Problem with variables structure (loop with_items)

Archives Ansible Project

Hi, I am trying to create a role for multiple installations of apache on one host.

My group_vars:
apache:

  • { name: vhost1,
    dir: installation1,
    …lot of other variables…
    file:

  • { src: /deploy/1.txt, dst: /tmp/1.txt }

  • { src: /deploy/2.txt, dst: /tmp/2.txt }
    }

  • { name: vhost2,
    dir: installation2,
    …lot of other variables…
    file:

  • { src: /deploy/3.txt, dst: /tmp/3.txt }
    }

Task with problem:

  • name: copy files
    copy: src={{ item.file.src }} dest={{ item.file.dst }}
    with_items: apache

Error:
ERROR: Syntax Error while loading YAML script, /roles/apache/vars/main.yml
Note: The error may actually appear before this position: line 39, column 9

file:

  • { src: /deploy/1.txt, dst: /tmp/1.txt }

I try:
My group_vars:
apache:

  • name: vhost1
    dir: installation1
    …lot of other variables…
    file:

  • { src: /deploy/1.txt, dst: /tmp/1.txt }

  • { src: /deploy/2.txt, dst: /tmp/2.txt }

  • name: vhost2
    dir: installation2
    …lot of other variables…
    file:

  • { src: /deploy/3.txt, dst: /tmp/3.txt }

Task with problem:

  • name: copy files
    copy: src={{ item.file.src }} dest={{ item.file.dst }}
    with_items: apache

Error:
fatal: [test] => One or more undefined variables: ‘list object’ has no attribute ‘src’

and also try:
My group_vars
apache:

  • name: vhost1
    dir: installation1
    …lot of other variables…
    file:

  • src: /deploy/1.txt
    dst: /tmp/1.txt

  • src: /deploy/2.txt
    dst: /tmp/2.txt

  • name: vhost2
    dir: installation2
    …lot of other variables…
    file:

  • src: /deploy/3.txt
    dst: /tmp/3.txt

Task with problem:

  • name: copy files
    copy: src={{ item.file.src }} dest={{ item.file.dst }}
    with_items: apache

Error:
fatal: [test] => One or more undefined variables: ‘list object’ has no attribute ‘src’

How can I solve my problem? Depending on my needs, I need to have in the variable “file” specification of one or more files to be copied.

Check with_subelements loop. This is solution to your problem.
