I have a docker-compose project that I would like to convert to Ansible.

Everything is working fine but I want to convert the command below from docker compose to Ansible.
I tried to pass (env, envfile command) and it is still not working correctly. This is the command in docker compose

 Environment:
 - NGINX_HOST=http://nginx:80

Is there any way to select and use environment variables in Ansible playbook?
What is the syntax of this command in Ansible ?

  For the enviroment variables of target machine, use lookup('env', 'NGINX_HOST') . For the ones of source, see this post: stackoverflow.com/questions/21422158/…

if you use variable from vars. You can use syntax like this "repo", also key for environment variables is env, not Environment.

- hosts: fix
 remote_user: root
 vars:
 repo: test
 tasks:
 - name: prom
 docker_container
 env:
 REPO: "repo"
 HOSTIP: " ansible_eth0.ipv4.address "
 NGINX_HOST: http://nginx:80
