Introduction

Getting started with hooks in Eenos

The  Eenos control panel support hooks, which will help you to integrate any custom scripts or code block in the middle of Eenos operations. 

Eenos support two type  of hooks  Pre Hooks and Post Hooks.

Pre Hooks

The pre hooks will be executed before the operation of a specific function. You should place the hook script in the following folder.

Location :   /var/eenos/hooks/FUNCTION_NAME/pre/   ,   where FUNCTION_NAME is the action function

Example :

 Example for a dns creation pre hook   : /var/eenos/hooks/dns/pre/01-dns_sync.py

Post Hooks

The post hooks will be executed  after the operation of a specific function . You should place the hook script in the following folder.

Location : /var/eenos/hooks/FUNCTION_NAME/post/  , where FUNCTION_NAME is the action function

Example :

 Example for a dns creation post hook :  /var/eenos/hooks/dns/post/01-dns_sync.py

All hooks scripts must need execute permission to run the program .

Hook Inputs

The Eenos system calls will send the following  command line inputs to  the  hook scripts.

  •  data  :  A base64 encoded JSON data of the related actions ,  This is compulsory.
  • action :  The action code  CREATE , UPDATE or DELETE  , This is compulsory
  • panel : The control panel that perform the hooks , wap. rapp or uapp , This is compulsory
  • domain : The domain name performing the hooks. It is optional
  • user :  The  Eenos user name associated with . It is optional

An example hook action will be look like as follows :

/var/eenos/hooks/dns/pre/01-test.py \
  data=eyJ0ZXN0IjoidGVzdCIsImhpIjoiaGVsbG8ifQ== \
  action=CREATE \
  panel=wap \
  domain=fun.com \
  user=foo

You may decode the data and process it. 

Hook Programming Languages

The  Eenos hook support any programming language or binary. The only requirement is that your need to provide execute permission for the hook scripts. We recommend to use Python scripts for creating  hooks.

Hooks Script Ordering

The  Eenos will sort the  hook scripts  based on the name . So if you like to execute  multiple hooks , please make sure the the hook scripts name in a sorted order.  ( eg : 00-pre.py , 01-pre.py, 02-pre.py )
