Bret Fisher hosts DevOps and Docker Talk: Cloud Native Interviews and Tooling alongside Nirmal Mehta, pulling conversations directly from their live audience sessions. This isn't a theoretical lecture series; it's grounded in the practical, often messy realities of building and running modern systems. Each episode digs into the specific tools and philosophies shaping infrastructure today, from the foundational elements like Docker and container orchestration with Kubernetes or Swarm to the broader cultural shifts of DevOps, SRE, and platform engineering. You'll hear discussions that span the entire software lifecycle, touching on the integration of security with DevSecOps, the automation promises of GitOps, and what "Cloud Native" truly means for development teams. The dialogue stays focused on actionable insights and real-world use cases, offering a genuine sense of what works and what doesn't in the field. For anyone navigating the container and cloud ecosystem, this podcast serves as a regular, insightful check-in with practitioners and experts, hosted by someone deeply embedded in the community. The natural, interview-driven format makes complex topics accessible, ensuring listeners come away with more than just buzzwords-they get context and clarity.
