Containers, orchestration, cloud infrastructure, and the practices that keep production reliable.
A complete walkthrough deploying Prometheus to scrape cluster metrics and Grafana to visualize them — the standard monitoring pairing across the cloud-native ecosystem.
A complete walkthrough building a Helm chart for a simple application — templates, values, and the conventions that make a chart genuinely reusable rather than a one-off wrapper around raw YAML.
Accepted as an incubating CNCF project on March 29, 2017, containerd split out the core container-runtime functionality from Docker itself — becoming the shared runtime foundation much of the ecosystem, including Kubernetes, later standardized on.
Deprecated in December 2020 and fully removed in the April 2022 release of Kubernetes 1.24, dockershim's removal ended direct Docker Engine support in kubelet — a roughly 16-month migration window the project deliberately built in.
Started as a Deis project on October 15, 2015, Helm brought familiar package-manager concepts to Kubernetes — later merging with Google's Deployment Manager to become the Helm 2 the ecosystem would standardize on.
Founded June 22, 2015 by Docker, CoreOS, and a broad industry coalition, the OCI set out to make container images and runtimes portable across tools and vendors rather than tied to any one implementation.
Accepted on May 9, 2016, Prometheus became the CNCF's second project after Kubernetes itself — an early, deliberate signal that observability, not just orchestration, belonged at the center of the cloud-native stack.
A complete walkthrough deploying Fluent Bit, Elasticsearch, and Kibana to collect and search logs from every pod in a cluster — one place to look instead of kubectl logs against dozens of pods individually.
A complete walkthrough deploying Vault, storing a secret, and retrieving it from a Kubernetes pod dynamically — instead of secrets sitting as plain base64 in a Kubernetes Secret object.
HashiCorp moved Terraform to the Business Source License on August 10, 2023; within six weeks, a community fork called OpenTF (soon renamed OpenTofu) had gathered 33,000 GitHub stars and joined the Linux Foundation.
