**Kubeshark** is an API Traffic Analyzer for [**Kubernetes**](https://kubernetes.io/) providing real-time, protocol-level visibility into Kubernetes’ internal network, capturing and monitoring all traffic and payloads going in, out and across containers, pods, nodes and clusters.
|
||||
---
|
||||
|
||||

|
||||
* **Cluster-wide, real-time visibility into every packet, API call, and service interaction.**
|
||||
* Replay any moment in time.
|
||||
* Resolve incidents at the speed of LLMs. 100% on-premises.
|
||||
|
||||
Think [TCPDump](https://en.wikipedia.org/wiki/Tcpdump) and [Wireshark](https://www.wireshark.org/) re-invented for Kubernetes
|
||||

|
||||
|
||||
## Getting Started
|
||||
---
|
||||
|
||||
Download **Kubeshark**'s binary distribution [latest release](https://github.com/kubeshark/kubeshark/releases/latest) and run following one of these examples:
|
||||
## Get Started
|
||||
|
||||
```shell
|
||||
kubeshark tap
|
||||
```bash
|
||||
helm repo add kubeshark https://helm.kubeshark.com
|
||||
helm install kubeshark kubeshark/kubeshark
|
||||
```
|
||||
|
||||
```shell
|
||||
kubeshark tap -n sock-shop "(catalo*|front-end*)"
|
||||
```
|
||||
Dashboard opens automatically. You're capturing traffic.
|
||||
|
||||
Running any of the :point_up: above commands will open the [Web UI](https://docs.kubeshark.co/en/ui) in your browser which streams the traffic in your Kubernetes cluster in real-time.
|
||||
**With AI** — connect your assistant and debug with natural language:
|
||||
|
||||
### Homebrew
|
||||
|
||||
[Homebrew](https://brew.sh/) :beer: users install Kubeshark CLI with:
|
||||
|
||||
```shell
|
||||
```bash
|
||||
brew install kubeshark
|
||||
claude mcp add kubeshark -- kubeshark mcp
|
||||
```
|
||||
|
||||
### Helm
|
||||
> *"Why did checkout fail at 2:15 PM?"*
|
||||
> *"Which services have error rates above 1%?"*
|
||||
|
||||
Add the helm repository and install the chart:
|
||||
[MCP setup guide →](https://docs.kubeshark.com/en/mcp)
|
||||
|
||||
```shell
|
||||
helm repo add kubeshark https://helm.kubeshark.co
|
||||
helm install kubeshark kubeshark/kubeshark
|
||||
```
|
||||

|
||||
|
||||
## Building From Source
|
||||
## Why Kubeshark
|
||||
|
||||
Clone this repository and run `make` command to build it. After the build is complete, the executable can be found at `./bin/kubeshark__`.
|
||||
- **Instant root cause** — trace requests across services, see exact errors
|
||||
- **Zero instrumentation** — no code changes, no SDKs, just deploy
|
||||
- **Full payload capture** — request/response bodies, headers, timing
|
||||
- **TLS decryption** — see encrypted traffic without managing keys
|
||||
- **AI-ready** — query traffic with natural language via MCP
|
||||
|
||||

### Traffic Analysis and API Dissection
|
||||
|
||||
Capture and inspect every API call across your cluster—HTTP, gRPC, Redis, Kafka, DNS, and more. Request/response matching with full payloads, parsed according to protocol specifications. Headers, timing, and complete context. Zero instrumentation required.

### L4/L7 Workload Map
|
||||
|
||||
Visualize how your services communicate. See dependencies, traffic flow, and identify anomalies at a glance.

|
||||
### AI-Powered Root Cause Analysis
|
||||
|
||||
Resolve production issues in minutes instead of hours. Connect your AI assistant and investigate incidents using natural language. Build network-aware AI agents for forensics, monitoring, compliance, and security.
|
||||
|
||||
> *"Why did checkout fail at 2:15 PM?"*
|
||||
> *"Which services have error rates above 1%?"*
|
||||
> *"Trace request abc123 through all services"*
|
||||
|
||||
Works with Claude Code, Cursor, and any MCP-compatible AI.

Long: `Run an MCP server over stdio that exposes Kubeshark's L7 API visibility
|
||||
to AI assistants like Claude Desktop.
|
||||
|
||||
TOOLS PROVIDED:
|
||||
|
||||
Cluster Management (work without Kubeshark running):
|
||||
- check_kubeshark_status: Check if Kubeshark is running in the cluster
|
||||
- start_kubeshark: Start Kubeshark to capture traffic
|
||||
- stop_kubeshark: Stop Kubeshark and clean up resources
|
||||
|
||||
Traffic Analysis (require Kubeshark running):
|
||||
- list_workloads: Discover pods, services, namespaces, and nodes with L7 traffic
|
||||
- list_api_calls: Query L7 API transactions (HTTP, gRPC, etc.)
|
||||
- get_api_call: Get detailed information about a specific API call
|
||||
- get_api_stats: Get aggregated API statistics
|
||||
|
||||
CONFIGURATION:
|
||||
|
||||
To use with Claude Desktop, add to your claude_desktop_config.json
|
||||
(typically at ~/Library/Application Support/Claude/claude_desktop_config.json):
|
||||
|
||||
{
|
||||
"mcpServers": {
|
||||
"kubeshark": {
|
||||
"command": "/path/to/kubeshark",
|
||||
"args": ["mcp", "--kubeconfig", "/Users/YOUR_USERNAME/.kube/config"]
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
DIRECT URL MODE:
|
||||
|
||||
If Kubeshark is already running and accessible via URL (e.g., exposed via ingress),
|
||||
you can connect directly without needing kubectl/kubeconfig:
|
||||
|
||||
{
|
||||
"mcpServers": {
|
||||
"kubeshark": {
|
||||
"command": "/path/to/kubeshark",
|
||||
"args": ["mcp", "--url", "https://kubeshark.example.com"]
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
In URL mode, destructive tools (start/stop) are disabled since Kubeshark is
|
||||
managed externally. The check_kubeshark_status tool remains available to confirm connectivity.
|
||||
|
||||
DESTRUCTIVE OPERATIONS:
|
||||
|
||||
By default, destructive operations (start_kubeshark, stop_kubeshark) are disabled
|
||||
to prevent accidental cluster modifications. To enable them, use --allow-destructive:
|
||||
|
||||
{
|
||||
"mcpServers": {
|
||||
"kubeshark": {
|
||||
"command": "/path/to/kubeshark",
|
||||
"args": ["mcp", "--allow-destructive", "--kubeconfig", "/path/to/.kube/config"]
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
CUSTOM SETTINGS:
|
||||
|
||||
To use custom settings when starting Kubeshark, use the --set flag:
|
||||
|
||||
{
|
||||
"mcpServers": {
|
||||
"kubeshark": {
|
||||
"command": "/path/to/kubeshark",

||||
"args": ["mcp", "--set", "tap.docker.tag=v52.3"],
|
||||
...
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
Multiple --set flags can be used for different settings.`,

||||

|
||||
|
||||
## Overview
|
||||
|
||||
PF_RING™ is an advanced Linux kernel module and user-space framework designed for high-speed packet processing. It offers a uniform API for packet processing applications, enabling efficient handling of large volumes of network data.
|
||||
|
||||
For comprehensive information on PF_RING™, please visit the [User's Guide]((https://www.ntop.org/guides/pf_ring) and access detailed [API Documentation](http://www.ntop.org/guides/pf_ring_api/files.html).
|
||||
|
||||
## Loading PF_RING module on Kubernetes nodes
|
||||
|
||||
PF_RING kernel module loading is performed via of the `worker` component pod.
|
||||
The target container `tap.kernelModule.image` must contain `pf_ring.ko` file under path `/opt/lib/modules/<kernel version>/pf_ring.ko`.
|
||||
Kubeshark provides ready to use containers with kernel modules for the most popular kernel versions running in different managed clouds.
|
||||
|
||||
Prior to deploying `kubeshark` with PF_RING enabled, it is essential to verify if a PF_RING kernel module is already built for your kernel version.
|
||||
Kubeshark provides additional CLI tool for this purpose - [pf-ring-compiler](https://github.com/kubeshark/pf-ring-compiler).
|
||||
|
||||
Compatibility verification can be done by running:
|
||||
|
||||
```bash
|
||||
pfring-compiler compatibility
|
||||
```
|
||||
|
||||
This command checks for the availability of kernel modules for the kernel versions running across all nodes in the Kubernetes cluster.
|
||||
|
||||
Example output for a compatible cluster:
|
||||
|
||||
```bash
|
||||
Node Kernel Version Supported
|
||||
ip-192-168-77-230.us-west-2.compute.internal 5.10.199-190.747.amzn2.x86_64 true
|
||||
ip-192-168-34-216.us-west-2.compute.internal 5.10.199-190.747.amzn2.x86_64 true
|
||||
|
||||
Cluster is compatible
|
||||
```
|
||||
|
||||
Another option to verify availability of kernel modules is just inspecting available kernel module versions via:
|
||||
|
||||
```bash
|
||||
curl https://api.kubeshark.co/kernel-modules/meta/versions.jso
|
||||
```
|
||||
|
||||
Based on Kubernetes cluster compatibility and external connection capabilities, user has two options:
|
||||
|
||||
1. Use Kubeshark provided container `kubeshark/pf-ring-module`
|
||||
2. Build custom container with required kernel module version.
|
||||
|
||||
### Pre-built kernel module exists and external egress allowed
|
||||
|
||||
In this case no additional configuration required.
|
||||
Kubeshark will load PF_RING kernel module from the default `kubeshark/pf-ring-module:all` container.
|
||||
|
||||
### Pre-built kernel module doesn't exist or external egress isn't allowed
|
||||
|
||||
In this case building custom Docker image is required.
|
||||
|
||||
1. Compile PF_RING kernel module for target version
|
||||
|
||||
Skip if you have `pf_ring.ko` for the target kernel version.
|
||||
Otherwise, follow [Appendix A](#appendix-a-pf_ring-kernel-module-compilation) for details.
|
||||
|
||||
2. Build container
|
||||
|
||||
The same build process Kubeshark has can be reused (follow [pfring-compilier](https://github.com/kubeshark/pf-ring-compiler/tree/main/modules) for details).
|
||||
|
||||
3. Configure Helm values
|
||||
|
||||
```yaml
|
||||
tap:
|
||||
kernelModule:
|
||||
image: <container from stage 2>
|
||||
```
|
||||
|
||||
|
||||
## Appendix A: PF_RING kernel module compilation
|
||||
|
||||
PF_RING kernel module compilation can be completed automatically or manually.
|
||||
|
||||
### Automated complilation
|
||||
|
||||
In case your Kubernetes workers run supported Linux distribution, `kubeshark` CLI can be used to build PF_RING module:
|
||||
|
||||
```bash
|
||||
pfring-compiler compile --target <distro>
|
||||
```
|
||||
|
||||
This command requires:
|
||||
|
||||
- kubectl to be installed and configured with a proper context
|
||||
- egress connection to Internet available
|
||||
|
||||
This command:
|
||||
|
||||
1. Runs Kubernetes job with build container
|
||||
2. Waits for job to be completed
|
||||
3. Downloads `pf-ring-<kernel version>.ko` file into the current folder.
|
||||
4. Cleans up created job.
|
||||
|
||||
Currently supported distros:
|
||||
|
||||
- Ubuntu
|
||||
- RHEL 9
|
||||
- Amazon Linux 2
|
||||
|
||||
### Manual compilation
|
||||
|
||||
The process description is based on Ubuntu 22.04 distribution.
|
||||
|
||||
1. Get terminal access to the node with target kernel version
|
||||
This can be done either via SSH directly to node or with debug container running on the target node:
|
||||
|
||||
```bash
|
||||
kubectl debug node/<target node> -it --attach=true --image=ubuntu:22.04
|
||||
```
|
||||
|
||||
2. Install build tools and kernel headers
|
||||
|
||||
```bash
|
||||
apt update
|
||||
apt install -y gcc build-essential make git wget tar gzip
|
||||
apt install -y linux-headers-$(uname -r)
|
||||
```
|
||||
|
||||
3. Download PF_RING source code
|
||||
|
||||
```bash
|
||||
wget https://github.com/ntop/PF_RING/archive/refs/tags/8.4.0.tar.gz
|
||||
tar -xf 8.4.0.tar.gz
|
||||
cd PF_RING-8.4.0/kernel
|
||||
```
|
||||
|
||||
4. Compile the kernel module
|
||||
|
||||
```bash
|
||||
make KERNEL_SRC=/usr/src/linux-headers-$(uname -r)
|
||||
```
|
||||
|
||||
5. Copy `pf_ring.ko` to the local file system.
|
||||
|
||||
Use `scp` or `kubectl cp` depending on type of access(SSH or debug pod).

## Override Tag, Tags, Images
|
||||
|
||||
In addition to using a private registry, you can further override the images' tag, specific image tags and specific image names.
|
||||
|
||||
Example for overriding image names:
|
||||
|
||||
```yaml
|
||||
docker:

# Installing with Dex OIDC authentication
|
||||
|
||||
[**Click here to see full docs**](https://docs.kubeshark.com/en/saml#installing-with-oidc-enabled-dex-idp).
|
||||
|
||||
Choose this option, if **you already have a running instance** of Dex in your cluster &
|
||||
you want to set up Dex OIDC authentication for Kubeshark users.
|
||||
|
||||
Kubeshark supports authentication using [Dex - A Federated OpenID Connect Provider](https://dexidp.io/).
|
||||
Dex is an abstraction layer designed for integrating a wide variety of Identity Providers.
|
||||
|
||||
**Requirement:**
|
||||
Your Dex IdP must have a publicly accessible URL.
|
||||
|
||||
### Pre-requisites:
|
||||
|
||||
**1. If you configured Ingress for Kubeshark:**
|
||||
|
||||
(see section: "Installing with Ingress (EKS) enabled")
|
||||
|
||||
OAuth2 callback URL is: <br/>
|
||||
`https://<kubeshark-ingress-hostname>/api/oauth2/callback`
|
||||
|
||||
**2. If you did not configure Ingress for Kubeshark:**
|
||||
|
||||
OAuth2 callback URL is: <br/>
|
||||
`http://0.0.0.0:8899/api/oauth2/callback`
|
||||
|
||||
Use chosen OAuth2 callback URL to replace `<your-kubeshark-host>` in Step 3.
|
||||
|
||||
**3. Add this static client to your Dex IdP configuration (`config.yaml`):**
|
||||
```yaml
|
||||
staticClients:
|
||||
- id: kubeshark
|
||||
secret: create your own client password
|
||||
name: Kubeshark
|
||||
redirectURIs:
|
||||
- https://<your-kubeshark-host>/api/oauth2/callback
|
||||
```
|
||||
|
||||
**Final step:**
|
||||
|
||||
Add these helm values to set up OIDC authentication powered by your Dex IdP:
|
||||
|
||||
```yaml
|
||||
# values.yaml
|
||||
|
||||
tap:
|
||||
auth:
|
||||
enabled: true
|
||||
type: dex
|
||||
dexOidc:
|
||||
issuer: <put Dex IdP issuer URL here>
|
||||
clientId: kubeshark
|
||||
clientSecret: create your own client password
|
||||
refreshTokenLifetime: "3960h" # 165 days
|
||||
oauth2StateParamExpiry: "10m"
|
||||
bypassSslCaCheck: false
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
**Note:**<br/>
|
||||
Set `tap.auth.dexOidc.bypassSslCaCheck: true`
|
||||
to allow Kubeshark communication with Dex IdP having an unknown SSL Certificate Authority.
|
||||
|
||||
This setting allows you to prevent such SSL CA-related errors:<br/>
|
||||
`tls: failed to verify certificate: x509: certificate signed by unknown authority`
|
||||
|
||||
---
|
||||
|
||||
Once you run `helm install kubeshark kubeshark/kubeshark -f ./values.yaml`, Kubeshark will be installed with (Dex) OIDC authentication enabled.
|
||||
|
||||
---
|
||||
|
||||
# Installing your own Dex IdP along with Kubeshark
|
||||
|
||||
Choose this option, if **you need to deploy an instance of Dex IdP** along with Kubeshark &
|
||||
set up Dex OIDC authentication for Kubeshark users.
|
||||
|
||||
Depending on Ingress enabled/disabled, your Dex configuration might differ.
|
||||
|
||||
**Requirement:**
|
||||
Please, configure Ingress using `tap.ingress` for your Kubeshark installation. For example:
|
||||
|
||||
```yaml
|
||||
tap:
|
||||
ingress:
|
||||
enabled: true
|
||||
className: "alb"
|
||||
host: ks.example.com
|
||||
tls: []
|
||||
annotations:
|
||||
alb.ingress.kubernetes.io/certificate-arn: arn:aws:acm:us-east-1:7..8:certificate/b...65c
|
||||
alb.ingress.kubernetes.io/target-type: ip
|
||||
alb.ingress.kubernetes.io/scheme: internet-facing
|
||||
```
|
||||
|
||||
The following Dex settings will have these values:
|
||||
|
||||
| Setting | Value |
|
||||
|-------------------------------------------------------|----------------------------------------------|
|
||||
| `tap.auth.dexOidc.issuer` | `https://ks.example.com/dex` |
|
||||
| `tap.auth.dexConfig.issuer` | `https://ks.example.com/dex` |
|
||||
| `tap.auth.dexConfig.staticClients -> redirectURIs` | `https://ks.example.com/api/oauth2/callback` |
|
||||
| `tap.auth.dexConfig.connectors -> config.redirectURI` | `https://ks.example.com/dex/callback` |
|
||||
|
||||
---
|
||||
|
||||
### Before proceeding with Dex IdP installation:
|
||||
|
||||
Please, make sure to prepare the following things first.
|
||||
|
||||
1. Choose **[Connectors](https://dexidp.io/docs/connectors/)** to enable in Dex IdP.
|
||||
- i.e. how many kind of "Log in with ..." options you'd like to offer your users
|
||||
- You will need to specify connectors in `tap.auth.dexConfig.connectors`
|
||||
2. Choose type of **[Storage](https://dexidp.io/docs/configuration/storage/)** to use in Dex IdP.
|
||||
- You will need to specify storage settings in `tap.auth.dexConfig.storage`
|
||||
- default: `memory`
|
||||
3. Decide on the OAuth2 `?state=` param expiration time:
|
||||
- field: `tap.auth.dexOidc.oauth2StateParamExpiry`
|
||||
- default: `10m` (10 minutes)
|
||||
- valid time units are `s`, `m`, `h`
|
||||
4. Decide on the refresh token expiration:
|
||||
- field 1: `tap.auth.dexOidc.expiry.refreshTokenLifetime`
|
||||
- field 2: `tap.auth.dexConfig.expiry.refreshTokens.absoluteLifetime`
|
||||
- default: `3960h` (165 days)
|
||||
- valid time units are `s`, `m`, `h`
|
||||
5. Create a unique & secure password to set in these fields:
|
||||
- field 1: `tap.auth.dexOidc.clientSecret`
|
||||
- field 2: `tap.auth.dexConfig.staticClients -> secret`
|
||||
- password must be the same for these 2 fields
|
||||
6. Discover more possibilities of **[Dex Configuration](https://dexidp.io/docs/configuration/)**
|
||||
- if you decide to include more configuration options, make sure to add them into `tap.auth.dexConfig`
|
||||
---
|
||||
|
||||
### Once you are ready with all the points described above:
|
||||
|
||||
Use these helm `values.yaml` fields to:
|
||||
- Deploy your own instance of Dex IdP along with Kubeshark
|
||||
- Enable OIDC authentication for Kubeshark users
|
||||
|
||||
Make sure to:
|
||||
- Replace `<your-ingress-hostname>` with a correct Kubeshark Ingress host (`tap.auth.ingress.host`).
|
||||
- refer to section **Installing with Ingress (EKS) enabled** to find out how you can configure Ingress host.
|
||||
|
||||
Helm `values.yaml`:
|

# Integration Tests
|
||||
|
||||
This directory contains integration tests that run against a real Kubernetes cluster.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
1. **Kubernetes cluster** - A running cluster accessible via `kubectl`
|
||||
2. **kubectl** - Configured with appropriate context
|
||||
3. **Go 1.21+** - For running tests
|
||||
|
||||
## Running Tests
|
||||
|
||||
```bash
|
||||
# Run all integration tests
|
||||
make test-integration
|
||||
|
||||
# Run specific command tests
|
||||
make test-integration-mcp
|
||||
|
||||
# Run with verbose output
|
||||
make test-integration-verbose
|
||||
|
||||
# Run with custom timeout (default: 5m)
|
||||
INTEGRATION_TIMEOUT=10m make test-integration
|
||||
```
|
||||
|
||||
## Environment Variables
|
||||
|
||||
| Variable | Default | Description |
|
||||
|----------|---------|-------------|
|
||||
| `KUBESHARK_BINARY` | Auto-built | Path to pre-built kubeshark binary |
|
||||
| `INTEGRATION_TIMEOUT` | `5m` | Test timeout duration |
|
||||
| `KUBECONFIG` | `~/.kube/config` | Kubernetes config file |
|
||||
| `INTEGRATION_SKIP_CLEANUP` | `false` | Skip cleanup after tests (for debugging) |
|
||||
|
||||
## Test Structure
|
||||
|
||||
```
|
||||
integration/
|
||||
├── README.md # This file
|
||||
├── common_test.go # Shared test helpers
|
||||
├── mcp_test.go # MCP command integration tests
|
||||
├── tap_test.go # Tap command tests (future)
|
||||
└── ... # Additional command tests
|
||||
```
|
||||
|
||||
## Writing New Tests
|
||||
|
||||
1. Create `<command>_test.go` with build tag `//go:build integration`
|
||||
2. Use helpers from `common_test.go`: `requireKubernetesCluster(t)`, `getKubesharkBinary(t)`, `cleanupKubeshark(t, binary)`
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
```bash
|
||||
# JSON output for CI parsing
|
||||
go test -tags=integration -json ./integration/...
|
||||

# Kubeshark MCP Server
|
||||
|
||||
[Kubeshark](https://kubeshark.com) MCP (Model Context Protocol) server enables AI assistants like Claude Desktop, Cursor, and other MCP-compatible clients to query real-time Kubernetes network traffic.
|
||||
|
||||
## Features
|
||||
|
||||
- **L7 API Traffic Analysis**: Query HTTP, gRPC, Redis, Kafka, DNS transactions
|
||||
- **L4 Network Flows**: View TCP/UDP flows with traffic statistics
|
||||
- **Cluster Management**: Start/stop Kubeshark deployments (with safety controls)
|
||||
- **PCAP Snapshots**: Create and export network captures
|
||||
- **Built-in Prompts**: Pre-configured prompts for common analysis tasks
|
||||
|
||||
## Installation
|
||||
|
||||
### 1. Install Kubeshark CLI

## MCP Registry
|
||||
|
||||
Kubeshark is published to the [MCP Registry](https://registry.modelcontextprotocol.io/) automatically on each release.
|
||||
|
||||
The `server.json` in this directory is a reference file. The actual registry metadata (version, SHA256 hashes) is auto-generated during the release workflow. See [`.github/workflows/release.yml`](../.github/workflows/release.yml) for details.
