Is it possible to apply a list of items to multiple tasks in an Ansible playbook? To give an example:
- name: download and execute hosts: server1 tasks: - get_url: url="some-url/{{item}}" dest="/tmp/{{item}}" with_items: - "file1.sh" - "file2.sh" - shell: /tmp/{{item}} >> somelog.txt with_items: - "file1.sh" - "file2.sh"
Is there some syntax to avoid the repetition of the item-list?
If you need to execute a task with Ansible more than once, write a playbook and put it under source control. Then you can use the playbook to push out new configuration or confirm the configuration of remote systems.
Ansible with_items plugin is a widely used plugin. You will use it whenever you need loop arrangement in your playbook, because this is the standard lookup used mostly. When we pass a list of items to a task, then task will be performed for all items in that list.
To use the with_items plugins, use the with_items keyword in a playbook and pass a list of items under it. You can then call each item within the specified list and perform the required operations.
As of today you can use with_items
with include
, so you'd need to split your playbook into two files:
- name: download and execute hosts: server1 tasks: - include: subtasks.yml file={{item}} with_items: - "file1.sh" - "file2.sh"
and subtasks.yml
:
- get_url: url="some-url/{{file}}" dest="/tmp/{{file}}" - shell: /tmp/{{file}} >> somelog.txt
There was a request to make with_items
applicable to block
, but the Ansible team has said it will never be supported.
You have the possibility to define a yaml list in a variables file:
--- myfiles: - "file1.sh" - "file2.sh" ...
and then you can use
with_items: "{{ myfiles }}"
in the task.
