[ansible-project] Ansible 2.13 yum module - requires minimum version of target python of 2.7 or 3.5. But I already have that
I have an Ansible (2.13) machine targeting a remote centOS 6 with Python
3.6.
Remote machine has python3.6 installed and variables are set like this:
$ ansible-inventory --host centos-6-vm
{
"ansible_private_key_file": "~/.ssh/id_rsa",
"ansible_python_interpreter": "/usr/bin/python3.6",
"ansible_user": "daniel"
}
Ansible can ping, setup and gather facts from target successfully.
But when trying to run the yum module, I get an error as if my server
doesn't have Python 3.6
This is my playbook
---
- name: Deploy Services
hosts: centos-6-vm
gather_facts: true
tasks:
- name: Show python interpreter
debug:
var: "{{ item }}"
with_items:
- ansible_python_interpreter
- ansible_python_version
- name: Patch
become: true
yum:
name: "*"
security: true
state: latest
update_cache: true
The first task is just to confirm that Ansible is recognizing Python
versions. And the result is success.
ok: [centos-6-vm] => (item=ansible_python_interpreter) => {
"ansible_loop_var": "item",
"ansible_python_interpreter": "/usr/bin/python3.6",
"item": "ansible_python_interpreter"
}
ok: [centos-6-vm] => (item=ansible_python_version) => {
"ansible_loop_var": "item",
"ansible_python_version": "3.6.6",
"item": "ansible_python_version"
}
But when it gets in the module, it gets an error saying no Python3.
TASK [Patch]
***
fatal: [centos-6-vm]: FAILED! => {"changed": false, "msg": "ansible-core

Hat 4.4.7-17)]"}
Any idea how can I approach that?

[ansible-project] 'include_vars' doesn't find the vars file
I want to include a defaults, or variable file in the /defaults/main.yml of a

Upon execution I am getting "the defaults/main.yml file for role

the pg_disable_defaults.yml works as soon I move it to ~/defaults/main.yml, so
the file itself does not appear to be the source of bad here.
Seems I am fundamentally getting something wrong here ... what is it?
Maybe the idea of a starting point in 'role_name/defaults/main.yml'?

Re: [ansible-project] Lineinfile - Skip/Update an item inside "with_items" using conditions
Thanks for your reply Vladimir Botka.
This is my actual case:
defaults > main.yml
---
# defaults file for redis_configs
redis_config_path: /etc/redis/redis.conf
# Default Params Values
MAX_MEM: 3000
TCP_KEEPALIVE: 0
TCP_BACKLOG: 511
MAX_CLIENTS: 15000
TIMEOUT: 1500
And this is:
Tasks > main.yml
---
- name: "Update Redis Parameters in {{ redis_config_path }}"
lineinfile:
path: "{{ redis_config_path }}"
backrefs: yes
regexp: "{{ item.regexp }}"
line: "{{ item.line }}"
with_items:
- { regexp: '^maxmemory', line: "maxmemory {{ MAX_MEM }}mb", when: {{
MAX_MEM }} is defined }
- { regexp: '^tcp-keepalive', line: "tcp-keepalive {{ TCP_KEEPALIVE
}}", when: {{ TCP_KEEPALIVE }} is defined }
- { regexp: '^tcp-backlog', line: "tcp-backlog {{ TCP_BACKLOG }}",
when: {{ TCP_BACKLOG }} is defined}
- { regexp: '^maxclients', line: "maxclients {{ MAX_CLIENTS }}", when:
{{ MAX_CLIENTS }} is defined}
- { regexp: '^timeout', line: "timeout {{ TIMEOUT }}" }
I want this to check if each variable inside an item is defined then make
the changes to the line in the file, otherwise skip only those items which
variables is not defined.
For Instance, If I comment out the variable MAX_MEM from the defaults >
main.yml. like below:
# Default Params Values
##MAX_MEM: 3000
TCP_KEEPALIVE: 0
TCP_BACKLOG: 511
MAX_CLIENTS: 15000
TIMEOUT: 1500
Then the execution should skip changes to the line where MAX_MEM is
undefined, and the rest lines should be changed as they defined.
Is it possible?

Set *default* to avoid errors, add attribute *def*, and select lines.
For example,
shell> cat pb.yml
---
- hosts: localhost
gather_facts: false
vars:
lines:
- regexp: '^text1'
line: 'text1 = {{ VAR1|d("undef") }}'
def: '{{ VAR1 is defined }}'
- regexp: '^text2'
line: 'text2 = {{ VAR2|d("undef") }}'
def: '{{ VAR2 is defined }}'

def: '{{ VAR3 is defined }}'
