I'm unable to access the value of a variable defined in group_vars/all in a simple `local.yml' playbook.
Directory structure I have:
/group_vars
/all
local.yml
Content of group_vars/all:
key_name: bar
Content of local.yml:
- name: Local example
connection: local
gather_facts: no
tasks:
- debug: msg="Key is {{ key_name }}"
Here's how I run the playbook:
ansible-playbook -i localhost, local.yml
The error message:
PLAY: Local example *************************************************************
TASK [debug msg=Key is {{ key_name }}] ******************************************
fatal: [localhost]: FAILED! => {"msg": "ERROR! the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'key_name' is undefined", "failed": true}

This is a bug on the master branch, which is unstable:

The following ansible-playbook works fine for non-sudo access.
But fails when I un-comment become:yes
---
- hosts: all
become: yes
tasks:
- name: Register the policy file in a variable
read_csv:
path: policy.csv
delegate_to: localhost
register: csv_file
- name: Check rules pre-remediation
command: "{{ item.Compliance_check }}"
register: output
with_items:
"{{ csv_file.list }}"
- name: Perform remediation
command: "{{ item.item.Remediation }}"
when: item.item.Expected_result != item.stdout
with_items:
"{{ output.results }}"
The inventory file looks like:
10.136.59.110 ansible_ssh_user=username ansible_ssh_pass=password ansible_sudo_pass=password
Error I'm facing is:
user#hostname:~/git-repo/MCI$ ansible-playbook playbook.yaml -i inventory

Can't understand why this error is showing. I have tried providing correct sudo passwords in both inventory as well as at run-time using --ask-become-pass
Please help find out the cause of the error.
I created a playbook which clears cache, I'm trying to pass a url to a variable, and when I execute the playbook I get an empty array for that parameter.
In my playbook I have a vars module with this variable (environment), it gets defined when you pass in a variable to the ansible-playbook command
vars:
environment: "{{testenv}}"
-e testenv=https://www.test1.com
When I execute the playbook I get this error.
Do I need to format the url in someway?
fatal: [localhost]: FAILED! => {"changed": false, "msg": "unknown url type: '[]/content/clear_cache?
Your issue is coming from the fact that environment is a reserved variable, as pointed in the second row of this table in the documentation:
Valid variable names
Not valid
foo
*foo, Python keywords such as async and lambda
foo_env
playbook keywords such as environment
foo_port
foo-port, foo port, foo.port
foo5, _foo
5foo, 12
Source: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#creating-valid-variable-names
So, you just need to change your variable name to something else and it will work.
Given the playbook:
- hosts: all
gather_facts: no
tasks:
- debug:
msg: "{{ _environment }}"
vars:
_environment: "{{ testenv }}"
When run:
$ ansible-playbook play.yml -e testenv=https://www.test1.com

Below is how my complete helpA.yml playbook looks like:
- hosts: localhost
tasks:
- name: "Construct File Path {{ inventory_hostname }} before Deployment."
tags: validate
include_vars:
file: "{{ item }}"
with_fileglob:
- "vars/{{ Layer }}_*.yaml"
- name: "set_fact"
tags: validate
set_fact:
fpath_APP: "{{ fpath_APP + [ BASEPATH ~ '/' ~ vars[item.split('.')[1]] ~ '/' ~ item | basename ] }}"
when: Layer == 'APP'
with_items:
- "{{ Source_Filenames.split(',') }}"
vars:
fpath_APP: []
- debug: var=fpath_{{ Layer }}
I'm getting the below syntax error running the yml.
$ ansible-playbook /app/helpA.yml --tags validate -e

I'm on the latest version on of ansible and python 2.7.5
I have a path which looks like this -
base_dir/123/path/to/G\$/subdirectory/html/
When I try to set this path in Ansible playbook, it throws error. If add \$ to escape '\', it throws unexpected failure error.
Playbkook -
- hosts: localhost
vars:
account_id: 123
tasks:
- name: Add \ to path
debug:
var: "base_dir/{{ account_id }}/path/to/G\\$/subdirectory/html/"

As explained in the debug module documentation, the var option is expecting a variable name, not a scalar for output. You are getting an error because \ is not expected in a variable name. Running the playbook with -vvv will give you a little more explanations.
In this case you need to use the msg option.
- hosts: localhost
gather_facts: false
vars:
account_id: 123
tasks:
- name: Add \ to path
debug:
msg: "base_dir/{{ account_id }}/path/to/G\\$/subdirectory/html/"
Result
PLAY [localhost] ***************************************************************
TASK [Add \ to path] ***********************************************************
ok: [localhost] => {
"msg": "base_dir/123/path/to/G\\$/subdirectory/html/"
}
PLAY RECAP *********************************************************************
localhost : ok=1 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
The next option is to use the Single-Quoted Style. See the example below
- hosts: localhost
vars:
my_dir1: "/scratch/tmp/G1\\$"
my_dir2: '/scratch/tmp/G2\$'
tasks:
- file:
state: directory
path: "{{ item }}"
loop:
- "{{ my_dir1 }}"
- "{{ my_dir2 }}"
# ls -1 /scratch/tmp/
'G1\$'
'G2\$'
In ansible what i require is to check for a file is available on two hosts. But if the file is available on even one host i need to cancel the task on other host and move onto the next task. The reason why i require this is because a the next task can only be done if that particular file is available and that file can be randomly written to any of the hosts.
The following play does exactly what you want:
---
- hosts:
- server1
- server2
gather_facts: False
vars:
file_name: 'foo.bar'
tasks:
- name: wait for file
wait_for:
path: '{{ file_name }}'
state: present
timeout: 30
ignore_errors: True
- name: stat
stat:
path: '{{ file_name }}'
register: result
- name: next
debug:
msg: "File {{ file_name }} available on {{ ansible_host }}"
when: result.stat.isreg is defined and result.stat.isreg
The output is:
PLAY [server1,server2] *********************************************************
TASK [wait for file] ***********************************************************
ok: [server1]
fatal: [server2]: FAILED! => {"changed": false, "elapsed": 3, "msg": "Timeout when waiting for file foo.bar"}
...ignoring
TASK [stat] ********************************************************************
ok: [server1]
ok: [server2]
TASK [next] ********************************************************************
skipping: [server2]
ok: [server1] => {
"msg": "File foo.bar available on server1"
}
PLAY RECAP *********************************************************************
server1 : ok=3 changed=0 unreachable=0 failed=0
server2 : ok=0 changed=0 unreachable=0 failed=0
You can use the stat module to check the status like below and for also you can add the serial:1 below hosts: in your playbook
stat:
path: /path/to/something
register: p
debug:
msg: "Path exists and is a directory"
when: p.stat.isdir is defined and p.stat.isdir
