EC2 Container Service
- 1. Introduction to Amazon EC2 Container Service and setting up build pipeline with ECS and Jenkins Swapnil Dahiphale DevOps Engineer, WhiteHedge Technologies
- 2. Agenda • Containers • Orchestration • Why ECS? • What is ECS? • Key Components • Typical user workflow • Build pipeline with Jenkins and ECS
- 3. Containers “automates the deployment of any application as a lightweight, portable, self-‐sufficient container that will run virtuallyanywhere”
- 4. What are containers? OS virtualization Process isolation Automation Images Server Guest OS Bins/Libs Bins/Libs App2App1
- 5. Why use Docker? With Docker we can solve many problems • “it works on my machine” • reducing build & deploy time • Infrastructure configuration –automation! • Libs dependency hell • Cost control and granularity
- 7. A container pipeline IT Operations Base Image PatchesUtilities
- 8. A container pipeline IT Operations Base Image PatchesUtilities Ruby Redis Logger
- 9. A container pipeline IT Operations Developer Base Image PatchesUtilities Ruby Redis Logger App
- 10. A container pipeline Base Image PatchesUtilities IT Operations Developer Ruby Redis Logger App
- 11. Orchestration!
- 12. Orchestration is a mean to Automate Manual Process Orchestration
- 13. Why Orchestration? • Microservice Architectures • Fault tolerance / High Availability • Scalability • Resource Utilization
- 14. Orchestration Tools • Kubernetes • Docker Swarm • Amazon EC2 Container Service
- 15. Why EC2 Container Service ?
- 18. What is ECS? Building Block Service
- 19. What is ECS? Easily Manage Clusters for Any Scale • Nothing to run • Complete state • Control and monitoring • Scale ECS List* and Describe* APIactions
- 20. What is ECS? Flexible Container Placement • Applications • Batch jobs • Multiple schedulers
- 21. What is ECS? Designed for use with other AWS services • Virtual Private Cloud • Elastic Load Balancing • Elastic Block Store • IAM • CloudTrail
- 22. What is ECS? Performance at scale
- 23. What is ECS? Secure Your containers, Your instances
- 24. What is ECS? Extensible • ComprehensiveAPIs • Open sourceagent • Customschedulers
- 26. Key Components: Container Instances Amazon EC2 instances Docker daemon Amazon ECS agent
- 27. Key Components: Clusters Regional Resource pool Grouping of Container Instances Start empty, dynamically scalable
- 28. Key Components: Tasks Unit of work Grouping of related containers Run on Container Instances

- 32. Typical user workflow I want to run aservice
- 33. Typical user workflow Run Instances Amazon EC2 Use custom AMI with Docker support and ECS Agent. Instances will register with default cluster.
- 34. Typical user workflow Create Task Definition Declare resource requirements for containers Shared Data Volume Node.jsApp Time of day App
- 35. Typical user workflow Create Service Declare resource requirements for service Shared Data Volume Node.jsApp Time of day App Elastic Load Balancing X 5
- 36. Typical user workflow Describe Service
