of the running container

> docker exec -it api /bin/bash

GET http://localhost:5001/api/ping?request=1

Step 3: CDK Stack to build an ECR Repository in AWS

We need to push our Docker Image (apiservice) to ECR in AWS. For that we need to create a repository in ECR. To create the repository, we will use CDK.

• Workshop: http://cdkworkshop.com/

• Api Reference: https://docs.aws.amazon.com/cdk/api/latest/

Install CDK

> npm install -g aws-cdk

Initialize CDK Project

> cdk init -a ecr-stack -l typescript

Compile the Project

> npm run build

List Stacks in the CDK Project

> cdk ls

Install ECR Package

Npm Package: @aws-cdk/aws-ecr

Synthesize CDK to ensure cdk is able to convert code into yaml

> cdk synth EcrRepoStack

Do a DIFF against an environment to see what is the difference b/w local and account.

> cdk diff EcrRepoStack --profile devops

Deploy the stack

> cdk deploy EcrRepoStack --profile devops

---

Step 4: Push Docker Image To ECR

Push the Docker Image to ECR Repository using AWS Credentials

Get a docker Login for ECR

> aws ecr get-login --no-include-email --region ap-southeast-2

User docker to login to AWS-ECR

> docker login -u AWS -p eyJwYXlsb2FkIjoiRjNIWmg4NWovRFdmQmVrR1dJN01....

Build the Image

> docker build -t api-service-repository .

Give the build Image the ECR Tag

> docker tag api-service-repository:latest 19XXXXXXXXX7.dkr.ecr.ap-southeast-2.amazonaws.com/api-service-repository:latest

Push the Tagged Image to ECR

> docker push 19XXXXXXXXX7.dkr.ecr.ap-southeast-2.amazonaws.com/api-service-repository:latest

Step 5: CDK Create a new Stack for Fargate Service and LoadBalancer

Install the Following Package

• @aws-cdk/aws-ecr
• @aws-cdk/aws-ec2
• @aws-cdk/aws-ecs
• @aws-cdk/aws-elasticloadbalancingv2
• @aws-cdk/aws-logs
