Auto Scaling container workloads on Amazon ECS

Preparation

This recipe requires some “prep work” which deploys resources that you’ll build the solution on. You will use the AWS CDK to deploy these resources

In the root of this Chapter’s repo cd to the “606-Autoscaling-Container-Workloads/cdk-AWS-Cookbook-606” directory and follow the subsequent steps:

cd 606-Autoscaling-Container-Workloads/cdk-AWS-Cookbook-606/
test -d .venv || python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt
cdk deploy

Wait for the cdk deploy command to complete.

We created a helper.py script to let you easily create and export environment variables to make subsequent commands easier. Run the script, and copy the output to your terminal to export variables:

python helper.py

Navigate up to the main directory for this recipe (out of the “cdk-AWS-Cookbook-606” directory)

cd ..

Clean up

Delete the container images:

aws ecr batch-delete-image --repository-name aws-cdk/assets \
--image-ids imageTag=$(echo $ECR_IMAGE | cut -d : -f 2)

Go to the cdk-AWS-Cookbook-606 directory:

cd cdk-AWS-Cookbook-606/

To clean up the environment variables, run the helper.py script in this recipe’s cdk- directory with the --unset flag, and copy the output to your terminal to export variables:

python helper.py --unset

Use the AWS CDK to destroy the resources, deactivate your Python virtual environment, and go to the root of the chapter:

cdk destroy && deactivate && rm -r .venv/ && cd ../..

Detach the managed Auto Scaling policy from the IAM role:

aws iam detach-role-policy --role-name AWSCookbook606ECS --policy-arn \
arn:aws:iam::aws:policy/service-role/AmazonEC2ContainerServiceAutoscaleRole

Delete the Auto Scaling IAM role:

aws iam delete-role --role-name AWSCookbook606ECS
