Canonical is actively working on a certification program. Ubuntu Server and Desktop to start with, but other areas will follow in the future. It’s not open just yet, but you can read more about it here and keep an eye out for when exams become available.
How about LXD Certification? How long can you wait for LXD certification to appear?
LXD has excellent documentation for learning (Nothing worse than Kubernetes), I think it is possible to make a certification similar to Kubernetes
There is a great product (LXD demo server https://snapcraft.io/lxd-demo-server
) I think it can be used for certification (having slightly adjusted for the exam)
It’s not on our priority list just yet so it won’t be available any time soon, but I will discuss it with the certification team and keep you posted on any news.
