I’ve written a powershell script that install and configure an Octopus Server.
Can you please provide information on how I can do the same with “Configuring the Second and Additional Nodes” as defined in https://octopus.com/docs/administration/high-availability/configuring-octopus-for-high-availability
Hi @binh.au,
Thanks for getting in touch! I haven’t been able to find any specific script samples to configure an additional node, though a handy trick is to use the Show Script option in the wizard as you do some of this configuration manually. The following screenshot shows what this might look like, with the Show script option above the log output.
Does this help get you going? Let me know how you go or if you have any further questions going forward. 
Best regards,
Kenny
