Hi,
I'm trying to create a batch of json files, that will pull values from an
inventory group.
Ideally, what I would like to have happen is 10 different files are created
(the inventory group has 10 nodes in it), using both the position of the
node in the inventory list and the fqdn of the node as the values that are
populated into these json files.
At this point, what I'm not sure how to do it create 10 separate files (I
can create one big one), which uses the aforementioned values.
My template (this is what generates the one big file:
{% for node in groups['yarn-nms'] %}
{
"instanceId": "{{ loop.index }}",
"name": "yarn-nm",
"cluster": "stg",
"image": "{{ image }}",
"instance": {
"cpu": 24,
"mem": 80000
},
"constraints": [[ "hostname", "CLUSTER", "{{ node }}" ]]
}
{% endfor %}
I tried stuffing that loop into the task that creates the json files:
---
- name: Make directory for json blobs
file:
path: ~/blobs
state: directory
- name: Create json blobs
template:
src: pin-nm.json.j2
dest: ~/blobs/pin-nm{% for node in groups['yarn-nms'] %}{{ loop.index }}{%
endfor %}.json
but instead of giving me 10 different files, it gave me one file named
pin-nm12345678910.json. And not surprisingly, the template didn't inherit
any values.
Can anyone offer any suggestions on how to create the 10 separate files,
with the values passed through to the templates? Or even just how to create
a loop that creates the 10 different files - I'm pretty sure I could figure
it out from there.
Thanks,
AP
