Lyrics

[Verse 1]
Starting with a cluster plan in mind
EKS for AWS, Azure's got AKS
GKE on Google Cloud you'll find
RKE2 when air-gapped networks last
Kubeadm builds from scratch with care
Choose your platform, environment aware

[Chorus]
Provision, deploy, monitor, upgrade
GitOps keeps your state in line
Terraform builds, Helm manages the stage
ArgoCD makes your clusters shine
Control plane up, then worker nodes
Infrastructure as Code flows

[Verse 2]
RKE2 stands for government grade
Air-gapped networks, DoD compliant
Security hardened, not afraid
Kubernetes distro, self-reliant
OpenTofu scripts the infrastructure
Helm charts wrap your workload mixture

[Chorus]
Provision, deploy, monitor, upgrade
GitOps keeps your state in line
Terraform builds, Helm manages the stage
ArgoCD makes your clusters shine
Control plane up, then worker nodes
Infrastructure as Code flows

[Verse 3]
GitOps brings declarative state
ArgoCD pulls from your repo
Flux detects when configs deviate
Reconciliation keeps the flow
Drift detection catches the changes
Declarative truth rearranges

[Bridge]
Prometheus scrapes the metrics true
Grafana paints the dashboard view
Alerting pipelines notify you
When something breaks or needs review
Version skew policies define
How far apart your versions align

[Verse 4]
Upgrade strategies take their turn
Control plane first, then worker fleet
Rolling updates help systems learn
Blue-green deployments can't be beat
Monitor health through every phase
Infrastructure as Code always pays

[Chorus]
Provision, deploy, monitor, upgrade
GitOps keeps your state in line
Terraform builds, Helm manages the stage
ArgoCD makes your clusters shine
Control plane up, then worker nodes
Infrastructure as Code flows

[Outro]
From provisioning to operation
Kubernetes lifecycle complete
Defense infrastructure automation
Makes your deployment process neat
