Podman discovery

[Michael Lineba2]

Looking to see if anyone has a successful discovery of podman and has suggestions of how to do so.     Since it assigns ports dynamically and does not have a process running on the server I am finding it challenging.

Any suggestions would be appreciated.

Hello @Michael Lineba2,

Discovering Podman within a ServiceNow environment presents challenges due to its dynamic port assignment and the lack of a central process running on the server. However, several approaches can be taken to achieve successful discovery: 

1. Leverage Existing Discovery Patterns:

• Extend Windows OS - Servers Pattern:

  While primarily designed for Windows servers, this pattern might be adaptable to identify Podman containers by analyzing processes within the host operating system. 
• Discovery Task Simulator 9.1:

  This tool can help simulate discovery tasks and test the effectiveness of various configurations. 
• Custom Discovery Script:

  Develop a custom script using scripting languages within ServiceNow to directly query Podman's API or analyze relevant logs. 

2. Focus on Port Mapping and Network Traffic:

• Identify Ports Used by Podman:

  While Podman assigns ports dynamically, understand which port ranges are typically used for containerized applications. 
• Analyze Network Traffic:

  Use tools within ServiceNow to monitor network traffic on the host server and identify patterns related to Podman containers. 
• Use Dynamic Port Discovery:

  ServiceNow offers features to detect dynamically assigned ports. Explore how these features might be used in conjunction with other discovery methods. 

3. Utilize the Podman API:

• Access Podman API:

  Podman provides an API that allows for programmatic access to container information, including ports, running processes, and more.
• Integrate API Calls:

  Create ServiceNow scripts that call the Podman API to retrieve information about containers.
• Extract Relevant Data:

  Use the API to extract the necessary information, such as container names, container IDs, and the ports they are listening on. 

4. Collaborate with the ServiceNow Community:

• Idea Portal:

  Submit a request to ServiceNow's Idea Portal to suggest enhancements to ServiceNow's discovery capabilities.
