'Pass parameter from .sh file to .yml file?

I am new to Ansible as well as Ubuntu system also. I want to pass the multiple variables from .sh file to .yml. I have plan to store all input variables in an array then passing the variable one by one using for loop while calling the file distributed-setup.yml.

Currently, I am trying to pass a variable.For that,I am following the below steps.

  1. While executing the First.sh file I am passing the a variables like First.sh Input.yaml

  2. First.sh file is like this

    echo $1
ansible-playbook distributed-setup.yml --extra-vars="v:$1" -${1:-v} | tee output.txt

  3. Distributed-setup.yml

    ---
- name: Executing slaves
  hosts: slave
  gather_facts: no
  vars:
      v: "{{lookup('env','v') }}"
      contents: "{{ lookup('file','/home/ubuntu/Ansible-setup/Distributed-Ubuntu-Setup/Input/Input.yaml') | from_yaml }}"
      log: "{{ contents['log'][0] }}"
      timeout: "{{ contents['ansible-timeout'][0] }}"

In the line, contents: I need to use variable 'v' instead of Input.yaml.

How to do this?

Solution 1:[1]

One of the easiest ways to do this is through the environment

someVar=value ansible-playbook ...

and then, inside your Ansible code, you can refer to ansible_env.someVar. You can also export the variable and not need to define it on the same line.

To make this a bit more concrete for your use case:

input_yaml=/home/ubuntu/Ansible-setup/Distributed-Ubuntu-Setup/Input/Input.yaml
export input_yaml
ansible-playbook distributed-setup.yml

...and in your Ansible file:

contents: "{{ lookup('file', ansible_env.input_yaml) | from_yaml }}"

This is how you could use your variable v within other ones:

---
- hosts: localhost
  connection: local
  gather_facts: no
  vars:
    v: "{{ lookup('env','v') }}"
    b: "{{ lookup('file','/tmp/{{ v }}') | from_yaml }}"

  tasks:
  - name: set contents
    set_fact:
      contents: "{{ lookup('file','/tmp/{{ v }}') | from_yaml }}"

  - name: debug
    debug:
      msg: "{{ b }} == {{ contents }}"
    when: b == contents

v will get the value of the existing environment var v and then use it on var b later in a task just in case is created another variable named contents with the value of b in this case using set_fact

For testing do:

$ export v=foo
$ date > /tmp/foo
$ ansible-playbook test.yml

It will set v to foo then will create a file in /tmp/foo with the current date (output of the date command)
