Containers, orchestration, cloud infrastructure, and the practices that keep production reliable.
Deploy and validate kube-prometheus-stack with persistent storage, secure Grafana access, bounded cardinality, alert routing, and recovery tests.
Build a reusable Helm chart with safe templates, documented values, schema validation, immutable images, release tests, and OCI packaging checks.
Docker donated containerd to the CNCF in 2017, giving the ecosystem a neutral, focused runtime foundation later adopted directly by Kubernetes.
Kubernetes 1.24 removed dockershim after a long deprecation, moving nodes to CRI-native runtimes without invalidating Docker-built OCI images.
Helm began at Deis in 2015, merged ideas with Deployment Manager, removed Tiller in Helm 3, and matured into Kubernetes package management.
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.
