Speed up preflight container certification for large telco workloads by leveraging Ansible parallelization

September 27, 2024Andrew Vu, Tatiana Krishtop, PhD, Ying Wang
The certification of preflight for containers can be time-intensive, especially when testing at scale. This blog explores how leveraging Ansible's asynchronous processing and parallel execution can optimize Red Hat's certification workflows. By integrating these features into Distributed-CI (DCI), tasks such as CVE scanning, testing, and report submission can be executed in parallel, reducing certification times by up to 74% when tested with 20 container images. We provide insights into implementing these enhancements for efficient, large-scale CNF testing, aligning with Kubernetes best practices…read full post

Exploring Certification Test Suites Integrated in DCI: A Comprehensive Review

July 18, 2023Ramon Perez, Jose Alberto Rodriguez, Tatiana Krishtop, PhD
This post will focus on the certification test suites that Red Hat has created for cloud-native applications to verify their adherence to best practices. In particular, we will see how DCI can simplify the setup required for these suites by handling all of the work related to the preparation of the configuration for the test suites, execution of the suites and report of the results…read full post
