kubernetes-sigs/agent-sandbox

Agent Sandbox is an official Kubernetes SIG Apps project shipping a `Sandbox` CRD and controller for managing isolated, stateful, singleton workloads with stable identity and persistent storage — built specifically for AI agent runtimes. 2.9k stars, Apache-2.0, Go, extends Kubernetes with SandboxTemplate, SandboxClaim, and SandboxWarmPool CRDs that mirror how AI workloads actually use sandboxes.

Why it matters

Useful for platform and infra teams running AI agent workloads on Kubernetes who need a first-class, SIG-grade API for managing per-session sandbox pods with warm pools, lifecycle control, and stable identity — instead of hand-rolling StatefulSets or Deployments per session.

Who should use it

Who should skip it

Skip if the source link, docs, or setup requirements do not match your workflow.

Risk explanation

CRD is at an early KEP stage — schema may evolve before 1.0, plan for upgrade work; Best for teams already running Kubernetes — not a standalone sandbox solution like cycle-24 OpenSandbox.
