Problem referencing variables

[Dave Florek]

Hi,

I'm trying to see where I'm going wrong here:

Relevant code snippet:

- lineinfile:
        path: /home/"{{ new_user }}"/.ssh/

Error message I get at execution:

ERROR! Syntax Error while loading YAML.


The error appears to have been in '/opt/ansible/setup_scripts/create_user.yml': line 20, column 1, but may
be elsewhere in the file depending on the exact syntax problem.


The offending line appears to be:


  - lineinfile:
        path: /home/"{{ new_user_acct_name }}"/.ssh/authorized_keys
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes.  Always quote template expression brackets when they
start a value. For instance:


    with_items:
      - {{ foo }}


Should be written as:


    with_items:
      - "{{ foo }}"

Can someone point me in the right direction? 

Thanks,

[Branko Majic]

It can easily happen to be an issue elsewhere in the file, but it's
hard to tell since you posted only a very small snippet.

If you comment-out that particular task do you still have the same
issue being reported?

I would double-check the indentation as well, since what you posted as
sample had a bit "deeper" indentation (maybe tabs vs spaces or too much
indentation).

What version of Ansible are you using?

Any reason you wouldn't be using authorized_key module
(http://docs.ansible.com/ansible/latest/authorized_key_module.html)?

Hi Branko,

Thanks for the response. I only posted what was on line 20. I'm noticing a general issue where if I double-bracket variables, even as Ansible instructs me, I still receive error messages. I'm using Ansible version 2.1.1.0. 

Code:

---

- hosts: all

  become: yes

  vars_prompt:

   - name: "new_user"

   - prompt: "What is the name of the new user to create?"

  tasks:

  - name: Create new user

    command: useradd {{ new_user }}

  - name: Generate new SSH pub/priv key for user

# Do you just have a file with a pasted public key for distribution or auto-generate one?

  - name: Add user to local authorized_keys file

  - lineinfile:

        path: /home/"{{ new_user }}"/.ssh/authorized_keys

        state: present

        create: True

#       line: #Reference to what upper decision was

        group: {{ new_user }}

        owner: {{ new_user }}

For some reason, when I reference the new user name as part of a path to set a file, I get the requirement that the variable needs to be in quotes. Any ideas?

It's recommended to show everything, you'll get help a lot faster that
way because the problem can be anywhere as you can see by my comments
bellow.

You need to remove the dash in front of prompt, one list item contains
name and prompt.

You can't have a name: without a module, Ansible will fail.

You need to remove the dash in front of lineinfile.

Remove the double quotes.

When you have {{ after a colon you need to wrap them in single or double
quotes like this "{{ new_user }}".

I don't understand the problem, but maybe the comments about give you
the answer if not show the code and the error message.
