# Port Forward
View and manage port mappings for Kurtosis services.
## View port info
```bash
kurtosis port print <enclave-name> <service-name> <port-id>
```
This prints the local URL for a specific port.
## Find all ports
The easiest way to see all port mappings is enclave inspect:
```bash
kurtosis enclave inspect <enclave-name>
```
Output shows mappings like:
```
rpc: 8545/tcp -> 127.0.0.1:61817
ws: 8546/tcp -> 127.0.0.1:61813
```
The right side (`127.0.0.1:61817`) is how you access the service locally.
## Port IDs
Port IDs are defined in the Starlark ServiceConfig:
```python
plan.add_service(
name="my-service",
config=ServiceConfig(
image="ethereum/client-go:latest",
ports={
"rpc": PortSpec(number=8545), # port ID: "rpc"
"ws": PortSpec(number=8546), # port ID: "ws"
"metrics": PortSpec(number=9001), # port ID: "metrics"
},
),
)
```
## No-connect mode
If you ran with `--no-connect`, ports won't be forwarded locally:
```bash
# Ports not forwarded
kurtosis run --no-connect ./my-package
# Ports forwarded (default)
kurtosis run ./my-package
```
## Kubernetes
On Kubernetes, port forwarding goes through the gateway. If ports stop working, restart the gateway:
```bash
pkill -f "kurtosis gateway"
kurtosis gateway &
```
## Troubleshooting
When a port is unreachable, follow this diagnostic workflow:
```bash
# 1. Verify the enclave is running and check port mappings
kurtosis enclave inspect <enclave-name>
# 2. Confirm the specific service is running (not STOPPED)
kurtosis service inspect <enclave-name> <service-name>
# 3. If service is running but port fails, check service logs for errors
kurtosis service logs <enclave-name> <service-name>
# 4. On Kubernetes, verify the gateway is running
kurtosis gateway
```
| Symptom | Cause | Fix |
|---------|-------|-----|
| Port not accessible | Service not running or port not exposed | Check step 1-2 above |
| Connection refused | Service crashed or wrong interface | Check service logs (step 3) |
| No port mapping shown | Ran with `--no-connect` | Re-run without `--no-connect` |
| K8s ports unreachable | Gateway not running | Restart gateway (step 4) |Related Skills
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.
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.
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.
run-package
Run Starlark scripts and packages with kurtosis run. Covers all flags including dry-run, args-file, parallel execution, image download modes, verbosity levels, and production mode. Use when executing Kurtosis packages locally or from GitHub.
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.
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.
