We seek an experienced professional to design and enhance our Kubernetes-native automation OCAS (Operator-based Cloud Automation Solution) for the Telekom Cloud environment. OCAS delivers fully declarative lifecycle management (deploy configure update teardown) for containerized applications/CNFs using CRDs controllers and GitOps with FluxCD. Integrations include Vault/ESO Kafka Logging Operator Telegraf GitLab/Artifactory.
Scope of Work
In general the scope of work is the creation of solution and functional concepts based on the proposed solutions and project orders as of: Basic functionalities required models interface design migration concept evasion and relapse scenarios and in more detail:
- Design, implement and test production‑grade Kubernetes operators (Go controllerruntime/Kubebuilder or Operator SDK) with tested CRDs: CNF LCM Operator, Service LCM Operator, Infrastructure Provisioning Operator, Test‑Automation‑Framework handler, Helm CNF Operator/Wrapper.
- Define reconciliation logic status/events finalizers; implement idempotent resilient controllers for the targeted solution.
- Design, implement and test production‑grade Kubernetes operators (Go controllerruntime/Kubebuilder or Operator SDK) with tested CRDs.
- Design, implement and test Configuration‑as‑Data: templates environment-specific rendering and Git‑based workflows. Design, implement and test working integrations with Kafka Logging Operator Telegraf.
- Create build and test shared parameter models (customer profile) and config builders for cross‑operator parameter injection. Create and optimize GitOps repositories with FluxCD (multi‑env/multi‑cluster) with release templates, Helm/Kustomize overlays, release definitions and inventory CRDs.
- Specify, develop and test a fully automated CNF lifecycle including in‑service upgrades, dependency management (blocking/non‑blocking), scaling and clean teardown.
- Observability by design: logs, events, metrics, error handling, retry/backoff.
- Develop, implement and test Security & compliance integration: RBAC, Vault/ESO secret handling, image/chart provenance (Artifactory) policy alignment.
- Implement project‑specific CI/CD pipelines (GitLab) for build, test, security scanning and release to Artifactory.
- Create detailed architecture and design documentation and technical descriptions of the target solutions (e.g. detailed concepts, APIs, runbooks, application documents, initial user manuals).
