Table: kubernetes_secret - Query Kubernetes Secrets using SQL

Kubernetes Secrets is a resource that manages sensitive data such as passwords, OAuth tokens, ssh keys, etc. It provides a more secure and flexible solution to manage sensitive data in a Kubernetes cluster, compared to the alternative of putting this information directly into pod specification or in docker images. Kubernetes Secrets offers the ability to decouple sensitive content from the pod specification and isolate the visibility of such sensitive information to just the system components which require access to it.

Table Usage Guide

The kubernetes_secret table provides insights into Kubernetes Secrets within a Kubernetes cluster. As a DevOps engineer, explore secret-specific details through this table, including the type of secret, the namespace it belongs to, and associated metadata. Utilize it to uncover information about secrets, such as those that are not in use, those that are exposed, or those that are stored in a non-compliant manner.

Examples

Basic Info

Explore the age and details of various Kubernetes secrets to understand their creation and configuration for better resource management and security. This could be particularly useful in identifying outdated or potentially vulnerable secrets that may need updating or removal.

select
  name,
  namespace,
  data.key,
  data.value,
  age(current_timestamp, creation_timestamp)
from
  kubernetes_secret,
  jsonb_each(data) as data
order by
  namespace,
  name;

select
  name,
  namespace,
  data.key,
  data.value,
  (julianday('now') - julianday(creation_timestamp)) * 24 * 60 * 60
from
  kubernetes_secret,
  json_each(data) as data
order by
  namespace,
  name;

List and base64 decode secret values

Explore the decoded values of secrets in your Kubernetes environment to better understand the information they hold. This can be particularly useful for troubleshooting or auditing purposes.

select
  name,
  namespace,
  data.key,
  decode(data.value, 'base64') as decoded_data,
  age(current_timestamp, creation_timestamp)
from
  kubernetes_secret,
  jsonb_each_text(data) as data
order by
  namespace,
  name;

select
  name,
  namespace,
  data.key,
  data.value as decoded_data,
  julianday('now') - julianday(creation_timestamp)
from
  kubernetes_secret,
  json_each(data) as data
order by
  namespace,
  name;

List manifest resources

Explore which encrypted data is associated with each resource in your Kubernetes environment. This can help you assess the elements within your system configuration and identify potential areas of concern.

select
  name,
  namespace,
  data.key,
  data.value,
  path
from
  kubernetes_secret,
  jsonb_each(data) as data
where
  path is not null
order by
  namespace,
  name;

select
  name,
  namespace,
  data.key,
  data.value,
  path
from
  kubernetes_secret,
  json_each(data) as data
where
  path is not null
order by
  namespace,
  name;

Schema for kubernetes_secret

Name	Type	Description
_ctx	jsonb	Steampipe context in JSON form, e.g. connection_name.
annotations	jsonb	Annotations is an unstructured key value map stored with a resource that may be set by external tools to store and retrieve arbitrary metadata.
context_name	text	Kubectl config context name.
creation_timestamp	timestamp with time zone	CreationTimestamp is a timestamp representing the server time when this object was created.
data	jsonb	Contains the secret data.
deletion_grace_period_seconds	bigint	Number of seconds allowed for this object to gracefully terminate before it will be removed from the system. Only set when deletionTimestamp is also set.
deletion_timestamp	timestamp with time zone	DeletionTimestamp is RFC 3339 date and time at which this resource will be deleted.
end_line	bigint	The path to the manifest file.
finalizers	jsonb	Must be empty before the object is deleted from the registry. Each entry is an identifier for the responsible component that will remove the entry from the list. If the deletionTimestamp of the object is non-nil, entries in this list can only be removed.
generate_name	text	GenerateName is an optional prefix, used by the server, to generate a unique name ONLY IF the Name field has not been provided.
generation	bigint	A sequence number representing a specific generation of the desired state.
immutable	boolean	If set to true, ensures that data stored in the Secret cannot be updated (only object metadata can be modified). If not set to true, the field can be modified at any time. Defaulted to nil.
labels	jsonb	Map of string keys and values that can be used to organize and categorize (scope and select) objects. May match selectors of replication controllers and services.
name	text	Name of the object. Name must be unique within a namespace.
namespace	text	Namespace defines the space within which each name must be unique.
owner_references	jsonb	List of objects depended by this object. If ALL objects in the list have been deleted, this object will be garbage collected. If this object is managed by a controller, then an entry in this list will point to this controller, with the controller field set to true. There cannot be more than one managing controller.
path	text	The path to the manifest file.
resource_version	text	An opaque value that represents the internal version of this object that can be used by clients to determine when objects have changed.
source_type	text	The source of the resource. Possible values are: deployed and manifest. If the resource is fetched from the spec file the value will be manifest.
start_line	bigint	The path to the manifest file.
string_data	jsonb	Contains the configuration binary data.
tags	jsonb	A map of tags for the resource. This includes both labels and annotations.
title	text	Title of the resource.
type	text	Type of the secret data.
uid	text	UID is the unique in time and space value for this object.

Export

This table is available as a standalone Exporter CLI. Steampipe exporters are stand-alone binaries that allow you to extract data using Steampipe plugins without a database.

You can download the tarball for your platform from the Releases page, but it is simplest to install them with the steampipe_export_installer.sh script:

/bin/sh -c "$(curl -fsSL https://steampipe.io/install/export.sh)" -- kubernetes

You can pass the configuration to the command with the --config argument:

steampipe_export_kubernetes --config '<your_config>' kubernetes_secret
