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.
Let’s 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:latest
COPY ./ /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.
