Core Helper Functions

#!/bin/bash

# Flux CLI wrapper
flux_cmd() {
    flux "$@" --namespace "${FLUX_NAMESPACE:-flux-system}" 2>/dev/null
}

# kubectl wrapper for Flux CRDs
flux_k8s() {
    kubectl "$@" -n "${FLUX_NAMESPACE:-flux-system}" 2>/dev/null
}

# Get Flux status across all resource types
flux_status() {
    flux_cmd get all 2>/dev/null || {
        echo "=== Sources ==="
        flux_k8s get gitrepositories,helmrepositories,ocirepositories,buckets 2>/dev/null
        echo "=== Kustomizations ==="
        flux_k8s get kustomizations 2>/dev/null
        echo "=== HelmReleases ==="
        flux_k8s get helmreleases -A 2>/dev/null
    }
}

MANDATORY: Discovery-First Pattern

Always discover all Flux resources before querying specific reconciliation status.

Phase 1: Discovery

#!/bin/bash

echo "=== Flux Version & Components ==="
flux_cmd version 2>/dev/null || \
    flux_k8s get deployments -l app.kubernetes.io/part-of=flux -o custom-columns="NAME:.metadata.name,READY:.status.readyReplicas,IMAGE:.spec.template.spec.containers[0].image" 2>/dev/null

echo ""
echo "=== Flux Resources Overview ==="
flux_cmd get all -A 2>/dev/null | head -30 || {
    echo "--- GitRepositories ---"
    flux_k8s get gitrepositories -A -o custom-columns="NAMESPACE:.metadata.namespace,NAME:.metadata.name,READY:.status.conditions[0].status,STATUS:.status.conditions[0].message" 2>/dev/null | head -10
    echo "--- Kustomizations ---"
    flux_k8s get kustomizations -A -o custom-columns="NAMESPACE:.metadata.namespace,NAME:.metadata.name,READY:.status.conditions[0].status,STATUS:.status.conditions[0].message" 2>/dev/null | head -10
    echo "--- HelmReleases ---"
    flux_k8s get helmreleases -A -o custom-columns="NAMESPACE:.metadata.namespace,NAME:.metadata.name,READY:.status.conditions[0].status,STATUS:.status.conditions[0].message" 2>/dev/null | head -10
}

Output Rules

TOKEN EFFICIENCY: Target 50 lines per output
Use flux get for human-friendly output, kubectl -o json | jq for structured queries
Truncate long status messages — Flux messages can be verbose

Common Operations

#!/bin/bash

' | column -t

Anti-Hallucination Rules

NEVER guess Kustomization or source names — always list first
NEVER fabricate revision hashes — query source status for actual revisions
NEVER assume namespace — Flux resources can exist in any namespace
CRD group names are long (e.g., kustomizations.kustomize.toolkit.fluxcd.io) — use correct full names with kubectl

Safety Rules

NEVER suspend Flux reconciliation without explicit user confirmation
NEVER delete sources or Kustomizations without understanding dependencies
NEVER force reconciliation in production without user approval
Prune-enabled Kustomizations will DELETE resources removed from Git — flag when prune: true

Output Format

Present results as a structured report:

Managing Flux Report
════════════════════
Resources discovered: [count]

Resource       Status    Key Metric    Issues
──────────────────────────────────────────────
[name]         [ok/warn] [value]       [findings]

Summary: [total] resources | [ok] healthy | [warn] warnings | [crit] critical
Action Items: [list of prioritized findings]

Target ≤50 lines of output. Use tables for multi-resource comparisons.

Counter-Rationalizations

Shortcut	Counter	Why
"I'll skip discovery and check known resources"	Always run Phase 1 discovery first	Resource names change, new resources appear — assumed names cause errors
"The user only asked for a quick check"	Follow the full discovery → analysis flow	Quick checks miss critical issues; structured analysis catches silent failures
"Default configuration is probably fine"	Audit configuration explicitly	Defaults often leave logging, security, and optimization features disabled
"Metrics aren't needed for this"	Always check relevant metrics when available	API/CLI responses show current state; metrics reveal trends and intermittent issues
"I don't have access to that"	Try the command and report the actual error	Assumed permission failures prevent useful investigation; actual errors are informative

Common Pitfalls

CRD naming: Flux Kustomization CRD is kustomizations.kustomize.toolkit.fluxcd.io, not kustomizations (conflicts with kustomize.config.k8s.io)
Reconciliation interval: Short intervals increase Git API calls — check rate limits
Suspend vs delete: Suspending stops reconciliation; deleting removes the resource but NOT managed workloads (unless prune is on)
Dependency ordering: Kustomizations can depend on each other — check dependsOn field for ordering issues
Health checks: Kustomizations with healthChecks block until resources are healthy — long deployments may timeout
Secret decryption: SOPS/age-encrypted secrets need decryption keys — check Flux secret for decryption key
Multi-tenancy: Flux supports multi-tenancy — ServiceAccount impersonation controls permissions per tenant
