Ansible user issue

gistfile1.md

Setup

1. Passwords, not keys are used for ssh
2. The target is accessed via the bastion host (ssh -> bastion -> target)
3. The password is kept in an encrypted file that is accessed based on the ansible_user name
4. When decrypted, the password is bastion

Command

$ ansible -i ./inventory/debug -m debug -a 'var=foo' -kKu ansible all

Command Output

target | FAILED! => {
    "msg": "The field 'ssh_common_args' has an invalid value, which includes an undefined variable. The error was: 'ansible_user' is undefined"
}
bastion | SUCCESS => {
    "foo": "-o ProxyCommand=\"sshpass -p bastion ssh -o StrictHostKeyChecking=no -W %h:%p -q ansible@3.21.247.xxx.\""
}

Problem

1. The password is correctly accessed and resolved for foo for bastion, but foo cannot be resolved for the target host.

The inventory file (called "debug")

all:
  vars:
    env: 3.21.247.xxx
    password: "{{lookup('file', inventory_dir + '/../users/' + ansible_user + '.yml')}}"
    foo: "-o ProxyCommand=\"sshpass -p {{password}} ssh -o StrictHostKeyChecking=no -W %h:%p -q ansible@{{env}}.\""

    bastions:
      hosts:

          ansible_host: "{{ env }}"

               ansible_host:  10.0.3.209
           vars:
              ansible_ssh_common_args: "{{ foo }}"
