Building GitOps Workflows

Name: building-gitops-workflows
Author: jeremylongshore

Overview

Construct GitOps workflows using ArgoCD or Flux to implement declarative, Git-driven continuous delivery for Kubernetes. Generate Application/Kustomization manifests, configure sync policies, set up multi-environment promotion, and implement RBAC and notification integrations.

Prerequisites

Kubernetes cluster accessible via kubectl with admin permissions
Git repository for storing Kubernetes manifests (separate from application code recommended)
ArgoCD or Flux installed on the cluster, or Helm charts ready for installation
Container images built and pushed to a registry accessible from the cluster
SSH key or access token for Git repository authentication from the cluster

Instructions

Choose the GitOps tool based on requirements: ArgoCD for UI-driven management, Flux for lightweight Git-native approach
Design the repository structure: environments/{dev,staging,prod}/ with Kustomize overlays or Helm values per environment
Generate ArgoCD Application or Flux Kustomization manifests pointing to the Git repository path for each environment
Configure sync policy: enable automated.selfHeal and automated.prune for non-production; use manual sync for production
Set up Git repository credentials as a Kubernetes Secret for the GitOps operator
Implement environment promotion: update the image tag in staging manifests, test, then promote to production via PR
Configure notifications: Slack/email alerts on sync success, failure, or health degradation via ArgoCD Notifications or Flux Alert Provider
Add RBAC: restrict who can sync production applications and who can modify GitOps configurations
Validate the setup: push a manifest change to Git and verify the GitOps operator detects and applies it within the sync interval

Output

ArgoCD Application or Flux Kustomization manifests per environment
Git repository structure with Kustomize bases and overlays
RBAC configuration (ArgoCD AppProject, Kubernetes RBAC)
Notification configuration (Slack webhooks, email)
CI pipeline step to update image tags in the GitOps repository after build

Error Handling

Error	Cause	Solution
`ComparisonError: Failed to load target state`	Invalid manifest path or Git ref	Verify `path:` and `targetRevision:` in the Application manifest; check repo structure
`Authentication failed for repository`	SSH key or token not configured or expired	Create/update the Git credentials Secret; verify deploy key has read access
`Application is OutOfSync but not syncing`	Automated sync disabled or sync window closed	Enable `automated:` in syncPolicy or trigger manual sync with `argocd app sync`
`Resource already exists and is not managed`	Resource created outside of GitOps	Add the `argocd.argoproj.io/managed-by` annotation or delete the conflicting resource
`Sync failed: health check timeout`	Application pods not becoming ready after sync	Check pod logs; verify resource requests fit node capacity; increase health check timeout

Examples

"Set up ArgoCD with three Application manifests for dev, staging, and production, each pointing to a different Kustomize overlay in the GitOps repo."
"Configure Flux with automatic image updates: scan ECR for new tags matching v*, update the staging manifests, and create a PR for production promotion."
"Create an ArgoCD AppProject that restricts the production application to specific namespaces and requires manual sync with admin-only access."
