Can anyone help with this basic question? I have a dictionary variable and I'd like to print it.
dict_var:
- key1: "val1"
- key2: "val2"
- key3: "val3"
Is it possible to loop and print its content in a playbook?

Q: "Loop and print variable's content."
A: The variable dict_var is a list. Loop the list, for example
- hosts: localhost
vars:
dict_var:
- key1: "val1"
- key2: "val2"
- key3: "val3"
tasks:
- debug:
var: item
loop: "{{ dict_var }}"
gives (abridged)
"item": {
"key1": "val1"
}
"item": {
"key2": "val2"
}
"item": {
"key3": "val3"
}
Q: "Loop and print dictionary."
A: There are more options when the variable is a dictionary. For example, use dict2items to "loop and have key pair values in variables" item.key and item.value
- hosts: localhost
vars:
dict_var:
key1: "val1"
key2: "val2"
key3: "val3"
tasks:
- debug:
var: item
loop: "{{ dict_var|dict2items }}"
gives (abridged)
"item": {
"key": "key1",
"value": "val1"
}
"item": {
"key": "key2",
"value": "val2"
}
"item": {
"key": "key3",
"value": "val3"
}
The next option is to loop the list of the dictionary's keys. For example
- debug:
msg: "{{ item }} {{ dict_var[item] }}"
loop: "{{ dict_var.keys()|list }}"
gives (abridged)
"msg": "key1 val1"
"msg": "key2 val2"
"msg": "key3 val3"

If all you want to do is printing the dictionary items, you can do:
- debug: msg="{{ item }}"
with_items: "{{ dict_var | dict2items }}"

THank you for your message :) Basically, print is the first step. Later, I would like to use them and for example build another variable using the values. Would it be possible to loop and have key pair values in a variable ?

Besides, I get a message when trying your solution: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'item' is undefined\n\n
