Kubernetes tls certificate issier not issuing
Just to let you know what was the original cause of the problem: somehow, and we still don't know how, the content of file holding the certificate on one of the master nodes (/srv/kubernetes/ca.crt) had its content duplicated. Strange... During troubleshooting we tested that certificate using openssl which read that without any issues and that mislead us assuming it has to be OK...
Fixing the content by hand immediately fixed this problem.
Anyone else facing this issue? i've checked my ca.crt files on the 3 masters and it seems to be fine. But all my csr are in pending state
