Heat now supports release name aliases, so we can replace the inconsistent mix of date related versions with one consistent version that aligns with the supported version of heat for this t-h-t branch. This should also help new users who sometimes copy/paste old templates and discover intrinsic functions in the t-h-t docs don't work because their template version is too old.

Configure os-net-config mappings for specific nodes
|
|
Your environment file needs to look like:
|
|
parameter_defaults:
|
|
NetConfigDataLookup:
|
|
node1:
|
|
nic1: "00:c8:7c:e6:f0:2e"
|
|
node2:
|
|
nic1: "00:18:7d:99:0c:b6"
|
|
This will result in the first nodeN entry where a mac matches a
|
|
local device being written as a mapping file for os-net-config in
|
|
/etc/os-net-config/mapping.yaml
|
|
|
|
parameters:
|
|
# Note this requires a liberty heat or newer in the undercloud due to
|
|
# the 2015-10-15 (which is required to enable str_replace serializing
|
|
# the json parameter to json, another approch with a string parameter
|
|
# will be required for older heat versions)
|
