Docker Compose• Distributed solutions

– Multiple containers

• Organization

– Single deployment doc

• Running

– Start, stop and scale

version: '3'

services:

elasticsearch: image: sixeyed/elasticsearch:nanoserver message-queue: image: nats:nanoserver

index-prospect-handler: image: sixeyed/product-launch-index-handler:v4 depends_on: - elasticsearch - message-queue

Docker Compose Fundamentals• Organizing distributed solutions

– Single definition | Multiple environments

• Managing multi-container solutions

– Start, stop, scale | Update

• Client-side tool

– Local YAML file | Remote Docker engine

Docker Swarm

Manager Worker WorkerWorker

Docker Swarm Fundamentals• Native Docker clustering

– OS | Docker

• Manager-worker architecture

– High-availability | Scale out

• Zero-downtime updates

– Application updates | Node patching
