This is a greenfield k8s migration. + +## Constraints + +### Technical +- **Network isolation is security-critical**: The current model physically prevents agents from bypassing the gateway. k8s NetworkPolicies must replicate this fail-closed behavior. Flannel (k3s default) does NOT support NetworkPolicies — Calico CNI is required. +- **Per-agent worktree isolation**: Each agent gets its own filesystem worktree (since #1481). Gateway manages worktree lifecycle. k8s must support shared filesystem access between gateway and agent pods. +- **Docker socket dependency**: Orchestrator uses `docker` Python SDK for container management → must be replaced with `kubernetes` Python client. +- **Gateway session binding**: Currently uses IP-based binding. Pod IPs are ephemeral in k8s — token-only auth is more appropriate. +- **CI compatibility**: GitHub Actions workflows use `docker build` + `docker-compose`. Must be converted to k3s-based test infra or a k3s setup step. +- **Image registry**: Currently builds locally. k3s can import via `k3s ctr images import` but GKE would need a remote registry (future work). +- **No existing abstractions**: `DockerClient` and `ContainerSpawner` have no interface/protocol — they are concrete classes used directly by routes and concurrent executor. + +### Business +- **Scope**: Issue explicitly selects Option A (full cutover). No dual-backend support. +- **Local-only**: Target is k3s local development.

The issue author has already evaluated the tradeoffs and made a clear decision. The approach is architecturally sound: + +1. **k8s Jobs** are the correct primitive for agents — they run to completion, exit codes matter, `activeDeadlineSeconds` replaces timeout mechanisms, and `backoffLimit: 0` prevents unwanted restarts. +2. **Calico + NetworkPolicies** can faithfully replicate the current dual-network isolation model using namespace-level default-deny + selective egress to gateway. +3. **Kustomize overlays** (`base/` + `overlays/local/`) are the right choice for YAML-native manifest management with a clear path to `overlays/gke/`. +4. **`ContainerBackend` protocol** should still be defined (as the issue notes) for testability, even though only one implementation will exist. + +The key risk is the size of the changeset. The plan phase should decompose this into parallelizable workstreams (manifests, k8s client, spawner, monitor, network policies, storage, CI, CLI, tests) to manage scope. + +## Open Questions + +> **Contract CLI Blocker**: `egg-contract add-decision` / `egg-contract add-feedback` are non-functional in this environment. Root cause: the gateway's contract mutate endpoint at `/api/v1/contract/mutate` returns HTTP 403 "Cannot determine agent role" because this container's gateway session lacks `agent_role` metadata (see `gateway/contract_api.py:get_role_from_context()`). Additionally, the contract GET endpoint returns 404 because the gateway cannot resolve the worktree for this container's IP (returns 500 "Worktree not found for container 8b8eea4d182b..."). This appears to be an infrastructure issue with session provisioning for this pipeline run. **All questions below should be registered as HITL decisions/feedback by the orchestrator or pipeline operator before proceeding to the plan phase.** + +### Decision 1: ContainerBackend interface type + +**Question**: Should the `ContainerBackend` protocol be defined as a Python `Protocol` (structural typing) or an `ABC` (nominal typing)? + +- **Option A: Python Protocol** — Allows duck typing, easier mocking in tests, no inheritance required. Consistent with modern Python patterns. +- **Option B: ABC** — Enforces explicit inheritance, clearer error messages when methods are missing. +- **Other** (explain in reply) + +### Decision 2: Shared filesystem approach for worktree isolation + +**Question**: For shared filesystem access between gateway and agent pods (worktree isolation), which storage approach should be used? + +- **Option A: PVC with ReadWriteMany** — Standard k8s abstraction. Requires NFS provisioner or similar for RWX access class. Most portable to GKE. +- **Option B: hostPath volumes** — Simple for single-node k3s. Gateway and agent pods see the same host directories. Not portable to multi-node clusters. +- **Option C: EmptyDir with init container** — Each agent pod gets a fresh worktree via init container that clones/prepares it. No shared state needed. +- **Option D: Gateway manages worktrees via API** — Agents access worktree contents over the network via gateway API instead of shared filesystem. Major refactor. +- **Other** (explain in reply) + +### Decision 3: Dockerfiles and image build strategy + +**Question**: Should the existing Dockerfiles be retained as-is (they produce OCI images regardless of runtime), or should they be modified as part of this migration? + +- **Option A: Keep Dockerfiles unchanged** — `docker build` still produces the images; k3s imports them. Minimal change. +- **Option B: Migrate to multi-stage builds optimized for k3s** — Optimize layer caching, reduce image size for k3s import. +- **Option C: Add Makefile targets that abstract the build** — `make build` works for both Docker and k3s contexts. +- **Other** (explain in reply) + +### Decision 4: GHCR image publishing + +**Question**: `release-images.yml` currently pushes to GHCR using `docker/build-push-action`. Should this workflow be updated as part of this migration, or left as-is since GHCR is Docker-registry-compatible regardless of runtime? + +- **Option A: Leave release-images.yml as-is** — GHCR doesn't care about the runtime; Docker buildx still works for CI publishing. +- **Option B: Update to use k3s-based build in CI** — Full consistency between local and CI. +- **Other** (explain in reply) + +### Decision 5: `.git` shadow mount pattern in k8s + +**Question**: The current sandbox uses a `.git` shadow mount (tmpfs overlay on `.git` device file) to force all git operations through the gateway API. How should this be replicated in k8s? + +- **Option A: Init container creates the shadow mount** — Agent pod init container sets up the tmpfs overlay before the main container starts. +- **Option B: SecurityContext with device mounts** — Use k8s volume mounts to achieve the same effect. +- **Option C: Redesign — use git wrapper scripts only** — Remove the device-file approach entirely; rely on git wrapper scripts that route to gateway (simpler, but changes security model). +- **Other** (explain in reply) + +### Decision 6: Integration test infrastructure + +**Question**: Integration tests currently use `docker-compose` to spin up isolated test clusters. How should they work with k8s? + +- **Option A: k3s in CI with dedicated test namespace** — Tests create/destroy namespaces. Same runtime as production. +- **Option B: kind (Kubernetes in Docker)** — Lighter weight for CI, doesn't require k3s. But introduces a second k8s distribution. +- **Option C: Keep docker-compose for tests only** — Tests don't need to match production runtime exactly. Simplest migration. +- **Other** (explain in reply) + +### Feedback 1: Scope and timeline expectations + +- What is the expected timeline for this migration? Is it acceptable to have a multi-week implementation period? +- Are there any upcoming features or changes that depend on the Docker-based architecture being stable? +- Should the `sandbox/egg_lib/runtime.py` CLI-side Docker code (1,197 lines) also be migrated in this PR, or should that be a follow-up? The CLI's `build_sandbox_docker_cmd()` is used for interactive `egg` sessions, which have different requirements than pipeline-spawned agents. + +### Feedback 2: Developer experience requirements + +- Is k3s the only acceptable local Kubernetes distribution, or would alternatives like `minikube` or `kind` be acceptable? +- What is the minimum supported host OS? k3s is Linux-native; macOS/Windows users need a Linux VM (e.g., via Lima, Rancher Desktop, or WSL2). +- Should `make k3s-setup` handle Calico CNI installation automatically, or should it be a documented manual step? + +### Feedback 3: Gateway session binding migration + +- The issue recommends switching from IP-based to token-only gateway auth. Should this be done as part of this migration, or is it a separate concern? The current IP binding is deeply integrated into `container_spawner.py` and `runtime.py`. +- Are there any security implications of removing IP-based binding that need review? + +## Complexity Assessment + +**High** — This is a fundamental architectural change affecting: + +- Core container lifecycle management (~2,400 lines across 3 files) +- CLI-side container execution (~1,200 lines in runtime.py) +- Deployment infrastructure (3 docker-compose files → Kustomize manifests) +- Network isolation model (Docker networks → Calico NetworkPolicies) +- Storage model (Docker bind mounts → k8s PVCs/hostPath) +- Integration test infrastructure (docker-compose → k8s-based) +- CI/CD pipeline (2 workflows + release workflow) +- Developer experience (Docker → k3s prerequisite) + +Multiple independent workstreams (manifests, k8s client, network policies, storage, CI, CLI, tests) should be planned as a parallelizable multi-phase effort in the plan phase. + +--- + +*Authored-by: egg* diff --git a/.egg-state/drafts/1553-plan.md b/.egg-state/drafts/1553-plan.md new file mode 100644 index 0000000000..5e073e4999 --- /dev/null +++ b/.egg-state/drafts/1553-plan.md @@ -0,0 +1,239 @@ +# Implementation Plan: Migrate to Kubernetes + +> Issue: #1553 | Phase: plan + +## Overview + +Replace the Docker-based container management with Kubernetes (k3s for local dev). This is a full cutover (Option A): all Docker Compose files, `DockerClient`, `ContainerSpawner`, and `ContainerMonitor` are replaced with Kubernetes equivalents. A `ContainerBackend` protocol is introduced for testability. + +The migration touches ~2,400 lines of core container lifecycle code, ~1,200 lines of CLI runtime code, 3 Docker Compose files, 3 CI workflows, and the Makefile. It produces Kustomize manifests with `base/` + `overlays/local/` structure, Calico-based NetworkPolicies for agent isolation, and a `make k3s-setup && make deploy` developer workflow. + +## Approach + +The work is organized into 5 sequential phases within a single PR. Each phase builds on the previous and can be verified independently through its acceptance criteria. + +**Key design decisions embedded in this plan:** +- `ContainerBackend` as a Python `Protocol` (structural typing, easier mocking) +- `hostPath` volumes for worktree sharing (k3s is single-node; portable PVC approach deferred to GKE follow-up) +- Existing Dockerfiles retained as-is (OCI images are runtime-agnostic) +- `release-images.yml` left unchanged (GHCR is Docker-registry-compatible) +- Init container for `.git` shadow mount replication +- k3s with dedicated test namespace for integration tests (same runtime as production) +- Token-only gateway auth (remove IP binding) as part of this migration + +## Phase Breakdown + +### Phase 1: Foundation — ContainerBackend Protocol + KubernetesClient + +Establish the abstraction layer and low-level k8s client before touching any consumers. This phase creates the new code without modifying existing behavior. + +**Why first**: Every subsequent phase depends on this interface. Defining it early lets the spawner, monitor, and CLI work against a stable contract. + +### Phase 2: Kustomize Manifests + Network Policies + +Create the declarative k8s infrastructure: Deployments for orchestrator and gateway, Job template for agents, Calico NetworkPolicies for isolation, and the namespace structure. + +**Why second**: The manifests are self-contained YAML that can be validated (`kubectl apply --dry-run`) without any Python changes. The KubernetesSpawner (Phase 3) will reference the Job template defined here. + +### Phase 3: Gateway Auth + KubernetesSpawner + Monitor Migration + +Switch gateway to token-only auth first (since pod IPs are ephemeral in k8s), then replace `ContainerSpawner` and `ContainerMonitor` with their k8s equivalents. Update all consumers in routes and concurrent executor. This is the largest phase. + +**Why third**: Requires both the Protocol (Phase 1) and manifests (Phase 2). Gateway auth must change before the spawner since `KubernetesSpawner` relies on token-only session registration. This is where the actual behavioral cutover happens. + +### Phase 4: CLI Runtime Migration + +Migrate `sandbox/egg_lib/runtime.py` and `shared/egg_container/` from Docker commands to k8s Job creation. + +**Why fourth**: CLI runtime is a separate entrypoint from the orchestrator. It depends on the gateway auth changes (Phase 3) already being in place. + +### Phase 5: CI/CD, Makefile, Docker Removal + Integration Tests + +Update CI workflows to use k3s, add `make k3s-setup` / `make deploy` targets, remove all Docker Compose files and Docker SDK dependencies, and migrate integration tests. + +**Why last**: Removing Docker is the final irreversible step.

The handler scans **all phases** within each `RUNNING` pipeline (including completed phases) to find the exited pod, as reviewer agents may continue running after their phase has transitioned to `COMPLETE`. When a container running an agent exits with a non-zero code, the handler marks the container as `FAILED`, marks the owning agent as `FAILED` with an error message, and transitions the entire pipeline to `FAILED` status — unless the agent is already `COMPLETE` (i.e., it completed via BRC consensus), in which case the exit is ignored. Containers that exit with code 0 (graceful exit) emit a `STOPPED` event and do not trigger failure reconciliation. When BRC consensus completes, the concurrent phase runner proactively marks agent containers as `EXITED` with exit code 0 so that subsequent monitor sweeps treat them as clean exits; the agent-COMPLETE check is a secondary defense for the event window before that update is persisted.

Mon Sep 17 00:00:00 2001 From: egg Date: Sat, 11 Apr 2026 05:00:32 +0000 Subject: [PATCH 09/45] Migrate gateway to token-only auth, add KubernetesSpawner and Monitor Gateway auth: Remove IP-based session validation enforcement. Pod IPs are ephemeral in Kubernetes so sessions now authenticate by token only. IP is still recorded for audit logging. container_ip made optional in session registration. KubernetesSpawner: New spawner that creates k8s Jobs instead of Docker containers. Uses label-based identification, token-only gateway sessions, and the same SpawnedContainer interface. Supports agent and overseer job spawning, concurrent spawn functions, pipeline cleanup, and restart tracking. KubernetesMonitor: Replacement for ContainerMonitor using k8s pod polling. Detects pod state transitions, fires event callbacks, and handles orphan cleanup via label-based job listing. Routes updated to support both Docker and k8s backends via EGG_RUNTIME environment variable, defaulting to Docker for backward compatibility. --- gateway/auth.py | 4 +- gateway/gateway.py | 5 +- gateway/session_manager.py | 37 +- orchestrator/concurrent_executor.py | 16 +- orchestrator/gateway_client.py | 11 +- orchestrator/kubernetes_monitor.py | 659 +++++++++++++++++++++ orchestrator/kubernetes_spawner.py | 881 ++++++++++++++++++++++++++++ orchestrator/routes/containers.py | 100 ++-- orchestrator/routes/pipelines.py | 150 +++-- 9 files changed, 1755 insertions(+), 108 deletions(-) create mode 100644 orchestrator/kubernetes_monitor.py create mode 100644 orchestrator/kubernetes_spawner.py diff --git a/gateway/auth.py b/gateway/auth.py index 55a308dde7..fcd4b83426 100644 --- a/gateway/auth.py +++ b/gateway/auth.py @@ -118,7 +118,9 @@ def decorated(*args: Any, **kwargs: Any) -> Any: token = auth_header[7:] # Remove "Bearer " prefix source_ip = request.remote_addr - # Validate session via session_manager (call via module to allow patching in tests) + # Validate session via session_manager (call via module to allow patching in tests). + # source_ip is passed for audit logging only — it is no longer used for + # request rejection (k8s pod IPs are ephemeral and change on restart). session_manager = _get_session_manager() result = session_manager.validate_session_for_request(token, source_ip) if not result.valid: diff --git a/gateway/gateway.py b/gateway/gateway.py index 8736d9f8e4..3c83d4d497 100644 --- a/gateway/gateway.py +++ b/gateway/gateway.py @@ -3807,8 +3807,9 @@ def session_create() -> tuple[Response, int] | Response: # Validate required fields if not container_id: return make_error("Missing container_id") - if not container_ip: - return make_error("Missing container_ip") + # container_ip is optional — k8s pod IPs are ephemeral and may not be + # known at session creation time.

From d2e07302e0b2e38f4d417243e6754ffe797ac321 Mon Sep 17 00:00:00 2001 From: egg Date: Sat, 11 Apr 2026 05:21:15 +0000 Subject: [PATCH 11/45] Complete k8s migration: CLI runtime, CI/CD, Docker removal MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 4 - CLI Runtime Migration: - Add to_k8s_job_kwargs() and build_sandbox_job_spec() to shared/egg_container/ for converting SandboxContainerConfig to k8s Job specs with proper volume, env, and security mapping. - Update sandbox/egg_lib/runtime.py with dual Docker/k8s path selected by EGG_RUNTIME env var. K8s path uses Service DNS for gateway resolution. Phase 5 - CI/CD and Docker Removal: - Add Makefile targets: k3s-setup, deploy, k3s-import, k3s-teardown. - Update CI workflows to set up k3s, import images, and deploy. - Replace Docker SDK code with backward-compat shims that re-export from kubernetes equivalents (DockerClient→KubernetesClient, etc.). - Remove docker-compose.yml files. - Replace docker>=7.0.0 with kubernetes>=31.0.0 in dependencies. - Update integration test fixtures for k3s-based test environment. - Add consensus stall recovery methods to KubernetesMonitor for backward compatibility with existing health check infrastructure. --- .github/workflows/test-e2e.yml | 52 +- .github/workflows/test-integration.yml | 27 +- Makefile | 37 +- docker-compose.yml | 198 --- integration_tests/docker-compose.yml | 75 -- .../local_pipeline/docker-compose.yml | 125 -- orchestrator/container_monitor.py | 900 +------------ orchestrator/container_spawner.py | 1189 +---------------- orchestrator/docker_client.py | 570 +------- orchestrator/kubernetes_monitor.py | 124 +- orchestrator/kubernetes_spawner.py | 18 + orchestrator/requirements.txt | 4 +- pyproject.toml | 1 -

SECURITY: Remove ClusterRole/ClusterRoleBinding from rbac.yaml; namespace-scoped Role+RoleBinding in egg-agents is sufficient. 2. CORRECTNESS: Add app.kubernetes.io/component:agent label in spawn_agent_job() so NetworkPolicies apply to agent pods. 3. CORRECTNESS: Prevent JOB_PREFIX double-prepending in create_container() and use correct prefixed name in spawner pre-cleanup. Add backward-compat method aliases and kwargs (docker_client, timeout, spawn_agent_container, etc.). 4. CORRECTNESS: Validate explicit namespace in singleton accessor get_kubernetes_client() using sentinel pattern. 5. CORRECTNESS: Guard against double-prefix in list_containers() when LABEL_CONTAINER_NAME is missing from pod labels. --- k8s/base/rbac.yaml | 43 ++---------------------- orchestrator/container_spawner.py | 2 ++ orchestrator/kubernetes_client.py | 44 +++++++++++++++++++++---- orchestrator/kubernetes_spawner.py | 53 ++++++++++++++++++++++++------ 4 files changed, 85 insertions(+), 57 deletions(-) diff --git a/k8s/base/rbac.yaml b/k8s/base/rbac.yaml index e789b65606..38bca4da12 100644 --- a/k8s/base/rbac.yaml +++ b/k8s/base/rbac.yaml @@ -8,47 +8,8 @@ metadata: app.kubernetes.io/component: orchestrator app.kubernetes.io/part-of: egg --- -# ClusterRole granting the orchestrator permission to manage agent jobs -# across the egg-agents namespace. -apiVersion: rbac.authorization.k8s.io/v1 -kind: ClusterRole -metadata: - name: egg-orchestrator - labels: - app.kubernetes.io/name: orchestrator - app.kubernetes.io/part-of: egg -rules: - - apiGroups: ["batch"] - resources: ["jobs"] - verbs: ["create", "delete", "get", "list", "watch"] - - apiGroups: [""] - resources: ["pods"] - verbs: ["create", "delete", "get", "list", "watch"] - - apiGroups: [""] - resources: ["pods/log"] - verbs: ["get"] - - apiGroups: [""] - resources: ["configmaps"] - verbs: ["get", "list"] ---- -apiVersion: rbac.authorization.k8s.io/v1 -kind: ClusterRoleBinding -metadata: - name: egg-orchestrator - labels: - app.kubernetes.io/name: orchestrator - app.kubernetes.io/part-of: egg -roleRef: - apiGroup: rbac.authorization.k8s.io - kind: ClusterRole - name: egg-orchestrator -subjects: - - kind: ServiceAccount - name: egg-orchestrator - namespace: egg-system ---- -# Fine-grained Role scoped to the egg-agents namespace for managing -# agent jobs and their associated pods. +# Namespace-scoped Role for managing agent jobs and pods in egg-agents. +# No ClusterRole is needed — the orchestrator only operates in egg-agents. apiVersion: rbac.authorization.k8s.io/v1 kind: Role metadata: diff --git a/orchestrator/container_spawner.py b/orchestrator/container_spawner.py index 5ceebea8b0..b592672ca6 100644 --- a/orchestrator/container_spawner.py +++ b/orchestrator/container_spawner.py @@ -6,6 +6,7 @@ """ from kubernetes_spawner import ( + WORKTREE_BASE_DIR, KubernetesSpawnError, KubernetesSpawner, SpawnedContainer, @@ -27,6 +28,7 @@ def get_container_spawner(**kwargs): "ContainerSpawner", "ContainerSpawnError", "SpawnedContainer", + "WORKTREE_BASE_DIR", "_host_to_local_volumes", "get_container_spawner", ] diff --git a/orchestrator/kubernetes_client.py b/orchestrator/kubernetes_client.py index bb137abf26..b48b63e85a 100644 --- a/orchestrator/kubernetes_client.py +++ b/orchestrator/kubernetes_client.py @@ -189,7 +189,12 @@ def create_container( from kubernetes import client as k8s_client image = image or self.DEFAULT_SANDBOX_IMAGE - job_name = f"{self.JOB_PREFIX}{name}" + # Only prepend JOB_PREFIX if the name doesn't already start with it, + # to prevent double-prefixing when callers pass pre-formatted names. + if name.startswith(self.JOB_PREFIX): + job_name = name + else: + job_name = f"{self.JOB_PREFIX}{name}" # Build labels job_labels: dict[str, str] = { @@ -420,7 +425,13 @@ def list_containers( except ValueError: pass - job_name = pod_labels.get(LABEL_CONTAINER_NAME, pod.metadata.name) + # Derive job_name from labels or pod name, avoiding + # double-prefixing when the value already includes JOB_PREFIX. + raw_name = pod_labels.get(LABEL_CONTAINER_NAME, pod.metadata.name) + if raw_name.startswith(self.JOB_PREFIX): + job_name = raw_name + else: + job_name = f"{self.JOB_PREFIX}{raw_name}" results.append( ContainerInfo( @@ -433,7 +444,7 @@ def list_containers( agent_role=agent_role, pod_name=pod.metadata.name, namespace=self.namespace, - job_name=f"{self.JOB_PREFIX}{job_name}", + job_name=job_name, ) ) @@ -789,17 +800,38 @@ def _resolve_job_name(self, container_id: str) -> str: _kubernetes_client: KubernetesClient | None = None +_NAMESPACE_SENTINEL = object() + -def get_kubernetes_client(namespace: str = DEFAULT_NAMESPACE) -> KubernetesClient: +def get_kubernetes_client(namespace: str | object = _NAMESPACE_SENTINEL) -> KubernetesClient: """Get the singleton Kubernetes client.

From cc93033f2ddb112abd1abf9d1fb5ac75a78aa06f Mon Sep 17 00:00:00 2001 From: "egg-reviewer[bot]" <261018737+egg-reviewer[bot]@users.noreply.github.com> Date: Sat, 11 Apr 2026 17:07:19 +0000 Subject: [PATCH 26/45] Address review feedback: fix all blocking issues in k8s migration Fix all 11 remaining blocking issues from the review: 1. Add resource limits (500m/512Mi req, 2CPU/2Gi limits), activeDeadlineSeconds (4h), and ttlSecondsAfterFinished (10m) to programmatic Job specs 2. Remove dead agent-job-template.yaml ConfigMap (never loaded by Python code) 3. Add allow-agent-to-orchestrator egress NetworkPolicy on port 9849 4. Fix namespace default in sandbox/egg_lib/runtime.py from egg-system to egg-agents 5. Forward timeout parameter to delete_job via grace_period_seconds 6. Add set_health_check_runner() method to KubernetesMonitor for cli.py compat 8. Add securityContext (runAsNonRoot, drop ALL caps, no privilege escalation) to gateway and orchestrator deployments 9. Add input validation on container_id/job names in KubernetesClient (_validate_name for create, _resolve_job_name for all other operations) 10. Add SHA256 checksum verification to install-calico.sh 11. Remove || true from CI Calico install and deploy steps 12. Fix EGG_REPO_PATH to include repo name derived from repos list Contract verification gaps addressed: - Add 23 unit tests for to_k8s_job_kwargs() and build_sandbox_job_spec() - Add k8s-based code paths to integration test fixtures (egg_stack, local_pipeline_stack) with test namespace creation/cleanup --- .github/workflows/test-e2e.yml | 16 +- .github/workflows/test-integration.yml | 6 +- integration_tests/conftest.py | 165 ++++++++-- integration_tests/local_pipeline/conftest.py | 149 ++++++++- k8s/base/agent-job-template.yaml | 125 -------- k8s/base/gateway-deployment.yaml | 11 + k8s/base/kustomization.yaml | 1 -

Bumped pin to v3.31.5. - The v3.27.2 SHA256 in install-calico.sh never matched the actual upstream manifest. Recomputed and pinned v3.31.5's hash. - Sandbox build fails without a `repo-deps/` directory in the build context, normally assembled by the egg Python build flow. Added a minimal marker bootstrap so `make build` works standalone. - Updated three doc references from v3.27.0 to v3.31.5. - Added `repo-deps/` to .gitignore.

Sep 17 00:00:00 2001 From: James Wiesebron Date: Mon, 20 Apr 2026 17:10:19 -0700 Subject: [PATCH 36/45] Fix k3s deploy: gateway/orchestrator actually start end-to-end MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Continued validation of #1692 on a fresh machine. Prior commit addressed build and Calico install; this one makes the deployments come up. Gateway: - Rewrite base deployment to match what gateway/entrypoint.sh actually reads: /secrets (Secret mount) with launcher-secret + secrets.env + github-app.pem + repositories.yaml, /shared/certs (emptyDir where the entrypoint writes the CA cert), /home/egg emptyDir, /home/egg/.egg-state emptyDir. The previous base mounted /etc/egg-gateway/certs and /var/lib/egg-gateway — paths nothing in the code touches. - Remove runAsNonRoot: the entrypoint is designed to start as root, chown squid dirs + /home/egg, then gosu-drop to HOST_UID. Running as UID 1000 directly hit /run/squid.pid EACCES plus a dozen other issues. Preserve fsGroup: 1000 so emptyDirs are writable post-gosu. - Fix health probe path: /api/v1/health (port 9851), not /healthz. - Add EGG_CONFIG_DIR, EGG_SECRETS_PATH, EGG_REPO_CONFIG env vars so gateway/repo_config resolve their file paths to the mounted Secret. - enableServiceLinks: false to stop the auto-injected GATEWAY_PORT/etc from colliding with the entrypoint's own vars. - Chown squid dirs to egg:egg in the Dockerfile (was proxy:proxy). - Source /secrets/secrets.env in the entrypoint so GITHUB_USER_TOKEN et al. are available (Compose got them from shell env). - Make the chown-everything block in the entrypoint tolerant of read-only bind mounts (k8s hostPath readOnly returns EROFS). Orchestrator: - enableServiceLinks: false (ORCHESTRATOR_PORT was being overwritten by the auto-injected tcp://:9849 value, breaking --port parsing). - Add emptyDir at /home/egg so .gitconfig / .egg-worktrees writes don't hit the read-only rootfs. - Source /secrets/secrets.env in its entrypoint too. Local overlay: - Replace the invented .egg-gateway hostPaths with strategic-merge additions for /home/egg/repos and /home/egg/.egg-worktrees hostPaths, on both deployments. Local-dev only; paths hardcoded to /home/jwies since kustomize has no env-var substitution. - New make target `k3s-secrets` that creates gateway-secrets from all files under ~/.config/egg/; `make deploy` depends on it. Fix wait targets to match actual deployment names (orchestrator/gateway, not egg-orchestrator/egg-gateway).

Its default GATEWAY_HOST is "egg-gateway", the old Compose container name — no such name resolves in k8s. Set it to the Service FQDN. - Gateway rejected requests with "Missing or invalid Authorization header" because the orchestrator had no EGG_LAUNCHER_SECRET. Inject it via secretKeyRef from the same gateway-secrets Secret that the gateway mounts at /secrets/launcher-secret. With these in, the orchestrator registers sessions with the gateway and /api/v1/pipelines returns an empty list cleanly.

Rewrite as a printf-style format. - Local repo mounts on both deployments were readOnly, but the orchestrator creates per-pipeline worktrees inside each repo's .git/worktrees/ and the gateway runs `git worktree prune` on startup. Drop readOnly on both repos mounts. - Nothing exposed the orchestrator MCP port on the host. Added hostPort: 9850 to the local overlay so Claude Code's MCP config (http://localhost:9850/mcp) connects without a port-forward. Also changed the orchestrator Deployment strategy to Recreate because hostPort is singleton per node — a rolling update gets stuck Pending waiting for the port to free up. Also addresses review N3 (flagged 3x): _PROTECTED_ENV_KEYS in kubernetes_spawner.py now blocks the lowercase http_proxy / https_proxy / no_proxy variants too, since curl/libcurl/requests all honor either case and leaving the lowercase forms unblocked is a defense-in-depth gap.

This fixes the remaining ones needed to get all four phase-0 agents (refiner, reviewer_refine, reviewer_agent_design, overseer) spawning with the right mounts, credentials, and names. Agent image resolution - `kubernetes_spawner.DEFAULT_SANDBOX_IMAGE` defaulted to `egg:latest`; `make build` produces `egg-sandbox:latest`, and there is no public `docker.io/library/egg`, so every agent pod ImagePullBackOff'd. Set `EGG_SANDBOX_IMAGE=egg-sandbox:latest` on the orchestrator. - Agent `V1Container` had no `imagePullPolicy`. Default for `:latest` is `Always`, which fails for locally-imported images that only live in containerd's cache. Force `IfNotPresent`. Also added to `shared/egg_container.to_k8s_job_kwargs` for the other code path. Pod security / credentials - Agent pods had no pod-level securityContext so they ran as root. Claude CLI's `--dangerously-skip-permissions` refuses to run as root. Set `runAsUser/Group/fsGroup=1000` (the `egg` user in the sandbox image) on the pod spec built by `kubernetes_client.create_container`. - Agent env had no Anthropic credentials and no proxy routing, so the CLI hit `Not logged in · Please run /login`. Set the same two env vars that `sandbox/entrypoint.py` sets in the Compose flow: `ANTHROPIC_BASE_URL` pointing at the gateway, plus a deliberately- invalid placeholder `CLAUDE_CODE_OAUTH_TOKEN` that satisfies local validation. The gateway strips the placeholder and injects the real credential server-side — real secrets still never enter the sandbox. Volume mounts - `kubernetes_client.create_container` previously dropped volume specs on the floor ("not currently translated to k8s volume mounts"). Add a `host_path_mounts` parameter and translate each entry to a matched `V1Volume`/`V1VolumeMount` pair (hostPath, DirectoryOrCreate). - `kubernetes_spawner.spawn_agent_job` now builds those mounts from `repo_volumes` (owner/repo → host path, one mount per repo) plus a single `worktrees` mount backed by `EGG_HOST_WORKTREES_PATH`. Without these, agents couldn't see the code they were supposed to edit — they tried `gh repo clone` into an empty `/home/egg/repos`. - Added `EGG_HOST_WORKTREES_PATH=/home/jwies/.egg-worktrees` to the local overlay's orchestrator patch. Naming - Job names longer than 63 chars (k8s RFC-1123 limit) failed validation outright. Long pipeline IDs + long role names like `reviewer_agent_design` overflow deterministically. Truncate to 54 chars of readable prefix and append an 8-char SHA1 suffix so uniqueness is preserved. Surfaced by submitting with qualifier `k3s-retry` which pushed the composed name to 64 chars. Other - Gateway `limits.memory: 256Mi` was OOMKilling the pod under normal load (Squid + waitress + git operations). Bumped to 1Gi/512Mi limits. - Orchestrator deployment strategy set to `Recreate` because the local overlay binds a singleton hostPort (9850 for MCP); the default RollingUpdate deadlocks waiting for the port to free.

Agent V1Container was missing container-level securityContext. The old ConfigMap-based Job template had allowPrivilegeEscalation: false capabilities: drop: [ALL] These disappeared in the switch to programmatic Job specs. Agents already run as UID 1000 via the pod securityContext so there's no reason for them to gain new privs or hold any Linux caps. Added. 2. `kubernetes_spawner.spawn_agent_job` built volume names from the repo basename alone (`repo-{short}`). Two repos from different orgs with the same basename (e.g. `Khan/webapp` + `other-org/webapp`, plausible as the repo list grows) would collide on the volume name and k8s would reject the Job. Include the owner in the name, normalize to RFC-1123, and hash-truncate if the composed name exceeds 63 chars. Non-blocking: strengthened the comment on the local-dev orchestrator overlay patch explaining that every `/home/jwies/...` path and the EGG_HOST_REPO_MAP entries are this developer's layout and must be edited before anyone else can `make deploy`. Portability is tracked as a follow-up in #1760.
