Ansible RDS module only works once? - amazon-web-services

Question

I'm using the RDS module in Ansible two times during a play. First time, it records the CNAME. Second time, it waits until the database status is "available".
Problem I'm running into is that it works as expected the first time, but the second time, it fails.
---
- name: Wait for RDS to be out of creating state and get its CNAME
rds:
command: facts
instance_name: '{{ wp_db_instance}}'
region: "{{ region }}"
register: rds_facts
until: rds_facts.instance.status != "creating"
retries: 15
delay: 30
become: no
- name: Set Endpoint variable
set_fact: rds_db_endpoint="{{ (rds_facts.stdout|from_json).DBInstances[0].Endpoint.Address }}"
The above code works as expected. It waits for the instance to leave "creating" status and records the name.
Later on in the play, it runs the following.
---
- name: Wait for RDS instance to be in available state
rds:
command: facts
instance_name: '{{ wp_db_instance}}'
region: "{{ region }}"
register: rds_facts_available
until: rds_facts_available.instance.status == "available"
retries: 55
delay: 30
become: no
This one fails due to "'dict object' has no attribute 'instance'" which tells me the module did not return any facts. Why wouldn't it though? Is there a problem with calling the module twice?
Any help would be appreciated.

Answer 1

I think I found the answer. It's kind of out there and I'm not sure if this is what fixed it, but here's what I did that works.
The first module (the one that worked) is a part of YAML that's called upon by main.yml.
- name: Get RDS endpoint
include: get_rds_endpoint.yml
delegate_to: localhost
become: no
The second module is a part of a different YAML but the files name is a variable:
- name: Configure DB
include: "{{configureDBFile}}"
delegate_to: localhost
become: no
I changed "{{configureDBFile}}" to the name of the actual file and the issue went away.
I am doing regression testing of our old playbooks against the latest release so I have to wonder if an update at some point changed the way environment variables/credentials are passed down?

Change your second tasks as below
---
- name: Wait for RDS instance to be in available state
rds_instance_info:
db_instance_identifier: '{{ wp_db_instance}}'
region: "{{ region }}"
register: rds_facts_available
until: rds_facts_available.instances[0].db_instance_status == "available"
retries: 55
delay: 30
become: no
