Kubernetes YAML Tools
Generate correct Kubernetes YAML without copying an old manifest: Deployments, Services, Ingresses and other workload objects, plus Role/ClusterRole and binding pairs for RBAC.
Encode or decode Secret values and validate a kubeconfig file in your browser before kubectl reports a confusing error.

Guides: Docker & Kubernetes
- Kubernetes Jobs and CronJobsRun-to-completion Jobs, completions and parallelism, backoffLimit and activeDeadlineSeconds, CronJob schedules, concurrencyPolicy, startingDeadlineSeconds, and cleaning up finished jobs.
- Signing Container Images with cosignWhy image signing matters, keyless signing with Sigstore/Fulcio/Rekor, verifying in CI and at admission with policy-controller or Kyverno, attestations and SBOMs, and the gotchas.
- Kubernetes Version Upgrades Without DramaThe skew policy, the control-plane-then-nodes order, deprecated API migration, PodDisruptionBudgets and safe node draining, managed vs kubeadm, and testing before you touch prod.
- CoreDNS in KubernetesHow cluster DNS works, the Corefile and its plugins, the ndots:5 search-domain behaviour, NodeLocal DNSCache, tuning for scale, and debugging slow or failing in-cluster resolution.
- Horizontal Pod AutoscalingHow the HPA controller scales a Deployment on CPU, memory, or custom/external metrics, the scaling algorithm and stabilization windows, why requests must be set, and HPA + VPA + Cluster Autoscaler.
- Kubernetes Network PoliciesDefault-allow vs default-deny, ingress and egress rules, podSelector/namespaceSelector/ipBlock, why you need a CNI that enforces them, and testing that a policy actually blocks.
