Customizing image with ssh key and static ip to be installed on multiple boards

[Stefanita Vilcu]

Hello, 

 

I am planning to create a Kubernetes cluster from 5 Raspberry PI and one of the alternatives mentioned in tags, 9 hosts in total. 

I want to mount and customize the installation images with ssh keys, static IP address, etc, and to skip the initial script offered at login by the CLI images.

Can you point me to the right piece of documentation? 

 

Thank you,

Hi Stefanita,

 

I wanted to do something similar with a few HC4's (also to run Kubernetes, incidentally ). I settled on this:

 

- Install authorized_keys in the image using customize-image.sh - https://docs.armbian.com/Developer-Guide_User-Configurations/#user-provided-image-customization-script

- SSH to each sbc after first boot, enter a root password and then cancel the rest of the setup script. It looked to me like the script does some important things before that point.

- Configure the rest with Ansible.

 

 

If you found a better way to boot non-interactively I'd be happy to hear!

 

Best regards,

Oscar

This is exactly what I was looking for.
