In order to delegate your credentials to the OneLab portal, you need to install SFA tools.
[Requirement: python 2.7 or higher]
$ sudo easy_install pip
$ sudo pip install sfa
Please download get-pip.py
$ python get-pip.py
$ pip install sfa
To get more information about pip, please visit: https://pip.pypa.io/en/latest/installing.html
More details about SFA is available at the following address: Installing SFA
Once SFA tools are successfully installed, you need to configure the SFA client aka SFI
$ mkdir ~/.sfi
$ cd ~/.sfi
$ cp ~/.ssh/id_rsa ~/.sfi/user-hrn.pkey
Here, 'user-hrn' is your SFA hrn. If e.g., your OneLab account email is mohammed-yasin.rahman at upmc.fr, then your user-hrn is 'onelab.upmc.mohammed-yasin_rahman'.
In this example, a user-hrn is built using the root authority i.e, 'onelab' followed by a '.' then the sub authority i.e., 'upmc' followed by a '.' and then the last fragment in the hrn is made of the local part of your email adress i.e., 'mohammed-yasin_rahman' (with dots replaced with underscores).
Next, you will setup your ~/.sfi/sfi_config. The following represents the sfi_config file for a OneLab user:
[sfi]
auth = onelab.upmc
user = onelab.upmc.mohammed-yasin_rahman
registry = http://portal.onelab.eu:12345/
sm = http://sfa3.planet-lab.eu:12346/
Here again, 'user' is your user-hrn, and 'auth' is the authority that you belong to, in most cases you should just drop the last part of your hrn.
Add the the following to sfi_config for delegating credentials to OneLab portal:
[myslice]
backend = http://portal.onelab.eu:7080
delegate = onelab.myslice
platform = myslice
username = mohammed-yasin.rahman@lip6.fr
Test the SFA layer:
$ sfi.py version
And finally delegate your credentials to the portal
$ sfi.py myslice
