Re: [ansible-project] delegate_to /one member/ of a group

[Elliott Barrere]

Okay, just getting back to this.  I have this in my site.yaml file in 
group_vars:

rwdc_server: '{{groups.rwdcs|random}}'


but it appears that the rwdc_server variable gets a different domain 
controller from the group each time it's accessed (sometimes it's the same 
one, but not always).  I need the value to be consistent so I can run a 
series of commands on the same box.  Is this possible?

I'd rather not pin it to a single box (with e.g. {{groups.rwdcs[0]}}), for 
basic load balancing & HA...

Hi all,

I'm very new to ansible and sorry if the question is too easy


I have defined host_var

And I want to append values to it from a task

- set_fact: locked_domains="{{ locked_domains + item.ID }}"
  when: {{item.state}} == "some_cond"
  with_items: "{{ domains.json }}"


where domains.json is an array of objects

I get the following error

fatal: [localhost] => Failed to template locked_domains="{{ locked_domains 
+ item.ID }}": an unexpected type error occurred. Error was unsupported 
operand type(s) for +: 'NoneType' and 'str'

FATAL: all hosts have already failed -- aborting

Please advise

Thanks

[ansible-project] Copying a remote MySQL Database

[Steven Parsons]

I am wondering if anyone has copied a MySQL database from a location and 
then restored it locally using Ansible? I thought I had it figured out with 
the following syntax, but for some reason its failing.

- name: Install python-mysqldb
  apt: name=python-mysqldb state=latest

- name: Copy MySQL Database
  mysql_db: login_host=onthe.web.net login_user=someone login_password=cheese 
state=dump name=cheese target=/tmp/cheese.sql
  mysql_db: state=import name=cheese target=/tmp/cheese.sql

Any help would be appreciated.

Re: [ansible-project] Module Parameter Defaults (or Module Shortcut/Alias) ?

[Matt Martz]

This is technically feasible now, but it isn't specifically ansible
functionality, instead it is YAML functionality.  Here is an example
playbook that displays how this works:

---
- hosts: all
  gather_facts: false
  vars:
- uri_defaults: &URI_DEFAULTS
url: "http://httpbin.org/get";
method: GET
  tasks:
- uri:
<< : *URI_DEFAULTS
status_code: 200

- uri:
<< : *URI_DEFAULTS
status_code: 201
  ignore_errors: true

- uri:
<< : *URI_DEFAULTS
url: "http://httpbin.org/status/201";
status_code: 201


This uses YAML aliases, anchors, and merge functionality.

[ansible-project] Re: Setup facts: ansible_default_ipv4 is empty, even when interface is active with an ip address

[Joanna Delaporte]

This might just be a configuration issue with my host. I'm still working on 
bootstrapping it to be my new control host.  I also just realized that AWS 
EC2 hosts give their internal addresses, not public, so default ipv4 won't 
always do what I need.

My goal is to fetch a set of ssh public_key files gathered from remote 
hosts, and name them with user + the hosts' public ip addresses.  Is there 
a way to extract the ips from a group of hosts? I am ending up with one 
file rather than a file for each host when I use the following:

My task:

- name: copy new keys back to repo
fetch: "src=/home/ansible/.ssh/id_rsa.pub
dest=/home/ansible/public_keys/ansible_{{item}}
flat=yes"
with_items:
- '{{ hosts }}'

On the command line I specify --extra-vars "hosts=ipaservers" and end up 
with one file named ansible_ipaservers with only one key in it. I'm hoping 
to end up with something like ansible_52.x.x.x, ansible_192.x.x.x, 
ansible_176.x.x.x files instead, each with the ansible user's key on that 
host.

[ansible-project] Help with callback to tower from AWS auto scaling script

[Adrian Black]

Trying to put the bits together to get an auto scaling group in aws to come 
on line and create a vm that does a callback to tower for provisionment.

The bit im getting stuck with is the callback part

According 
to http://docs.ansible.com/ansible-tower/2.2.0/html/userguide/job_templates.html

you use the /usr/share/awx/request_tower_configuration.sh script as a basis

this script looks like it takes arguments so should be called somethig like 

./scripts/request_tower_configuration.sh  ansible.myco.com 
84e2d9d26c5977c1b12eb353f1a97aa1 94

I have seen the launch config script snippet like

- name: create launch config
 ec2_lc:
   name: "{{ site_prefix }}-lc"
...
   user_data: "{{ lookup('file', 
'./scripts/request_tower_configuration.sh')}}"

that takes the contents of that file as pastes it as a blob in the 
user_data field on a created vm but without the arguments you need its 
useless.

i did try this too but that doesnt work
user_data: "{{ lookup('file', './scripts/site_callback.sh') 
 ansible.idg.co.uk 84e2d9d26c5977c1b12eb353f1a97aa1 94 }}"


anyone got a working example of how this works?

thanks

Hi Paul,

my suggestion is that you practice in a test environment such as a
VirtualBox VM as you told. Otherwise, using Vagrant is a good choice
as well (see [1]).

You may have a look to Ansible Examples [0] and let the magic happens,
and then try to adapt those examples to your needs.

Internet is plenty of Ansible manuals, so you could start with a basic
"ansible -m ping localhost" style manual [1] and then become a ninja
like OpenShift guys [2].

Hope it helps!

[ansible-project] Problem with function to merge nested dictionaries

[Max Lock]

Hi All,

 I'm using ansible 1.9.3, and want to merge two nested dicts to template to 
a config file. I've written a combine function similar to whats in 2.n.n. 
The problem is that the merged dictionary appears to be unicode preventing 
me from iterating over it in the template. This is the combine function:

def combine(original, update):
for key, value in original.items():
if not key in update:
update[key] = value
elif isinstance(value, dict):
combine(value, update[key])

return update

class FilterModule(object):

def filters(self):
return {
'combine': combine,
}

My testcase is this.

---
- hosts: all
  gather_facts: False
  vars:
a:
  first:
second: 'foo'
b:
  first:
third: 'bar'

  tasks:
- set_fact: c="{{ a | combine(b) }}"
- debug: var=c
- debug: msg="{% print a.__class__ %}"
- debug: msg="{% print b.__class__ %}"
- debug: msg="{% print c.__class__ %}"...

Which when run produces:

PLAY [all] 


TASK: [set_fact c="{{ a | combine(b) }}"] 
*
ok: [localhost]

TASK: [debug var=c] 
***
ok: [localhost] => {
"var": {
"c": {
"first": {
"second": "foo",
"third": "bar"
}
}
}
}

TASK: [debug msg=""] 
**
ok: [localhost] => {
"msg": ""
}

TASK: [debug msg=""] 
**
ok: [localhost] => {
"msg": ""
}

TASK: [debug msg=""] 
**
ok: [localhost] => {
"msg": ""
}

PLAY RECAP 

localhost  : ok=5changed=0unreachable=0failed=0


Notice that both parent dicts are of type dict, but the merged child is of 
type unicode? Any help much appreciated. :)

 -Cheers Max.

[ansible-project] New to Ansible - how to setup a practice environment

[Paul Davies]

Hi all

I am new to Linux, Ansible and CI/Devops in general having come from a 
Windows/SQL background


I am trying to learn Ansible, My requirements are to control it from a 
CentOS machine and control other CentOS/Solaris machines and possibly 
Win2008R2 too


on my Windows desktop, I have created a CentOS VirtualBox and installed 
Ansible via yum. I have no other remote machines to use as yet


My question is simply - how do you practice? Am I best creating other 
VirtualBox machines on the same host and trying to control those, or am I 
best creating other VMs on my CentOS VM and controlling those? If the 
latter - then am I best using VirtualBox again or Vagrant (new to that too) 
to create the target VMs?

Or am I best doing something completely different?

Any advise welcome!

thanks
Paul

[ansible-project] Unstable network

[karljohanreite]

Hi,

We are facing a situation where we have servers with slow and unstable 
network connections. This is because the network is provided by GSM modems 
onboard moving vessels.

Does anyone know how Ansible will handle a situation where the network may 
fall out during deployment? Will the deployment happen in a somewhat atomic 
way, or will the deployment be abruptly aborted if the ssh channel 
terminates?

I appreciate any insights or suggestions on this.

Thank you.

[ansible-project] Using ansible inside docker

[lewis]

Does anyone use ansible inside docker? We have for a while now, and we've 
had nothing but trouble with ansible's service module and docker's 
inability to run upstart.

Ansible 1.9 onwards seems to prefer using initctl over service, which in 
Docker is symlinked to /bin/true and so fails silently. Whereas service 
works fine, since it will default to sysv scripts if upstart isn't 
available. Is there a specific reason that ansible prefers initctl? 

Is it worth putting in a PR to detect this use-case specifically (initctl 
being symlinked to bin/true)? Or would a better fix be to let the user 
explicitly define a service module somehow?

Re: [ansible-project] Spaces in URL and file name with get_url and unarchive

[Nathan Sowatskey]

Toshio

This is very helpful, thank you very much.

My vote is for is an option that turns it on explicitly.

My reasoning is as follows:

 - That would obviate the need to change variable values explicitly, which may 
anyway not be possible if the variable value is external and not under the 
control or definition of the playbook, e.g. an environment variable or a 
variable generated by another system at runtime.
 - It would support “intelligent” behaviour, and it is reasonable to expect 
tools such as Ansible to be intelligent and do such things for you.
 - I find the current behaviour and the lack of an option surprising, 
obviously, so there is an element of failing to pass the test of “least 
surprise”.
