Another thing you might consider is using a YAML reference to duplicate
the environment in a regular playbook variable. Then you can use plain
old variable references to see those values. See the example below:
*[utoddl@tango ansible]$ cat ygkumar1.yml *
---
# Playbook ygkumar1.yml
- name: Copy environment to testable variables using YAML reference
hosts: localhost
gather_facts: false
*environment: &environment script_var1: hi script_var2: there*
vars:
pb_dict:
not_env_var1: foo
not_env_var2: bar
*env_vars: *environment*
other_stuff: bas
tasks:
- name: Dump pb_dict to the job log
ansible.builtin.debug:
var: pb_dict
- name: Shell script to loop over pb_dict.env_vars
changed_when: false
ansible.builtin.shell: |
for vname in {{ pb_dict.env_vars.keys() | map('quote') | join(' ') }} ;
do
printf -- "Environment variable %s: %s\n" "$vname" "$(eval echo
\${$vname} )"
done
*[utoddl@tango ansible]$ ansible-playbook ygkumar1.yml -vv*

Hi All,
I am declaring an environment variables in a playbook as shown below:
--
---
- hosts: localhost
environment:
script_var1: hi
script_var2: there
tasks:
- name: List
shell: bash test.sh
--
I want to test the existence of the above environment variables in a
separate task.yml file. How do I test their existence ? What is the
syntax ?
