Learn to deploy Python Flask App using Docker, AWS ECS and AWS Fargate.

Deploy Python App using ECS Fargate

→ Use Docker to Deploy Flask App

• Clone this project
• Move to project directory
• Run this to build the image:

docker build -t flask-demo-app .

• Now we need to run the container from image. Run this command:

docker run -it -p 5000:5000 flask-demo-app:latest

• You should be able to open the flask app in browser using:

http://localhost:5000

→ Use ECS Fargate to Deploy Flask App

• Create Repository in Elastic Container Registry (ECR):

aws ecr create-repository --repository-name demo-flask-app

• Get a command you can use for logging in to the ECR repository you’ve just created:

aws ecr get-login --region $YOUR_REGION --no-include-email

• Let's put our local docker image to ECR (ACCOUNTID is your account id and REGIONNAME is your region):

docker tag flask-demo-app:latest ACCOUNTID.dkr.ecr.REGIONNAME.amazonaws.com

• Go to ECS. Create cluster and click on get started

• Write container name and give the link to the docker image and you uploaded in the preivous steps. You should be able to get it from ECR as well.

• Click on next

• Make sure the service has ecsContainerRole Click on next

• Click on next

• Finally, Review and create the cluster

💯 Yay! You'll see the success message
