How to check whether an item is present in an Ansible array?

In Ansible, you can use the in operator to check whether an item is present in an array. Here's an example:

--- - name: Check if an item is present in an array hosts: localhost vars: my_array: - item1 - item2 - item3 tasks: - name: Check if item2 is in the array debug: msg: "item2 is present in the array" when: "'item2' in my_array" - name: Check if item4 is in the array debug: msg: "item4 is not present in the array" when: "'item4' not in my_array"

In this example:

  • The first task checks if 'item2' is present in the my_array variable using the in operator.
  • The second task checks if 'item4' is not present in the my_array variable using the not in operator.

Adjust the variable names and item values according to your specific use case.

  1. "Ansible check if item is in array"

    # Code: - name: Check if item is in array debug: msg: "Item is in array" when: my_item in my_array

    Description: This Ansible code uses the when condition to check if my_item is present in the my_array. If true, it prints a message indicating that the item is in the array.

  2. "Ansible array contains item condition"

    # Code: - name: Verify item in array debug: msg: "Item is present" when: my_item is defined and my_item in my_array

    Description: This Ansible code checks if my_item is defined and if it exists in the my_array, then it prints a message indicating the item is present.

  3. "Ansible check if array has value"

    # Code: - name: Confirm array contains item debug: msg: "Array has the item" when: my_array | intersect([my_item]) | length > 0

    Description: This Ansible code uses the intersect filter to check if the intersection of my_array and a list containing my_item has a length greater than 0.

  4. "Ansible array membership test"

    # Code: - name: Check array membership debug: msg: "Item is a member" when: my_item in my_array

    Description: This Ansible code checks if my_item is a member of my_array using the in operator and prints a message accordingly.

  5. "Ansible check if value exists in list"

    # Code: - name: Validate item existence debug: msg: "Item exists in array" when: my_item is defined and my_item in my_array

    Description: This Ansible code verifies that my_item is defined and exists in the my_array before printing a message confirming its presence.

  6. "Ansible array contains element"

    # Code: - name: Confirm element in array debug: msg: "Element is in array" when: my_item in my_array

    Description: This Ansible code checks if my_item is an element in the my_array and prints a message accordingly.

  7. "Ansible check if item in list"

    # Code: - name: Check item in list debug: msg: "Item is in the list" when: my_item in my_array

    Description: This Ansible code uses the in operator to check if my_item is in the my_array and prints a message accordingly.

  8. "Ansible array item presence validation"

    # Code: - name: Validate item presence debug: msg: "Item is present in array" when: my_item is defined and my_item in my_array

    Description: This Ansible code validates the presence of my_item in my_array and prints a message if it exists.

  9. "Ansible check if value is in array"

    # Code: - name: Verify value in array debug: msg: "Value is in array" when: my_value in my_array

    Description: This Ansible code checks if my_value is present in the my_array and prints a message accordingly.

  10. "Ansible array item existence"

    # Code: - name: Confirm item existence debug: msg: "Item exists in array" when: my_item is defined and my_item in my_array
