Build filter for twistlock namespace

{
  "query": {
    "match_phrase": {
      "kubernetes.namespace_name": "twistlock"
    }
  }
}

There should be 4 pods in the twistlock namespace

kubectl get pods -n twistlock
NAME                                READY   STATUS    RESTARTS   AGE
twistlock-console-random-number      1/1     Running   0          3h13m
twistlock-defender-random-number     1/1     Running   0          5s
twistlock-defender-random-number     1/1     Running   0          5s
twistlock-defender-random-number     1/1     Running   0          5s

:warning: CAUTION: If you only have one pod in the twistlock namespace, the defender did not install properly or at all. Run the steps to install defender again before continuing.

Here are some examples of a filter for specific containers

twistlock-console

{
  "query": {
    "match_phrase": {
      kubernetes.container_name:twistlock-console
    }
  }
}

twistlock-defender

{
  "query": {
    "match_phrase": {
      kubernetes.labels.app:twistlock-defender
    }
  }
}

In the KQL field you can text search within a source field such as twistlock-defender

kubernetes.labels.app: "twistlock-defender"
