Ansible playbook - environment variables - ansible

Question

I am trying (newbie) to setup a playbook, which will use lookup plugin to fetch secrets from vault (https://github.com/jhaals/ansible-vault), but it will fail on missing environment variables every time. Can anyone help? Thanks for the help.
PS: token is for a test purposes
There is condition in lookup module :
url = os.getenv('VAULT_ADDR')
if not url:
raise AnsibleError('VAULT_ADDR environment variable is missing')
Playbook:
---
- hosts: localhost
vars:
vault1_env:
VAULT_ADDR: https://localhost:8200/
VAULT_TOKEN: my-token-id
VAULT_SKIP_VERIFY: True
tasks:
- shell: echo VAULT_ADDR is $VAULT_ADDR, VAULT_TOKEN is $VAULT_TOKEN, VAULT_SKIP_VERIFY is $VAULT_SKIP_VERIFY
environment: "{{ vault1_env }}"
register: shellout
- debug: var=shellout
- debug: msg="{{ lookup('vault', 'secret/hello', 'value') }}"
output:

Answer 1

Here you are only setting environmental variables for the shell module, and not for the others. If you want to use variables across multiple modules, or for an entire a host, you should use the environment attribute on all of the modules, or on the host itself, something like this:
---
- hosts: localhost
environment:
VAULT_ADDR: https://localhost:8200/
VAULT_TOKEN: my-token-id
VAULT_SKIP_VERIFY: True

Answer 2

Why don't you make use of the vault feature to encrypt a variable file and then include this file in your playbook.
