Changing the IP Address of the Host and Manager

[YA1007]

Using temporary IP addresses, we performed the following tasks:
・Installed and configured the OS using the HVM OS installation ISO internally, followed by apt update and upgrade.
・Deployed the manager.

Before setting up the cluster, we would like to change the addresses to match the customer's address scheme. Is it acceptable to change the IP addresses of the host and manager after completing the above tasks?
Please also advise if there are any points to note.

*Apologies if the machine translation is unclear.

Hmm, interesting scenario. I’ve done something similar a couple of times, and changing IPs after setup can work, but you have to be careful with any references or configurations that might still point to the old addresses. Things like firewall rules DNS entries, or cluster configs could break if not updated.

Also, i wonder if this were on a managed environment like Arzhost would their setup tools handle some of this automatically, or would you still need to manually update everything? Just curious how others handle it.

Thank you for your reply.

I'm relieved to hear that changing the IP address at the timing I mentioned earlier will not cause any problems.

I'm currently testing the work using temporary IP addresses, but this is all being done automatically using Ansible.

I plan to change the IP address and hosts file manually.
This is because it is difficult to do this automatically in my environment.

I'll give it a try.
