select group_var variable file in top level playbook

Question

I have defined all my variables in group_vars/all/vars_file.yml and my playbook is as below:

---
# Top level play site.yml
- hosts: webclient

  roles:
    - common
    - nginx
    - nvm
    - deploy_web_client

- hosts: appserver
  roles:
    - common
    - gradle
    - tomcat
    - deploy_sb_war

Now I have 3 environments dev / staging / production. Depending upon the environment i used to change the vars_file.yml under group_vars and then run the ansible-play.

Is there any way I can keep 3 files like "group_vars/dev" , "group_vars/staging", "group_vars/production" and specify it in my main site.yml

I have 3 inventory files as below, and depending upon the environment during ansible-play i specify the inventory file name

[webclient]
10.20.30.40

[appserver]
10.20.30.41

Friendly advice: don't use groups for environments separation, use different inventories. — Konstantin Suvorov
Yes I do have separate inventory files and use that during the ansible-play command, updated my inventory by editing the question — Naggappan Ramukannan

Instead of using inventory files saved in a single directory, use inventory files in separate directories and put group_vars inside each of them.

.
├── dev
│   ├── group_vars
│   │   └── all
│   │       └── vars_file.yml
│   └── inventory
├── production
│   ├── group_vars
│   │   └── all
│   │       └── vars_file.yml
│   └── inventory
└── staging
    ├── group_vars
    │   └── all
    │       └── vars_file.yml
    └── inventory

Then point to the directory in the ansible-playbook call:

ansible-playbook -i dev <the_rest>
