Ansible - Templates

Template Module Attributes

The following additional options can be used to modify the template module's default operations:

• Force: If the target file already exists, the parameter Force will determine whether or not it needs to be replaced. Yes is the default value.
• Group: The group's name that should control the directory. The process is comparable to running the chown command on a file on a Linux machine.
• Backup: You should specify the value of the backup option to yes if you want a backup file to be produced in the destination directory. No is the value by default. And each time the target directory changes, a backup file will be generated.
• Mode: This parameter is used to set the permissions for the target file specifically.

Example

Consider the below example.

The below code block shows the code of Playbook.yml.

---  
- hosts: all  
  vars:  
    v1: 'Sentence1'  
    v2: 'Sentence2'  
  tasks:  
    - name: Basic Template Example  
      template:  
        src: example1.j2  
        dest: /home/Apurv/Documents/output.txt  

{{v1}}  
No change in this line  
{{v2}}  

Output:

Sentence1
No change in this line  
Sentence2
