| # Ansible doesn't expose the shell environment of the remotely logged in user | |
| # so we need to use a few tricks to get some of these values. | |
| # | |
| # This playbook demonstrates how to get a couple of useful environment variables. | |
| # | |
| # NOTE: these values are different to ansible_env.ansible_user_dir and | |
| # ansible_env.ansible_user_shell which represent the user running ansible. | |
| - hosts: all | |
| vars: | |
| app_user: foobar | |
| tasks: | |
| - name: Get the user's home directory | |
| shell: > | |
| egrep "^{{ app_user }}:" /etc/passwd | awk -F: '{ print $6 }' | |
| changed_when: false | |
| register: user_home | |
| - name: Get the user's shell | |
| shell: > | |
| egrep "^{{ app_user }}:" /etc/passwd | awk -F: '{ print $7 }' | awk -F/ '{print $3}' | |
| changed_when: false | |
| register: user_shell | |
| - debug: msg="info for user {{ app_user }} - HOME={{ user_home.stdout }}, SHELL={{ user_shell.stdout }}" | |
| # To access the user's environment variables we invoke their shell in interactive mode which presumably | |
| # will run load .profile and/or .login | |
| - name: Get the user's language | |
| command: "{{ user_shell.stdout }} -ic 'echo $LANG'" | |
| changed_when: false | |
| register: user_lang | |
| - debug: msg="language for user {{ app_user }} is {{ user_lang.stdout }}" |
