Hybrid Cloud GitOps Control Plane (Terraform + ArgoCD)
Hub-and-spoke GitOps platform: Terraform provisions OCI OKE (hub) and a spoke cluster, while Argo CD continuously reconciles platform + apps from Git.
Platform archive
Earlier Kubernetes, GitOps, and observability work. These hosted environments have been retired. The source, diagrams, and recorded screenshots remain useful engineering evidence.
How the deployments worked
- 01
Provision
Terraform provisioned the OCI hub and workload environments.
- 02
Build and reconcile
Jenkins built changes; Argo CD reconciled application and platform configuration from Git.
- 03
Run workloads
AKS and K3s supplied the workload environments described in the individual case studies.
- 04
Observe
The OKE hub collected metrics, logs, and traces through the LGTM stack and OpenTelemetry.
This is a summary of historical deployments, not a map of the current portfolio hosting. Individual case studies describe each topology and its limits.
Recorded case studies
Central Observability Hub (Terraform-provisioned OKE + ArgoCD-managed LGTM)
Terraform-provisioned OKE hub running an ArgoCD-managed LGTM stack (Grafana/Loki/Tempo) with OTLP ingestion and durable storage backends.
Rocket.Chat on Kubernetes (AKS GitOps + TLS + Cost Controls)
Rocket.Chat on AKS with Argo CD, Helm, TLS, external secrets, and scheduled scale-down windows.
