module for bonfire to connect with sfa (following the Rspec)
inspired by the following documenation:
https://svn.planet-lab.org/wiki/SfaDeveloperDummyTutorial#RunningSFAinDummyflavour
does not forget to launching this code:
python /usr/lib/python2.7/site-packages/sfa/dummy/dummy_testbed_api.py
documentation
http://wiki.bonfire-project.eu/index.php/FED4FIRE_sfa
1 - list resources
2 - allocate
3 - provisioning
4 - create compute VM for fr-inria/uk-epcc
1) list all the resources of bonfire from sfa's point of view
python -c 'import bonfire; print bonfire.bonsources()'
2) allocate: create an experiment bonfire with slice information (parameters : user_name, groups, description, walltime, slice_name)
python -c 'import bonfire; print bonfire.allocate("nlebreto", "nlebreto", "tdes", "125", "topdomain.dummy.nicolas")'
3) provisioning: changing the status to running status for the experiment 2911
python -c 'import bonfire; print bonfire.provisioning("2911","running")'
4) bonfire create virtual machine with these specific features 1) fr-inria storages n°1805 network 2 ip public 2) uk-epcc storages n°1364 network 0 bonfire wan
python -c 'import bonfire; print bonfire.create_vm("fr-inria", "56910", "rester", "nlebreto")'
python -c 'import bonfire; print bonfire.create_vm("uk-epcc", "56910", "rester", "nlebreto")'
5) retrieve the url, the name and the key for a compute N°3656 located at fr-inria
python -c 'import bonfire; print bonfire.rsa_user_bonfire("fr-inria", "3656")'
6) create a new user and slice for sfa wrap
python -c 'import bonfire; print bonfire.new_user_slice()'
7) stop virtual machine in bonfire testbed (ex n°3756 at fr-inira testbed)
python -c 'import bonfire; print bonfire.stop_vm("fr-inria", "3756")'
8) remove slice or key
python -c 'import bonfire; print bonfire.remove_slice("topdomain.dummy.alice_slice")'
9) attach slice to a user
python -c 'import bonfire; print bonfire.create_slice_attach_user("topdomain.dummy.alice")'
10) verify bonfire authentication
python -c 'import bonfire; print bonfire.callcurl("https://api.bonfire-project.eu/")'
11) bonfire ldap authentification
python -c 'import bonfire; print bonfire.bonldap("nicolas.lebreton@inria.fr")'
