linux - Register Variables in Loop in an Ansible Playbook -
i have 2 ansible tasks follows
tasks: - shell: ifconfig -a | sed 's/[ \t].*//;/^\(lo\|\)$/d' register: var1 - debug: var=var1 - shell: ethtool -i {{ item }} | grep bus-info | cut -b 16-22 with_items: var1.stdout_lines register: var2 - debug: var=var2 which used list of interfaces in machine (linux) , bus address each. have 1 more task follows in tha same playbook
- name: binding interfaces shell: echo {{ item.item }} with_flattened: var2.results register: var3 which expect iterate on value var2 , print bus numbers.
var2.results follows

- name: binding interfaces shell: echo {{ item.item.stdout}} with_flattened: var2.results # with_indexed_items: var2.results register: var3 but not giving bus values in stdout correctly. appreciate in listing variable of variable value in task given below when second variable , indexed list. trying avoid direct index numbering such item[0] because number of interfaces dynamic , direct indexing may result in unexpected outcomes.
thanks
is you're looking for:
