Containerization and Orchestration Questions

End to end container platform knowledge covering both containerization and orchestration at production scale. This includes advanced Docker topics such as image optimization, container networking at scale, build pipelines and registries, and security considerations, plus advanced Kubernetes topics such as cluster management, performance tuning, multi cluster strategies, custom controllers and operators, service mesh and ingress architectures, storage classes and persistent volumes, monitoring and logging, cost optimization, and real world operational challenges. Candidates should be prepared to discuss trade offs between managed and self managed services, deployment strategies, scaling patterns, and lessons learned from production incidents.
