How to use escape characters in lineinfile ansible












0















I am writing the ansible play for adding the users.



So far I got this.



- name: Add user to sudoers

  hosts: all_hosts

  su: yes

  su_user: root

  tasks:

    - lineinfile: line='worker_temp ALL=(ALL) NOPASSWD: /bin/sh' dest='/etc/sudoers'


I am able to add the user which is another task.
I am trying to add the same user in the sudoers file.
It fails



ERROR! Syntax Error while loading YAML.

  mapping values are not allowed here



at   - lineinfile: line="worker_temp ALL=(ALL) NOPASSWD: /bin/sh" dest="/etc/sudoers"

                                                       ^ here


I tried by adding escaping quotes, but then it appendsthe folloing line in sudoers file 



worker_temp ALL=(ALL) NOPASSWD':' /bin/sh


this line has '' unwanted around :



How can I get only 



worker_temp ALL=(ALL) NOPASSWD: /bin/sh


Thanks.

    I don't understand why you are opposed to the line='' syntax, but either way, if you switch to the formal YAML map syntax this entire discussion evaporates

You can only escape quotes if you actually quote a scalar, and in your example the value to the key linenfile is not a quoted scalar as this is the value:



line='worker_temp ALL=(ALL) NOPASSWD: /bin/sh' dest='/etc/sudoers'


(although there are quotes in the scalar, a quoted scalar needs to start (and end) with a single or double quote).



Just putting double quotes around that will prevent your parser from mis interpreting the second : on that line as a value indicator as well as first:



- lineinfile: "line='worker_temp ALL=(ALL) NOPASSWD: /bin/sh' dest='/etc/sudoers'"
