# k8s-insider
A zero-config way to access you kubernetes cluster network
## Overview
Originally a workaround that got out of hand, k8s-insider is a one-stop-shop for accessing your development kubernetes cluster networked resources.
The app works by deploying an operator to the cluster and applying CRDs with network and tunnel definitions, which are then reconciled by the operator pods. After networks and tunnels are applied to the cluster and reconciled, the CLI app reads their state and generates and/or applies WireGuard configurations on the user's machine.
`Network` and `Tunnel` CRDs are namespaced and can be RBACed easily. The traffic is routed through separate _router_ pods and can be shaped with network policies.
## Features
- Multiple networks per cluster
- Dynamic IP assignment
- Automatic detection of service and pod CIDRs for:
- Flannel (installed with Helm/CLI)
- Cilium (installed with Helm/CLI)
- DNS resolution for pods and services
## Planned features
- NAT-free routing
- IPv6 support
## Requirements
- GNU/Linux:
- `kubectl` with configured contexts
- `wireguard-tools` for creating local tunnels
- `systemd-resolved` for DNS patch functionality
- Windows:
- `kubectl` with configured contexts
- `WireGuard for Windows` for creating local tunnels
## Installation
### `cargo` (GNU/Linux and Windows)
```bash
cargo install --locked k8s-insider
```
## Quickstart
```bash
k8s-insider install
k8s-insider create network
k8s-insider connect
```
## Current limitations
Some autodetection functionality might not work properly on single-binary kubernetes distributions (k3s, k0s, etc.). Please feel free to create an issue or submit a PR for these.
