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-ecrCopy 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.
