need help in checking if a variable string is in an item string

[Jerome Yanga]

Here is what I have.

vars/main.yml

host_entries:

 - { srv_loc:  'ca', ip_addr:  '10.1.1.1', host_aliases:  'ca-srv-01.example.com ca-srv-01' }

 - { srv_loc:  'ny', ip_addr:  '10.2.1.1', host_aliases:  'ny-srv-01.example.com ny-srv-01' }

 - { srv_loc:  'co', ip_addr:  '10.3.1.1', host_aliases:  'co-srv-01.example.com co-srv-01' }

tasks/main.yml

---

 - name: checking location of server

   raw:  'echo "{{ ansible_hostname }}" | cut -f1 -d"-"'

   register: actual_loc

 - name: adding entries in the hosts file

   lineinfile:

      backup:  yes

      create:  yes

      dest:  /etc/hosts

      group:  root

      line:  "{{item.ip_addr}}     {{item.host_aliases}}"

      mode:  0644

      owner:  root

      state:  present

   when:  ( actual_loc.stdout_lines == item.srv_loc )

   with_items:  "{{ hosts_entries }}"

I am trying to add the correct hosts entries based on the substring of a hostname.  All items are being skipped at the moment due to '"skip_reason": "Conditional check failed", "skipped": true'.  

Please help.  :)

Regards,

j

I apologize for not providing the info below.

version:  2.0.2.0

event:

skipping: [ca-server1] => (item={u'host_aliases': u'ca-srv-01.example.com ca-srv-01', u'ip_addr': u'10.1.1.1', u'srv_loc': u'ca'})  => {"changed": false, "item": {"host_aliases": "ca-srv-01.example.com ca-srv-01", "ip_addr": "10.1.1.1", "srv_loc": "ca"}, "skip_reason": "Conditional check failed", "skipped": true}

Here you have host_entries

But here you have hosts_entries, so one of them is a typo.

You could lose the raw by doing so in the when
when: ansible_hostname.split('-')[0] == item.srv_loc

Thanks, Kai.

You hit the nail on the head.  If there is a doc on how to do this string manipulation, please share with me the URL.

I have just picked it up, but I guess it's a Python string method
https://docs.python.org/2.7/library/stdtypes.html?highlight=split#str.split

Maybe all the Python string methods work, hopefully someone else can
shed some light on that.
