I'm sure this must've come up before but I couldn't find an answer.
I have a list of hosts in a group. I want to write an index number on each
of those hosts in a file. E.g. the first host has a file that contains 1,
the second host has a file that contains 2 etc.
Now I know I can access the hosts using the groups variable E.g.
groups["mygroup"] but i can't find any reference to an index so the host
can find out which number it is.
Example play
...
- name: Add instance to new host group
add_host:
name: "{{ item }}"
group: zk
with_items:
- server1
- server2
- server3
- name: deploy to zk group
hosts: zk
tasks:
- name: write a myid file based on the position in the group
copy:
content: {{ some_magic_variable?????? }}
dest: /zookeeper-data/myid
In the above server i would expect to end up with three servers each with a
myid file that contains 0, 1 or 2
Anyone know if that magic variable exists?
