Docker Setup for Murty Website

This repository includes Docker configuration for both local development and production deployment to AWS ECS, acontainer-based infrastructure system.

Quick Start

Prerequisites

• Docker installed
• Docker Compose installed (usually included with Docker Desktop)

Local Development

Run the development environment with live file watching:

deno task docker-dev

Access the site at http://localhost:8000

The development container:

• Mounts your source code for live editing
• Rebuilds the site when started
• Serves the static site on port 8000
• Persists Deno cache for faster rebuilds

Production Build

Test the production build locally:

deno task docker-prod

Access the site at http://localhost:8080

Docker Commands

Build Images

# Build development image (from project root)
docker build -f docker/Dockerfile --target development -t murty-site:dev .

# Build production image (from project root)
docker build -f docker/Dockerfile --target production -t murty-site:prod .

Run Containers

# Run development container
docker run -p 8000:8000 -v $(pwd):/app murty-site:dev

# Run production container
docker run -p 8000:8000 murty-site:prod

Execute Commands in Container

# Run tests
docker compose -f docker/docker-compose.yaml run dev deno task test

# Lint code
docker compose -f docker/docker-compose.yaml run dev deno task lint

# Build site manually
docker compose -f docker/docker-compose.yaml run dev deno task build

# Access shell
docker compose -f docker/docker-compose.yaml run dev sh

Deployment to AWS ECS

For auto-scaling configuration, see infra/aws-ecs/README.md.

1. Build and Tag for ECR

# Build production image (from project root)
docker build -f docker/Dockerfile --target production -t murty-site:latest .

# Tag for ECR (replace with your AWS account ID and region)
docker tag murty-site:latest <aws-account-id>.dkr.ecr.<region>.amazonaws.com/murty-site:latest

2. Push to ECR

# Login to ECR
aws ecr get-login-password --region <region> | docker login --username AWS --password-stdin <aws-account-id>.dkr.ecr.<region>.amazonaws.com

# Create ECR repository (first time only)
aws ecr create-repository --repository-name murty-site --region <region>

# Push image
docker push <aws-account-id>.dkr.ecr.<region>.amazonaws.com/murty-site:latest

3. Create ECS Task Definition

Create a copy of the sample ECS Task Definitions file:

cp --update=none "infra/aws-ecs/ecs-task-definition.example.json" "infra/aws-ecs/ecs-task-definition.json"

Fill out your AWS credentials in the new Git Ignored file at infra/aws-ecs/ecs-task-definition.json

4. Register Task Definition

aws ecs register-task-definition --cli-input-json file://infra/aws-ecs/ecs-task-definition.json

5. Create/Update ECS Service

# Create service (first time)
aws ecs create-service \
  --cluster <your-cluster-name> \
  --service-name murty-site \
  --task-definition murty-site \
  --desired-count 1 \
  --launch-type FARGATE \
  --network-configuration "awsvpcConfiguration={subnets=[<subnet-id>],securityGroups=[<security-group-id>],assignPublicIp=ENABLED}"

# Update service (for deployments)
aws ecs update-service \
  --cluster <your-cluster-name> \
  --service murty-site \
  --force-new-deployment

Environment Variables

The container uses the environment variables from .env file. In production:

1. Copy config/.env.example to .env and update values
2. For ECS, use task definition environment variables or AWS Secrets Manager

Example for ECS task definition:

"environment": [
  {
    "name": "GOOGLE_ANALYTICS_SITE_CODE",
    "value": "G-XXXXXXXXXX"
  }
]
