Kubernetes Consulting
Production-grade Kubernetes clusters that won't keep your team up at night — DR-tested, CNCF-conformant, RKE2 and Rancher included.
Supported Ecosystem
What we cover
From initial cluster setup to production optimisation — the same engineer who builds it also trains your team on how to maintain it. Knowledge transfer is a mandatory deliverable, not an optional add-on.
Cluster Architecture Design
Single-tenant, multi-tenant, bare-metal, and managed (EKS/GKE/AKS) — evaluate the tradeoffs and design an architecture that fits your team and workload.
RBAC and Namespace Management
Role-based access control configuration; namespace isolation per team or project, and policy enforcement to prevent privilege escalation.
Helm Chart Development
Per-application Helm charts, values management across environments, OCI Helm registry, and semantic versioning.
Zero-Downtime Upgrade Strategy
Kubernetes minor/patch upgrade planning: drain workers first, validate compatibility, PDB-protected — no uncontrolled restarts in production.
GitOps with ArgoCD / Flux
Bind cluster state to Git. Every change is tracked, auditable, and reversible. ArgoCD or Flux — whichever fits your workflow.
Cluster Security Hardening
CIS Kubernetes Benchmark remediation: API server flags, etcd encryption, kubelet security settings — hardened by default.
Migration Roadmap
From VM monolith to CNCF-conformant HA cluster — every phase documented, reversible, and understood by your team.
- 1
Infrastructure Audit
Analyse current VM and container workloads. Inventory, dependency map, and migration risk assessment — documented before writing a single config file.
- 2
Cluster Design
HA multi-master architecture, network policy, RBAC, and IaC (Terraform/Ansible) plan. Every decision is recorded and justified.
- 3
Zero-Downtime Migration
Canary or blue-green migration strategy. RKE2/Helm installation with ArgoCD-driven GitOps synchronisation from day one.
- 4
Day-2 Operations Handover
HPA configuration, upgrade runbook, DR test results, and Grafana dashboards transferred to your team with a live walkthrough.
VM Monolith → Enterprise Kubernetes
How the manual-intervention burden and reliability problems of traditional infrastructure disappear with production-grade Kubernetes.
Production reference: Teknosa A.Ş. — Rancher RKE2 multi-cluster deployment and management across dev / uat / prod / dr environments. Failover time reduced from 12 minutes to < 30 seconds.
Kubernetes Resource Management
We configure CPU and memory settings to best-practice standards so applications use cluster resources efficiently, predictably, and safely. Throttling and OOMKills get resolved before they reach production.
Requests & Limits
Right-sizing CPU and memory per container. Insufficient requests cause scheduling failures; oversized limits cause OOMKills. We find the right values from real usage data.
HPA Configuration
Horizontal Pod Autoscaler based on CPU/memory or custom metrics (KEDA or Prometheus Adapter). Scale-down policies included to prevent thrashing.
VPA for Automatic Sizing
Run Vertical Pod Autoscaler in Recommendation mode to surface actual usage vs. configured limits — no guessing required.
ResourceQuota and LimitRange
Per-team CPU/memory/pod quotas; namespace-level defaults to prevent unconfigured containers from consuming cluster resources.
Pod Disruption Budget
PDB definitions to guarantee application availability during node maintenance, cluster upgrades, and voluntary disruptions.
CPU Throttling Detection
Identify throttling hotspots via container_cpu_throttled_seconds_total metrics. Optimise limit-to-request ratios to eliminate unnecessary throttling.
Rancher & RKE2 Expertise
When managed cloud Kubernetes isn't the right fit — production-grade cluster deployment and centralised management with the Rancher ecosystem. Fleet GitOps, CIS Benchmark hardening, and multi-cluster oversight from a single control plane.
RKE2 Cluster Deployment
FIPS 140-2 compliantProduction-grade cluster on bare-metal or VMs from scratch: control plane + worker nodes, with CIS hardening profile applied by default.
Rancher Management Server
SSO integrationRancher UI setup, user/project/policy management, and SSO integration for centralised access control across all clusters.
Multi-Cluster Management
Fleet GitOpsManage multiple downstream clusters from a single Rancher instance. Centralised access control, monitoring, and Fleet GitOps.
CIS Hardening
CIS BenchmarkCIS Benchmark profiles, audit log configuration, and security hardening — leveraging RKE2's native security features.
Technologies
Who is this for?
Teams migrating to Kubernetes for the first time, teams wanting to deploy on-premise with RKE2, and engineering teams looking to centrally manage multiple clusters with Rancher. Also for teams hitting recurring OOMKills, CPU throttling, or unstable deployments in production who need root-cause analysis and a lasting fix.
