Lyrics

[Verse 1]
When clusters need their birthplace planned
EKS on Amazon's command
Azure's AKS for Microsoft's realm
GKE where Google's at the helm
But when the air is gapped and sealed
RKE2 becomes the shield
Government's chosen distribution
Built for classified solution

[Chorus]
Provision, reconcile, upgrade, observe
Every cluster's got to serve
Terraform scripts the infrastructure code
Helm deploys the workload load
GitOps watches every state
ArgoCD won't hesitate
Prometheus alerts when metrics spike
Keep your clusters running right

[Verse 2]
Infrastructure as Code declares
Every resource, every layer
OpenTofu or Terraform's way
Reproducible every day
Helm charts package your application
Templated configuration
Version controlled and tested clean
Best deployment you've ever seen

[Chorus]
Provision, reconcile, upgrade, observe
Every cluster's got to serve
Terraform scripts the infrastructure code
Helm deploys the workload load
GitOps watches every state
ArgoCD won't hesitate
Prometheus alerts when metrics spike
Keep your clusters running right

[Verse 3]
GitOps pulls from repository
Flux and Argo tell the story
Declarative state's the only truth
Drift detection finds the proof
When reality diverges far
Reconciliation heals the scar
Git commits become the plan
Automated where you can

[Chorus]
Provision, reconcile, upgrade, observe
Every cluster's got to serve
Terraform scripts the infrastructure code
Helm deploys the workload load
GitOps watches every state
ArgoCD won't hesitate
Prometheus alerts when metrics spike
Keep your clusters running right

[Bridge]
Control plane first, then worker nodes
Version skew policy explodes
Rolling updates, blue-green switch
Canary testing finds each glitch
Grafana dashboards paint the scene
Alertmanager keeps it clean

[Outro]
From provisioning to final call
Kubernetes manages it all
Infrastructure carved in code
Monitoring the entire load
