# kube-query

kube-query is an extension for [osquery](https://osquery.io), letting you visualize your cluster using sql queries.

Deployment

===

### Prerequisites

#### Go v1.12+

### build

```bash

$ export GO111MODULE=on 

$ go build kube-query.go 

```

## Running kube-query

**When running kube-query, you should always pass the `-kubeconfig` flag, specifying the path to your kubeconfig file.**

## osqueryi 

When using the [osqueryi tool](https://osquery.readthedocs.io/en/stable/introduction/using-osqueryi/) you can easily register kube-query by passing the -socket parameter to kube-query on another process. For example:  

`./kube-query -socket="/path/to/osquery/socket" -kubeconfig="/path/to/kubeconfig.yml"` 

One way to get the path to the osquery socket is like this:

```

osqueryi --nodisable_extensions

osquery> select value from osquery_flags where name = 'extensions_socket';

+-----------------------------------+

| value                             |

+-----------------------------------+

| /Users/USERNAME/.osquery/shell.em |

+-----------------------------------+

```

There are many other options to automatically [register extensions](https://osquery.readthedocs.io/en/stable/deployment/extensions/).

Example Queries

# query all kube-system pods

SELECT * FROM kubernetes_pods WHERE namespace="kube-system";

# query all containers created by kubernetes

SELECT * FROM kubernetes_containers;

# query all pods that runs with a privileged container   

SELECT * 

 FROM kubernetes_containers 

 JOIN kubernetes_pods 

 ON kubernetes_containers.pod_uid=kubernetes_pods.uid

 WHERE privileged="True";

```
