Summary
🤩
Rockstar🎓
Top SchoolAlexander Trost is a Senior Principal Kubernetes Architect in Remchingen, Germany, with 10 years of Linux, container and cloud-native storage experience. A Rook maintainer and CKA, he has driven substantive enhancements to storage orchestration and containerized Ceph—implementing Ceph monitor health checks, CephCluster CRD configurability, host-network support, and RBD/FlexVolume fixes. He pairs hands-on sysadmin and DevOps skills with architect-level thinking, improving observability, security contexts, and reliability across projects like rook/rook, ceph-container, stash and Kubernetes contrib. As a founder and consultant he brings entrepreneurial focus to production-scale problems, and—less obvious—balances deep storage internals work with a hobbyist gamer’s curiosity that keeps his tooling pragmatic and user-focused.
