Containers, orchestration, cloud infrastructure, and the practices that keep production reliable.
The OCI launched in 2015 to standardize container images, runtime bundles, execution, and distribution across competing tools and vendors.
Prometheus became the CNCF's second hosted project in 2016, placing metrics and alerting beside orchestration at the center of cloud native systems.
Build a production-minded Kubernetes logging pipeline with Fluent Bit, Elasticsearch, Kibana, secure transport, retention, and failure controls.
Integrate Kubernetes workloads with HashiCorp Vault using scoped authentication, safe initialization, agent injection, rotation, and audit controls.
HashiCorp's 2023 Terraform license change triggered the OpenTF fork, soon renamed OpenTofu and placed under Linux Foundation stewardship.
How admission controllers intercept API requests before they're persisted, and how OPA/Gatekeeper turn that hook into cluster-wide policy enforcement.
How the OCI runtime and image specs standardized what a 'container' actually is, and how containerd/CRI-O/runc fit together beneath Docker and Kubernetes.
How Podman's daemon-less, fork-exec architecture differs from Docker's client-daemon model, and what that means for rootless containers in production.
Diagnose Kubernetes CrashLoopBackOff from events, previous logs, exit status, probes, configuration, and controlled debugging without erasing evidence.
Recover Docker disk space methodically by measuring images, containers, caches, volumes, and logs before pruning, then add safe recurrence controls.
