create_config.py -- helper script for prepping the Pi with dynamically generated ssh keys, IP addresses
Creates configuration for n hosts using installer-config.txt config file as template. It modifies the ssh-pub-key and ip_addr based on the host parameter. The generated ssh key and configuration file are stored in the directory with name as the last octet of the host's IP address.
Once the ssh file is created, it is also copied of the server directory so that it can be served to the students.
Example:
- parameters:
python create_config.py --help
usage: create_config.py [-h] [-hosts TOTAL_NODES] [-net NETWORK]
[-st START_FROM]
optional arguments:
-h, --help show this help message and exit
-hosts TOTAL_NODES total number of nodes for which the configuration needs
to be generated
-net NETWORK Network e.g. 192.168.1.0. Subnet is assumed to be /24
-st START_FROM start the host naming from. The nodes will be numbered
sequentially- To create 10 hosts with ip address starting from 192.168.1.50 - 192.168.1.60:
python create_config.py -hosts 10 -net 192.168.1.0 -st 50
