Simple and basic ipam implementation

basic-ipam

A very basic implementation of flask app used for storing a cidr address and checking for overlaps

# install deps
for x in $(cat bindep.txt); do echo $x ; sudo apt install -y $x ; done
sudo -H pip install -r requirements.txt

# run unit tests
sudo -H pip install tox && tox

# run in debug mode
H=0.0.0.0; P=8888
export FLASK_APP=ipam.py && FLASK_DEBUG=1 flask run --host $H --port $P --without-threads

Example REST calls:

sudo apt install -y jq

for currCidr in "2001:db8::/32" "1.1.1.4/31"; do \
  json=$(jq -n -r \
         --arg cidr "$currCidr" \
         '{cidr: $cidr}'
         )
  curl -H "Cache-Control: no-cache" -H "Content-Type: application/json" \
    -i -X POST -d "$json" http://localhost:8888/subnets
done

curl -i http://localhost:8888/subnets

curl -i http://localhost:8888/subnets?family=6

curl -i http://localhost:8888/subnet/1

# allocate address from existing subnet
json=$(jq -n -r '{subnet_id: 1}')
for _ in {1..3}; do \
   curl -H "Cache-Control: no-cache" -H "Content-Type: application/json" \
       -i -X POST -d "$json" http://localhost:8888/subnet_address
done

json=$(jq -n -r '{subnet_id: 2}')
for _ in {1..3}; do \
   curl -H "Cache-Control: no-cache" -H "Content-Type: application/json" \
       -i -X POST -d "$json" http://localhost:8888/subnet_address
done

# show allocations
curl -i http://localhost:8888/subnet_address/2

# de-allocate
json=$(jq -n -r '{subnet_id: 1, address: "2001:db8::1"}')
curl -H "Cache-Control: no-cache" -H "Content-Type: application/json" \
     -i -X DELETE -d "$json" http://localhost:8888/subnet_address

json=$(jq -n -r '{subnet_id: 2, address: "1.1.1.4"}')
curl -H "Cache-Control: no-cache" -H "Content-Type: application/json" \
     -i -X DELETE -d "$json" http://localhost:8888/subnet_address

# remove subnets and any remaining allocations
curl -i -X DELETE http://localhost:8888/subnet/1
curl -i -X DELETE http://localhost:8888/subnet/2
