How to run a playbook as normal user in the remote machine

 For this example you need to create the following directories as best practices

For example

root
 |
 ---- group_vars
 |
 -----roles
 |          |
 |          ----common
 |-- site.yml
 |-- hosts

Create the root directory in this example named ansible

#mkdir  ansible

create the group_var and roles directories

#mkdir group_vars
#mkdir roles

Create the files site.yml and hosts

# touch site.yml
# touch hosts

Too create the common directory change to the directory roles and execute the following command

ansible-galaxy init common

this command create the standard infrastructure directories for use with ansible playbook

For this example i would like to put the sudoers files in some machines to get this result we need to go into the common directory and there go into the tasks directory you are going to find a file named main.yml open it and copy the following

remember start the file with 3 --- this indicate the beginning of the YAML file

---

- name: Sudo file
  template: src=sudoers.j2 dest=/etc/sudoers

After this we change to the directory template and create a new file sudoers .j2 that include the following

Defaults    requiretty
Defaults   !visiblepw
Defaults    always_set_home
Defaults    env_reset
Defaults    env_keep =  "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"
Defaults    env_keep += "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE"
Defaults    env_keep += "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT LC_MESSAGES"
Defaults    env_keep += "LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE"
Defaults    env_keep += "LC_TIME LC_ALL LANGUAGE LINGUAS _XKB_CHARSET XAUTHORITY"
Defaults    secure_path = /sbin:/bin:/usr/sbin:/usr/bin
root    ALL=(ALL)       ALL
test     ALL=(ALL)       ALL

Now go back to the root directory in this case ansible and edit site.yml and include the following:


---
- name: apply common configuration to all nodes
  hosts: all
  remote_user: test

  roles:
    - common


remote user = is the user that is going to connect to the machine and already have sudo access in the macchine

After this edit the hosts files for example 
[TEST]    <-- title of the group
10.0.0.1    <--ip or hostname
test.example.com



To run our playbook exeucte the following command

#ansible-playbook -i hosts site.yml -b --become-user=root -kK

This command is going to ask the username password in this case test password user and the sudo password normally the same or can be different


 in case you get the following error

Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host.


Run the following command to get the inventory of the hosts and add the ssh keys locally

#ansible -m ping -i hosts

After all the keys has been saved in the local machine you can re-run the command ansible-playbook and is going to works as normal
