# Run Package
Execute Starlark scripts and packages with `kurtosis run`.
## Basic usage
```bash
# Run a local package
kurtosis run ./my-package
# Run a local .star script
kurtosis run ./script.star
# Run a remote package from GitHub
kurtosis run github.com/ethpandaops/ethereum-package
# Run with inline args
kurtosis run github.com/ethpandaops/ethereum-package '{"participants": [{"el_type": "geth", "cl_type": "lighthouse"}]}'
# Run with args from a file (JSON or YAML)
kurtosis run github.com/ethpandaops/ethereum-package --args-file config.yaml
```
## Named enclaves
```bash
# Run in a specific enclave (created if it doesn't exist)
kurtosis run --enclave my-testnet github.com/ethpandaops/ethereum-package
# Re-run in an existing enclave (adds to it)
kurtosis run --enclave my-testnet ./additional-services.star
```
## Dry run
Preview what will execute without making changes:
```bash
kurtosis run --dry-run github.com/ethpandaops/ethereum-package --args-file config.yaml
```
## Verbosity levels
```bash
# Default — concise description of what happens
kurtosis run ./my-package
# Brief — concise but explicit
kurtosis run -v brief ./my-package
# Detailed — all arguments for each instruction
kurtosis run -v detailed ./my-package
# Executable — generates copy-pasteable Starlark
kurtosis run -v executable ./my-package
# Output only — just the return value
kurtosis run -v output_only ./my-package
```
## Image handling
```bash
# Default: only pull if image doesn't exist locally
kurtosis run ./my-package
# Always pull latest image tags
kurtosis run --image-download always ./my-package
```
## Parallel execution
```bash
# Run instructions in parallel (as soon as dependencies resolve)
kurtosis run --parallel ./my-package
# Set parallelism level
kurtosis run --parallel --parallelism 8 ./my-package
```
## Advanced options
```bash
# Production mode — services auto-restart on failure
kurtosis run -p ./my-package
# Custom entry point file
kurtosis run --main-file deploy.star ./my-package
# Custom main function
kurtosis run --main-function-name setup ./my-package
# Don't forward ports locally
kurtosis run --no-connect ./my-package
# Show dependency graph
kurtosis run --output-graph ./my-package
# List image and package dependencies
kurtosis run --dependencies ./my-package
# Pull all dependencies locally
kurtosis run --pull --dependencies ./my-package
# Skip enclave inspect output
kurtosis run --show-enclave-inspect=false ./my-package
```
## Safe deployment workflow
Preview, execute, then verify:
```bash
# 1. Dry run — validate the plan without making changes
kurtosis run --dry-run --enclave my-testnet github.com/ethpandaops/ethereum-package --args-file config.yaml
# 2. Execute — run the package for real
kurtosis run --enclave my-testnet github.com/ethpandaops/ethereum-package --args-file config.yaml
# 3. Verify — confirm services are running correctly
kurtosis enclave inspect my-testnet
```
## Debug mode
```bash
# Run with debug engine images
kurtosis --debug-mode run ./my-package
# Increase CLI log verbosity
kurtosis --cli-log-level debug run ./my-package
```Related Skills
starlark-dev
Develop and debug Kurtosis Starlark packages. Create packages from scratch, understand the plan-based execution model, use print() debugging, handle future references, and test packages locally. Use when writing or troubleshooting .star files.
service-manage
Manage services in Kurtosis enclaves. Add, inspect, stop, start, remove, update services. View logs, shell into containers, and execute commands. Use when you need to interact with running services.
portal
Manage Kurtosis Portal for remote context access. Start, stop, and check status of the Portal daemon that enables communication with remote Kurtosis servers. Use when working with remote Kurtosis contexts.
port-forward
View and manage port mappings for Kurtosis services. Check which local ports map to service ports and troubleshoot connectivity. Use when services aren't reachable or you need to find the right port.
lint
Lint and format Kurtosis Starlark files. Check syntax, validate docstrings, and auto-format .star files. Use when writing or reviewing Starlark packages to ensure code quality.
k8s-dev-deploy
Build, push, and deploy Kurtosis dev images to a Kubernetes cluster without creating a release. Rebuilds engine, core, and files-artifacts-expander as multi-arch Docker images with a unique tag, pushes to the logged-in user's Docker Hub, and restarts the engine. Use when testing local code changes on a k8s cluster.
k8s-debug-pods
Debug Kurtosis pods on Kubernetes. Diagnose why pods are Pending, CrashLoopBackOff, ImagePullBackOff, or Evicted. Check node taints, tolerations, resource pressure, and pod events. Use when kurtosis engine start fails or pods aren't coming online.
k8s-clean-cluster
Force-clean all Kurtosis resources from a Kubernetes cluster when kurtosis clean hangs or fails. Removes all kurtosis namespaces, pods, daemonsets, cluster roles, and cluster role bindings. Use when kurtosis clean -a hangs or leaves behind orphaned resources.
import-compose
Import Docker Compose files into Kurtosis. Convert docker-compose.yml to Starlark packages or run them directly. Use when migrating existing Docker Compose workflows to Kurtosis.
grafloki
Start Grafana and Loki for centralized log collection from Kurtosis enclaves. View aggregated service logs in a Grafana dashboard. Use when you need a UI for browsing logs across multiple services or want persistent log storage.
gateway
Start and manage the Kurtosis gateway for Kubernetes. The gateway forwards local ports to the Kurtosis engine and services running in a k8s cluster. Required when using Kurtosis with Kubernetes. Use when kurtosis engine status shows nothing on k8s or services aren't reachable.
files-inspect
Inspect, download, upload, and debug Kurtosis file artifacts. View artifacts in an enclave, download them locally for inspection, upload local files, and troubleshoot file mounting issues. Use when services can't find expected files or configs are wrong.
