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, controller-runtime/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 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).
