DTT1 - PoC - Allocation module

[fcaffieri]

Description

This issue aims to design and create a PoC of the allocation module.

This module is responsible for allocating the infrastructure resources (multi-provider).
This module will work as a black box where it will have a clear input and output.

• Input: A YAML file with all the necessary information about the necessary resources to be allocated.
• output: A YAML with the information of the resources allocated, with host, port and ssh keys.

The bases of the PoC are defined in the parent issue #4524.

Update

Design proposal - Functional aspects

• Commandline tool
• Allow allocating, getting current status, and cleaning up allocated resources in infrastructure platforms. Currently local Vagrant and AWS
• Easy integration for new providers
• Allow simple descriptions of resource requests and identification
  • Use human-readable identifications for resource OS
  • Use commonly used hashed IDs (UUID) for resource identification after being allocated
• Resources request file will be an array containing
  • composite-name: a well-defined string that will contain osfamilly-osdistro-osversion-osarch. ie linux-ubuntu-22.04-amd64
  • provider: aws/vagrant
  • role: already defined hardware specs grouped by "role". i.e agent/manager
  • alias: human-readable ID to refer to. Used on Ansible inventory output
• Allocation output will be an Ansible inventory file

Design proposal - Non-functional aspects

• Python as the default language
• YAML file as resource request input format
• Current tool state will be mixed, with a root working directory (/tmp/wazuh-infra by default )that will contain
  • A database containing already requested resources (needed to get current status and further resource deallocation)
  • A folder named with the UUID that will contain files related to the resource: Keys, Vagrantfiles, ...
• Basic testing suite is mandatory
• README with basic stuff

Update

This issue was on-hold from Nov 29 to Dec 5 due to:

• https://github.com/wazuh/wazuh-jenkins/issues/5927
• Logcollector scanning IT: The ValueError was raised when attempting to stop the 'wazuh-logcollector' daemon #4733
  Updating ETA to Dec 6 in order to get conclusion based on PoC performance and feedback

The PoC was finalized and presented to the interested parties, the DTT work will continue from other issues.
