Ansible - Command vs Shell

 If you need a shell environment, use the shell module. 

Command:

ansible <host in inventory> -m ansible.builtin.shell -a '<shell command>'

Example

-ansible webservers -m ansible.builtin.shell -a 'mkdir MyTestFolder'

How to use the Ansible Vault ?

 If your are using a clear password in your YAML file, you can encrypt the file via Ansible-vault.

• How to encrypt the credentials ?

#ansible-vault encrypt MyCredentials.yml

New Vault password: <Enter the password and stored in a safe place>
Confirm New Vault password: <Enter the same password>
 Encryption successful

• How to view the encrypted credentials ?

#ansible-vault view MyCredentials.yml

Vault password: <Enter the password previously chosen>

• How to change data in your file (for example your credentials) ?

decrypt the file MyCredentials.yml

User@Ansible-Host:~/> ansible-vault decrypt MyCredentials.yml
Vault password: <known_key>
Decryption successful

Edit the file with your preferred editor (vim/nano) by changing the data.

Then encrypt the file again

User@Ansible-Host:~/> ansible-vault encrypt MyCredentials.yml
New Vault password: <known_key>
Confirm New Vault password: <known_key>
Encryption successful
