[ansible-project] retrieving endpoint from data in the elasticache module

[DenMat Gone]

Hi all,

I have a question regarding the data returned from the elasticache module.

I am able to create a memcached elasticache endpoint but I would like to
retrieve that endpoint for use later in the playbook.

I register the result and can use debug to show that all the data I need is
returned.

So something like the following:
- name: create utilities elasticcache
elasticache:
name: "utilities-elc"
...
< snip >
...
register: utilities_elc

- debug: var=utilities_elc.elasticache.data
register: utilities_elc_data

- debug: var=utilities_elc_data

That returns what I expect:
TASK: [vpc | debug var=utilities_elc_data]
************************************
ok: [localhost] => {
"var": {
"utilities_elc_data": {
"invocation": {
"module_args": "var=utilities_elc.elasticache.data",
"module_name": "debug"
},
"var": {
"utilities_elc.elasticache.data": {
"AutoMinorVersionUpgrade": true,
"CacheClusterCreateTime": 1430609910.496,
"CacheClusterId": "utilities-elc",
"CacheClusterStatus": "available",
"CacheNodeType": "cache.m3.medium",
"CacheNodes": [
{
"CacheNodeCreateTime": 1430609910.496,
"CacheNodeId": "0001",
"CacheNodeStatus": "available",
"Endpoint": {
"Address":
"utilities-elc.i4w6la.0001.apse2.cache.amazonaws.com",
"Port": 11211
},
"ParameterGroupStatus": "in-sync",
"SourceCacheNodeId": null
}
],
.....
}

So my solution I tried to get the endpoint is:
utilities_elc.elasticache.data.cachenodes[0].endpoint.address


But that returns:
"One or more undefined variables: 'dict object' has no attribute
'cachenodes'"

I would have thought that worked? What aren't I getting?

If I use a with_dict: on the variable I can list the cachenodes key so it
is baffling me.

Case matters when accessing keys.

Instead of cachenodes it should likely be CacheNodes.
