[ansible-project] Ansible to adopt molecule and ansible-lint projects.

[Timothy Appnel]

To support the continued growth of Ansible we are expanding Ansible Galaxy
to include new functionality and tooling. A goal of this expansion is to
provide a minimum viable level of quality checks for content on Ansible
Galaxy. One of the first steps we are taking is adopting molecule and
ansible-lint as official Red Hat Ansible projects.

ansible-lint and molecule are great tools. They've been built and tested by
the community that we see as essential parts of enhancing development of
Ansible automation. By adopting these tools, Red Hat intends to invest
resources working with the community to make them even better. We are very
excited to integrate ansible-lint and molecule with the rest of the Ansible
projects.

We would like to thank Cisco, specifically John Dewey, for their work on
molecule. Cisco's willingness to transfer this project over to the Red Hat
Ansible team lends great credence to their contributions to the open source
ecosystem. We also want to thank Will Thames, the maintainer of
ansible-lint, for his contributions developing a tool that has done so much
for Playbook authors. We look forward to working with the communities that
have made these projects what they are. We want to share further
improvements with the broader Ansible community as well.

So what happens now? The repos will be migrated to the Ansible organization
on GitHub. The transition and roadmap will be iterated on gradually.
Ideally, the community will help guide our decision making as we go forward.

If you’re not familiar with these projects I encourage you to become more
familiar with them and how they can make automating with Ansible even more
simple and frictionless.

[ansible-project] Re: [ansible-devel] Re: Proposal for fixing playbooks with dynamic include problems

[Timothy Appnel]

@jimi-c: Is it possible to evaluate static includes after the setup module
runs to gathering facts? The most common use pattern I see in users plays
and roles are dynamic includes that define the filename based on a fact
like ansible_os_family. Collecting the fact before evaluating includes
would make things even more seamless for users.

Re: [ansible-project] How do I use status to assign variables

[Timothy Appnel]

Essentially. Assign your hosts to a dev, test or prod group and set
variables that apply to those groups.

Re: [ansible-project] When to call a specific task from a role?

[Timothy Appnel]

This is a question I've pondered in my own work. There is no one specific
or recommended way Ansible prescribes for doing this. What follows are my
own personal thoughts and mine alone.

You can do separate role as you suggest. Not ideal because it puts to much
distance between closely related functionality for my liking.

You could tag tasks one or the other -- however you must remember to pass a
tag. No sure this is practical in that it's too easy to mess up.

You can implement something with some combinations of params/variables,
conditionals, includes and/or blocks. This is one I think has the most
promise though the number of ways this could be implemented are pretty
extensive in number.

Re: [ansible-project] Re: Can't find boto for ansible EC2 module

[Timothy Appnel]

Ansible doesn't use a fixed /usr/bin/python necessarily. If you set a
different python interpreter via your inventory as Justin did here and keep
the remotes files, you'll notice that Ansible has replaced with
/usr/bin/python with the python interpreter you have in your inventory.

*> I don't see why, when /usr/bin/env python will mostly be the correct
python, it's still being enforced to use /usr/bin/python :/ .*

The keyword in your sentence here is "mostly." Ansible needs to be using
the intended python interpreter "*always*." I've worked in environments
where the default python was way out of date and the modern version was in
an alternate location. Because Ansible was forced to use a service account
that did not have a profile to alter the PATH, we were forced explictly
specify the python interpreter and let Ansible do it's thing. I've also
worked in environments where python was in different alternate locations.

Think of #!/usr/bin/python as just a placeholder, albeit it a functional
one if left as is.

Hope that helps answer your question.

Re: [ansible-project] Ansible: How to use a Variable as an Index?

[Timothy Appnel]

That is a good way of thinking of explaining it in the context of Ansible
-- start Jinja, stop Jinja. At the same time, how would you have
represented this in a Jinja template? Jinja doesn't allow for nested
mustaches in any context that I am aware of.

I'm sure a patch to the docs to make light of this would be appreciated.

return any groups or group variables.

The dynamic inventory plugin API is a coarse-grained one that slurps in
everything it can get from the inventory source. There are many reasons for
that such as tasks that reference other host resources not targeted by the
play.

Re: [ansible-project] Ansible: How to use a Variable as an Index?

Don't use nested mustaches. In other words try this:

cvmip: "{{ nics[num].ip }}"

Re: [ansible-project] delegate_to from inventory? copy between remote hosts

[Timothy Appnel]

Try wrapping your mons variable in {{ }} like this...

delegate_to: {{ mons[0] }}


I'm pretty sure without them your variable is being interpreted as a
literal.

Re: [ansible-project] Re: variable set to a default value in play vars unexpectedly becomes not the default value

[Timothy Appnel]

I realize your are using includes. I was pointing out that you want to use
roles for the benefit of the namespacing protection that roles have and
includes do not. From what I see this is correct behavior for what you've
implemented and not a bug. A role should give you the separate variable
namespace scope you seem to be expecting.

Re: [ansible-project] Importing custom python library from ansible custom module

[Timothy Appnel]

I'm glad you were able to work something out and I was helpful. A couple of
quick added thoughts on this.

I wouldn't recommend just dropping your library in to just /tmp to avoid a
potential conflict with another job or process. Perhaps create a separate
directory like the name of your project or playbook under tmp and store it
there? I think create a specific directory helps avoid this.

I also wouldn't recommend embedding a library path in your custom module
for maintainability. It's working for you now, but the thought of having to
have that path line up in two different places make me uneasy. I used the
environment arg and appended the path to our libraries to PYTHONPATH.
Everything is in one place: the playbook. A var to hold the path (you can
use Ansible facts to really create a unique path that won't get tread on),
the path create, the copy, the environment setting. Change it in one place
and the change probates thru.

Just some food for thought.

Re: [ansible-project] Importing custom python library from ansible custom module

I didn't give up at all. Far from it! I started working for Ansible.

Last I spoke to my former co-workers they are still using options 2 that I
setup because they do not have the ability to install python libraries in
the default library path.

Re: [ansible-project] Importing custom python library from ansible custom module

[Timothy Appnel]

In a previous life I've had to do what you are attempting. Ansible will not
automatically know to install dependencies like your custom library for
you.That is up to you to handle. There are two ways I've gone about it
resolving this:

1) Install said libraries in your default python library path on each
remote box.
2) Copy/install your libraries to an alternate path location (could be one
time could be an earlier task of the play) and use the environment argument
on the task that uses your custom module to append said library path to
PYTHONPATH.

Not knowing what is in your infile.py, you may want to consider embedding
that library in the module if it's a single library file that's not too
complex. I didn't personally use this approach, though I considered it, in
my own because the library files had other usage outside of my custom
Ansible module and I didn't want to play around keeping the code in sync.

Hope that helps.

[ansible-project] lookup -csvfile - special character delimiter

[Timothy Appnel]

Looks like there are a couple of things getting in your way. 

The first is that the YAML parser thinks the : (colon without escaping or 
quoting) is a misplaced key/value delimiter. If you put that in double quotes 
it passes thru to the next issue that being the csvfile lookup plugin makes a 
call to csvfile.reader with the delimiter string still wrapped in quotes. The 
delimiter param must be a single character causing another error. 

I guess there are a few ways to go about addressing this in the core. 

One is to have special string like COLON (like TAB) that gets converted to its 
single character form. 

The other is to detect the delimiter string is more than a single character and 
assume that it's probably quoted. 

I like the later solution because it handles any sort of quoted character 
someone may throw at it. I'm not fond of the idea of introducing a regex for an 
edge case where there wheren't any before. Perhaps a len and split combo like 
this would suffice?

   if len(delimiter) > 1:
   delimiter = delimiter.split(delimiter[0])[1]

Not exactly a bulletproof solution, but it's a pretty low cost fix to the issue.

Thoughts from the core team?

[ansible-project] -m setup -a filter="ansible_eth0.ipv4.address" returns no results

[Timothy Appnel]

One of the notes in the docs of the setup module reads: "the filter option 
filters only the first level subkey below ansible_facts." So you don't. Not 
that way at least. 

What about ansible_all_ipv4_addresses?

Re: [ansible-project] Spawning background processes that are not services

[Timothy Appnel]

So a few things here.

Having just breezed over what WebLogic Node Runner does, I see where something 
like service or supervisor is somewhat redundent for you. That wasn't clear to 
me from from this thread until I did that though. That's not the norm for most 
though and you weren't clear on that so I don't think its fair to say Brian is 
missing the point.

So I think I get what you are trying to do. 

We've been in a similar spot here with long running processes rather than 
daemons, but I think what we did applies here. Use the the wait_for directive 
right after your shell nohup async task and look for a sign that the 
initialization of the previous task has reached a ready state. What is "ready" 
will depend on you. In our case it's a specific line in a log file. 

Not ideal or elegant, but it should work.

Now, based on what I read, it sounds like the elegant solution would be to 
create a noderunner module where you can better manage and control the jobs 
abstracted from your playbook or role.

Hope that helps.

[ansible-project] 127.0.0.1 and localhost in synchronize module

[Timothy Appnel]

Given the nature of rsync and what it does, your question can be read a few 
ways but let me guess at what you are getting at. 

127.0.0.1 and localhost are treated specially because you're already on that 
box so you don't need to provide all of the SSH credentials. You can do a sync 
that doesn't go out to the network at all.

[ansible-project] synchronize module update request

[Timothy Appnel]

Sounds about right to me. I don't recall forcing the compress option when I 
initially wrote that module and submitted it to core. Maybe I did. Not sure why 
now tho. 

Regardless. Have you created a PR for this yet? My only suggestion is that 
compression is on by default but a user can disable it by default with a 
--no-compress flag. The behavior everyone is accustomed to continues as it's 
been but users like yourself have the means to turn that off.

Re: [ansible-project] Helper library for modules written in PHP?

[Timothy Appnel]

I've absolutely read over this thread and the project page. You've ported the 
ansible module helpers to PHP so you can write your modules in PHP rather than 
learn some Python and use what's already there.

Re: [ansible-project] Helper library for modules written in PHP?

Seems like a whole lot of trouble to avoid learning python. I don't see why 
this is any better or really necessary otherwise.

Re: [ansible-project] List of Ansible default variables

[Timothy Appnel]

What you are describing sounds a lot like what I have at my day job -- hundreds 
of instances of dozens of Java applications each with their own properties like 
unique ports, file paths and whatnot.

We addressed the things you are talking about by treating each app as a host 
regardless of physical server and from there used host and groups vars, not 
roles for what you are trying to do. Essentially roles start with tasks and 
sometimes specialized modules. The variables and defaults are there to support 
those tasks. Recently I created a module that reads the properties file all of 
these application use for their configuration and imports them as facts so 
later roles and playbooks can remain in sync with little to no effort.  

We did toy with something like your approach of wrapping application specific 
meta data as roles, but found that was messy and hard to manage. (Roles get 
checked in and treated like code, inventory not so much.) 

So based on my experience I think your struggles are a modeling problem like 
Michael suggested.

Re: [ansible-project] Jinja2 extract single value for key/value pair without looping

[Timothy Appnel]

Theoretically in Jinja 2.8 when it's released you could perform this operation 
with something like this:

{{ 
fusemq_auth|selectattr('username','equalto','LOGSTASH')|map(attribute='password')|first
 }}

selectattr and map are new to version 2.7. The 'equalto' test is the problem 
you'll run in to. 

So the map function with an optional selectattr provides the dict_to_list 
function you are looking for. (Your gist wouldn't load.) I don't see how a 
general purpose list_to_dict would be possible without some specific logic be 
written.

Re: [ansible-project] for loop in template how do I avoid trailing comma on last iteration?

[Timothy Appnel]

OK try this...

"tcp://{{ groups['fusemq']|join(',tcp://') }}"

Not exactly pretty but better than a for loop with conditionals.

Re: [ansible-project] Having problems with --exclude, --include with synchronize module using rsync_opts

[Timothy Appnel]

I found what the problem is though I don't know what the right solution is. 

https://github.com/ansible/ansible/pull/7820

Essentially safe shell module causes wildcards to be treated as literals 
with rsync. As long as that is the case you can't use wildcards with sync 
module, but you can't do that either as stated in the pull request comments 
so I'm at a bit of a loss how to resolve this issue.

[ansible-project] Having problems with --exclude, --include with synchronize module using rsync_opts

[Timothy Appnel]

We are also having some problems at the day job with wild cards and the 
synchronize module however ours is tied to the src argument. 

htttps://github.com/ansible/ansible/issues/7728

I've been looking when I have a chance but haven't figured out what's going 
wrong. I just know the command Ansible is reporting it runs works fine on the 
command line. Remove the wildcard and Ansible runs. Put it back in and it 
fails.
