variable trouble - item: not returning correct value

[David Neudorfer]

I need to reference the variable hostvars['{{ item }}'].rax_accessipv4 in a task but I'm getting the node name and not the IP address.

In the task rackspace_clb | Add servers to Load balancer I need address: to be the IP address displayed in rackspace_clb | debug hostvars.

Thank you.

- name: debug hostvars {{ groups.web5 }}

  debug:

    var: hostvars['{{ item }}'].rax_accessipv4

  with_items: groups.web5

    load_balancer_id: "{{ lb.balancer.id }}"

    address: hostvars['{{ item }}'].rax_accessipv4

    port: 80

I think you just need to adjust some jinja syntax:

- name: debug hostvars {{ groups.web5 }}

  debug:

    var: hostvars[item].rax_accessipv4

  with_items: groups.web5

- name: Add servers to Load balancer

  rax_clb_nodes:

    load_balancer_id: "{{ lb.balancer.id }}"

    address: "{{ hostvars[item].rax_accessipv4 }}"

    port: 80

    condition: enabled

    type: primary

    wait: yes

    region: ORD

  with_items: groups.web5
