Kagent Go Workspace

This directory is a Go workspace (go.work) containing three modules that make up the Go components of Kagent.

Modules

Module	Path	Description
api	go/api/	Shared types: CRD definitions, ADK model types, database models, HTTP client SDK
core	go/core/	Infrastructure: Kubernetes controllers, HTTP server, CLI, database implementation
adk	go/adk/	Go Agent Development Kit for building and running agents

Dependency graph

go/api  (shared types — no internal kagent deps)

Building

All commands are run from the go/ directory via the unified Makefile.

# Generate CRD manifests and DeepCopy methods (after changing api/ types)
make generate
make manifests

# Build CLI binaries for all platforms
make build

# Build CLI for local development
make core/bin/kagent-local

# Run the controller locally
make run

Testing

# Run all unit tests across the workspace
make test

# Run end-to-end tests (requires Kind cluster)
make e2e

Code Quality

# Lint all modules
make lint

# Auto-fix lint issues
make lint-fix

# Format all modules
make fmt

# Vet all modules
make vet

Docker

The workspace uses a single Dockerfile parameterized with BUILD_PACKAGE:

# Build controller image (default)
docker build --build-arg BUILD_PACKAGE=core/cmd/controller/main.go -t controller .

# Build Go ADK image
docker build --build-arg BUILD_PACKAGE=adk/cmd/main.go -t golang-adk .

In practice, use the root Makefile targets (make build-controller, make build-golang-adk).

Quick Testing with Oneshot

The adk/examples/oneshot tool lets you test agent configs locally:

# Extract config from a running agent
kubectl get secret -n kagent k8s-agent -ojson | jq -r '.data."config.json"' | base64 -d > /tmp/config.json

# Run a single prompt
cd go/adk && go run ./examples/oneshot -config /tmp/config.json -task "Hello"
