Kubernetes Deployment and Application Operations

Kubernetes manages the execution and configuration of containerised applications. It becomes useful when a product has multiple components, separate environments and controlled release requirements. We assess the need for orchestration against architecture, workload and the team's operational capacity.

DELIN as a practical example

The production configuration of the DELIN platform uses Kubernetes through K3s and Flux. Docker builds the container images, while web, API, worker and marketing have separate roles. This separates the public site from the working application and background processing, with deployment configuration kept under version control.

Typical scope

• Mapping application components, environments and dependencies.

• Configuring containers, network routes and access boundaries.

• Readiness checks, resource controls and release procedures.

• Planning logs, operational visibility and recovery paths.

Reliability needs verification

A cluster alone does not guarantee uninterrupted service. Storage, backups, migrations, rollback procedures and responsibility for external services need explicit decisions. Release preparation should verify application behaviour during restarts, dependency failures and configuration changes.

How we estimate the work

Scope depends on the number of components, existing infrastructure, environment requirements and release process. A simpler deployment model may be more appropriate for a small website. We begin with an architecture review or technical audit, then agree on deliverables and the required level of operational support.
