Tilling the Brownfield: A Container Story
summary
Legacy web properties migrate incrementally from VMs to containers using CoreOS fleet, then Kubernetes, and finally Kubernetes to OpenShift Origin for security and user-management needs. A production front end runs on Docker serving 10 million requests per day, rising toward 40M, after piloting Docker-as-packaging and CI integration. Adoption accelerates when a security mandate shortens patch-to-deploy time. Pain points include a steep learning curve, hypervisor LRO breaking TCP, and device mapper bugs that require kernel and orchestration debugging.
