The test to the loadbalancer itself never fails, and serves the same
content as the websites (although host and metadata are a bit different),
and I can't for the life of me figure out the disconnect.
If someone can point me in the right direction it would be appreciated.
All hosts are ubuntu 16.04.01 LTS
hostnames:
loadbalancer - Ansible-nginx
webcluster - AnsibleWeb, AnsibleWeb2
All AWS EC2 instances
The loadbalancer lines in my status playbook:
- hosts: loadbalancer
tasks:
- name: verify backend index response
uri: url=http://{{item}} return_content=yes
with_items: '{{groups.webcluster}}'
register: app_index
- fail: msg="index failed to return content"
when: "'Hello, from sunny {{item.item}}!' not in item.content"
with_items: "{{app_index.results}}"
Output of the play before it stops:
