I have 10 hosts and 10 files. I want to copy one of 10 files to corresponding host:
1_file.txt -> 1_host
2_file.txt -> 2_host
...
10_file.txt -> 10_host
I've tried to do it with zip filter, like
- name: Copy splitted files to instances
copy:
src: "{{ item.0 }}"
dest: "{{ remote_ips_file }}"
delegate_to: "{{ item.1 }}"
loop: "{{ splitted_files.files | zip(instances) | list }}"
but got an error:
{"msg": "Unexpected failure during module execution.", "stdout": ""}
Another way (from ChatGPT) was:
- name: Copy files to hosts
hosts: "{{ hosts }}"
tasks:
- name: Copy file to host
copy:
src: "{{ item.0 }}"
dest: "/tmp/{{ item.1 }}"
loop: "{{ zip(files, hosts) }}"
vars:
files: ['/path/to/file1', '/path/to/file2']
hosts: ['host1', 'host2']
But also got an error:
zip is undefined
How to do it with proper way?
Edit
I've found workaround, but it works not in parallel:
- name: Copy splitted files to instances
copy:
src: "{{ item.0.path }}"
dest: "{{ remote_ips_file }}"
delegate_to: "{{ item.1 }}"
with_together:
- "{{ splitted_files.files }}"
- "{{groups['all']}}"

Given the lists
my_files: [file1, file2]
my_hosts: [host1, host2]
Create the dictionary
hosts_files: "{{ dict(my_hosts|zip(my_files)) }}"
gives
hosts_files:
host1: file1
host2: file2
Use the dictionary in the task
- copy:
src: "{{ hosts_files[inventory_hostname] }}"
dest: /tmp
