Re: OCP 4.2 setup -


I am facing the issue of time synchronization between Openshift Web console with Bastion or other servers nodes. 
Openshift console is one hour ahead from bastion and other nodes .

Why it happens and how can i synchronize?

Cool, thanks! 

Before deploying the OCP cluster that uses UPI, It is needed configuration of DHCP , LB and DNS. 
I am interested to know which is :

a) Which is DNS best practice for offine installation?
   For DNS server , it is better to use Openshift DNS server or External DNS (for example, company DNS ) ?

OpenShift 4.x needs an external DNS provider for the records mentioned in the instructions: https://docs.openshift.com/container-platform/4.2/installing/installing_bare_metal/installing-restricted-networks-bare-metal.html#installation-dns-user-infra_installing-restricted-networks-bare-metal

It does run DNS inside the cluster too, but that is separate.

b) Which is DHCP best practice ? Which is better approach ?

Not sure what you're asking here, any DHCP server is fine as long as it can hand out static ip addresses (probably all DHCP servers).

c) Which is LB/SSL-Offloading best practice ?
   Using SSL offLoading, how is better the approach of LB ?
   - to have LB in front of OCP Cluster or LB inside Openshift ? 

You most likely do not want to do SSL-offloading, just do TCP load balancing (layer 4) as mentioned in the instructions.


OpenShift runs it's own SSL (in most circumstances), so doing offloading doesn't make all that much sense, especially when you're just learning OpenShift.

Thanks & Regards,

Now that we have official docs [1], it's better to use them instead of
the early blog post.  Not sure if they talk about subnet division
