Building your production tech stack for docker container platform
Bret Fisher's talk at DockerCon emphasizes building a robust Docker tech stack using Swarm for orchestration while avoiding vendor lock-in. He discusses strategies for deploying multi-tier applications with high availability, centralized monitoring, and logging. The presentation highlights the importance of starting simple and scaling as needed, along with utilizing open source tools for effective operations management.
