Building Your Docker Swarm Tech Stack

Presented at DockerCon 2018 EU, I go through using Docker and the Swarm Orchestrator (a simpler Kuberentes) to stack different tools up from the base OS to a full-featured production server cluster. Also, Sci-Fi. The Video to this deck will be at https://www.bretfisher.com/docker once they are posted.

2. People ask "Where's my LAMP for container clusters?" Your solutions will be a "stack" of infrastructure tools Cloud-native container tools are new We need patterns and examples of full cluster stacks Problem: No Server Tool Lives In Isolation
3. Build examples of full-ish stacks on different tools Options for solo to medium-sized DevOps/Ops teams Use Docker Swarm latest stable as orchestrator Limit cloud vendor lock-in* 4 Goals for Today * Lock-in: A service I can't swap out in my server stack
4. The Duality of Container Infrastructure “It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity...” Charles Dickens A Tale of Two Cities, 1859
5. Clusters are Complex Start small and simple, grow them as you grow
