I’ve setup an infrastructure for our company’s websites with docker swarm (for now we are testing it with only 2 nodes: one manager and one worker. I know that is too little, but now its only for testing).
For now we have 10 stacks (3 on manager, 7 on worker)
Every container running on the worker-node has its storage volume mounted from an NFS server.
The total amount of the GB for all the stacks on the NFS server is 5GB.
Now, I don’t understand why the worker-node has filled 11GB on its hard disk…
The only bigger folder that i see on the worker node is “/var/lib/docker/overlay2/”…
How its possible??
Here some info:
– Ubuntu 18.04
– Docker version 18.09.6
– NFS docker-compose.yml config example:
volumes: www: driver_opts: type: nfs4 o: addr=192.168.1.13,nolock,soft,rw device: :/var/nfs/storage/website_1/www
