I would like to automate as much as possible with the ArcGIS Enterprise deployment. At the moment I have automated the basic deployment of ArcGIS Enterprise (on linux) using silent install scripts and python-scripts Esri made available, in combination with Ansible. Now I want to customize Portal by creating a homepage, federate a server etc. The idea is that in future deployments, we don't have to customize the Portal again. I could not find a single script where I can change settings of Portal, is there any way I can do this? Or do I have to do this via the web in Portal itself?
We are currently using ArcGIS Enterprise 10.6.1
I don't know of one to replace the home page, but Esri has chef scripts to handle most other tasks:
