[one-users] Context variables - getting username

[Nicolas AGIUS]

Hi

With this method, you have to add a NAME variable in every user template, which could become quickly boring.

I've done this in a more reliable way, and without patching or doing manual template modification, using the full xml template.

Example, in the context definiton :

CONTEXT=[

  FILES=init.sh,

  CTX_USER="$USER[TEMPLATE]"

]


And within the vm, in the init.sh script :

#!/bin/bash
source context.sh
username=$(echo $CTX_USER | base64 -d | xpath -e '/USER/NAME/text()' )


Cheers,
Nicolas AGIUS

Hi,

Yesterday I learned from ON developer Ruben that
for instance oneadmin can do
oneuser update ID(of the user who actually instantiates the VM template) 
which will open an editor where oneadmin can type in
NAME="the username you want".
This will enable $USER[NAME] to return "the username you want" in the CONTEXT.

Hope this helps.
