checkinvt.py - Deployment Inventory Checker Script
- Juan Tomás Alonso Nieto (Deactivated)
Overview
Since Endpoint Agent 1.2.1, the Deployment Inventory Checker Script is provided with the EA deployment package. The objective of this tool is to simplify and help the user understand how to properly use the inventory file, as well as to make sure that nothing unexpected occurs during the playbook run.
Prerequisites
The tool requires ansible to be installed on the system.
How to use it
Example syntax (from devo-ea-deployerfolder):

You can use python3 or python depending on the python version installed on your system. You can check what python version is associated with your ansible using ansible --version.
Deployment checks
The Deployment Inventory Checker Script performs the following checks:
YAML structure.
Existence of all, hosts, children and vars main sections.
Checks that main variables have the value of the correct type.
Default packs. Triggers a warning if no packs are enabled.
Checks user and passwords for WebUI and agent repository. Triggers a warning if the default users/pw are used.
Checks passwords for MySQL. Triggers a warning if the default password is used.
Checks passwords for REDIS. Triggers a warning if the default password is used (Redis does not use password by default).
Checks that all children host groups are defined correctly.
Checks that Devo certs are placed in the correct folder and with the correct name.
Checks SSH connectivity from the ansible host to every host defined in the inventory.
Checks hostname of every host and triggers a warning if the hostname is going to be changed.
Checks if
firewalld / ufwautomatic configuration is disabled and triggers a warning if so.
Deployment summary
The Deployment Inventory Checker Script provides the following summary:
Hosts summary: Configuration provided for each host.
Groups summary: Hosts included in each group, defining what is going to be installed in what host.
Internal Services connection properties: Shows connection string for MySQL and REDIS, username and database. In REDIS, it specifies if it runs with password or not.
Packs summary: Packs that are enabled and will be deployed.
Service URLs: URLs to access the service and the agent repository.
Example output
This is an example output of an inventory file where:
Default user/pw are in use for repo and WebUI.
Default MySQL password is in use.
REDIS is not using passwords.
