I have a playbook which has multiple roles and serial setup so that fist it's running on one machine then on the rest of them. In one of the roles I have the following tasks:
- name: getting dbnodes IP addresses
local_action: shell echo "{% for host in groups['dbnodes'] %}{{ hostvars[host]['ansible_eth0']['ipv4']['address'] }},{% endfor %}"
run_once: true
register: IPS
Basically what I want to do is to gather the IP addresses of all the hosts and register it with IPS for further usage. But the task is failing because of the serial (I think) with the following error.
TASK [dbcluster : getting dbnodes IP addresses] ********************************
fatal: [162.220.52.190]: FAILED! => {"failed": true, "msg": "the field 'action' has an invalid value, which appears to include a variable that is undefined. The error was: 'dict object' has no attribute 'ansible_eth0'\n\nThe error appears to have been in '/root/tenon-delivery/ansible/roles/dbcluster/tasks/main.yml': line 52, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: getting dbnodes IP addresses\n ^ here\n"}
While running ansible dbnode -s setup I can see that the ansible_eth0 has a proper value. I don't understand why it is saying that it's undefined.
Any idea how to gather the facts on all machines in the same time while still having the option several tasks/handlers still being done serialized.
ansible_eth0 fact may be unknown at the time of your task run.
You may want to add fact gathering play at the very top of your playbook:
- hosts: dbnodes
gather_facts: yes
tasks:
- debug: msg="facts gathering"
- hosts: othernodes
tasks:
- name: getting dbnodes IP addresses

I want to use content in .txt file and I tried to debug content using following code.
- name: Find .txt files
find:
paths: "{{output_path}}"
patterns: '*.txt,'
register: file_path
- name: Show content
debug:
msg: "{{lookup('file', item.path)}}"
with_items: "{{file_path.files}}"
But I got this error.
[WARNING]: Unable to find '/path/file.txt' in expected paths (use -vvvvv to see paths)
TASK [Show content] ******************************************************
fatal: [10.0.2.40]: FAILED! => {"msg": "An unhandled exception occurred
while running the lookup plugin 'file'. Error was a <class 'ansible.errors.AnsibleError'>,
original message: could not locate file in lookup: /path/file.txt"}
How I fix this error?
There's nothing inherently wrong with your playbook, except that you have a comma inside the find pattern (this might be just a typo, but you should check it out) if you are running this playbook locally. In the case that you are running this playbook on a remote server, you should try to use a different module like slurp or fetch.
slurp works great if you need to keep the contents of the txt in memory to use it on another task. Bear in mind that ansible will encode the slurp module's output in base64, so you should decode it first when you want to use it. From the module example page:.`
- name: Find out what the remote machine's mounts are
ansible.builtin.slurp:
src: /proc/mounts
register: mounts
- name: Print returned information
ansible.builtin.debug:
msg: "{{ mounts['content'] | b64decode }}"
You can verify what I am saying with the following example:
I tried replicating your situation locally. On a temporary folder, I run the following command to populate it with many .txt files:
echo {001..099} > file_{001..099}.txt
Then I wrote the same playbook that you provided:
#
# show_contents.yml
#
- hosts: localhost
gather_facts: no
tasks:
- name: Find .txt files
find:
paths: "{{ output_files }}"
patterns: "*.txt"
register: file_path
- name: Debug the file_path variable
debug:
var: file_path
- name: Get the contents of the files using debug
debug:
msg: "{{ lookup('file', item.path ) }}"
loop: "{{ file_path.files }}"
If you run this playbook, passing the appropriate output_files variable with --extra-vars, the playbook works fine.
ansible-playbook show_contents.yml --extra-vars "output_files=/tmp/ansible"
You'll see that the playbook runs without an issue. Try using this example to figure out what you are trying to achieve. And then modify the playbook to use some of the previously mentioned modules when working with remote servers.
I want to run ansible role by iterating it through count of value that I am providing.
Say for example: Below is the Ansible role main.yml, in which I include a yaml file to execute where this included yaml file should execute the number of times with the loop which I have.
Here is my small piece of code where I used with_sequence module. But if you have any other suggestion to run the create_db.yml file multiple times, please share with or how to loop through with the current code that I have.
Could someone help me on this?

# tasks file for create db
- hosts: localhost
become: yes
tasks:
- include: create_db.yml
with_sequence: count = 2
I am getting below error while executing the playbook
fatal: [localhost]: FAILED! => {"msg": "unrecognized arguments to with_sequence: [u'_raw_params']"}
As mentioned in the comments, the use case for running the same task file twice without any change in parameters is not clear. But the error...
unrecognized arguments to with_sequence
... indicates that the syntax for specifying count is incorrect. Please note that there should be no spaces around =, i.e. count=2.
tasks:
- include: create_db.yml
with_sequence: count=2
I need to copy the contents of a file in windows to a variable.
I tried as below, but getting error.
- name: test
set_fact:
new_var: "{{lookup('file', 'C:\\temp\\test.csv') }}"
Error is:
"An unhandled exception occurred while running the lookup plugin 'file'. Error was a , original message: could not locate file in lookup: C:\temp\test.csv"
The file is present in the remote windows server. Please let me know what is wrong here or please suggest an alternative way.
I had the same problem, didn't get it to work with the lookup file plugin.
As an alternative I did:
- name: get content
win_shell: 'type C:\Temp\ansible.readme'
register: content
- name: write content
debug:
msg: "{{ content.stdout_lines }} "
The reason the OPs solution doesnt work, is that the nlookup is run on the localhost (the ansible server, where the playbook is stored). nlookup can be used to get file content as either a "file" or as a "template". Template will replace {{ variables }} with a variable. File will just read the file to a variable.
C:\temp\test.csv does not exist in the playbook folder, hence it fails.
amutter's solution works by running a windows command and then passing the output into a variable. The command that he ran is
# This runs the windows command 'type' to read the contents of the file and return the value in the console. The console output is passed into the variable content
- name: get content
win_shell: 'type C:\Temp\ansible.readme'
register: content
# The content.stdout is used to return the whole console output. stdout_lines can be used to use a specific line as it is an array of lines
- name: write content
debug:
msg: "{{ content.stdout }} "
Env is: Ansible 1.9.4 or 1.9.2, Linux CentOS 6.5
I have a role build where:
$ cat roles/build/defaults/main.yml:

In my workspace: hosts file (inventory) contains:
[ansible_servers]
server01.project.jenkins
site.yml (playbook) contains:
---
- hosts: ansible_servers
sudo: yes
roles:
- build
I'm running the following command:
$ ansible-playbook site.yml -i hosts -u confman --private-key ${DEPLOYER_KEY_FILE} -t koba
I'm getting the following error and for some reason, become_user in Ansible while using Ansible loop: with_fileglob is NOT using ~ (home directory) of confman user (which is set in variable {{ build_user }}, instead of that, it's picking my own user ID (c123456).
In the console output for debug action, it's clear that the user (due to become_user) is confman and value of tools_dir variable is ~/tools.

As per the error above, the file it's trying for variable item is /user/home/c123456/tools/vmwaretools-lib-1.0.8-SNAPSHOT/lib/insecure_private_key but there's no such file inside my user ID's home directory. But, this file does exist for user confman's home directory.
i.e. the following file exists.
/user/home/confman/tools/vmwaretools-lib-1.0.7-SNAPSHOT/lib/insecure_private_key
/user/home/confman/tools/vmwaretools-lib-1.0.7/lib/insecure_private_key
/user/home/confman/tools/vmwaretools-lib-1.0.8-SNAPSHOT/lib/insecure_private_key
All, I want is to iterate of these files in ~confman/tools/vmwaretools-lib-*/.. location containing the private key file and change the permission but using "with_fileglob" become_user to set the user during an action is NOT working.
If I comment out the with_fileglob section and use/uncomment with_items section in the tasks/main.yml, then it (become_user) works fine and picks ~confman (instead of ~c123456) and gives the following output:
TASK: [build | Set private key file access] ***********************************
changed: [server01.project.jenkins] => (item=~/tools/vmwaretools/lib/insecure_private_key)
One strange thing I found is, there is no user c123456 on the target machine (server01.project.jenkins) and that's telling me that with_fileglob is using the source/local/master Ansible machine (where I'm running ansible-playbook command) to find the GLOB Pattern (instead of finding / running it over SSH on server01.project.jenkins server), It's true that on local/source Ansible machine, I'm logged in as c123456. Strange thing is, in the OUTPUT, it still shows the target machine but pattern path is coming from source machine as per the output above.
failed: [server01.project.jenkins]
Any idea! what I'm missing here? Thanks.
PS:
- I don't want to set tools_dir: "~{{ build_user }}/tools" or hardcode it as a user can pass tools_dir variable at command line (while running ansible-playbook command using -e / --extra-vars "tools_dir=/production/slave/tools"
Further researching it, I found with_fileglob is for List of local files to iterate over, described using shell fileglob notation (e.g., /playbooks/files/fooapp/*) then, what should I use to iterate over on target/remote server (server01.project.jenkins in my case) using pattern match (fileglob)?
Using with_fileglob, it'll always run on the local/source/master machine where you are running ansible-playbook/ansible. Ansible docs for Loops doesn't clarifies this info (http://docs.ansible.com/ansible/playbooks_loops.html#id4) but I found this clarification here: https://github.com/lorin/ansible-quickref
Thus, while looking for the pattern, it's picking the ~ for user c123456.
Console output is showing [server01.project.jenkins] as it's a different processing/step to read what's there in the inventory/hosts file.
I tried to use with_lines as well as per this post: ansible: Is there something like with_fileglobs for files on remote machine?
But, when I tried the following, it still didn't work i.e. read the pattern on local machine instead of target machine (Ansible docs tells with_items doesn't run on local machine but on the controlling machine):
file: path="{{ item }}" ....
with_items: ls -1 {{ tools_dir }}/vmwaretools-lib-*/lib/insecure_private_key
become_user: {{ build_user }}
Finally to solve the issue, I just went on the plain OS command round using shell (again, this might not be a very good solution if the target env is not a Linux type OS) but for now I'm good.
- name: Set private key file access
shell: "chmod 0400 {{ tools_dir }}/vmtools-lib-*/lib/insecure_private_key"
become_user: "{{ build_user }}"

I am working on a project using Ansible which requires me to write some data to a file using one playbook and then read the data from the same file using another playbook.
The playbook will be something like this
test1.yml
---
- hosts: localhost
connection: local
gather_facts: no
tasks:
- name: Writing data to test file
local_action: shell echo "data:" {{ 100 |random(step=10) }} > test.txt
- include: test2.yml
and would need to read it using test2.yml
---
- hosts: localhost
connection: local
gather_facts: no
vars_files:
- test.txt
tasks:
- name: Writing data to test file
local_action: shell echo "{{ data }}" > result.txt
However,
The second playbook is not able to read the latest data being posted by the first playbook.
If I view the data written in test.txt and result.txt they both are different. Is there a way to achieve consistency between the results of playbook calls ????
Are those two playbooks called separately? If they are included inside a master playbook, then this would explain it. All includes in the master playbook are resolved before execution, so Ansible would already have read both playbooks and the vars_file before any of them gets executed. You should be able to solve this by dynamically including the vars file during play with the include_vars module.
If I was wrong with my assumption and you're not including the playbooks in a parent playbook: What exactly do you mean by "different"? Is it completely different data or is it a formatting issue? I'm puzzled how data in general could not be consistent between calls. There is no magic in writing to and reading from a file. That should theoretically work.
