Epic 16 — R1 Federation Helm Chart

[fupelaqu]

Tracking issue for the R1 Federation Helm Chart, migrated from the private softclient4es-arrow repo into this dedicated, customer-facing chart repo. The chart lives at softclient4es-federation/ (no helm/ prefix) and is reconstructed as a stacked chain of per-story branches off main.

Stories (this repo)

Story	Title	Issue	PR	Branch (base)
16.1	Helm chart skeleton + federation Deployment	#1	#2	feature/16.1 (main)
16.2	Per-ES-version sidecar packaging	#3	#4	feature/16.2 (feature/16.1)
16.3	Kubernetes Secrets, TLS, ESO compatibility	#5	#6	feature/16.3 (feature/16.2)
16.4	Topology examples	#7	#8	feature/16.4 (feature/16.3)
16.5	helm test smoke + comprehensive CI/CD	#9	#10	feature/16.5 (feature/16.4)
16.6	Operator guide	#12	#13	feature/16.6 (feature/16.5)

Notes

• Stacked chain off main: each story branches from the previous one.
• Images come from public DockerHub: docker.io/softnetwork/softclient4es-federation and docker.io/softnetwork/softclient4es{6,7,8,9}-arrow-flight-sql. The federation image is packaged from the private softclient4es-arrow source (a separate, build-side concern handled in that repo); this chart only references the published public images.
• The chart is the customer-facing artifact; it never builds images and renders ZERO kind: Secret.
• The only runtime gate is the license maxClusters quota: Community = 1, Pro = 5, Enterprise = unlimited. Single-cluster federation is free (Community); 2+ sidecars require Pro/Enterprise.
• OQ-1: the federation + sidecar DockerHub images are not yet published; CI's live kind-install jobs probe image availability and skip-with-warning until publication. This is a release follow-up.
