1x ALB and TargetGroup should be there. 1x docker file that you can compile and push from local system to AWS ECR.

Step 1. docker logout public.ecr.aws aws ecr get-login-password --region eu-west-1 --profile AWS_PROFILE | docker login --username AWS --password-stdin AWS_ACCT_ID.dkr.ecr.eu-west-1.amazonaws.com/base-repo

Step 2. aws ecr create-repository --repository-name base-repo --image-tag-mutability IMMUTABLE docker build -t base-repo .

docker tag base-repo:latest AWS_ACCT_ID.dkr.ecr.eu-west-1.amazonaws.com/base-repo:latest docker push AWS_ACCT_ID.dkr.ecr.eu-west-1.amazonaws.com/base-repo:latest

Step 3. aws ecs register-task-definition --cli-input-json file://TaskDefinition.json --region eu-west-1 --query 'taskDefinition.taskDefinitionArn' --profile citrus_lab

aws ecs create-cluster --cluster-name base-repo --region eu-west-1 --profile AWS_PROFILE

aws ecs create-service --cli-input-json file://service.json --region eu-west-1 --profile AWS_PROFILE

Step 4. Add autoscaling: aws application-autoscaling register-scalable-target --resource-id service/base-repo/base-repo --service-namespace ecs --scalable-dimension ecs:service:DesiredCount --min-capacity 1 --max-capacity 20 --role-arn arn:aws:iam::AWS_ACCT_ID:role/ecsServiceAutoScalingrole --region eu-west-1 --profile AWS_PROFILE

aws application-autoscaling put-scaling-policy --cli-input-json file://scale-out.json --region eu-west-1 --profile AWS_PROFILE

Step 5. Store alb url in a variable and put the load for simulation.

while true; do curl -so /dev/null $alb_url ; sleep 1 ; done &

while true; do ab -l -c 9 -t 1200 curl -so /dev/null $alb_url ; sleep 1 ; done &

ab = apache bench load
