Description

The tests found problems in dockerized environments since the template is not hosted in /etc/wazuh-indexer but in /usr/share/wazuh-indexer. The script must allow modifying the path for this use case and for custom packages where /etc/wazuh-indexer is not used

Tasks

• [x] Add an argument to modify the path in the execution of the script

Validation

• [x] https://github.com/wazuh/wazuh-automation/issues/1503
