Inspired by geohot's minikeyval and SeaweedFS.
Python master server with leveldb which has key, values of filename, then a comma separated list of IP's of the volumes where that file is stored.
Run the docker containers of volumes:
docker run --name vol1 -p 33333:80 -d volume
docker run --name vol2 -p 33334:80 -d volumeThen run the master:
docker run --name master -p 8888:8080 -d master ./server.py -rep 2 -db /tmp/db -volumes 192.168.1.30:33333,192.168.1.30:33334When the master server opens it scans all the volumes to add to the leveldb.
Then you can use like so:
curl -X PUT -d "testVALUE" localhost:8888/testkey
# important to use -L so it follow the redirect to the volume
curl -L localhost:8888/testkey
=> testVALUE
