feat: ship Plinth substrate Helm chart v0.1.0 (walking skeleton)#1
Merged
Conversation
Umbrella chart that bootstraps a minimal Plinth substrate on Kubernetes.
Composes three upstream sub-charts at pinned minor versions:
- cnpg/cloudnative-pg @ 0.28.0 (Postgres operator + Cluster CR)
- cerbos/cerbos @ 0.52.1 (authorisation PDP)
- open-telemetry/opentelemetry-collector @ 0.153.0 (traces/metrics/logs)
The umbrella adds two Plinth-specific templates: a CloudNativePG Cluster
CR (bootstrapped database + owner role) and a `plinth-cerbos-policies`
ConfigMap with a default "items" resource policy mounted into the
Cerbos pod.
Profiles:
- dev (shipped): single node, no HA, low resource floors for
kind/minikube. helm install plinth . -f values/dev.values.yaml
brings up a working substrate.
- staging / prod: stub values files with comments describing the
intended shape; actual values land in subsequent chart versions.
CI: helm dependency build + helm lint + helm template (defaults +
dev profile) + smoke checks asserting the expected kinds (Cluster,
ConfigMap plinth-cerbos-policies, Deployment, CRDs) are rendered.
Roadmap (deferred, called out in README): Vault, Authentik, MinIO,
NATS, Redis, OpenSearch, SigNoz, Wazuh, Falco, Trivy, Kyverno,
Argo CD, Argo Rollouts, Backstage, kube-prometheus-stack. Plus
Talos cluster bootstrap and OCI publish to ghcr.io/plinth-dev/platform.
