Table: kubernetes_ingress - Query Kubernetes Ingresses using SQL

Kubernetes Ingress is a collection of routing rules that govern how external users access services running in a Kubernetes cluster. Typically, these rules are used to expose services to external traffic coming from the internet. It provides a way to manage external access to the services in a cluster, typically HTTP.

Table Usage Guide

The kubernetes_ingress table provides insights into Ingresses within Kubernetes. As a DevOps engineer, explore Ingress-specific details through this table, including host information, backend service details, and associated annotations. Utilize it to uncover information about Ingresses, such as those with specific routing rules, the services they expose, and their configurations.

Examples

Basic Info

Explore which Kubernetes ingress resources are associated with specific namespaces and classes, and how long they have been created. This can help in tracking resource allocation and usage over time.

select
  name,
  namespace,
  ingress_class_name as class,
  age(current_timestamp, creation_timestamp)
from
  kubernetes_ingress
order by
  namespace,
  name;

select
  name,
  namespace,
  ingress_class_name as class,
  (julianday('now') - julianday(creation_timestamp)) * 24 * 60 * 60 as age
from
  kubernetes_ingress
order by
  namespace,
  name;

View rules for the ingress

Explore which ingress rules are currently in place within your Kubernetes environment. This can help in understanding and managing traffic routing, ensuring efficient and secure communication between services.

select
  name,
  namespace,
  jsonb_pretty(rules) as rules
from
  kubernetes_ingress;

select
  name,
  namespace,
  rules
from
  kubernetes_ingress;

List manifest resources

Explore which Kubernetes ingress resources are configured with a specific path. This can help identify areas where traffic routing rules have been established, which is essential for understanding and managing application traffic flow.

select
  name,
  namespace,
  ingress_class_name as class,
  path
from
  kubernetes_ingress
where
  path is not null
order by
  namespace,
  name;

select
  name,
  namespace,
  ingress_class_name as class,
  path
from
  kubernetes_ingress
where
  path is not null
order by
  namespace,
  name;

Schema for kubernetes_ingress

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.
default_backend	jsonb	A default backend capable of servicing requests that don't match any rule. At least one of 'backend' or 'rules' must be specified.
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.
ingress_class_name	text	Name of the IngressClass cluster resource. The associated IngressClass defines which controller will implement the resource.
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.
load_balancer	jsonb	a list containing ingress points for the load-balancer. Traffic intended for the service should be sent to these ingress points.
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.
rules	jsonb	A list of host rules used to configure the Ingress.
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.
tags	jsonb	A map of tags for the resource. This includes both labels and annotations.
title	text	Title of the resource.
tls	jsonb	TLS configuration.
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_ingress
