Knowledge
Sushil Poudel’s practical knowledge base on Kubernetes, FluxCD, Ceph, observability, and data quality, with links to the original technical documentation.
Practical explanations and diagnostic runbooks for the systems I work with. Each article links to technical sources and distinguishes general guidance from my project experience. Start with a runbook when you need a next step, or a learning note when you want the reasoning behind it.

LearningsStorage
Understand Ceph on bare-metal Kubernetes through Rook, OSDs, CRUSH placement, CSI provisioning, RBD and CephFS data paths, and storage policies.
LearningsData Engineering & Quality
Write data quality checks around explicit assumptions so failures explain what changed and which downstream output is at risk.
LearningsStorage
Treat volume snapshots as one recovery input and verify application restore, consistency, permissions, and target-cluster compatibility.
RunbooksStorage
Interpret Ceph health identifiers before choosing a recovery action or connecting storage warnings to workloads.
RunbooksKubernetes & GitOps
Diagnose a stalled Kubernetes deployment by checking rollout state, pod events, readiness, and GitOps recovery paths.
