The topic of certificates seems to be haunting me at the moment.
Anyway, I want to briefly show here how easy it is nowadays to replace the SSL certificate of the vCenter with an Enterprise CA-signed one.
If you look at the KB article from VMware (Replacing a vSphere 6.x /7.x Machine SSL certificate with a Custom Certificate Authority Signed Certificate), the “certificate-manager” is still quoted here on the command line.
Create CSR in vSphere Client
But it is also very easy via the vSphere Client. In my case, there are a couple of VxRail clusters connected to this vCenter, here you also have to do something in the VxRail Manager (in this case still via CLI), but it’s also easy, see below.
To the Demo!
