Lab 3.4: ECS Fargate Deployment

Skills covered: 3.1.1, 3.1.4, 3.4.5

Mục tiêu

• Build Docker image → push ECR → deploy ECS Fargate

Bước 1: Dockerfile

FROM python:3.12-slim
WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt
COPY . .
EXPOSE 8080
CMD ["python", "app.py"]

Bước 2: Push to ECR

aws ecr create-repository --repository-name my-app
docker build -t my-app .
docker tag my-app:latest {account}.dkr.ecr.{region}.amazonaws.com/my-app:v1
docker push {account}.dkr.ecr.{region}.amazonaws.com/my-app:v1

Bước 3: ECS Setup

• Cluster (Fargate), Task definition (CPU 256, Memory 512), Service (desired: 2, ALB)

Bước 4: Deploy Update

• Build v2 → push → update task definition → update service → rolling update
