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"
|
|
node3:
|
|
dmiString: 'system-uuid'
|
|
id: 'A8C85861-1B16-4803-8689-AFC62984F8F6'
|
|
nic1: em3
|
|
# Dell PowerEdge
|
|
nodegroup1:
|
|
dmiString: "system-product-name"
|
|
id: "PowerEdge R630"
|
|
nic1: em3
|
|
nic2: em1
|
|
nic3: em2
|
|
# Cisco UCS B200-M4"
|
|
nodegroup2:
|
|
dmiString: "system-product-name"
|
|
id: "UCSB-B200-M4"
|
|
nic1: enp7s0
|
|
nic2: enp6s0
|
|
|
|
This will result in the first node* entry where either:
|
|
a) a mac matches a local device
|
|
or b) a DMI String matches the specified id
|
|
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)
