Use when authoring or hardening the Kubernetes workload manifest set for a service after infrastructure-platform and backend-architecture have decided the runtime substrate, workload class, and release strategy. Produces Deployment / StatefulSet / DaemonSet / Job / CronJob, Service, Ingress, a baseline HPA and PDB, ConfigMap/Secret-referenced configuration injection, distinct startup/readiness/liveness probes, mandatory resource requests and limits, and tier-correct rolling-update parameters — plus container packaging via the language sub-skills. This is the archetype-scoped authoring successor to the k8s-deploy-manifest-review omnibus. Do not use for NetworkPolicy/RBAC depth, autoscaling/PDB sizing and resilience topology, observability wiring, image hardening and admission control, or cluster provisioning; use the other Family G archetype skills (cluster provisioning is out of family).

Kubernetes Workload Packaging and Manifest
When to use
Invoke when shipping a workload to Kubernetes for the first time, materially changing a workload's manifest set, or hardening inherited manifests for production-readiness authoring. This skill owns the authoring of the manifest slice; the k8s-deploy-manifest-review omnibus remains the holistic cross-archetype review pass.
Do not use for: NetworkPolicy / ServiceAccount / RBAC depth (use k8s-network-and-identity-policy); HPA/VPA/KEDA tuning, PDB sizing, anti-affinity, topology spread, graceful shutdown (use k8s-scaling-and-resilience-topology); metrics/log/trace wiring and ServiceMonitor (use k8s-observability-and-operations-readiness); image hardening, signing, SBOM, admission control (use k8s-supply-chain-and-image-hardening); cluster provisioning, node pools, control-plane topology (out of Family G — owned by the cloud platform stack and Terraform).
Inputs
Required:
A container image reference (registry + tag, digest-pinnable) or the source to package via a language sub-skill.
Approved infrastructure-platform.md, or explicit confirmation it is intentionally deferred.
Optional:
Approved backend-architecture.md for workload class, resource expectations, and operational contracts.
The workload's tier from architecture-schema (drives replica and PDB defaults).
Configuration and secret keys the workload consumes (names only; values are never authored here).
Stateful requirements (persistent volumes, ordered identity) if the workload is not stateless.
Operating rules
Never generate tutorial-grade manifests. Assume production: probes that actually gate traffic, both resource requests and limits, a digest-pinned image, and a declared rollback.
Consume infrastructure-platform.md and backend-architecture.md; do not invent decisions. Runtime substrate, workload class, release strategy, and resource expectations come from upstream. If a needed decision is missing, pause and raise an ADR candidate rather than guessing.
Select the workload kind from the class, not by habit. Stateless API → Deployment; ordered/identity-bound → StatefulSet; node-local agent → DaemonSet; run-to-completion → Job; scheduled → CronJob. Justify the choice against the workload class.
Every container has resources.requests AND resources.limits. A container without both is rejected — it breaks scheduling fairness and node stability.
The three probes are distinct and purposeful. startupProbe covers slow init, readinessProbe gates traffic, livenessProbe restarts a hung process. Reusing one endpoint for all three, or omitting readiness, is rejected.
The image is referenced by digest where the registry supports it; imagePullPolicy is explicit. A floating :latest tag is rejected for any promotable environment.
Configuration is injected, never baked. Config via ConfigMap, secrets via Secret reference (the reference only — secret values and the secret backend are owned upstream/by the security archetype). No environment-branched manifests.
Author a tier-correct baseline HPA and PDB so the workload is not born unsafe, but defer sizing and resilience topology to k8s-scaling-and-resilience-topology. Set a safe default; mark the tuning handoff explicitly.
Set the pod-template security-context baseline (non-root, drop ALL, no privilege escalation, read-only root FS) as a floor; deep image hardening, signing, and admission control are the supply-chain archetype's ownership — name the handoff.
Rolling-update parameters match the tier. maxUnavailable: 0 for tier-0/1 availability-critical workloads; tighter surge for capacity-constrained clusters. The release strategy (blue-green/canary) is consumed from upstream, not invented.
This skill owns the manifest set + packaging entrypoint. NetworkPolicy/RBAC depth, autoscaling tuning, observability wiring, and image hardening are named handoffs, not implemented here.
A manifest set that does not kubectl apply --dry-run=server cleanly and pass a schema/policy lint is not done.
Output contract
The generated manifest set MUST conform to:
deployment-standards — rolling update default; tier-0 requires canary or blue-green per upstream; readiness/liveness probes mandatory; rollback artifact declared; env-agnostic (no env-branched manifests, no baked config).
security-standards — security-context baseline (runAsNonRoot, readOnlyRootFilesystem, allowPrivilegeEscalation: false, drop ALL capabilities), non-default ServiceAccount referenced (RBAC depth deferred), no secret values in manifests.
observability-standards — logs to stdout; Prometheus scrape annotation or ServiceMonitor seam present (full wiring deferred to the observability archetype).
naming-conventions — resource names kebab-case, suffixed by kind when ambiguous; labels follow the recommended app.kubernetes.io/* set.
Upstream contract: infrastructure-platform.md is the source of truth for runtime substrate, release strategy, and packaging strategy; backend-architecture.md is the source of truth for workload class and resource expectations. If a needed decision is missing, pause and raise an ADR candidate. NetworkPolicy/RBAC, autoscaling tuning, observability wiring, and image hardening are named handoffs.
Progressive references
Read references/k8s-workload-manifest-playbook.md when authoring any owned resource or checking the anti-pattern list.
Read references/k8s-workload-manifest-quality-rubric.md before declaring the manifest set complete.
Use assets/k8s-workload-manifest.template.md as the manifest-set and label/probe-pattern reference.
Process
Gather context: load infrastructure-platform.md (Workload Inventory, Runtime Substrate Selection, Deployment & Release Architecture, Packaging & Artifact Strategy) and backend-architecture.md (workload class, resource expectations, operational contracts). Resolve the workload tier from architecture-schema. If a needed decision is missing, raise an ADR candidate before proceeding.
Package the container: invoke the matching language sub-skill (dockerfile-and-jvm-tuning for JVM; the planned non-JVM siblings for Python/Node/Go/.NET/static). Obtain a digest-pinnable image reference.
Select the workload kind from the class and author the controller (Deployment / StatefulSet / DaemonSet / Job / CronJob) with replicas from the tier default, the security-context baseline, and explicit imagePullPolicy.
Set resource requests and limits on every container, derived from the upstream resource expectation — never blank, never guessed silently.
Author the three distinct probes: startupProbe (slow init budget), readinessProbe (traffic gate), livenessProbe (hang restart). Endpoints and thresholds differ by purpose.
Author Service (ClusterIP unless upstream declares external) and Ingress where the workload is externally reached, referencing the upstream traffic shape.
Wire configuration injection: ConfigMap for config, Secret references for secrets (names only). No values, no env-branched manifests.
Author the tier-correct baseline HorizontalPodAutoscaler and PodDisruptionBudget (PDB required when replicas > 1) as safe defaults, with an explicit handoff comment to k8s-scaling-and-resilience-topology for sizing.
Set rolling-update parameters per tier (maxUnavailable: 0 for availability-critical); honor the upstream release strategy (blue-green/canary handed off to the delivery mechanics, not invented here).
Verify: kubectl apply --dry-run=server (or kubeconform/kubectl --dry-run=client where no cluster) passes; a schema/policy lint passes; document any check that cannot run in the environment.
Emit the manifest set under k8s/ plus deploy.md (rollout + rollback) and the explicit handoff list. Validate against deployment-, security-, observability-standards, naming-conventions, and architecture-schema. Revise until all pass or the gap is documented.
