How to create a task dict from a templated variable

[Gianni Stubbe]

Hello,

I have a variable file that defines the config state of my network hardware. As I would need to create lots of if and loops in loops I would like to be able to template the modules so that the amount of sessions I open to the device stays low.

I currently have this but this does not work as I get the error:
FAILED! => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "msg": "Failure when processing no_log parameters. Module invocation will be hidden. dictionary requested, could not parse JSON or key=value"}

- name: L2 - Config Arista
  block:
    - set_fact:
        physical_interface_config: |
          {% for L2_phys in L2.physical %}
          - name: {{ L2_phys.name }}
          {%  if L2_phys.description is defined and L2_phys.description != "" %}
            description: "{{ L2_phys.description }}"
          {%  endif %}
          {% if L2_phys.mtu is defined %}
            mtu: {{ L2_phys.mtu }}
          {% endif %}
          {% if L2_phys.autoneg is defined and L2_phys.autoneg %}
            duplex: auto
          {% endif %}
          {% if L2_phys.link_speed is defined %}
            speed: {{ L2_phys.link_speed }}
          {% endif %}
          {%  if L2_phys.vid is not defined %}
            mode: layer3
          {%  else %}
            mode: layer2
          {%  endif %}
          {% endfor %}
        L2_config: |
          {% for L2_phys in L2.physical %}
          - name: {{ L2_phys.name }}
          {%-  if L2_phys.vid is defined %}
          {%-    if L2_phys.vid.untagged is defined %}
            untagged:
              vlan: {{ L2_phys.vid.untagged }}
          {%-    endif %}
          {%-    if L2_phys.vid.tagged is defined %}
            trunk:
              vlan: {{ L2_phys.vid.tagged }}
          {%-      if L2_phys.vid.pvid is defined %}
              native_vlan: {{ L2_phys.vid.pvid }}
          {%-      endif %}
          {%-    endif %}
          {%-  endif %}
          {%- endfor %}


    - name: L2 - Configure physical interfaces

The module expects a list in the config parameter, but you are passing a string with contains (hopefully valid) YAML.

Using

config: "{{ physical_interface_config | from_yaml }}"

might bring you closer to the solution.
