Hello!
I'm deploying a cluster of app-servers behind a load balancer. When an
appserver has been installed - and has passed some basic tests - I would
like to add it to a dynamic group. Later, in the nginx (the load balancer)
config file template, I'm iterating over this dynamic group in order to add
only functioning app-servers to the nginx load balancing configuration.
So, in the playbook, which sets up the app-server, I have this here at the
end:
- name: add new instance to functioning applayer group
local_action:
add_host name={{ inventory_hostname }}
groupname=functioning-applayer-hosts
However, only one of my app servers is added to this group. In fact, when I
watch Ansible process my playbooks, it just looks like this:
...
TASK: [appserver | running unit tests]
****************************************
skipping: [54.206.225.114]
skipping: [54.206.165.147]
TASK: [appserver | add new instance to functioning applayer group]
************
ok: [54.206.165.147] <====== ONLY DONE FOR A SINGLE HOST, FOR SOME
REASON...
TASK: [appserver | stopping django server]
************************************
changed: [54.206.165.147]
changed: [54.206.225.114]
TASK: [appserver | starting django server]
************************************
<job 82131229693> finished on 54.206.165.147
<job 82131229693> finished on 54.206.225.114
...
You can see that my unit tests are run on both app-servers, the Django
process is restarted on both app-servers, but right in the middle only one
of them is added to the "functioning-applayer-hosts" group.
Any idea why this is the case and how I could fix this?
Thank you very much...
Juergen
