variable trouble - item: not returning correct value

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

  • 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

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

Thanks Matt! That did it!
