Install

Note: Python 2.7 is needed. Python 3.x is not supported.

git clone https://github.com/mhristache/ipa
cd ipa
python virtualenv venv
source venv/bin/activate
pip install -r requirements.txt

Use

To create the IP plan first time, run ipa with the input yaml file as argument and with --first-run flag set:

./ipa.py --first-run INPUT.yaml

If the input file needs to be modified (e.g. more entries added) after the IP plan was used, the current IP plan in json format should be provided as input to ipa to make sure the currently allocated IPs are kept unchanged.

# save the original IP plan in json format
./ipa.py --first-run INPUT.yaml -o json > previous_allocation.json

# modify the input file

# create an updated IP plan that keeps the old entries unchanged
./ipa.py INPUT.yaml -p previous_allocation.json

# save a new 'previous' file
./ipa.py INPUT.yaml -p previous_allocation.json -o json > previous_allocation.json_new
mv previous_allocation.json_new previous_allocation.json

Note: currently it's only supported to add new entries to an IP plan. It's not supported to modify or delete existing entries.
