I am iterating over yml file and filtering and keeping those microservice metadata in the list which is in the command line argument passed
ansible-playbook -i inventory/inventory sp-deployer.yml --ask-vault-pass --extra-vars '{"microservices_list":[iwan,csrservice]}'
Finally I need these three value from the yml file based on the criteria mentioned above. I have created ansible sp-deployer.yml for this purpose. I have used set_facts for creating dynamic list. First list works fine but the moment I create second one it fails.

Friendly advice: always check registered variables with debug if you bump on such errors.
The reason for your error is that set_fact don't yield ansible_facts dict if the loop iteration is skipped.
And I see you have when statement in your loop.
To overcome this error, you should select only those loop iterations, that have ansible_facts dict defined:
- name: make a list
set_fact: foo1="{{ result_final.results | selectattr('ansible_facts','defined') | map(attribute='ansible_facts.foo_item1') | list }}"

I have playbook as below:
- name: fetch host group name
set_fact:
group_name: '{{ group_names[0] }}'
- name: get memory and storage minimum requirements
set_fact:
min_memory: "{{ group_name.memory }}"
min_storage: "{{ group_name.storage }}"
In defaults/main.yml
#memory and storage settings
primary:
memory: 32
storage: 128
my inventory host is in primary group.
when I run playbook, I am seeing below error.
TASK [ansible-elastic-cloud-enterprise : get memory and storage minimum requirements] ****************************************************************************************************************************
fatal: [192.168.153.5]: FAILED! => {"msg": "The task includes an option with an undefined variable.

you want to use the content of variable like another variable, so use lookup vars:
sample:
- name: dynamic var
hosts: localhost
gather_facts: no
vars:
groupname: ["primary", "secondary"]
primary:
memory: 32
storage: 128
tasks:
- set_fact:
id: "{{ lookup('vars', groupname[0]) }}"
- debug: msg="{{ id.memory }} -- {{ id.storage }} "
result:
ok: [localhost] => {
"msg": "32 -- 128 "
in your case you should write:
- name: fetch host group name
set_fact:
group_name: '{{ lookup("vars", group_names[0] }}'
The goal is to read the input file for a string that matches the regex expression then to match the expression to my config file.. when there is a match ansible is to replace the existing line in the config file with the matching line in the delta file.
I was able to perform this task but noticed that ansible would read one line and essentially be done. I added the .splitlines() option to my code so that it would read line by line and perform the same action but i received the following error:
- name: Search for multiple reg expressions and replace in config file
vars:
# pull data from config file
input: "{{ lookup('file', '{{ record }}').splitlines() }}"
delta: "{{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*?', multiline=True )}}"
delta1: "{{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*', multiline=True)}}"
record: "/etc/ansible/roles/file_config/files/records/records.config.{{ inventory_hostname }}"
lineinfile:
path: /dir/dir/WCRUcachedir/records.config
# Line to search/Match against
regexp: "{{item.From}}"
# Line to replace with
line: "{{item.To}}"
state: present
backup: yes
with_items:
- { From: '{{delta}}', To: '{{delta1}}' }
This happened to be my end result
"msg": "An unhandled exception occurred while templating '{{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*', multiline=True )}}'. Error was a <class 'ansible.errors.AnsibleError'>, original message: Unexpected templating type error occurred on ({{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*', multiline=True )}}): expected string or buffer"
}
these are what i believe my conflicting lines are
input: "{{ lookup('file', '{{ record }}').splitlines() }}"
AND
delta1: "{{ input | regex_search('^.[a-zA-Z]+._.[a-zA-Z]+.', multiline=True)}}"
OK, you do have another problem.
In the vars section, when you're setting delta and delta1, regex_search is expecting a string, but your passing a list (which splitlines() created). But you need it to work on one line at a time.
So, rather that input, use item, which will be set in the loop:
vars:
input: "{{ lookup('file', '{{ record }}').splitlines() }}"
delta: "{{ item | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*?')}}"
delta1: "{{ item | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*')}}"
Obviously, you don't need the multiline=True any more.
Now, the loop will look like this:
lineinfile:
path: /etc/opt/CCURcache/records.config
regexp: "{{ delta }}"
line: "{{ delta1 }}"
state: present
backup: yes
loop: "{{ input }}"
when: delta != ""
Yes, you only have one item to loop over. That item has two elements, From and To.
From is {{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*?', multiline=True )}}
To is {{ input | regex_search('^.*[a-zA-Z]+.*_.*[a-zA-Z]+.*', multiline=True)}}
All you did in the vars section was define strings, which will get executed later, when the regex and line are used in the module.
Now, assuming you need to put these together, you need to zip them:
lineinfile:
path: /etc/opt/CCURcache/records.config
regexp: "{{item.0}}"
line: "{{item.1}}"
state: present
backup: yes
loop: "{{ delta|zip(delta1)|list }}"
Here's a simple example:
---
- hosts: localhost
connection: local
gather_facts: no
vars:
list1:
- key_1
- key_2
- key_n
list2:
- value_1
- value_2
- value_n
tasks:
- name: Loop over lists
debug:
msg: "key is {{ item.0 }}; value is {{ item.1 }}"
loop: "{{ list1|zip(list2)|list }}"
And the results:
PLAY [localhost] *******************************************************************************
TASK [Loop over lists] *************************************************************************

I am new to Ansible.
I have simple ansible playbook it gets uses ec2_asg_facts and get every thing about particular AWS auto scaling group. Assume currently, I have only one Auto scaling group.
I was able get instance id, and i have run ec2_remote_facts on those id.
Problem:
Now I want to fatch private IP address of instance, I have an error that is pasted below. Please can any one help me.

You need to use with_items to access the result of the registered variable and then get the first item of "asg_instance_ids" when accessing it later:
- name: Create list of instance_ids
set_fact:
ec2_asg_instance_ids: "{{ item.instances | map(attribute='instance_id') | list }}"
with_items: "{{ ec2_asg_facts_results.results }}"
Also try debbuging the variable "ec2_asg_facts_results" to see if you actually have results in there:
- debug:
msg: "{{ ec2_asg_facts_results }}"
Looking for help with a problem I've been struggling with for a few hours. I want to iterate over a list, run a command, register the output for each command and then iterate with debug over each unique registers {{ someregister }}.stdout
For example, the following code will spit out "msg": "1" and "msg": "2"
---
- hosts: localhost
gather_facts: false
vars:
numbers:
- name: "first"
int: "1"
- name: "second"
int: "2"
tasks:
- name: Register output
command: "/bin/echo {{ item.int }}"
register: result
with_items: "{{ numbers }}"
- debug: msg={{ item.stdout }}
with_items: "{{ result.results }}"
If however, I try and capture the output of a command in a register variable that is named using with_list, I am having trouble accessing the list or the elements within it. For example, altering the code slightly to:
---
- hosts: localhost
gather_facts: false
vars:
numbers:
- name: "first"
int: "1"
- name: "second"
int: "2"
tasks:
- name: Register output
command: "/bin/echo {{ item.int }}"
register: "{{ item.name }}"
with_items: "{{ numbers }}"
- debug: var={{ item.name.stdout }}
with_items: "{{ numbers }}"
Gives me:
TASK [debug]
> ******************************************************************* fatal: [localhost]: FAILED! => {"failed": true, "msg": "'unicode
> object' has no attribute 'stdout'"}
Is it not possible to dynamically name the register the output of a command which can then be called later on in the play? I would like each iteration of the command and its subsequent register name to be accessed uniquely, e.g, given the last example I would expect there to be variables registered called "first" and "second" but there aren't.
Taking away the with_items from the debug stanza, and just explicitly defining the var or message using first.stdout returns "undefined".
Ansible version is 2.0.2.0 on Centos 7_2.
Thanks in advance.
OK so I found a post on stackoverflow that helped me better understand what is going on here and how to access the elements in result.results.
The resultant code I ended up with was:
---
- hosts: localhost
gather_facts: false
vars:
numbers:
- name: "first"
int: "1"
- name: "second"
int: "2"
tasks:
- name: Register output
command: "/bin/echo {{ item.int }}"
register: echo_out
with_items: "{{ numbers }}"
- debug: msg="item.item={{item.item.name}}, item.stdout={{item.stdout}}"
with_items: "{{ echo_out.results }}"
Which gave me the desired result:
"msg": "item.item=first, item.stdout=1"
"msg": "item.item=second, item.stdout=2"
I am not sure if I understand the question correctly, but maybe this can help:
- debug: msg="{{ item.stdout }}"
with_items: echo_out.results
Please note that Ansible will print each item and the msg both - so you need to look carefully for a line that looks like "msg": "2".
