The new Datadog Agent: Omnibus is your ticket out of dependency hell

The Datadog Agent, written in Python, faced challenges with its installation process due to varying versions of Python across different OS distributions and the need for third-party libraries. Before Agent 5.0, users had to manually install dependencies, which could lead to compatibility issues or conflicts with existing applications. To solve this problem, Datadog implemented Chef Omnibus, a tool that creates full-stack installers for projects across various platforms. The new build process combines Github, Jenkins, Vagrant, and S3 to create self-contained installer packages containing all the dependencies needed by the Agent. Upon installation, these dependencies are isolated in /opt/datadog-agent, ensuring compatibility with existing applications. This improvement allows users to add integrations and access new features more easily without worrying about dependency conflicts or issues related to different Python versions.
