Resource Utilization Watch Application [ Observer ]

This project was developed using Python Flask for the backend and React.js for the frontend. You can see the below how to containerize these applications and 3 different hosting and distribution solutions.

1. Docker Compose

Run the applications as a container on the local Docker environment using docker-compose.

Go to Docker-Compose example

2. AWS Fargate - ECS

Run the applications as a container on the AWS Fargate serverless infrastructure using the Elastic Container Service and Elastic Container Registry.

2.1. Create IAM requirements

Create a new IAM [User Group] named "ecs-admin" with the following Permission Policies to manage ECS Fargate Cluster;

Create a new IAM [User] and add it to the newly created as "ecs-admin" [User Group] above to manage the ECS Fargate Cluster.

Note:
Get the Access and Secret Keys generated for this user to access AWS using Terraform and manage the ECS Cluster. Please don't forget to set the keys in the "iac/terraform-ecs/terraform.tfvars/" file.

2.2. Create ECR Private Registry

Create a new Elastic Container Registry(ECR) Private Repository to store application Images

Login to ECR Private Repository in the local Docker using the aws-cli;

aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <account_id>.dkr.ecr.<region>.amazonaws.com

Set the ECR Repository address as a ENV value;

export ECR_REPO="<account_id>.dkr.ecr.<region>.amazonaws.com/<repo_name>"

Build and Push the Image to ECR Private Repository for Python Restapi application;

cd api

docker build -t $ECR_REPO:api-0.0.1 .

docker push $ECR_REPO:api-0.0.1

cd ..

Build and Push the Image to ECR Private Repository for React front-end application;

cd sys-stats

docker build -t $ECR_REPO:client-0.0.1 .

docker push $ECR_REPO:client-0.0.1

cd ..

Build and Push the Image to ECR Private Repository for Nginx proxy server;

cd nginx

docker build --build-arg NGINX_CONF=aws-ecs -t $ECR_REPO:nginx-0.0.1 .

docker push $ECR_REPO:nginx-0.0.1

cd ..

2.3. Create ECS Cluster and Other Resources on the AWS using Terraform

After the creation IAM requirements(Step 1) and ECR Private Repository(Step 2) go to the "iac/terraform-ecs" directory to create Elastic Container Service Cluster and other Services, Components using Terraform;

Go to AWS Fargate - ECS example using Terraform

3. Kubernetes Deployment

Deploy the applications as a container and using Nginx Ingress Controller to Kubernetes.

Go to K8s Deployment example
