I saw this in the ansible-examples / openshift / openshift_ec2 / roles /
mongodb / tasks / main.yml
- name: Initialize the replication set
shell: /usr/bin/mongo --port "{{ mongod_port }}"
/tmp/repset_init.js;touch /opt/rep.init creates=/opt/rep.init
when: inventory_hostname == groups['mongo_servers'][0]
What does the [0] mean in when: inventory_hostname ==
groups['mongo_servers'][0] ?
I wanted to find a conditional that would say: when inventory_hostname is
not in group mailservers
It seems to work for me with this now:
when: inventory_hostname != groups['mailservers'][0]
But I just don't understand what the syntax means.
Thanks!
