GitOps Workflow
Complete guide to implementing GitOps workflows with ArgoCD and Flux for automated Kubernetes deployments.
Purpose
Implement declarative, Git-based continuous delivery for Kubernetes using ArgoCD or Flux CD, following OpenGitOps principles.
Use this skill when
Set up GitOps for Kubernetes clusters
Automate application deployments from Git
Implement progressive delivery strategies
Manage multi-cluster deployments
Configure automated sync policies
Set up secret management in GitOps
Do not use this skill when
You need a one-off manual deployment
You cannot manage cluster access or repo permissions
You are not deploying to Kubernetes
Instructions
Define repo layout and desired-state conventions.
Install ArgoCD or Flux and connect clusters.
Configure sync policies, environments, and promotion flow.
Validate rollbacks and secret handling.
Safety
Avoid auto-sync to production without approvals.
Keep secrets out of Git and use sealed or external secret managers.
OpenGitOps Principles
Declarative - Entire system described declaratively
Versioned and Immutable - Desired state stored in Git
Pulled Automatically - Software agents pull desired state
Continuously Reconciled - Agents reconcile actual vs desired state
ArgoCD Setup
1. Installation # Create namespace
kubectl create namespace argocd
# Install ArgoCD
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
# Get admin password
kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d
Reference: See references/argocd-setup.md for detailed setup
2. Repository Structure gitops-repo/
├── apps/
│ ├── production/
│ │ ├── app1/
│ │ │ ├── kustomization.yaml
│ │ │ └── deployment.yaml
│ │ └── app2/
│ └── staging/
├── infrastructure/
│ ├── ingress-nginx/
│ ├── cert-manager/
│ └── monitoring/
└── argocd/

└── projects/
3. Create Application # argocd/applications/my-app.yaml
apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: my-app
namespace: argocd
spec:
project: default
source:
repoURL: https://github.com/org/gitops-repo
targetRevision: main
path: apps/production/my-app
destination:
server: https://kubernetes.default.svc
namespace: production
syncPolicy:
automated:
prune: true
selfHeal: true
syncOptions:
- CreateNamespace=true
4. App of Apps Pattern apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
name: applications
namespace: argocd
spec:
project: default
source:
repoURL: https://github.com/org/gitops-repo
targetRevision: main
path: argocd/applications
destination:
server: https://kubernetes.default.svc
namespace: argocd
syncPolicy:
automated: {}
Flux CD Setup
1. Installation # Install Flux CLI
brew install fluxcd/tap/flux
# Alternative: download the official installer, inspect it, then execute it
tmpdir="$(mktemp -d)"
trap 'rm -rf "$tmpdir"' EXIT
curl -fsSLo "$tmpdir/flux-install.sh" https://fluxcd.io/install.sh
cat "$tmpdir/flux-install.sh" # review the full installer before sudo
sudo bash "$tmpdir/flux-install.sh"
# Bootstrap Flux
flux bootstrap github \
--owner=org \
--repository=gitops-repo \
--branch=main \
--path=clusters/production \
--personal
2. Create GitRepository apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
name: my-app
namespace: flux-system
spec:
interval: 1m
url: https://github.com/org/my-app
ref:
branch: main
3. Create Kustomization apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
name: my-app
namespace: flux-system
spec:
interval: 5m
path: ./deploy
prune: true
sourceRef:
kind: GitRepository
name: my-app
Sync Policies
Auto-Sync Configuration syncPolicy:
automated:
prune: true # Delete resources not in Git
selfHeal: true # Reconcile manual changes
allowEmpty: false
retry:
limit: 5
backoff:
duration: 5s
factor: 2
maxDuration: 3m
spec:
interval: 1m
prune: true
wait: true
timeout: 5m
Reference: See references/sync-policies.md
Progressive Delivery
Canary Deployment with ArgoCD Rollouts apiVersion: argoproj.io/v1alpha1
kind: Rollout
metadata:
name: my-app
spec:
replicas: 5
strategy:
canary:
steps:
- setWeight: 20
- pause: {duration: 1m}
- setWeight: 50
- pause: {duration: 2m}
- setWeight: 100
Blue-Green Deployment strategy:
blueGreen:
activeService: my-app
previewService: my-app-preview
autoPromotionEnabled: false
Secret Management
External Secrets Operator apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
name: db-credentials
spec:
refreshInterval: 1h
secretStoreRef:
name: aws-secrets-manager
kind: SecretStore
target:
name: db-credentials
data:
- secretKey: password
remoteRef:
key: prod/db/password
Sealed Secrets # Encrypt secret
kubeseal --format yaml < secret.yaml > sealed-secret.yaml
# Commit sealed-secret.yaml to Git
Best Practices
Use separate repos or branches for different environments
Implement RBAC for Git repositories
Enable notifications for sync failures
Use health checks for custom resources
Implement approval gates for production
Keep secrets out of Git (use External Secrets)
Use App of Apps pattern for organization
Tag releases for easy rollback
Monitor sync status with alerts
Test changes in staging first
Troubleshooting argocd app get my-app
argocd app sync my-app --prune
argocd app diff my-app
argocd app sync my-app --force

Limitations
Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
