The main point of this I am having difficulty in using ternary in
conjunction with a variable and would like to see if this is even possible?
The ternary doesn't seem to like the use of variable substitution inside
its statements - at least how I'm using them.
This is the list I'm trying to create
ports_list: "{{ ports_list|default([]) + [{'port-name': inventory_hostname
+ (place_index > 1) | ternary('1.{{place_index}}','_mgmt')}] }}"
Ultimately in plain English, what I am trying to do is reference the
existing port_order list and...
- For the first port, have it named {{inventory_hostname}}_mgmt
- For all remain ports, have the ports named
{{inventory+hostname}}_1.{{place-index}} onto the end of it so I would end
up with {{inventory_hostname}}_1.1, etc...
The task is...
- name: Populate Port Lists With management and other ports
set_fact:
ports_list: "{{ ports_list|default([]) + [{'port-name':
inventory_hostname + (place_index > 1) |
ternary('1.{{place_index}}','_mgmt')}] }}"
loop: "{{ port_order }}"
loop_control:
index_var: place_index
This works fine for the first entry of the listand I end up with...
device-name_mgmt
For the remaining ports however, I end up with the literal string....
device-name_{{place_index}} - what I am expecting is device-name_1.1
Clearly my knowledge of Jinja is lacking but I can't sort this out
I am working with OpenStack, and this is the list of dictionaries for the
network ports that need to be attached to a server instance
i.e.
"port_order": [
{
"int_type": "normal",
"subnet": "vlan3555.v6",
"type": "mgmt"
},
{
"int_type": "normal",
"subnet": "vlan704.v4",
"type": "provider"
},
{
"int_type": "normal",
"subnet": "vlan3444.v6",
"type": "tenant"
}
This list of dictionaries is built as the main reference for all of the
Ansible tasks so its fairly important this structure doesn't change, but if
there's no way around it I'll update it
