deploy-isovalent-lab

name	deploy-isovalent-lab
description	Install, configure, validate, or adapt the Isovalent components in this repository for Kubernetes, Amazon EKS, or OpenShift. Use when Codex needs to work with Cilium Enterprise, Hubble, Tetragon, DNS proxy HA, platform-specific Helm values, or Kubernetes/OpenShift differences for the Isovalent stack.

Deploy Isovalent Lab

Use this skill for the Isovalent side of the repo. If the task is primarily about the Splunk OpenTelemetry Collector, Operator, auto-instrumentation, metric filtering, or dashboard imports, use deploy-splunk-o11y-lab.

Quick Start

1. Read references/repo-map.md.
2. Decide which platform path applies:
   • Read references/kubernetes.md for EKS or standard Kubernetes.
   • Read references/openshift.md for OpenShift.
3. Pull in the O11y skill separately if the task also changes collector selectors, dashboards, or Splunk distribution settings.

Workflow

1. Establish scope.
   • Determine whether the task is cluster bootstrap, Cilium install, Hubble or Envoy tuning, Tetragon enablement, DNS proxy HA, validation, or troubleshooting.
   • Prefer discovery over reinstall when the user already has a cluster.
2. Inventory the cluster before changing anything.
   • Check namespaces, Helm releases and release status, installed CRDs, ServiceMonitors, and running Isovalent workloads.
   • Confirm whether the cilium, cilium-dnsproxy, and tetragon releases have created Cilium, Envoy, operator, Hubble Relay, Hubble Timescape, DNS proxy HA, and Tetragon operator resources before applying charts.
   • Refresh the Helm repos and compare installed chart versions to the latest official isovalent/* chart versions before deciding whether to upgrade.
   • If a previous upgrade may have used --reuse-values, inspect computed Helm values or rendered manifests for stale image tags before assuming the runtime moved with the chart revision.
   • Prefer the live release state over older doc names or versions when they disagree.
3. Reuse repo artifacts.
   • Treat examples/ as the source of truth for Isovalent values and bootstrap files.
   • Treat the prose docs as operator guidance, not immutable truth, because the repo has a few command and version inconsistencies.
4. Apply the platform branch.
   • For Kubernetes or EKS, keep the repo's EKS workflow only when AWS is actually the target.
   • For generic Kubernetes, keep the observability-facing Isovalent values but strip AWS-only networking assumptions.
   • For OpenShift, follow the OpenShift-specific branch and do not reuse the EKS bootstrap files unchanged.
5. Validate the install.
   • Confirm pod rollouts, service exposure, ServiceMonitors, metrics ports, and any platform-specific constraints before handing off to O11y validation.

Non-Negotiables

• Do not assume the EKS-specific values in examples/cilium-enterprise-values.yaml are portable to OpenShift or generic Kubernetes.
• Preserve Hubble, Envoy, operator, and Tetragon observability settings unless the platform or packaging makes them invalid.
• Resolve latest chart versions from the official Helm repos at runtime instead of trusting stale hard-coded pins.
• Keep the DNS proxy chart version aligned with the actual Cilium version in use.
• Preserve Hubble Relay, Hubble Timescape, and the separate cilium-dnsproxy release when they already exist.
• Do not default to --reuse-values for cilium or cilium-dnsproxy when upgrading to the latest chart versions. Reapply the intended values file or explicit live values so Helm does not preserve stale computed image tags.
• Do not assume every Isovalent subcomponent image tag numerically matches the chart version. Compare live images against rendered manifests or chart defaults; Hubble Timescape can intentionally track its own tag inside the Cilium chart.
• Do not pull Splunk collector settings such as distribution or cloudProvider into Isovalent chart values. Those belong to deploy-splunk-o11y-lab.
• Prefer adapting an existing Cilium or Tetragon install over reinstalling it blindly.

Validation Checklist

• Cilium agent, Hubble, Envoy, operator, and Tetragon metrics ports match the repo assumptions.
• DNS proxy HA still exposes service cilium-dnsproxy on 9967 when that component is enabled.
• Helm status and runtime state agree for cilium, cilium-dnsproxy, and tetragon, or any mismatch is explained before changing the releases.
• The live container images for Cilium, Envoy, operator, relay, and DNS proxy match the intended chart train instead of just the Helm release metadata.
• Any transient Hubble Relay NOT_SERVING state during a Cilium rollout is resolved or explicitly traced to hubble-peer or certificate convergence before rollback.
• k8sServiceHost has been replaced with the real API server endpoint when using the EKS values file.
• Namespaces and workload labels still line up with the repo's observability assumptions. If not, hand the collector relabel work to deploy-splunk-o11y-lab.
• OpenShift-specific constraints were handled explicitly instead of reusing AWS or generic Kubernetes settings.
