The smallest deployable unit in Kubernetes:
apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
containers:
- name: app
image: nginx:1.21
Maintains a stable set of replica Pods:
apiVersion: apps/v1
kind: ReplicaSet
metadata:
name: my-replicaset
spec:
replicas: 3
selector:
matchLabels:
app: my-app
template:
# Pod template
Manages ReplicaSets and provides declarative updates:
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-deployment
spec:
replicas: 3
strategy:
type: RollingUpdate
rollingUpdate:
maxSurge: 1
maxUnavailable: 0
# ...
Exposes Pods to network traffic:

npx claudepluginhub thebushidocollective/han --plugin kubernetesGuides step-by-step creation of production-ready Kubernetes manifests including Deployments, Services, ConfigMaps, Secrets, and PersistentVolumeClaims.
Provides YAML examples and best practices for Kubernetes manifests: Pods, Deployments, Services, ConfigMaps, Secrets, probes, resources, labels, and kubectl validation.
Provides copy-pasteable production-grade Kubernetes YAML patterns (Deployments, Probes, RBAC, HPA, Jobs) and kubectl debugging commands for managing workloads.
