Kubernetes & Containers¶
Three container-platform services — managed clusters, registry, and serverless.
-
Production-grade clusters; control plane managed by Cloud Digit.
-
OCI-compliant private registry with image scanning.
-
Run containers without managing nodes, billed per-request.
When to pick which¶
| Workload pattern | Pick |
|---|---|
| Long-running microservices, full K8s API | Managed Kubernetes |
| Bursty HTTP API, no infra ops appetite | Serverless Containers |
| Build/test pipelines pushing images | Container Registry (always) |
| K8s with custom CRDs / operators / GPUs | Managed Kubernetes + GPU VMs node pool |
What "managed" covers¶
| Component | Managed by Cloud Digit |
|---|---|
| Control plane | etcd, API server, scheduler, controller-manager (HA) |
| System addons | CoreDNS, CNI, ingress controller (NGINX or Traefik), metrics-server |
| Patching | K8s minor-version upgrades inside your maintenance window |
| Worker nodes | OS patching is automated; node pools you size and choose |
| Workloads | Yours — manifests, Helm charts, GitOps, RBAC inside the cluster |
Cluster sizing baseline¶
| Tier | Control plane | Worker pool size | Best for |
|---|---|---|---|
| Dev / staging | HA (3 nodes) | 2 × small | Pre-prod, internal tools |
| Production | HA (3 nodes) | 3 × medium minimum | Customer-facing apps |
| Regulated | HA (3 nodes), dedicated control plane | 3 × medium + isolated node groups | FI / regulated workloads |
