I want to run the ansible setup module, by declaring a specific host.
I am using Windows 10 machine , with windows subsystem for linux where ansible is installed.
I can run the setup module when using localhost, ie:
ansible localhost -m setup
I can run it when using the ansible.cfg file I use from one virtual environment, against a virtual machine ie:
ansible TestVm -m setup
In another virtual environment i have installed ansible without setting up an ansible.cfg file, and my hosts.yml file is in the windows (not the WSL filesystem).
No matter which directory i switch, I cannot run the setup module using for instance:
ansible -i inventory -m setup
.
Is there a way to run setup without a configuration file and if yes what part of the call am i missing?
Try this:
ansible all -i inventory -m setup
Where the inventory is a directory with at least the hosts.yml file.
And this an example of hosts.yml
all:
hosts:
192.168.2.9:
192.168.2.3:
192.168.2.4:
Also before any of these you must have added pywinrm:
pip install pywinrm

I want to run the os_server module on a target host which has a virtual enviroment where openstacksdk is installed. If I try to run the script as shown below it results in a error "conflicting action statements: virtualenv, os_server". How can I specify a virtual enviroment correctly so that ansible uses it? I don't want to install openstacksdk globally and just use the venv.
- name: Create Server
virtualenv: "/home/user/otc2/bin/activate"
os_server:
state: present
auto_ip: false
...
You would set the ansible_python_interpreter hostvar for that host to point to the python binary inside the virtualenv on the remote machine, which appears to be /home/user/otc2/bin/python based on your posted snippet
I've been looking into attempting to get ansible to use python3 on remote targets, in order to run playbooks against them, however, simply running a playbook against a target with python3 installed fails with the error message:
"/bin/sh: 1: /usr/bin/python: not found\r\n"
Looking for answers to this online only seem to discuss configuring ansible on the host to use python3 rather than the remote. Is it possible to configure the remote to use python3 rather than 2?
You can set the ansible_python_interpreter variable to tell Ansible which version of Python to use. You can set this globally, as C. Dodds has suggested in their answer, but it generally makes more sense to set this as a per-host inventory variable. E.g., using a YAML inventory:
all:
hosts:
myhost:
ansible_python_interpreter: /usr/bin/python3
Or using an ini-style inventory:
myhost ansible_python_interpreter=/usr/bin/python3
And of course you can set this per-hostgroup if you have several hosts that require the same configuration.
This is discussed in the Ansible documentation.
Adding the argument "-e 'ansible_python_interpreter=/usr/bin/python3'" was the solution to this:
ansible-playbook sample-playbook.yml -e 'ansible_python_interpreter=/usr/bin/python3'
Installed Ansible AWX on CentOS 7 without docker. Want to add remote linux hosts(without password) to AWX and run play books and get the results. How to do it? Can any one help. One or two hosts I can add it in web page. How to add 100 remote hosts to AWX. Is there any AWX back end scripting is there to add N number of remote hosts to AWX? Thanks.
Create inventory file in git. Add it to projects in AWX. Create inventory with source as inventory project in AWX.
Your ssh keys will have to be stored in awx credentials.
Create inventory with credentials via web interface.
Sign in hosts with AWX via ssh.
ssh user#hostname
Sign in container awx_tasks
docker exec -it awx_task sh
Create or copy file with hosts ip/hostname
# cat hosts.ini
10.0.0.1
10.0.0.2
#
Add multiple hosts from file to inventory
awx-manage inventory_import \
--inventory-name my-inventory \
--source hosts.ini
Worked in my case, AWX 17.0.1
I need to know if it's possible to call / execute ansible playbooks from the target machine. I think i saw a vendor do it or at least something similar. they downloaded a script and it did ran the playbook.
if this is possible how would it be done?
my goal is to run ansible as a centralized server in aws to perform tasks in mulitple environments. most are behind firewalls, any reccomendations/thoughts would be appreciated.
Sure. If your host will install Ansible on target and feed it with all the playbooks the you can run it as any other executable. Should you do that is another story but technically there's no obstacle.
You can run ansible and ansible playbook as you would any other binary on the target's $PATH, so any tool that facilitates running remote commands would work.
Because you are in AWS, one way might be to use AWS System's Manager.
If you wanted to use Ansible itself to do this you could use the shell or command modules:
- hosts: target
become: false
gather_facts: false
tasks:
- name: ansible in ansible
command: ansible --version
- name: ansible-playbook in ansible
command: ansible-playbook --version
Though, as with any situation where you reach for the shell or command modules, you have to be vigilant to maintain playbook idempotency yourself.
If you're requirement is just the ability to execute Ansible commands remotely, you might look into AWX which is the upstream project for Red Hat's Ansible Tower. It wraps ansible in a nice user interface to allow you to trigger Ansible playbooks remotely and with nice-to-haves like RBAC.
If you're ok with executing tasks remotely over ssh take a look at Sparrowdo it has out of the box facilities to run bash scripts ( read ansible executable ) remotely from one master host to another. Or you can even use it to install all the ansible dependencies or whatever you need to do for your scope.
When I try running this Ansible command - ansible testserver -m ping it works just fine, but when I try this command - ansible webservers -m ping I get the following error - ERROR! Specified hosts options do not match any hosts.
My host file looks like this -
[webservers]
testserver ansible_ssh_host=127.0.0.1 ansible_ssh_port=2222
What could be the problem? Why can ansible recognize the host in question and not the host group?
I've tried changing the file to make sure ansible is reading from this file specifically, and made sure this is the case, so this is not a problem of reading configurations from another file I am not aware of.
I've also tried using the solutions specified in Why Ansible skips hosts group and does nothing but it seems like a different problem with a different solution.
EDIT - added my anisble.cfg file, to point out I've already made all the vagrant specific configurations.
[defaults]
inventory = ./ansible_hosts
roles_path = ./ansible_roles
remote_user = vagrant
private_key_file = .vagrant/machine/default/virtualbox/private_key
host_key_checking = False
I think you are working with the vagrant and you need to ping like this:
ansible -i your-inventory-file webservers -m ping -u vagrant -k
Why your ping fail prevously:
ansible try to connect to vagrant machine using local login user and it doesn't exist on the vagrant machine
it also need password for the vagrant user which is also vagrant.
Hope that help you.
