Posted on by
OKD 4.9.0

It’s the most stable OKD version I’ve ever seen.

⚠️My personal suggestion would be to only use “Red Hat Openshift” for “Production and Live Environments” for sure ! – However, it is appropriate to use OKD for Test and Developer environments or for R&D. Of course it’s up to you..
