Amazon ECS Exec with AWS CDK

Amazon ECS exec was released with CloudFormation day 1 support. Before we have AWS CDK L2 support, we can simply addPropertyOverride to enable this feature for our cluster and service.

This repository demonstrates how it works in action.

Howto

$ cdk deploy -c use_default_vpc

Write a little helper script(i.e. helper.sh)

# ecs_exec_service CLUSTER SERVICE CONTAINER
function ecs_exec_service() {
  CLUSTER=$1
  SERVICE=$2
  CONTAINER=$3
  TASK=$(aws ecs list-tasks --service-name $SERVICE --cluster $CLUSTER --query 'taskArns[0]' --output text)
  ecs_exec_task $CLUSTER $TASK $CONTAINER
}

# ecs_exec_task CLUSTER TASK CONTAINER
function ecs_exec_task() {
  aws ecs execute-command  \
      --cluster $1 \
      --task $2 \
      --container $3 \
      --command "/bin/bash" \
      --interactive
}

Test it

source helper.sh

ecs_exec_service CLUSTER SERVICE CONTAINER
