Ansible Jinja Template

It puts the files onto a remote system using jinja2 templating language.

Ansible template Module

Example: Template a single file

Step 1: Create a file called my_app.conf.j2 and add below content

env = {{ env }}

local_id = {{ ansible_host }}

local_OSFamily = {{ ansible_facts[‘os_family’] }}

local_OS = {{ ansible_distribution }}

Step 2: Create a ansible play book lets call it template.yaml

—

– name: Parsing Jinja2 templates

hosts: “*”

vars:

env: staging

tasks:

– name: template file onto remote hosts

template:

src: my_app.conf.j2

dest: /tmp/myconfigfile

Step 3: Execute the template playbook and then check on each host machine there will be a /tmp/myconfigfile and the parsed value jinja2 file.

ansible-playbook template.yaml

Example Set Permission for parsed jinja file

—

– name: Parsing Jinja2 templates

hosts: “*”

vars:

env: staging

tasks:

– name: template file onto remote hosts

template:

src: my_app.conf.j2

dest: /tmp/myconfigfile

– name: change the permission for the parsed jinja file

file:

path: /tmp/myconfigfile

owner: raman

mode: ‘0600’

Example Template Multiple files.

Create one more .j2 file let’s say my_host.conf.j2

and write following content

OS = {{ ansible_distribution }}

Create a template.yaml file

—

– name: Parsing Jinja2 templates

hosts: “*”

vars:

env: staging

tasks:

– name: template file onto remote hosts

template:

src: ‘{{ item.src }}’

dest: ‘{{ item.dest }}’

with_items:

– { src: my_app.conf.j2, dest: /tmp/myconfigfile }

– { src: my_host.conf.j2, dest: /tmp/myhostconfigfile}

– name: change the permission for the parsed jinja file

file:

path: /tmp/myconfigfile

owner: raman

mode: ‘0600’

Example user loop

Create a jinja file let’s call it users.j2

[user]

name = {{ user.name }}

username = {{ user.username }}

email = {{ user.username }}@example.com

Create a playbook that stores the parsed value of the jinja template on remote host machines.

—

– name: play for template

hosts: “*”

vars:

users:

– name: John Smith

username: jsmith

– name: Mohit Singh

username: msingh

tasks:

– name: users

user:

name: “{{ user.username }}”

comment: “{{user.name }}”

state: present

loop: “{{ users }}”

loop_control:

loop_var: user

– name: processing jinja template

template:

src: users.j2

dest: “/home/{{ user.username }}/gitconfig”

loop: “{{ users }}”

loop_control:

loop_var: user
