nfs in cloudmesh-pi-cluster

• [x] (high priority) allow --username== in commandline so you can set username [default: pi]
• [x] (medium priority) find out how to pass to pytest --username= and --hostname=
  • [x] document how to
  • [x] pytest on specified hostnames
  • [x] we can assume if --username not specified username is pi
  • [x] we can assume that if --hostname is not specified its red

introducing pytest to create your nfs with an easy one-liner. this command creates a shared file system nfs and distributes it to workers. it creates the nfs in a folder called Stuff located on manager at ~/Stuff.

https://github.com/cloudmesh/cloudmesh-pi-cluster/blob/nfs/tests/test_nfs.py

do (ENV3) pi@red:~cm/cloudmesh-pi-cluster $ pytest -v --capture=no tests/test_nfs.py --username=pi --hostname=red,red0[1-3]

you can even leave out --username and --hostname so that username defaults to pi, and hostname defaults to red,red0[1-2]

this has parameters that are passed to pytest. you can change these parameters.

we are able to accomplish this with conftest.py. https://github.com/cloudmesh/cloudmesh-pi-cluster/blob/nfs/tests/conftest.py

This pytest uses the cms pi nfs commands to install an nfs file system available on every node. It uses username and hostname parameters to test the installation with such parameters.
