Combine two separate lists into a list of dictionaries
https://stackoverflow.com/questions/51898227/ansible-how-to-combine-two-separate-lists-into-a-list-of-dictionaries Suppose we have
"ansible_interfaces": [
"ens32",
"ens34"
]
host_ipv4_list:
- "192.168.0.1"
- "192.168.1.1"
We want
host_network_info:
- { "interface": "ens32", "ip": "192.168.0.1" }
- { "interface": "ens34", "ip": "192.168.1.1" }
Solution:
set_fact:
host_network_info: "{{ host_network_info | default([]) + [dict(interface=item[0], ip=item[1])] }}"
loop: "{{ ansible_interfaces | zip(host_ipv4_list) | list }}"
