How To Determine Your Public IP Address Programmatically From An Ansible Task

Short answer: use ipify

ipify provides a simple public address API.

Using the tool, you can determine your public IP address programmatically. If you are using the shell:

curl 'https://api.ipify.org'

Using it in a shell script:

my_ip=$(curl 'https://api.ipify.org' -s)
echo $my_ip

Using the Ansible ipify module:

- hosts: localhost
  vars:
  tasks:
    - name: Get my public IP
      ipify_facts:
        timeout: 20
      delegate_to: localhost
      register: public_ip
    - name: output
      debug: msg="{{ ipify_public_ip }}"

Sample output of Ansible playbook execution:

ansible-playbook ipify.yml 
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'


PLAY [localhost] **************************************************************************************************************************************************************************************************

TASK [Gathering Facts] ********************************************************************************************************************************************************************************************
ok: [localhost]

TASK [Get my public IP] *******************************************************************************************************************************************************************************************
ok: [localhost -> localhost]

TASK [output] *****************************************************************************************************************************************************************************************************
ok: [localhost] => {
    "msg": "49.206.13.205"
}

PLAY RECAP ********************************************************************************************************************************************************************************************************
localhost                  : ok=3    changed=0    unreachable=0    failed=0

Becoming Productive In Bash Using The Keyboard Shortcuts

Moving around

You can use the arrow keys on keyboard to move around in the command line. Bash also provides convenient keyboard shortcuts to navigate effectively. Try them out and see for yourself.

To become a Bash pro user you have to get yourself familiar with the keyboard shortcuts. Once you do, you’ll find yourself productive.

Shortcut	Description
CTRL+b	move backward one character
CTRL+f	move forward one character
ESC+b	move one word backward
ESC+f	move one word forward
CTRL+a	move to beginning of line
CTRL+e	move to end of line
CTRL+p	move to previous line
CTRL+n	move to next line
ESC+<	move to first line of history list
ESC+>	move to last line of history list

Moving around words using ESC+f and ESC+b are my favourites in this list. Jumping to first and last lines of the history list is also useful.
