DAY 31- Deploy Containerized Applications with ECS - Day Thirty One

100 days of Cloud on GitHub - Read On iCTPro.co.nz - Read on Dev.to

Get the app

Here Iam using a website with nginx server to deploy on a container with the help of ECR.
Lets get the data

git clone https://github.com/anuvindhs/CLOUD-is-AWSome.git

Docker

Building a docker file

• Lets build our NGINX docker file for our website.

• once you have created the docker file inside the folder, copy-paste the below commands
  

FROM nginx:latestCOPY ./ /usr/share/nginx/html/

• I am using VScode, check below to understand the folder structure
  

  AWS Permissions

• Make sure you have programmatic access via AWS CLI

• Full permissions to ECS & AmazonEC2ContainerRegistryFullAccess

ECR

Create a repository

• Goto ECR from AWS console and create a repository
• Create a ECR repo ,i have named mine webapp-ecr-repo

Login to ECR

if you open the repo, on the right-hand side you can see an option for view push commands.

Now using AWS CLI login to ECR

aws ecr get-login-password --region xx-xxxxxx-xx| docker login --username AWS --password-stdin xxxxxxxxxx.dkr.ecr.xx-xxxxxx-xx.amazonaws.com

Build the docker image

docker build -t webapp-ecr-repo .

Lets tag our image with repo name

docker tag webapp-ecr-repo:latest xxxxxxxxx.dkr.ecr.xx-xxxxxx-xx.amazonaws.com/webapp-ecr-repo:latest

Lets push the image to the repository

docker push xxxxxxxxxx.dkr.ecr.xx-xxxxxxx-xx.amazonaws.com/webapp-ecr-repo:latest

if you are using PowerShell on windows please use windows commands to push the image to the repo.

ECS

Create a cluster

• Goto ECS dashboard and click Create Cluster.

• select EC2 Linux + Networking
  

• Enter Cluster name & EC2 instance type , am keeping it to t2.micro.
  

• Select the default VPC and Subnets available.

• Also enable Auto assign public IP

• you can use default Security group or create a new one or can attach a Security group which is already created.
• Now click Create

Creating Task Definition

• Click on create Task Definition & then select EC2

• I am naming mine as Taskdef-webapp-ecr

• Update Task memory to 128 and Task CPU to 1 vCPU, then click Add Container
  

• Add a name, mine is container-webapp-ecr

• Copy your ECR repo URI from the repository and update that on the image coloumn

• Map your ports, here its 80:80 ,

• Now add, and create the Task definition.
  

Run the Task

• goto Clusters, select Task then click Run New task
  

• Select EC2

• Select out Task Definition we created.

• Select our Cluster

• leave everything default and click Run Task
  

Once the Task is created you will be able to see a Running Status
if you navigate to external Link you will be able to see the live website.

Congratulations, now you have successfully configured a docker image which you have pushed to ECR and Deployed on a container with ECS.
