Description

A Template Recipe would provide most/all of the vm template (CPU, VCPU, MEMORY, NIC, DISK, etc) with the user providing overrides that are allowed. Also default values could be defined in case the user does not include any:

NAME    = "${NAME}" 
CPU     = ${CPU:1.0}
VCPU    = ${CPU:1}
MEMORY  = ${MEMORY:512}
DISK    = [ 
    IMAGE="${DISK_OS:CentOS Server}",
    DRIVER=qcow2,
    CACHE=none 
]

onetemplate instantiate -d NAME="web" -d CPU=1 server_receipe

Couldn't this be accomplished by doing:

1: onetemplate clone $base_template $tmp_template
2: EDITOR=/path/to/script.sh onetemplate update $tmp_template
3: ontemplate instantiate $tmp_template

script.sh will be called just like vim or emacs, or whatever, with $1 the path to the file that needs to be updated. The contents of script.sh are left as an exercise left up to the reader.

Hi Adam,

Yes, in fact we have something similar for our in-house cloud. However, we'd like to expose it via other interfaces and probably add some system-wide checks, like for example a maximum value for a variable.

Other requirement would be to expose it through all the interfaces, so a JAVA client could benefit from it. This requires to put (at least part) of the functionality in the core.

Thanks for your feedback and suggestions!

  • Subject changed from Template Recipes to General user inputs in templates
  • Priority changed from High to Normal

User inputs is now doing this, for Sunstone and CLI. This may be extended. This may not be implemented in the oned daemon.
