**kimspect** is a kubernetes container image inspection tool that provides comprehensive visibility into container images running inside your cluster. kimspect can get image information by pod, namespace, and node. Built for performance and reliability, kimspect enables container image insights with a simple, intuitive command-line interface.

_For more demos, checkout the .vhs folder_

## Features

- [x] List images in a cluster based on different filters:
  - by namespace
  - by node
  - by pod name
  - by container image registry
- [x] Advanced logging capabilities:
  - Multiple verbosity levels (-v, -vv, -vvv, -vvvv)
  - Support for both plain and JSON log formats

## Installation

kimspect can be installed using several package managers. Choose the one that suits your environment:

### Using Cargo (Rust's Package Manager)

If you have Rust and Cargo installed, you can build and install kimspect directly from the source:

```bash
cargo install kimspect
```

### Using Homebrew (macOS)

If you are on macOS and use Homebrew, you can install kimspect via our tap:

```bash
brew tap koithos/cli/kimspect
brew install kimspect
```

### Using Krew (kubectl Plugin Manager)

If you use `kubectl` and have Krew installed, you can install kimspect as a kubectl plugin:

```bash
kubectl krew install kimspect
```

## Usage

### Get image details with multiple filters

```bash
# List Pod Images in a Namespace
kimspect get images --namespace default

# List Pod Images on a Specific Node
kimspect get images -N node-name
# or
kimspect get images --node node-name

# Note: When using the `--node` flag, the `--namespace` parameter is ignored as it will show pods from all namespaces on the specified node.

# List Images for a Specific Pod
kimspect get images -p pod-name
# or
kimspect get images --pod pod-name

# You can combine filters to get more specific results. For example, to get images for a specific pod on a specific node:
kimspect get images -N node-name -p pod-name

# List images from all namespaces
kimspect get images --all-namespaces

# Filter images by registry
kimspect get images --registry "docker.io" --namespace kube-system

# Show all images EXCEPT from docker.io
kimspect get images --exclude-registry "docker.io" --all-namespaces

# Show all images EXCEPT from specific node
kimspect get images --exclude-registry "docker.io" -n kube-system -o wide

# Filter images by registry in a specific node
kimspect get images --registry "quay.io" --node node-name

# Filter images by registry across all namespaces
kimspect get images --registry "quay.io" --all-namespaces

# Enable verbose logging
kimspect get images -v  # WARN
kimspect get images -vv  # INFO
kimspect get images -vvv  # DEBUG
kimspect get images -vvvv  # TRACE

# Use JSON log format
kimspect get images -vvv --log-format json
```

kimspect displays information in a clean tabular format:

```
kimspect get images -o wide

```

## Development

### Prerequisites

- Rust 1.85 or later
- Kubernetes cluster access
- `kubectl` installed & configured with your cluster

### Building from Source

```bash
# clone kimspect project
cd kimspect
cargo build --release
```

### Testing

kimspect includes comprehensive tests covering various aspects of the codebase. The tests are organized in the `tests` directory.

To run the tests:

```bash
# Run all tests
cargo test

# Run tests with output
cargo test -- --nocapture

# Run specific test
cargo test test_process_pod
```

## Releasing

This project uses `cargo-release` to automate the release process, ensuring that the version in `Cargo.toml` and the Git tag are synchronized.

### Prerequisites

1.  Install `cargo-release`:

```bash
    cargo install cargo-release
    ```

2.  Ensure your working directory is clean (all changes committed).
3.  Make sure you are on the main branch and have pulled the latest changes.

### Steps

- Run `bash scripts/cargo_release.sh <VERSION>` to update the version in the `Cargo.toml` file and create a Git tag.
- Once that is done, push the code to main, and a release workflow will be triggered which builds multi-platform binaries and distributes them via multiple channels.
