# Minimal single-tenant SandboxTemplate for DeepSeek Harness Web.
#
# This is the "just one DSH Web" quick-start template. For the full
# multi-tenant platform (warm pool, per-user claims, gateway, idle-suspend),
# see examples/dsh-agents-as-a-service/.
#
# Prerequisites (create these first, or apply 00-prereqs.yaml from the
# examples directory):
#   - Namespace dsh-demo.
#   - Secret dsh-provider-keys in dsh-demo with key DEEPSEEK_API_KEY
#     (injected via envFrom; the pod starts without it, only model calls fail).
# The agent-sandbox controller (v1.0.7, API v1beta1) must be installed.
