The article discusses deploying a Flask Tic-Tac-Toe game on AWS ECS using containers for a modern app deployment journey.Pre-requisites include having Flask, Docker, and AWS CLI installed and configured on your system.The process begins with building the game logic and backend using Flask and setting up the project structure.Frontend design with Tailwind CSS is implemented for the game interface to play the Tic-Tac-Toe game.The game can be run locally by using the 'flask run' command and accessing it via localhost.Containerizing the Flask app involves creating a Dockerfile, building the Docker image, and pushing it to AWS ECR.Deployment on AWS ECS is then executed by creating an ECS cluster, task definition, and service for the app to run live.Accessing the deployed app via the public IP is the final step to see the Flask Tic-Tac-Toe game running on AWS ECS with Fargate.The article concludes with a cleanup section on deleting AWS resources to avoid unexpected charges.Overall, the process involved building, containerizing, deploying, and accessing the Tic-Tac-Toe game on ECS as a complete DevOps deployment cycle.
