Docker Compose has always been at the heart of Rancher

• Describe deployments• Launch Stacks• Execute upgrades• Define Service Discovery

Policies• Describe Scheduling Rules• Inject Environment

Variables• Program Load Balancers

Microservices architectures increase the Proliferation of Docker Compose

Compose files change throughout the lifecycle of a stack

Late last year we introduced the Rancher Catalog

- Exposes Docker Compose Templates stored in GitHub

- Started with a set of public templates for common services

- Allows configuration and deployment of stacks

- Supports versioning and upgrades

- Just added support for private catalogs
