How do you change ansible_default_ipv4?

Question

I\'d like to change ansible_default_ipv4 to point to eth1 instead of eth0. Can I do this in either the playbook or via the --extra-vars option?

Answer 1

ip -4 route get 8.8.8.8 was not working on my server.

I created this work around.

- name: find default ipv4... this is a bit of a hack. shell: ifconfig $(route | grep default | awk '{print $(NF)}') | grep 'inet' | awk '{ print $2}' register: ipv4_address

Now I can use ipv4_address wherever needed!
