Configuration of ECS Fargate starts from defining a Task. To define a Task with docker we need to dockerize the code base and need to upload to ECR.

Make Docker image

docker build -t <name> .

Tag the image

docker tag aws-rds-node-api:latest 9999999999999.dkr.ecr.us-east-1.amazonaws.com/aws-rds-node-api:latest

Retrive login passward for he repository

aws ecr get-login-password --region us-east-1 | docker login --username AWS --password-stdin 999999999999.dkr.ecr.us-east-1.amazonaws.com

Push the image to ECR

docker push 9999999999.dkr.ecr.us-east-1.amazonaws.com/aws-rds-node-api:latest

Now the image is ready in the ECR for deployment

Fargate Task Configuration There are two things need to do before start the Task Configuration. There must be Task Role. Other one is define production environment variables.

Create production.env I created S3 bucket to store production.env under the folder cssamlabs/lab-node-atlas-api/.

Then create a Task Execution Role. I added RDSFullAccess since application needs to access RDS.

There must be a policy to access S3 to read productio.env file.

Now start configuring Task Definition

Need to add a container

Copy image name from ECR Port is map to 3040 where NodeJS application configured in Dockerfile.

Configure Production env in Environment Files section by giving the file's ARN

Once create Task Definition is like

Next step is to create Fargate Cluster Configured Cluster is

Create a Container Service A Service Name needed. Select the Cluster created above.

Select the VPC and Subnects. Usually it creates new Security Group.

Load Balancing

Port Configuration

Fargate Service Configured

Now Creating a Task from Task Definition could carryout. Task running in Fargate Service
