Kubernetes GitOps

GitOps workflows using Flux and ArgoCD with kubectl-mcp-server tools.

When to Apply

Use this skill when:

• User mentions: "Flux", "ArgoCD", "GitOps", "sync", "reconcile"
• Operations: checking sync status, triggering reconciliation, drift detection
• Keywords: "out of sync", "deploy from git", "continuous delivery"

Priority Rules

Priority	Rule	Impact	Tools
1	Check source readiness before troubleshooting	CRITICAL	flux_sources_list_tool
2	Verify sync status before deployments	HIGH	argocd_app_get_tool
3	Reconcile after git changes	MEDIUM	flux_reconcile_tool
4	Suspend before manual changes	LOW	flux_suspend_tool

Quick Reference

Task	Tool	Example
List Flux kustomizations	flux_kustomizations_list_tool	flux_kustomizations_list_tool(namespace)
Reconcile Flux	flux_reconcile_tool	flux_reconcile_tool(kind, name, namespace)
List ArgoCD apps	argocd_apps_list_tool	argocd_apps_list_tool(namespace)
Sync ArgoCD	argocd_sync_tool	argocd_sync_tool(name, namespace)

Flux CD

Check Flux Status

flux_kustomizations_list_tool(namespace="flux-system")
flux_helmreleases_list_tool(namespace)
flux_sources_list_tool(namespace="flux-system")

Reconcile Resources

flux_reconcile_tool(
    kind="kustomization",
    name="my-app",
    namespace="flux-system"
)

flux_reconcile_tool(
    kind="helmrelease",
    name="my-chart",
    namespace="default"
)

Suspend/Resume

flux_suspend_tool(kind="kustomization", name="my-app", namespace="flux-system")

flux_resume_tool(kind="kustomization", name="my-app", namespace="flux-system")

See FLUX.md for detailed Flux workflows.

ArgoCD

List Applications

argocd_apps_list_tool(namespace="argocd")

Get App Status

argocd_app_get_tool(name="my-app", namespace="argocd")

Sync Application

argocd_sync_tool(name="my-app", namespace="argocd")

Refresh App

argocd_refresh_tool(name="my-app", namespace="argocd")

See ARGOCD.md for detailed ArgoCD workflows.

GitOps Troubleshooting

Flux Not Syncing

Symptom	Check	Resolution
Source not ready	flux_sources_list_tool()	Check git credentials
Kustomization failed	flux_kustomizations_list_tool()	Check manifest errors
HelmRelease failed	flux_helmreleases_list_tool()	Check values, chart version

ArgoCD Out of Sync

Symptom	Check	Resolution
OutOfSync	argocd_app_get_tool()	Manual sync or check auto-sync
Degraded	Check health status	Fix unhealthy resources
Unknown	Refresh app	argocd_refresh_tool()

Environment Promotion

With Flux Kustomizations

flux_reconcile_tool(kind="kustomization", name="staging", namespace="flux-system")

flux_reconcile_tool(kind="kustomization", name="production", namespace="flux-system")

With ArgoCD

argocd_sync_tool(name="app-staging", namespace="argocd")

argocd_app_get_tool(name="app-staging", namespace="argocd")

argocd_sync_tool(name="app-production", namespace="argocd")

Multi-Cluster GitOps

Manage GitOps across clusters:

flux_kustomizations_list_tool(namespace="flux-system", context="cluster-1")
flux_kustomizations_list_tool(namespace="flux-system", context="cluster-2")

flux_reconcile_tool(
    kind="kustomization",
    name="apps",
    namespace="flux-system",
    context="production-cluster"
)

Drift Detection

Compare live state with desired:

argocd_app_get_tool(name="my-app", namespace="argocd")

flux_kustomizations_list_tool(namespace="flux-system")

Prerequisites

• Flux: Required for Flux tools

  flux install
  

• ArgoCD: Required for ArgoCD tools

  kubectl create namespace argocd
  kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
