Quick Reference

Task	Command
Force sync all	flux reconcile ks flux-system --with-source
Suspend resource	flux suspend ks <name> -n <ns>
Resume resource	flux resume ks <name> -n <ns>
Check status	flux get all -A
View diff	flux diff ks <name> --path <local>

Reconciliation Management

Force Immediate Reconciliation

flux reconcile kustomization <name> -n <namespace> --with-source
flux reconcile helmrelease <name> -n <namespace> --with-source
flux reconcile source git <name> -n <namespace>
flux reconcile source oci <name> -n <namespace>
flux reconcile source helm <name> -n <namespace>

Suspend Reconciliation

flux suspend kustomization <name> -n <namespace>
flux suspend helmrelease <name> -n <namespace>
flux suspend source git <name> -n <namespace>

GitOps method (persisted, recommended):

apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  name: <name>
spec:
  suspend: true

Resume Reconciliation

flux resume kustomization <name> -n <namespace>
flux resume helmrelease <name> -n <namespace>

Rollback Strategies

Git Revert (Recommended)

git log --oneline -10
git revert <commit-sha>
git push origin main
flux reconcile kustomization flux-system --with-source

Version Pin

spec:
  chart:
    spec:
      version: "1.2.3"

Emergency Helm Rollback

flux suspend helmrelease <name> -n <namespace>
helm history <release-name> -n <namespace>
helm rollback <release-name> <revision> -n <namespace>
flux resume helmrelease <name> -n <namespace>

Drift Detection

Enable Drift Detection

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
spec:
  driftDetection:
    mode: enabled  # or 'warn'
    ignore:
      - paths: ["/spec/replicas"]
        target:
          kind: Deployment
      - paths: ["/metadata/annotations"]
        target:
          kind: Service

Check for Drift

kubectl get helmrelease <name> -n <ns> -o jsonpath='{.status.drift}'
flux diff kustomization <name> --path ./path/to/local

Flux Upgrade Procedures

Check Current Version

flux version
flux check

Upgrade Flux

brew upgrade fluxcd/tap/flux
flux install --export > flux-system/gotk-components.yaml
git add -A && git commit -m "Upgrade Flux to $(flux version --client)"
git push

Upgrade with Bootstrap

flux bootstrap github \
  --owner=<org> \
  --repository=<repo> \
  --branch=main \
  --path=./clusters/production \
  --personal

Multi-Cluster Operations

Switch Context

kubectl config get-contexts
kubectl config use-context <cluster-name>
flux check

Cross-Cluster Source Reference

apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
  name: shared-config
spec:
  url: https://github.com/org/shared-config
  ref:
    branch: main

HelmRelease Configuration

Remediation Settings

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
spec:
  install:
    remediation:
      retries: 3
  upgrade:
    remediation:
      retries: 5
      remediateLastFailure: true
    cleanupOnFail: true
  rollback:
    timeout: 5m
    recreate: false
    force: false
    cleanupOnFail: false
  test:
    enable: true

Disable Health Checks

spec:
  install:
    disableWait: true
  upgrade:
    disableWait: true

GitOps Best Practices

1. Prefer Git operations - Rollbacks via git revert maintain audit trail
2. Always resume suspended resources - Don't leave resources suspended indefinitely
3. Use --with-source - Ensures source is refreshed during reconciliation
4. Check dependsOn chains - Child resources need parents reconciled first
5. Document suspensions - Note why and when in commit messages
