I want to evaluate multiple condition in ansible using when, here is my playbook:
- name: Check that the SSH Key exists
local_action:
module: stat
path: "/home/{{ login_user.stdout }}/{{ ssh_key_location }}"
register: sshkey_result
- name: Generating a new SSH key for the current user it's not exists already
local_action:
module: user
name: "{{ login_user.stdout }}"
generate_ssh_key: yes
ssh_key_bits: 2048
when: sshkey_result.rc == 1 and ( github_username is undefined or github_username |lower == 'none' )
here is my var file for reference:
---
vpc_region: eu-west-1
key_name: my_github_key
ssh_key_location: .ssh/id_rsa.pub
When I try to execute this playbook, I am getting this error:
TASK: [test | Check that the SSH Key exists] **********************************
ok: [localhost -> 127.0.0.1]
TASK: [test | Generating a new SSH key for the current user it's not exists already] ***
fatal: [localhost] => error while evaluating conditional: sshkey_result.rc == 1 and ( github_username is undefined or github_username |lower == 'none' )
FATAL: all hosts have already failed -- aborting
Can somebody point me out that how we can use multiple conditions with ansible on single task.
Thanks
This question is related to

The problem with your conditional is in this part sshkey_result.rc == 1
, because sshkey_result
does not contain rc
attribute and entire conditional fails.
If you want to check if file exists check exists
attribute.
Here you can read more about stat module and how to use it.
Adding to https://stackoverflow.com/users/1638814/nvartolomei answer, which will probably fix your error.
Strictly answering your question, I just want to point out that the when:
statement is probably correct, but would look easier to read in multiline and still fulfill your logic:
when:
- sshkey_result.rc == 1
- github_username is undefined or
github_username |lower == 'none'
https://docs.ansible.com/ansible/latest/user_guide/playbooks_conditionals.html#the-when-statement
You can use like this.
when: condition1 == "condition1" or condition2 == "condition2"
Link to official docs: The When Statement.
Also Please refer to this gist: https://gist.github.com/marcusphi/6791404
Also you can use default()
filter. Or just a shortcut d()
- name: Generating a new SSH key for the current user it's not exists already
local_action:
module: user
name: "{{ login_user.stdout }}"
generate_ssh_key: yes
ssh_key_bits: 2048
when:
- sshkey_result.rc == 1
- github_username | d('none') | lower == 'none'
