ansible with elastic search with Jinja2 Template

[Bishwajit Samanta]

Hi, my question is :: 

--------------------------------

My ansible script will be running for multiple systems. But in elasticsearch.jinja2 how can i change the value of node.name for different systems.

Jinja 2 Code::-

-------------------

# ---------------------------------- Cluster -----------------------------------

#

# Use a descriptive name for your cluster:

#

 cluster.name: {{ my_defined_cluster_name }}

#

# ------------------------------------ Node ------------------------------------

#

# Use a descriptive name for the node:

#

 node.name: {{ my_defined_node_name }}

#

# Add custom attributes to the node:

#

# node.rack: r1

If i am running this jinja2 file, across all the systems the value of node.name will be same. But i dont want this, i want to put some other values when it runs to other systems. 

what modification i can do in Jinja2 file , can anyone help me ??

My ansible playbook looks like this::

---

  template:

    src: elasticsearch.jinja2

    dest: /etc/elasticsearch/elasticsearch.yml

    owner: root

Can anyone help me in my problem please ?

You can use:

node.name: {{ansible_hostname}}

Which will use the hostname defined on the remote host.

Or you can use:

node.name:{{inventory_hostname}}

Which will use the inventory hostname defined in your Ansible inventory.

For reference:

Hope this helps.
