In “SQL: The Common Solvent for REST APIs” we noticed how Steampipe’s suite of open supply plug-ins that translate REST API calls immediately into SQL tables. These plug-ins had been, till lately, tightly certain to the open supply engine and to the occasion of Postgres that it launches and controls. That led members of the Steampipe neighborhood to ask: “Can we use the plug-ins in our personal Postgres databases?” Now the reply is sure—and extra—however let’s deal with Postgres first.
Utilizing a Steampipe Plugin as a Standalone Postgres International Knowledge Wrapper (FDW)
Go to Steampipe downloads to seek out the installer in your OS, and run it to amass the Postgres FDW distribution of a plugin—on this case, the GitHub plugin. It’s considered one of (presently) 140 plug-ins obtainable on the Steampipe hub. Every plugin gives a set of tables that map API calls to database tables—within the case of the GitHub plugin, 55 such tables. Every desk can seem in a FROM
or JOIN
clause; right here’s a question to pick columns from the GitHub problem, filtering on a repository and creator.
choose
state,
updated_at,
title,
url
from
github_issue
the place
repository_full_name="turbot/steampipe"
and author_login = 'judell'
order by
updated_at desc
Should you’re utilizing Steampipe, you possibly can set up the GitHub plugin like this:
steampipe plugin set up github
then run the question within the Steampipe CLI or in any Postgres shopper that may hook up with Steampipe’s occasion of Postgres.
However if you wish to do the identical factor in your personal occasion of Postgres, you possibly can set up the plugin another way.
$ sudo /bin/sh -c "$(
curl -fsSL https://steampipe.io/set up/postgres.sh)"
Enter the plugin identify: github
Enter the model (newest):
Found:
- PostgreSQL model: 14
- PostgreSQL location: /usr/lib/postgresql/14
- Working system: Linux
- System structure: x86_64
Based mostly on the above, steampipe_postgres_github.pg14.linux_amd64.tar.gz
shall be downloaded, extracted and put in at: /usr/lib/postgresql/14
Proceed with putting in Steampipe PostgreSQL FDW for model 14 at
/usr/lib/postgresql/14?
- Press 'y' to proceed with the present model.
- Press 'n' to customise your PostgreSQL set up listing
and choose a unique model. (Y/n):

Efficiently put in steampipe_postgres_github extension!
Information have been copied to:
- Library listing: /usr/lib/postgresql/14/lib
- Extension listing: /usr/share/postgresql/14/extension/
Now hook up with your server as ordinary, utilizing psql
or one other shopper, most sometimes because the postgres
consumer. Then run these instructions, that are typical for any Postgres overseas information wrapper. As with all Postgres extensions, you begin like this:
CREATE EXTENSION steampipe_postgres_fdw_github;
To make use of a overseas information wrapper, you first create a server:
CREATE SERVER steampipe_github FOREIGN DATA WRAPPER
steampipe_postgres_github OPTIONS (config 'token="ghp_..."');
Use OPTIONS to configure the extension to make use of your GitHub entry token. (Alternatively, the usual atmosphere variables used to configure a Steampipe plugin—it’s simply GITHUB_TOKEN
on this case—will work should you set them earlier than beginning your occasion of Postgres.)
The tables supplied by the extension will stay in a schema, so outline one:
CREATE SCHEMA github;
Now import the schema outlined by the overseas server into the native schema you simply created:
IMPORT FOREIGN SCHEMA github FROM SERVER steampipe_github INTO github;
Now run a question!
The overseas tables supplied by the extension stay within the github schema
, so by default you’ll discuss with tables like github.github_my_repository
. Should you set search_path="github"
, although, the schema turns into optionally available and you may write queries utilizing unqualified desk names. Right here’s a question we confirmed final time. It makes use of the GitHub_search_repository which encapsulates the GitHub API for looking out repositories.
Suppose you’re on the lookout for repos associated to PySpark. Right here’s a question to seek out repos whose names match “pyspark” and report just a few metrics that can assist you gauge exercise and recognition.
choose
name_with_owner,
updated_at, -- how lately up to date?
stargazer_count -- how many individuals starred the repo?
from
github_search_repository
the place
question = 'pyspark in:identify'
order by

You probably have quite a lot of repos, the primary run of that question will take just a few seconds. The second run will return outcomes immediately, although, as a result of the extension features a highly effective and complex cache.
And that’s all there’s to it! Each Steampipe plugin is now additionally a overseas information wrapper that works precisely like this one. You may load a number of extensions with a view to be part of throughout APIs. In fact, you possibly can be part of any of those API-sourced overseas tables with your personal Postgres tables. And to avoid wasting the outcomes of any question, you possibly can prepend “create desk NAME as” or “create materialized view NAME as” to a question to persist outcomes as a desk or view.
Utilizing a Steampipe Plugin as a SQLite Extension That Gives Digital Tables
Go to Steampipe downloads to seek out the installer in your OS and run it to amass the SQLite distribution of the identical plugin.
$ sudo /bin/sh -c "$(curl -fsSL https://steampipe.io/set up/sqlite.sh)"
Enter the plugin identify: github
Enter model (newest):

Now you possibly can run the identical question as above. Right here, too, the outcomes are cached, so a second run of the question shall be immediate.
What concerning the variations between Postgres-flavored and SQLite-flavored SQL? The Steampipe hub is your pal! For instance, listed below are Postgres and SQLite variants of a question that accesses a area inside a JSON column with a view to tabulate the languages related along with your gists.
Postgres
SQLite
The github_my_gist desk studies particulars about gists that belong to the GitHub consumer who’s authenticated to Steampipe. The language related to every gist lives in a JSONB column referred to as recordsdata, which comprises a listing of objects like this.
{
"dimension": 24541,
"kind": "textual content/markdown",
"raw_url": "https://gist.githubusercontent.com/judell/49d66ca2a5d2a3b
"filename": "steampipe-readme-update.md",
"language": "Markdown"
}
The features wanted to mission that record as rows differ: in Postgres you employ jsonb_array_elements
and in SQLite it’s json_each
.
As with Postgres extensions, you possibly can load a number of SQLite extensions with a view to be part of throughout APIs. You may be part of any of those API-sourced overseas tables with your personal SQLite tables. And you may prepend create desk NAME as
to a question to persist outcomes as a desk.
Utilizing a Steampipe Plugin as a Standalone Export Device
Go to Steampipe downloads to seek out the installer in your OS, and run it to amass the export distribution of a plugin—once more, we’ll illustrate utilizing the GitHub plugin.

Faucet into the Steampipe Plugin Ecosystem
Steampipe plug-ins aren’t simply uncooked interfaces to underlying APIs. They use tables to mannequin these APIs in helpful methods. For instance, the github_my_repository
desk exemplifies a design sample that applies constantly throughout the suite of plug-ins. From the GitHub plugin’s documentation:
You may personal repositories individually, or you possibly can share possession of repositories with different individuals in a corporation. The
github_my_repository
desk will record repos that you simply personal, that you simply collaborate on, or that belong to your organizations. To question ANY repository, together with public repos, use thegithub_repository
desk.
Different plug-ins comply with the identical sample. For instance, the Microsoft 365 plugin gives each microsoft_my_mail_message
and microsoft_mail_message
, and the plugin gives googleworkspace_my_gmail_message
and googleworkspace_gmail
. The place potential, plug-ins consolidate views of sources from the attitude of an authenticated consumer.
Whereas plug-ins sometimes present tables with fastened schemas, that’s not all the time the case. Dynamic schemas, carried out by the Airtable, CSV, Kubernetes, and Salesforce plug-ins (amongst others) are one other key sample. Right here’s a CSV instance utilizing a standalone Postgres FDW.
IMPORT FOREIGN SCHEMA csv FROM SERVER steampipe_csv INTO csv
OPTIONS(config 'paths=["/home/jon/csv"]');
Now all of the .csv
recordsdata in /house/jon/csv
will automagically be Postgres overseas tables. Suppose you retain monitor of legitimate house owners of EC2 situations in a file referred to as ec2_owner_tags
. Right here’s a question in opposition to the corresponding desk.
choose * from csv.ec2_owner_tags;
proprietor | _ctx
----------------+----------------------------
Pam Beesly | {"connection_name": "csv"}
Dwight Schrute | {"connection_name": "csv"}
You possibly can be part of that desk with the AWS plugin’s aws_ec2_instance
desk to report proprietor tags on EC2 situations which might be (or usually are not) listed within the CSV file.
choose
ec2.proprietor,
case
when csv.proprietor is null then 'false'
else 'true'
finish as is_listed
from
(choose distinct tags ->> 'proprietor' as proprietor
from aws.aws_ec2_instance) ec2
left be part of
csv.ec2_owner_tags csv on ec2.proprietor = csv.proprietor;
proprietor | is_listed
----------------+-----------
Dwight Schrute | true
Michael Scott | false
Throughout the suite of plug-ins there are greater than 2,300 predefined fixed-schema tables that you should utilize in these methods, plus a vast variety of dynamic tables. And new plug-ins are always being added by Turbot and by Steampipe’s open supply neighborhood. You may faucet into this ecosystem utilizing Steampipe or Turbot Pipes, from your personal Postgres or SQLite database, or immediately from the command line.
