That's a pretty vague question.  Could you tell us what you've done and 
where you are stuck?

[ansible-project] Re: Ansible WinRM dont run concurrent process

[Dylan Martin]

How are you making them concurrent?  IE what does your play look like?  

If you have three conventional separate ansible tasks, that won't work.  
You'd need a single task that launches all 3 or use async.

https://docs.ansible.com/ansible/latest/user_guide/playbooks_async.html

If you're already using async, show us your playbook.

[ansible-project] Re: Quick question- how to run ansible playbook on Saturday night at 12 PM and save the output in amazon s3 bucket

[Dylan Martin]

What environment are you in?

I have linux servers in a datacenter.  I'd write a shell script to run the 
play, output to a file and copy the file to s3.  Then I'd use cron to 
schedule the job.  Of course, you'd need to use a passwordless ssh key or 
set up ssh-agent ahead of time to work with cron, which can be a little 
tricky.

So, basically how you'd schedule any task, with extra attention paid to the 
ssh auth.

[ansible-project] waits for password when I don't want it to

[Dylan Martin]

Hi all.

I have an environment with several hundred unreliable machines.  Sometimes 
they're just dead, sometimes they're misconfigured.   I always encounter 
some where the keys in my ssh-agent don't work and it prompts me to enter 
the password and it waits for me to hit enter a bunch of times before the 
play will proceed.  

Is there a way to configure ssh or ansible to just fail when this happens?  
I sometimes will run plays with password auth instead of ssh keys, so I 
don't want to completely disable that.

Thanks!

[ansible-project] win_timezone change does not survive reboot

[Dylan Martin]

My timezone was Pacific Standard Time.  I used the win_timezone module to 
set it to UTC.  I appeared to work.  The TZ was UTC.  After reboot, the TZ 
was Pacific Standard Time again.

Is this expected?  Is there a way to make TZ change persist after reboot?

[ansible-project] Weird Windows Path Problem

[Dylan Martin]

Hi, I'm using Ansible 2.8 on Ubuntu and I'm trying to make a directory to a 
windows box.  

But wait!  I hear you say, what about 
https://docs.ansible.com/ansible/latest/user_guide/windows_usage.html#path-formatting-for-windows
 
?
Read it.  

If I use an unquoted or single quoted string, like so:

 - win_file:
   path: C:\foo

I get 

"path C:\\foo will not be created"

If I use a double quoted string, like so:

  - win_file:
path: "C:\foo"

I get 

"Get-AnsibleParam: Parameter 'path' has an invalid path 'C:\foo' specified."

Help!

I've used parted and lvm (lvg & lvol) to set up machines, but I recently

[ansible-project] Re: Management of multiple exclusive authorized_keys entries, for multiple users

[Dylan Martin]

Right of the top of my head, put user specific stuff in a dict in  vars 
file (or conditional include a file for each user), so you have a dict 
that's populated differently based on the value of a "user" var.

Then in a dependencies section in a meta/main.yaml, you just do
{ role: sshrolename, user: username }
{ role: sshrolename. user: otherusername }

Of course that's gonna be slow, so you could write your role to want a list 
of users, and then pass a list in the meta/main.yaml file.  You can always 
pass a list with one item.

[ansible-project] Re: FAILED => Missing sudo password when NO SUDO PASSWORD is needed

[Dylan Martin]

Oh, another important thing about sudo!  Don't use wildcards in a sudoers 
file if you care about the args your user passes!  You cannot specify how 
many args are allowed, so no matter how tightly you construct the wildcard, 
the user can always add more args.  Either use literal commands in the 
sudoers file or use a wrapper that sanitizes the args and have sudo call 
the wrapper.

[ansible-project] Role do something after handler?

[Dylan Martin]

Hi all, I have a strange one that I hope you can help me with.

I'm trying to make a role for systemd service unit files.  This is the 
newfangled replacement for good ol' sysV init scripts in Rhel7, any recent 
Fedora and a lot of other linux distros.

The workflow is supposed to go something like this.

1) edit/install a unit file, like /etc/systemd/system/myservice.service
2) run systemctl daemon-reload 
3) run systemctl enable myservice
4) run systemctl start myservice

daemon-reload tells the systemd daemon to re-read the unit files so it will 
know you changed something

In ansible, I interpret that as looking like

1) template out unit file
2) notify daemon-reload handler if unit file changed
3) service enable=true state=started name=myservice

The problem is, if I've changed the unit file, the daemon-reload runs after 
the service enable/start, so systemd doesn't know to re-read the unit file 
before trying to start/enable the service.

I could just make it run daemon-reload every time the role runs, which 
kindof sucks.  Also, if I'm installing a boatload of unit files, I'd like 
to do a daemon-reload only once to get them all.  I could make the 
daemon-reload a normal task that only runs when the template changes, but 
that means I'd be running the daemon-reload once for every unit file, which 
sucks in the case where I'm installing a boatload of them.  I looked at 
post_task, but that's not for roles.  

Does anyone know a good way to do this?

Thanks!

[ansible-project] ansible-galaxy init and metadata values

[Dylan Martin]

Hi everyone.  I expected this functionality to exist, but I can't find it 
so either it does exist and someone can gently point me toward the document 
I missed or it doesn't exist and we might want to talk about weather it 
should exist.

I expected I could write a file like ~/.ansible/galaxy-defaults.yaml that 
would look like this:

---
author: me
company: me.com
license: my license
... etc ...

and then when I run ansible-galaxy init somenewrole, my 
somenewrole/meta/main.yaml and my somenewrole/README.md files would have 
that info already templated in.

Does that make sense?  I'm a perl guy (ducks head, waits for laughter to 
subside) and I'm used to using Module::Starter where you can put values in 
~/.module-starter/config and those values get templated into new modules.

If I'm still not making sense, here's Module::Starter 


Thanks!  Sorry if I missed something in the docs that should have shown me 
how to do this!

[ansible-project] compare results of two tasks?

[Dylan Martin]

I've looked for this and haven't found it, so if this is documented 
elsewhere, I do apologize.

I want to compare the md5 sums of two copies of a list of files.  IE there 
are two locations which should have the same exact files, and I want to 
compare them.  Not all files in the two locations need to match and I have 
a list of the files that should match

- stat: foo/{{ item }}
  with-items: list_of_files
  register: foo_stat
- stat: bar/{{ item }}
  with-items: list_of_files
  register: bar_stat
- fail: msg="bar/{{ item }} doesn't match foo/{{ item }}"
  with-items: list_of_files
  when: ??

Thanks!
-Dylan

[ansible-project] checking if a dynamically selected variable is defined?

[Dylan Martin]

Hi all.

I often write plays that require extra vars.  eg "ansible-playbook user -e 
user=bob"

In that play, I'll start off with 

- fail: msg="You forgot to set the user variable"
  when: user is not defined or user == ""

And I was thinking it might be nice to write an external, reusable play 
that would be called like this:

- include: check_defined.yaml checkvar=user

and look something like this


- hosts: all
  tasks:
  - fail: msg="{{ you forgot to specify a checkvar }}"
when: checkvar is not defined or checkvar == ""
  - fail: msg="you forgot to set {{ checkvar }}"
when: ?? is not defined or ?? == ""

The first fail is just to catch myself if I include check_defined.yaml 
without setting checkvar
the second fail is the thing I actually am curious about.  The ? are 
the bits I don't know how to do.

Okay, I admit this is pretty silly, since I could write the is not defined 
checks for about 20 playbooks in the time it took to write this email.  And 
including the play is one line when the play itself ( or task) is 2.  But 
still, I think I'd understand ansible and jinja2 better if I knew the 
answer to this.  

Thanks

[ansible-project] Script to migrate old style vars to new style?

[Dylan Martin]

Hi all, I might be taking a big bunch of playbooks that use old style vars 
and changing them to use new style vars.  Is there a script or other 
automation that can make that easier?  Any other advice?

Thanks!
