Configure wpa_cli by config_light

To configure the image, we'll use Ansible role vbotka.config_light, instead of the :ref:`ug_tasks`. This example, using config_light, configures exactly the same parameters of the wireless network as the role vbotka.freebsd_wpa_cli. Review the goal of Ansible role FreeBSD wpa_cli and read at least the Introduction. The purpose of using the role config_light, instead of freebsd_wpa_cli, is building single source of the configuration in the directory cl_dird.

The playbook pb-wifi-basic.yml created in the :ref:`qg` will be used to attach a memory disk and mount the partition.

  • Current directory reuses the data from the previous example

    shell> ls -1
conf-light
files
hosts
pb-wpacli-cl.yml
pb-wifi-basic.yml

  • Install the role vbotka.config_light

    shell> ansible-galaxy install vbotka.freebsd_config_light

  • Create the playbook pb-wpacli-cl.yml for single host images.example.com (1). Configure connection (3-4) and privilege escalation (5-7). Configure the directory (12) with the configuration files and reuse the configuration (14-17) already prepared in :ref:`qg` (28-55). Configure only wlan0 (18) in wpa_supplicant. The configuration of wpa_cli (58-78) is described in Ansible role vbotka.freebsd_wpa_cli. The configuration of ntp (81-94) is described in Ansible role vbotka.freebsd_postinstall.

  • Create the configuration files in the directory cl_dird

    shell> tree conf-light/

  • Create the directory wiht the patches

    shell> tree files/

  • Create the inventory. Change the IP adress (2) and fit the paths to Python (8) and Perl (9) if necessary
 shell> cat hosts
 images.example.com ansible_host=<ip-address>

 [images]
 images.example.com

 [images:vars]
 ansible_python_interpreter=/usr/local/bin/python3.7
 ansible_perl_interpreter=/usr/local/bin/perl

  • Mount the image using the playbook prepared in :ref:`qg`

    shell> ansible-playbook pb-wifi-basic.yml -t bsd_cimage_mount

  • Test syntax

    shell> ansible-playbook pb-wpacli-cl.yml --syntax-check

  • See what variables will be included

    shell> ansible-playbook pb-wpacli-cl.yml -t cl_debug -e cl_debug=true

  • Run the playbook

    shell> ansible-playbook pb-wpacli-cl.yml

  • Umount the partition and detach the memory disk

    shell> ansible-playbook pb-wifi-basic.yml -t bsd_cimage_umount

  • Write the customized image to a disk and boot the system. Connect to the system and review the log. For example

    shell> cat /tmp/wpa_action.wlan0
