Expected Behaviors
Fundamental Awareness
Works alongside a Kubernetes team and recognizes Helm as the package manager that replaces hand-managed manifests. Identifies charts, releases, and repositories at a conceptual level, and can set up the local CLI toolchain on a workstation. Reads a chart directory, points out templating delimiters, and understands that subcharts and hooks exist to compose applications and react to lifecycle events, though hands-on actions remain guided by more senior engineers.
Novice
Operates on development clusters performing routine chart consumption tasks. Adds public repositories, searches for charts, and installs or uninstalls releases into specific namespaces. Authors basic values files, renders manifests with helm template, and uses conditionals, ranges, and pipelines for simple customizations. Declares chart dependencies, runs dependency updates, accesses bundled files, and applies pre/post-install hook annotations with weights under supervision.
Intermediate
Owns release workflows for one or more services across environments. Customizes values with proper override precedence, packages and publishes charts to HTTP or OCI registries, and drives upgrade, rollback, and stuck-release diagnostics. Authors named templates, helpers, NOTES.txt, and values.schema.json validation. Manages subchart overrides, global values, and conditional enablement, and designs job-based migration hooks with deletion policies and failure handling.
Advanced
Designs chart architectures for complex platforms and CI/CD pipelines. Hardens templates with required, fail, tpl, and JSON schema validation to prevent silent failures. Architects subchart composition with aliasing, import maps, and selective transitive overrides, and coordinates global values across trees. Engineers atomic upgrades, drift reconciliation, signed chart distribution, and private registry access. Orchestrates hook-driven migrations while mitigating race conditions and ordering hazards.
Expert
Sets organizational standards for Helm across the enterprise. Defines library chart architectures, linting rules, API compatibility contracts, and supply chain security for chart artifacts. Architects umbrella charts and multi-environment promotion topologies integrated with GitOps and policy engines. Governs lifecycle contracts between dependent charts, deterministic hook ordering for stateful migrations, rendering performance, and reusable validation frameworks adopted across platform teams.
