Create Files on App Servers using Ansible

The Nautilus DevOps team is testing various Ansible modules on servers in Stratos DC. They’re currently focusing on file creation on remote hosts using Ansible. Here are the details:

a. Create an inventory file ~/playbook/inventory on jump host and include all app servers.

b. Create a playbook ~/playbook/playbook.yml to create a blank file /tmp/nfsshare.txt on all app servers.

c. Set the permissions of the /tmp/nfsshare.txt file to 0644.

d. Ensure the user/group owner of the /tmp/nfsshare.txt file is tony on app server 1, steve on app server 2 and banner on app server 3.

Note: Validation will execute the playbook using the command ansible-playbook -i inventory playbook.yml, so ensure the playbook functions correctly without any additional arguments.

Steps

Move into playbook directory
```
 cd playbook
```

Create an inventory file with these contents:

     [app]
 stapp01 ansible_user=tony ansible_ssh_password=Ir0nM@n
 stapp02 ansible_user=steve ansible_ssh_password=Am3ric@
 stapp03 ansible_user=banner ansible_ssh_password=BigGr33n

 [all:vars]
 ansible_ssh_common_args='-o StrictHostKeyChecking=no'

Create the playbook.yml and copy-paste the contents from this Playbook YAML file

Run the ansible command:

 ansible-playbook -i inventory playbook.yml

Verify Results: To verify the results we can login into each app server and check tmp directory.
```
 ls -la /tmp
```

Good to Know?

File Creation with Ansible

file Module: Create files, directories, symlinks
State Parameter: touch creates empty files
Ownership: Set user and group ownership
Permissions: Set file mode (octal notation)

File Attributes

Owner: User who owns the file
Group: Group that owns the file
Mode: File permissions (read, write, execute)
State: File type (file, directory, link, absent)

Permission Management

Octal Notation: 0644 = rw-r–r–
Symbolic Notation: u=rw,g=r,o=r
Special Permissions: Sticky bit, setuid, setgid
Default Permissions: umask affects default permissions

Cross-Platform Considerations

User Mapping: Different users on different systems
Group Mapping: Group names may vary
Permission Models: Windows vs Unix permissions
Path Separators: Forward vs backward slashes
