Table: json_file - Query Config JSON Files using SQL

Config is a service that allows you to assess, audit, and evaluate the configurations of your config resources. It provides a centralized way to manage and evaluate configurations, including JSON files, across your config resources. Config helps you maintain the desired state of your resources and take appropriate actions when predefined conditions are met.

Table Usage Guide

The json_file table provides insights into JSON files within Config. As a DevOps engineer, explore file-specific details through this table, including content, file paths, and associated metadata. Utilize it to uncover information about JSON files, such as their content and location, and to verify the consistency of configuration data.

For instance, if json_paths is set to [ "/Users/myuser/*.json" ], and that directory contains:

invoice.json
test.json

This table will retrieve the file contents from each file mentioned above, which you can then query directly:

select
  path,
  jsonb_pretty(content) as file_content
from
  json_file;

Examples

Query a simple file

This query is useful for gaining insights into customer behavior by analyzing their purchase history. It enables you to identify the date of purchase, the customer's name, and the quantity of items ordered, which can be instrumental in understanding customer preferences and trends. Given the file invoice.json with the following configuration:

{
  "bill-to": null,
  "city": "East Centerville",
  "customer": { "family_name": "Gale", "first_name": "Dorothy" },
  "date": "2012-08-06T00:00:00Z",
  "items": [
    {
      "description": "Water Bucket (Filled)",
      "part_no": "A4786",
      "price": 1.47,
      "quantity": 4
    },
    {
      "description": "High Heeled \"Ruby\" Slippers",
      "part_no": "E1628",
      "price": 133.7,
      "quantity": 1,
      "size": 8
    }
  ],
  "receipt": "Oz-Ware Purchase Invoice",
  "ship-to": null,
  "state": "KS",
  "street": "123 Tornado Alley\nSuite 16\n"
}

You can query the customer details and the number of items ordered:

select
  content ->> 'date' as order_date,
  concat(
    content -> 'customer' ->> 'first_name',
    ' ',
    content -> 'customer' ->> 'family_name'
  ) as customer_name,
  jsonb_array_length(content -> 'items') as order_count
from
  json_file
where
  path = '/Users/myuser/invoice.json';

select
  json_extract(content, '$.date') as order_date,
  (
    json_extract(content, '$.customer.first_name') || ' ' || json_extract(content, '$.customer.family_name')
  ) as customer_name,
  json_array_length(json_extract(content, '$.items')) as order_count
from
  json_file
where
  path = '/Users/myuser/invoice.json';

+----------------------+---------------+-------------+
| order_date           | customer_name | order_count |
+----------------------+---------------+-------------+
| 2012-08-06T00:00:00Z | Dorothy Gale  | 2           |
+----------------------+---------------+-------------+

Casting column data for analysis

Determine the areas in which specific customer purchases can be analyzed. This allows for a detailed breakdown of individual transactions, including the customer's name, product descriptions, and the total cost of each item purchased. Text columns can be easily cast to other types:

select
  (content ->> 'date') :: timestamp as order_date,
  concat(
    content -> 'customer' ->> 'first_name',
    ' ',
    content -> 'customer' ->> 'family_name'
  ) as customer_name,
  item ->> 'description' as description,
  (item ->> 'price') :: float as price,
  (item ->> 'quantity') :: integer as quantity,
  (item ->> 'price') :: float * (item ->> 'quantity') :: integer as total
from
  json_file,
  jsonb_array_elements(content -> 'items') as item
where
  path = '/Users/myuser/invoice.json';

select
  datetime(json_extract(content, '$.date')) as order_date,
  json_extract(content, '$.customer.first_name') || ' ' || json_extract(content, '$.customer.family_name') as customer_name,
  json_extract(item.value, '$.description') as description,
  cast(json_extract(item.value, '$.price') as float) as price,
  cast(json_extract(item.value, '$.quantity') as integer) as quantity,
  cast(json_extract(item.value, '$.price') as float) * cast(json_extract(item.value, '$.quantity') as integer) as total
from
  json_file,
  json_each(json_extract(content, '$.items')) as item
where
  path = '/Users/myuser/invoice.json';

+---------------------+---------------+-----------------------------+-------+----------+-------+
| order_date          | customer_name | description                 | price | quantity | total |
+---------------------+---------------+-----------------------------+-------+----------+-------+
| 2012-08-06 00:00:00 | Dorothy Gale  | Water Bucket (Filled)       | 1.47  | 4        | 5.88  |
| 2012-08-06 00:00:00 | Dorothy Gale  | High Heeled "Ruby" Slippers | 133.7 | 1        | 133.7 |
+---------------------+---------------+-----------------------------+-------+----------+-------+

Schema for json_file

Name	Type	Operators	Description
_ctx	jsonb		Steampipe context in JSON form, e.g. connection_name.
content	jsonb		Specifies the file content.
path	text	=	Specifies the path of the JSON file.

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)" -- config

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

steampipe_export_config --config '<your_config>' json_file
