Ansible 2.4.2.0 on CentOS 7--ping module isn't working

Dont' pass ansible_host= in the command line. That's defined in your inventory file. You also don't need to add that in your inventory file at all since you've defined it in your /etc/hosts file. I never add the password in the inventory. If I don't have a key on the other end I just pass -k in the command. So you would do this:

ansible -i inventory ansible-target1 -m ping -k

Also make sure every host is on a separate line in your inventory. I noticed you only did > instead of >>. You could have only put one host in, but figured I'd mention it just in case.

Also 2.4.2 is kind of old. Some things are being deprecated soon, so you will want to either install from EPEL or use pip to pull in a newer version.

Another "CentOS problem" that "doesn't exist"

Well it's weird. Idk if CentOS hasn't caught up with RHEL yet or what's going on. Ansible is at 2.7 in RHEL. I have no idea why it's lagging so far behind in CentOS.

But even Fedora lags behind a little. It's getting better but I've seen it as far as 2 releases behind before.

@black3dynamite That looks so weird to me

shouldn't the host be ansible_host=hostname ? Did they change that?

Please post your inventory well formatted as code. It should contain a list of targets and should be passed to ansible with the -i flag. Also check the docs: https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html

This is a basic ping check with a basic inventory file. Originally it was this but I have removed the ssh password portion.

ansible-target1 ansible_host=192.168.1.208 ansible_ssh_pass=password
ansible-target2 ansible_host=192.168.1.209 ansible_ssh_pass=password

God you're handsome.

Time to screw around with YAML.

Or in Salt:

salt pcname test.ping

Or in Salt:

salt pcname test.ping

It's much simpler if you have your ansible.cfg and keys set up. Then it's just ansible server -m ping.

This is like trying to use Salt without having certs set up (or SSH keys in the case of salt-ssh)

If you want to use ssh as a transport, but not needed or why you'd choose Salt. If that's the case then I'd rather want to use Ansible.

I want saying you should. Just once things are set up properly they are both (Ansible and Salt) very similar in ease of use.

I always download it from upstream

@stacksofplates How are you organizing? I have playbooks and inventory together in the same directory right now. Seems bad. Also, are you using an IDE?

Another way to do this ping test:

pingtest.yml

-
  name: Test connectivity to target servers
  hosts: all
  tasks:
   - name: Ping test
     ping:

Here are some best practices for directory layouts.

I'll give you a layout this afternoon. I keep my inventory with my playbooks but roles have their own repositories.

So I have my playbooks set up like this (for stuff at home). I've seen people put playbooks in a directory which is fine as well. It's just annoying because your ansible.cfg has to be in relation to your playbooks so you had to mess around with softlinks to get it to work that way.

Roles (ones I've written) are in their own directory:

Here's my default ansible.cfg which I store with the playbooks:

[defaults]
inventory           = inventory
roles_path          = roles
retry_files_enabled = False
pipelining          = True
library             = library
forks               = 50
callback_whitelist = profile_roles

And then in the inventory directory I have a prod and dev file that contain all of the groups and hosts.

Also, are you using an IDE?

I switch between VS Code and Vim. However I always turn on Vim mode in anything. I also have things like jj mapped to Esc and AA mapped to drop me to the end of a line in insert mode to make things easier.

stacksofplates

So to clarify, playbooks is it's own private repository. Then the roles are public repos. In the roles directory in the playbooks repo I have a single file called requirements.yml. This tells Ansible what roles to install for me before it runs.

It contains entries like this:

- src: https://gitlab.com/hooksie1/ansible-firewalld.git
  name: firewalld
  scm: git
  version: master

I've been using Jenkins to run my Ansible stuff so I have a build step that runs ansible-galaxy install -r roles/requirements.yml before it runs the playbook. That installs all of the roles for you. As a side note, if you're using Tower it will download the roles automatically if it sees that file exists.

Here's the build steps in Jenkins:

I also have started including a Makefile to do the same thing. That way you can just run make clean and make roles to remove and re-download them.

That’s awesome.
