AWS ECS Express Deployment Assistant

STEP 1

Accelerates containerized app deployment to AWS ECS Express by automating Docker builds, ECR setup, and IAM configuration so startups deploy applications in minutes while maintaining best practices.

How to use the AWS ECS Express Deployment Assistant AI Prompt

Overview: This template automates the entire deployment pipeline for containerized applications onto AWS ECS Express. It systematically guides the user through Docker image building, ECR repository creation and pushing, detailed IAM role configuration (execution, infrastructure, and task roles based on best practices), and the final ECS service deployment, ensuring all networking and resource allocations are correctly configured.

Who is this for: DevOps Engineers, Startup CTOs/Founders, and Cloud Infrastructure Architects.

How it works: The Assistant first collects essential project details (path, region, ports). It then meticulously handles the complex IAM setup by referencing official AWS documentation for Express service roles and intelligently prompts the user for existing ARNs or generates new roles based on required permissions (including analyzing the project folder for necessary API calls if a task role ARN isn't provided). Finally, it executes the `aws ecs create-express-gateway-service` command with all collected parameters and provides the resulting application URL.

Pro-Tip: For the Task Role ARN generation step, provide the AI with a list of external services your application interacts with (e.g., DynamoDB, S3) in the Environment Variables section, even if you don't provide a specific ARN. This allows the AI to generate a more accurate and comprehensive IAM policy, minimizing post-deployment permission errors.

Original Prompt Template

AWS ECS Express Deployment Assistant Task Deploy your containerized application to AWS ECS Express with automated setup of ECR, IAM roles, and service configuration. You will assist and guide me through building my Docker image, pushing to ECR, and deploying to ECS Express with proper IAM permissions. Prerequisites: Before starting, ensure you have: AWS CLI installed and configured with appropriate credentials Docker, Finch, or another container build tool installed A Dockerfile in your project directory aws-cli with permissions to create ECR repositories, IAM roles, and ECS services Required Information Please provide the following details about your deployment: Project Configuration Project Folder Path: [Full path to your project directory containing Dockerfile] AWS Region: [e.g., us-east-1, us-west-2, eu-west-1, ap-southeast-1] Container Port: [Port your application listens on - default: 80] ECR Repository Configuration ECR Repository Name: Use folder name as repository name (default) or specify custom name IAM Role Configuration 3.1 Please ask the user if they want to create a task execution role or give an existing iam role arn instead. In case the user ask to create it please create the iam role according to the details in this aws documentation web page https://docs.aws.amazon.com/AmazonECS/latest/developerguide/express-service-getting-started.html 3.2 Please ask the user if they want to create a task infrastructure role or give an existing iam role arn instead. In case the user ask to create it please create the iam role according to the details in this aws documentation web page https://docs.aws.amazon.com/AmazonECS/latest/developerguide/express-service-getting-started.html 3.3 Please ask the user for task role arn. The user can provide iam role arn or you can scan the folder with all files and generate the required iam permissions that are required. Make sure not to miss any required permission and find all api calls that required permissions. Then, generate an iam role with the require permission. Make the ECS allow inbound connection from the load balancer on port 443 to the ECS container port Additional Configuration (Optional) Environment Variables: [KEY=VALUE pairs, comma-separated]Memory Allocation: [e.g., 512, 1024, 2048 MB - default: 2048] CPU Allocation: [e.g., 256, 512, 1024 - default: 1024] Health Check Path: [e.g., /health, /api/health - default: /] Instructions: Once you provide the information above, I will: Analyze Your Setup Ask for the folder with your docker file, and validate Dockerfile exists in specified folder Build the docker image with Intel architecture and push it to ECR Create the IAM roles Deploy to ECS Express using this command: aws ecs create-express-gateway-service --execution-role-arn arn:aws:iam::[ACCOUNT_ID]:role/[IAM_ROLE] --infrastructure-role-arn arn:aws:iam::[ACCOUNT_ID]:role/[IAM_ROLE] --task-role-arn arn:aws:iam::[ACCOUNT_ID]:role/[IAM_ROLE] --primary-container image=<ecr image>,containerPort=<port> Pay attention for other parameters if there were requested and use them as well After running this command please get and print the application URL to the screen and let the user know they need to wait 5-10 minutes until the service is fully deployed.
