how to get the controller ip address

Archives Ansible Project

hello all

i am trying to get the controller ip address that is used to run the playbook.
The ip is the one when the ssh connection establishes to remote.

debug: msg=“{{ (ansible_env|default({})).SSH_CLIENT|default(‘’)}}”

the SSH_CLIENT in my case is always empty. yes, i have gather facts and still empty.

i have to workaround this by

  • name: Get the IP of the controller
    shell: “ss -4 -ntp 2> /dev/null | head -2 | grep sshd | awk ‘{print $4}’ | awk -F: ‘{print $1}’”
    ignore_errors: yes
    no_log: yes
    register: ssh_ip

but this is not reliable because there can be other users connected and the above only gets the first item

any help is appreciated, thanks in advance

  debug: msg="{{ (ansible_env|default({})).SSH_CLIENT|default('')}}"

Thats because SSH_CLIENT is not a fact so your default filter is kicking in.

i have to workaround this by

   - name: Get the IP of the controller
     shell: "ss -4 -ntp 2> /dev/null | head -2 | grep sshd | awk '{print
$4}' | awk -F: '{print $1}'"
     ignore_errors: yes
     no_log: yes
     register: ssh_ip

You could use delegated_facts

Thanks Kai

i solved my problem this way

  • name: get ansible env
    setup: filter=ansible_env
    register: a_env
    delegate_to: “{{ target_hosts }}”
    become: false
    delegate_facts: true

thanks for pointing the delegate part.

have a nice week.
my regards
