Ladislav Prskavec is presenting on AWS Elastic Container Service (ECS). ECS is a highly scalable container management service that supports Docker containers and allows running applications on a managed cluster of EC2 instances without needing to install and manage your own cluster infrastructure. The key components of ECS include clusters, container instances, task definitions, schedulers, services, and tasks. Ladislav provides examples of using the AWS CLI to create an ECS cluster, run EC2 instances as container instances, define a task, create a service, and list/describe services.

3. AWS ECS
• Amazon EC2 Container Service (ECS) is a highly
scalable, high performance container
management service that supports Docker
containers and allows you to easily run
applications on a managed cluster of Amazon
EC2 instances. Amazon ECS eliminates the
need for you to install, operate, and scale your
own cluster management infrastructure.
• Pricing: free (pay for EBS, EC2, ELB)

7. Create Cluster
$ aws ecs create-cluster
--cluster-name meetup-demo

8. Run Instances
$ aws ecs run-instances
--image-id ami-d0b9acb8
--count 1
--instance-type t2.small
--key-name mykeys
--security-group-ids sg-91d1f1ff
--iam-instance-profile
Name=ecsInstanceRole
--subnet-id subnet-61f1cffd
--user-data file://cluster_setup

9. Cluster setup file
$ cat cluster_setup
#!/bin/bash
yum install -y aws-cli
aws s3 cp s3://my-ecs-config/ecs.config
/etc/ecs/ecs.config
echo ECS_CLUSTER=meetup-demo >> /etc/
ecs/ecs.config

10. List instances
$ aws ecs list-container-instances
--cluster meetup-demo

11. List task definitions
$ aws ecs list-task-definitions
Register new task
$ aws ecs register-task-definition
--cli-input-json file://task.json

12. Create service
$ aws ecs create-service
--service-name our-demo
--task-definition hello_meetup:1
--desired-count 1
--cluster meetup-demo

13. List running services
$ aws ecs list-services
--cluster meetup-demo

14. Describe service
$ aws ecs describe-services
--services our-demo
--cluster meetup-demo
