Ansible, error in getting results for multiple register command

Question

I tried to get results as follow:

- name: Populate known_hosts
  hosts: spectrum_scale
  gather_facts: no
  tags: set_known_hosts
  become: true
  tasks:
  - name: Get hosts list from known_host
    ansible.builtin.shell:
      cmd: "cat /root/.ssh/known_hosts |
              grep {{ hostvars[item].ansible_fqdn }}"
    with_items: "{{groups['spectrum_scale']}}"
    ignore_errors: yes
    register: hosts2add

  - name: Scan for SSH client keys
    ansible.builtin.shell:
      cmd: "ssh-keyscan {{ hostvars[h2a_r.item].ansible_fqdn }},
                        {{ hostvars[h2a_r.item].ansible_default_ipv4.address }}
                        2>/dev/null"
    loop: "{{ hosts2add.results }}"
    loop_control:
      loop_var: h2a_r
    when: h2a_r.rc
    register: ssh_scan


  - name: Display debug
    ansible.builtin.debug:
      msg: "FINGERPRINT TO ADD {{ ss_r.stdout_lines }}"
      # var: ss_r.stdout_lines   
    loop: "{{ ssh_scan.results }}"
    loop_control:
       loop_var: ss_r

I got the error:

{"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'stdout_lines'

What's really weird is that if use the var instead of msg I got the value I need

var: ss_r.stdout_lines

I found an old post (Ansible register result of multiple commands) but that solutions suggested seem not work for me

Thank you for helping

Answer 1

I'm not sure what you're looking for, but result is a dictionary who contains all the values you stored.

if you're going to use loop for loops you need to pass dict2items

E.G.:

  - name: Display debug
    ansible.builtin.debug:
      msg: "FINGERPRINT TO ADD {{ ss_r.stdout_lines }}"
      # var: ss_r.stdout_lines   
    loop: "{{ ssh_scan.results | dict2items }}"
    loop_control:
       loop_var: ss_r

Probably that resolve the error message you stated before.

You might convert all styling to element attributes using SVGOMG:

1. replace your embedded <image> element by the decoded data url content. Your parent svg should look something like this:

    <!-- parent svg -->
    <svg xmlns="http://www.w3.org/2000/svg" >
        <!-- embedded svg decoded data url -->
        <svg xmlns="http://www.w3.org/2000/svg" height="50000" width="50000">
        <style>
            .gliffy-rte-text {
             }
        </style>
        </svg>
    </svg>
   

2. Use SVGOMG "inline styles" and "style to attribute"parameter:

You should disable all other optimizing parameter, since they might strip to many other attributes.

Expected before result

    <svg viewBox="0 0 256 256" xmlns="http://www.w3.org/2000/svg">
        <style>
        circle{
            fill:none;
            stroke: orange;
            stroke-width:10;
          }
        </style>
        <circle cx="128" cy="128" r="100"/>
    </svg>
      

After

    <svg viewBox="0 0 256 256" xmlns="http://www.w3.org/2000/svg">
        <circle cx="128" cy="128" r="100" fill="none" stroke="orange" stroke-width="10"/>   
    </svg>

Open the wrapper file in a browser. Right-click on the area containing the embedded SVG, and choose "Save (image) as...". If the wrapper contains multiple <image> tags, you will have to save them to separate files, but at least they will be in a form Inkscape can handle.

If you want to get them all together in one SVG file again, you will have to re-import them via the Inkscape import function. Take care to select 'Include as editable object', or you will end up right where you started:

The speculations above about CSS are unsubstantiated, btw. Inkscape will convert the content of a <style> element into inline style attributes, but otherwise handle them correctly. What happened is stated quite clearly in the above screenshot: data URLs embeded via an <image> tag will not be editable in Inkscape.
