This repo holds custom callback plugin, so your Ansible could write everything in the PostgreSQL database.

Overview

English

What is it?

This is callback plugin that dumps most of the Ansible internal state to the external PostgreSQL database.

What is this for?

If you ever had to:

  • know the value of the certain variable before the role or task starts;
  • implement an audit soultion which should send data to some remote storage for unchangeability;
  • investigate into some Ansible function while dreaming of looking under the hood

...then this plugin is right for you.

Requirements

  • CentOS/RHEL 7.x;
  • Ansible 2.9.x;
  • Python >=3.6.x;
  • PostgreSQL >=10.x (this was debugged with Postgres 12, though)

Quick start guide

  1. Copy to your project directory:
    1. playbooks/callback_plugins/logdb.py
    2. playbooks/module_utils/pg8000/*
    3. playbooks/module_utils/scramp/*
  2. Add settings to the ansible.cfg as follows:
[defaults]
stdout_callback = log2db
callable_plugins = log2db
callback_whitelist = log2db

[log2db_callback]
host = <your PostgreSQL server hostname>
port = <your PostgreSQL server port, usually 5432>
user = <database account with insert privilege>
pass = <database account password>
db = <database name, default is "ansible">
table = <table name, default is "logs">
  1. Do not forget to setup a database and a table before the first launch. Also, an account with proper rights is a must:
[[email protected]]> sudo -u postgres psql
postgres=# CREATE DATABASE <my_db_name> WITH OWNER postgres;
postgres=# CREATE USER <my_db_user>;
postgres=# GRANT CONNECT, CREATE, TEMPORARY ON DATABASE <my_db_name> to <my_db_user>;
postgres=# CREATE TABLE IF NOT EXISTS <my_table_name> (
   uuid uuid not null,
   data jsonb,
   timestamp timestamp with time zone,
   id bigserial
   constraint logs_pk
   primary key,
   origin text);
postgres=# ALTER TABLE <my_table_name> OWNER to <my_db_account>;
postgres=# CREATE INDEX IF NOT EXISTS <my_table_name>_uuid_index on <my_table_name> (uuid);
postgres=# ALTER USER <my_db_user> WITH PASSWORD '<my_db_password>';

Что это?

Коллбэк-плагин для Ansible, который позволяет сохранять бОльшую часть внутренних данных Ansible во внешнюю БД.

Зачем это?

Если тебе когда-нибудь:

  • требовалось при отладке знать значение конкретной переменной перед исполнением таска или вызовом роли;
  • приходилось организовывать аудит с сохранением данных в отдельном от Ansible внешнем хранилище;
  • случалось разбираться с какой-то функций Ansible в мечтах о возможности "заглянуть под капот" -

...то этот плагин - для тебя.

Что требуется?

  • CentOS/RHEL 7.x;
  • Ansible 2.9.x;
  • Python >=3.6.x;
  • PostgreSQL >=10 (отлаживалось на 12);

Как запустить?

  1. Скопируй в каталог с проектом:
    1. playbooks/callback_plugins/logdb.py
    2. playbooks/module_utils/pg8000/*
    3. playbooks/module_utils/scramp/*
  2. Укажи в ansible.cfg следующее:
[defaults]
stdout_callback = logdb
callable_plugins = logdb
callback_whitelist = logdb

[logdb_callback]
host = <имя хоста PostgreSQL>
port = <порт сервера PostgreSQL, обычно 5432>
user = <учётная запись в БД с правами на INSERT>
pass = <пароль этой учётной записи>
db = <название БД, по умолчанию "ansible">
table = <название таблицы, по умолчанию "logs">
  1. Перед запуском не забудь создать БД и таблицу. А ещё понадобится создать учётку и дать ей права:
[[email protected]]> sudo -u postgres psql
postgres=# CREATE DATABASE <название БД> WITH OWNER postgres;
postgres=# CREATE USER <учётная запись>;
postgres=# GRANT CONNECT, CREATE, TEMPORARY ON DATABASE <название БД> to <учётная запись>;
postgres=# CREATE TABLE IF NOT EXISTS <название таблицы> (
   uuid uuid not null,
   data jsonb,
   timestamp timestamp with time zone,
   id bigserial
   constraint logs_pk
   primary key,
   origin text);
postgres=# ALTER TABLE <название таблицы> OWNER to <учётная запись>;
postgres=# CREATE INDEX IF NOT EXISTS <название таблицы>_uuid_index on <название таблицы> (uuid);
postgres=# ALTER USER <учётная запись> WITH PASSWORD '<пароль учётной записи>';
