[DevoxxFR2014] Docker in Production: Lessons from the Trenches
Lecturer
Jérôme Petazzoni works as a Docker expert and previously served as an engineer at Docker Inc. He brings a strong background in system administration and distributed systems. Jérôme has deployed containerized workloads at scale in production environments. He frequently speaks on container orchestration, security, and operational best practices.
Abstract
This article distills hard-won production experience with Docker, covering networking, persistent storage, orchestration, and security. It examines common operational pitfalls—such as container sprawl, image bloat, and network complexity—and presents proven solutions including multi-stage builds, overlay networks, and Kubernetes integration. Real-world case studies from leading organizations illustrate strategies for achieving reliability, scalability, and security in containerized production systems.
Image Optimization and Build Strategies
Docker images must remain lean to ensure fast deployments and efficient resource usage. Multi-stage builds separate build-time dependencies from runtime artifacts:
