Shiny and Chrome. ⚡* </div> --- ## What You Get You run Gas Town locally. This operator runs your polecats as Kubernetes pods. Your workflow doesn't change. The `gt` CLI you already use works exactly the same. The operator just gives you more compute - as much as your cluster can handle. | On Your Laptop | With the Operator | |----------------|-------------------| | ~20-30 polecats (CPU bound) | **Hundreds** | | Laptop stays open | **Close your laptop** | | You're online | **Town runs 24/7** | | One machine | **Horizontal scale** | **The unlock:** Queue 50 issues. Dispatch 50 polecats. Close your laptop. Come back to PRs. ```mermaid flowchart TB subgraph Local["Your Laptop (Optional)"] Mayor["🎩 Mayor<br/>Orchestrates"] GT[gt CLI] end subgraph K8s["Kubernetes Cluster"] OP[Gas Town Operator] Witness["👁️ Witness<br/>Monitors health"] Refinery["⚙️ Refinery<br/>Merges PRs"] subgraph Polecats["Polecat Pods"] P1[🦨 furiosa] P2[🦨 nux] P3[🦨 capable] end end subgraph Git["Git Remote"] Repo[(Your Repo)] PRs[Pull Requests] Main[main branch] end Mayor -->|"gt sling"| GT GT -->|"kubectl gt sling"| OP OP -->|spawns| Polecats Witness -->|monitors| Polecats Polecats -->|push branches| Repo Polecats -->|create| PRs Refinery -->|rebase + test| PRs Refinery -->|merge| Main style Local fill:#1a1a2e,color:#fff style K8s fill:#0d47a1,color:#fff style Git fill:#238636,color:#fff ``` **Full Gas Town functionality.** Mayor dispatches work, Witness monitors polecat health, Refinery merges PRs after testing. Same workflow you use locally - the operator just gives you more compute. --- ## What Runs in Your Cluster ### The Operator (1 Pod) The operator is a single deployment that watches for CRs and reconciles them: ``` gastown-system namespace: └── gastown-operator-controller-manager (1 pod, ~64MB memory) └── Watches: Rig, Polecat, Convoy, Witness, Refinery, BeadStore ``` That's it. One small pod runs all the controllers. ### Custom Resources | CR | Scope | What It Does | Creates Pods? | |----|-------|--------------|---------------| | **Rig** | Cluster | Defines a project workspace. Auto-creates Witness + Refinery. | No | | **Polecat** | Namespace | An AI worker. Creates a pod that runs Claude Code. | **Yes** (1 pod per Polecat) | | **Witness** | Namespace | Monitors polecat health. Detects stuck workers, escalates. | No | | **Refinery** | Namespace | Watches for completed polecats (`Available=True`), merges PRs. | No | | **Convoy** | Namespace | Tracks a batch of polecats for parallel execution. | No | | **BeadStore** | Namespace | Optional. Configures beads issue tracking backend. | No | ### What Actually Runs ``` Cluster ├── gastown-system namespace │ ├── gastown-operator-controller-manager ← Always running (1 pod) │ ├── Witness CRs ← Just data, no pods │ ├── Refinery CRs ← Just data, no pods │ └── Polecat CRs ← Each creates a pod ↓ │ ├── polecat-furiosa (pod) ← Running Claude Code │ ├── polecat-nux (pod) ← Running Claude Code │ └── polecat-capable (pod) ← Running Claude Code └── Rig CRs (cluster-scoped) ← Just data, no pods ``` **Key insight:** Only Polecats create pods. Everything else is just Kubernetes custom resources that the operator watches and updates. The Witness and Refinery controllers run inside the operator pod - they don't spawn separate pods. ### Resource Usage | Component | CPU | Memory | Count | |-----------|-----|--------|-------| | Operator | 10m-500m | 64-128MB | 1 | | Polecat pod | 100m-2000m | 512MB-4GB | 0-N (on demand) | --- ### Prerequisites This operator extends Gas Town to Kubernetes. You'll need: 1. **Gas Town installed locally** - The `gt` CLI ([github.com/steveyegge/gastown](https://github.com/steveyegge/gastown)) 2. **Claude Code configured** - `~/.claude/` directory with your settings 3. **A rig initialized** - At least one project workspace in `~/gt/` 4. **Kubernetes cluster** - Any cluster you can deploy to (local or cloud) If you want standalone K8s agents without the Gas Town workflow, see [Advanced: Standalone Mode](#advanced-standalone-mode) below. --- ### Terminology | Term | What It Is | |------|------------| | **Polecat** | An AI worker (runs as a pod) that executes coding tasks | | **Rig** | A project workspace - one repo, many polecats | | **Convoy** | A batch of tasks for parallel execution | | **Beads** | Git-based issue tracker ([separate project](https://github.com/steveyegge/beads)) | --- ## Quick Start ### 1. Install the Operator ```bash helm install gastown-operator oci://ghcr.io/boshu2/charts/gastown-operator \ --version 0.4.2 \ --namespace gastown-system \ --create-namespace ``` ### 2. Install the kubectl Plugin ```bash # Download for your platform (auto-detects OS and architecture) ARCH=$(uname -m | sed 's/x86_64/amd64/' | sed 's/aarch64/arm64/') curl -LO "https://github.com/boshu2/gastown-operator/releases/download/v0.4.2/kubectl-gt-$(uname -s | tr '[:upper:]' '[:lower:]')-${ARCH}" chmod +x kubectl-gt-* && sudo mv kubectl-gt-* /usr/local/bin/kubectl-gt ``` ### 3. Create a Rig and Dispatch Work ```bash # Create a project rig kubectl gt rig create my-project \ --git-url https://github.com/org/repo.git \ --prefix mp \ -n gastown-system # Sync your Claude configuration to the cluster # This uploads your entire ~/.claude/ directory as a K8s Secret # so polecat pods can run Claude with your skills, hooks, and settings kubectl gt auth sync -n gastown-system # Dispatch a polecat to work on an issue kubectl gt sling issue-123 my-project --name furiosa -n gastown-system # Watch it work kubectl gt polecat logs my-project/furiosa -f -n gastown-system ``` **For AI Agents:** See [AGENT_INSTRUCTIONS.md](AGENT_INSTRUCTIONS.md) for setup instructions. --- ## kubectl-gt CLI (New in v0.4.1) **The recommended way to interact with Gas Town.** AI-native interface designed for both humans and agents. ### Core Commands | Command | Description | |---------|-------------| | `kubectl gt rig list` | List all rigs | | `kubectl gt rig status <name>` | Show rig details | | `kubectl gt rig create <name>` | Create a new rig | | `kubectl gt polecat list [rig]` | List polecats | | `kubectl gt polecat status <rig>/<name>` | Show polecat details | | `kubectl gt polecat logs <rig>/<name>` | Stream polecat logs | | `kubectl gt polecat nuke <rig>/<name>` | Terminate a polecat | | `kubectl gt sling <bead-id> <rig>` | Dispatch work to a polecat | | `kubectl gt convoy list` | List convoy batches | | `kubectl gt convoy create <desc> <beads...>` | Create convoy | | `kubectl gt auth sync` | Sync ~/.claude/ to cluster (skills, hooks, settings) | | `kubectl gt auth status` | Check credential status | ### AI-Native Features **JSON/YAML Output** - All commands support `-o json` and `-o yaml` for machine parsing: ```bash # Parse polecat list in scripts kubectl gt polecat list -o json | jq '.[] | .metadata.name' # Get rig status as YAML kubectl gt rig status my-rig -o yaml ``` **Themed Naming** - Memorable names for your polecats: ```bash # Named polecat kubectl gt sling at-1234 athena --name furiosa # Random themed name (mad-max, minerals, wasteland) kubectl gt sling at-1234 athena --theme mad-max # → Creates polecat named "capable" or "toast" etc. ``` **Wait for Ready** - Block until polecat pod is running: ```bash # Wait for pod to be scheduled and ready kubectl gt sling at-1234 athena --wait-ready --timeout 5m ``` **Native Log Streaming** - Stream logs directly without kubectl delegation: ```bash # Follow logs kubectl gt polecat logs athena/furiosa -f # Specific container kubectl gt polecat logs athena/furiosa -c claude -f ``` ### Installation See [Quick Start](#2-install-the-kubectl-plugin) for the one-liner, or build from source: ```bash make kubectl-gt-install ``` --- ## YAML Templates (Alternative) If you prefer declarative YAML over the CLI: ```yaml apiVersion: gastown.gastown.io/v1alpha1 kind: Polecat metadata: name: my-task spec: rig: my-project desiredState: Working kubernetes: gitRepository: "git@github.com:org/repo.git" gitSecretRef: name: git-ssh-key claudeCredsSecretRef: name: claude-creds task: description: "Implement feature X" ``` See [templates/](templates/) for all resource examples. ## Features | Feature | What It Means | |---------|---------------| | **Scale to 100+ agents** | Run 10, 50, or 100 polecats in parallel. No tmux limits. | | **One-command install** | `helm install` and you're running in 30 seconds | | **Instant agent startup** | Pre-built images with Claude Code. No npm install at runtime. | | **Enterprise-ready** | OpenShift native, FIPS-compliant edition, security-scanned | | **Agent-first docs** | Tell Claude to set it up. It reads the docs and configures itself. | | **Full lifecycle management** | Health monitoring, auto-cleanup, merge queue, convoy tracking | | **Multi-arch** | Runs on amd64 and arm64. Your infra, your choice. | | **Supply chain security** | SBOM, Trivy scans, provenance attestations on every image | **Why Kubernetes over local?** - **Horizontal scale**: Your laptop runs 20-30 agents. A cluster runs hundreds. - **Zero infrastructure**: No tmux, no screen, no SSH. Just pods. - **Built-in resilience**: Kubernetes restarts failed agents automatically. - **Resource isolation**: Each polecat gets dedicated CPU/memory. ## How It Works The operator is **CRD-driven**. You create a Polecat custom resource, and the operator handles the rest. ### Happy Path (Kubernetes Mode) ``` You Kubernetes Git │ │ │ ├─ kubectl apply polecat.yaml ─► │ │ (executionMode: kubernetes) │ │ │ │ │ │ Operator creates Pod │ │ │ │ │ ┌─────────▼─────────┐ │ │ │ Polecat Pod │ │ │ │ ┌─────────────┐ │ │ │ │ │ Claude Code │ │ │ │ │ │ - clones │──┼── git clone ───────► │ │ │ - works │ │ │ │ │ │ - commits │──┼── git push ────────► │ │ └─────────────┘ │ │ │ └───────────────────┘ │ │ │ │ ◄── kubectl get polecat ───────┤ │ (status: Done) │ │ ``` **Step by step:** 1. **Create secrets** for git SSH key and Claude credentials 2. **Apply a Polecat CR** with your task: ```yaml apiVersion: gastown.gastown.io/v1alpha1 kind: Polecat metadata: name: my-task spec: rig: my-project executionMode: kubernetes desiredState: Working kubernetes: gitRepository: "git@github.com:org/repo.git" gitSecretRef: name: git-ssh-key claudeCredsSecretRef: name: claude-creds task: description: "Implement feature X" ``` 3. **Operator creates a Pod** with Claude Code pre-installed 4. **Pod runs Claude**, which clones, implements, commits, and pushes 5. **Results appear in git** - the branch is pushed, PR created if configured 6. **Check status**: `kubectl get polecat my-task` ### What Goes Where | Data | Location | How to Access | |------|----------|---------------| | Work progress | Pod logs | `kubectl logs polecat-my-task` | | Final code | Git remote | Pushed to branch | | Polecat status | CRD status | `kubectl get polecat -o yaml` | ## Installation Options ### Option 1: Helm (Recommended) ```bash # Standard Kubernetes helm install gastown-operator oci://ghcr.io/boshu2/charts/gastown-operator \ --version 0.4.2 \ --namespace gastown-system \ --create-namespace ``` ### Option 2: Helm for OpenShift OpenShift requires stricter security settings: ```bash helm install gastown-operator oci://ghcr.io/boshu2/charts/gastown-operator \ --version 0.4.2 \ --namespace gastown-system \ --create-namespace \ --set securityContext.allowPrivilegeEscalation=false \ --set securityContext.runAsNonRoot=true \ --set securityContext.runAsUser=null \ --set securityContext.readOnlyRootFilesystem=true \ --set volumes.enabled=false ``` Or use the FIPS-compliant image for regulated environments: ```bash helm install gastown-operator oci://ghcr.io/boshu2/charts/gastown-operator \ --version 0.4.2 \ --namespace gastown-system \ --create-namespace \ --set image.tag=0.4.2-fips \ --set securityContext.allowPrivilegeEscalation=false \ --set securityContext.runAsNonRoot=true \ --set securityContext.runAsUser=null \ --set securityContext.readOnlyRootFilesystem=true \ --set volumes.enabled=false ``` ### Option 3: From Source ```bash make install # Install CRDs make deploy IMG=ghcr.io/boshu2/gastown-operator:0.4.2 ``` ## Custom Resources See [What Runs in Your Cluster](#what-runs-in-your-cluster) for details on each CR and what actually runs as pods. ## Templates Copy-paste YAML templates for all resources: | Template | Purpose | |----------|---------| | [polecat-minimal.yaml](templates/polecat-minimal.yaml) | Simple polecat example | | [polecat-kubernetes.yaml](templates/polecat-kubernetes.yaml) | Full polecat with all options | | [convoy.yaml](templates/convoy.yaml) | Batch tracking | | [witness.yaml](templates/witness.yaml) | Health monitoring | | [refinery.yaml](templates/refinery.yaml) | Merge processing | | [secret-git-ssh.yaml](templates/secret-git-ssh.yaml) | Git SSH credentials | | [secret-claude-creds.yaml](templates/secret-claude-creds.yaml) | Claude API credentials | Validate before applying: ```bash ./scripts/validate-template.sh templates/polecat-kubernetes.yaml ``` See [FRICTION_POINTS.md](FRICTION_POINTS.md) for common mistakes and fixes. ## Configuration ### Helm Values | Parameter | Default | Description | |-----------|---------|-------------| | `image.repository` | `ghcr.io/boshu2/gastown-operator` | Container image | | `image.tag` | `0.4.2` | Image tag | | `replicaCount` | `1` | Number of replicas | See [values.yaml](helm/gastown-operator/values.yaml) for full configuration. ## Architecture ``` ┌────────────────────────────────────────────────────────┐ │ Kubernetes Cluster │ │ │ │ ┌─────────────────────────────────────────────────┐ │ │ │ gastown-operator │ │ │ │ │ │ │ │ Rig Polecat Convoy Witness │ │ │ │ Controller Controller Controller Controller │ │ │ └──────────────────┬──────────────────────────────┘ │ │ │ │ │ ┌───────────┴───────────┐ │ │ ▼ ▼ │ │ ┌─────────────┐ ┌─────────────┐ │ │ │ Polecat │ ... │ Polecat │ │ │ │ (Pod) │ │ (Pod) │ │ │ │ ┌───────┐ │ │ ┌───────┐ │ │ │ │ │Claude │ │ │ │Claude │ │ ───► Git │ │ │ │ Code │ │ │ │ Code │ │ │ │ │ └───────┘ │ │ └───────┘ │ │ │ └─────────────┘ └─────────────┘ │ └────────────────────────────────────────────────────────┘ ``` The operator manages the full polecat lifecycle. Kubernetes handles scheduling, scaling, and restarts. ## Container Images All images are published to GHCR with SBOM, Trivy scans, and provenance attestations. | Image | Purpose | Tags | |-------|---------|------| | `ghcr.io/boshu2/gastown-operator` | Kubernetes operator | `0.4.2`, `latest`, `0.4.2-fips` | | `ghcr.io/boshu2/polecat-agent` | Pre-built polecat agent | `0.4.2`, `latest` | | `ghcr.io/boshu2/charts/gastown-operator` | Helm chart (OCI) | `0.4.2` | ### Polecat Agent Image The `polecat-agent` image comes with Claude Code pre-installed: ```bash docker pull ghcr.io/boshu2/polecat-agent:0.4.2 ``` **Benefits:** - Instant startup (no runtime npm install) - Pinned, documented component versions - Security-scanned (Trivy) with SBOM - No external network dependencies at runtime **Included components:** | Component | Version | |-----------|---------| | Claude Code | 2.0.22 (native binary) | | gt CLI | latest | | git, ssh, jq | system | See [images/polecat-agent/](images/polecat-agent/) for build details and [CUSTOMIZING.md](images/polecat-agent/CUSTOMIZING.md) to extend the image with your own tools. ## Requirements - Kubernetes 1.26+ or OpenShift 4.13+ - Helm 3.8+ - Git SSH credentials (for polecat git operations) - LLM API credentials (Anthropic, OpenAI, or Ollama) ## Editions | | **Community** | **Enterprise (FIPS)** | |---|---|---| | **Target** | Vanilla Kubernetes | OpenShift / Regulated | | **Base Image** | `distroless` | Red Hat UBI9 | | **Crypto** | Standard Go | FIPS-validated (BoringCrypto) | | **Image Tag** | `0.4.2` | `0.4.2-fips` | ## Related Projects - [Gas Town](https://github.com/steveyegge/gastown) - The multi-agent orchestration framework - [Claude Code](https://github.com/anthropics/claude-code) - AI coding agent from Anthropic - [Beads](https://github.com/steveyegge/beads) - Git-based issue tracking ## Advanced: Standalone Mode **Not using Gas Town?** You can run the operator standalone - just Kubernetes and Claude credentials. This is useful for CI/CD pipelines or teams that want K8s agents without the Gas Town workflow. ### What You Lose Standalone mode skips the Gas Town orchestration layer: | Feature | With Gas Town | Standalone | |---------|---------------|------------| | Beads issue tracking | Yes | No | | Inter-agent mail | Yes | No | | Convoy batching | Yes | Manual only | | Skills/hooks from ~/.claude/ | Synced automatically | Mount manually | | `gt sling` dispatch | Yes | kubectl apply | ### Standalone YAML Example ```yaml apiVersion: gastown.gastown.io/v1alpha1 kind: Polecat metadata: name: standalone-task namespace: gastown-system spec: rig: standalone executionMode: kubernetes desiredState: Working kubernetes: gitRepository: "git@github.com:your-org/your-repo.git" gitSecretRef: name: git-ssh-key claudeCredsSecretRef: name: claude-creds task: description: | Implement feature X. Requirements: - Add new endpoint /api/v1/feature - Include tests - Update API documentation ``` Create the secrets first: ```bash # Claude API key kubectl create secret generic claude-creds \ --from-literal=ANTHROPIC_API_KEY=sk-ant-xxx \ -n gastown-system # Git SSH key kubectl create secret generic git-ssh-key \ --from-file=ssh-privatekey=$HOME/.ssh/id_ed25519 \ -n gastown-system ``` Then apply: ```bash kubectl apply -f polecat.yaml kubectl logs -f -l gastown.io/polecat=standalone-task -n gastown-system ``` For the full Gas Town experience (beads, mail, skills), install Gas Town first: [github.com/steveyegge/gastown](https://github.com/steveyegge/gastown) --- ## Contributing PRs welcome.
