Maybe you could look into LPIC DevOps Tools Engineer. https://www.lpi.org/our-certifications/devops-overview
I think is pretty new because there are no study books ready. When buying LPIC-101 and LPIC-102 exam vouchers I got the DevOps tools voucher for free but it seems there’s a lot of study to pass the exam, since there are plenty of technology and tools involved, from Ansible to K8/Docker Swarm, etc. However I think this is a good base for understanding the devops world and be confident with contemporary and future tools.
