Fioctl

This section assumes you have followed Getting started to its completion. The aim of this section is to provide you with a template for using Fioctl by way of example.

Enabling/Disabling Apps

By default all apps defined in containers.git for any given tag are enabled. To change this behaviour, a whitelist of apps can be given per device, enabling only those apps that are in a comma separated list.

Via Fioctl

fioctl devices config updates <device_name> --apps <app_name1>,<app_name2>
Set the app(s) a device will run.

Demonstration

Via lmp-device-register

When registering a device, lmp-device-register can set a list of apps to enable.

lmp-device-register --api-token=<token> --apps <app_name1>,<app_name2>
Set the app(s) a device will run, during registration.

Inspecting Targets

A Factory produces Targets whenever a change is pushed to the Factory Source Code. A Target is a description of the software a device should run, as defined by a list of metadata which includes an OSTree Hash and one or more Docker-Compose App URIs.

This metadata is recorded upon Target creation, making the Target an immutable description of the Factory at a point in time.

Fioctl provides many methods of viewing Target metadata, which can reveal:

  • What apps are available inside the Target.
  • What tag a Target has.
  • What MACHINE a Target has been produced for (HARDWARE ID).
  • What git commits caused the Target to be produced.

Target metadata can be inspected by using 3 primary commands

fioctl targets list

Lists the Targets a Factory has produced so far.

$ fioctl targets list

3        devel   simple-app,netdata,mosquitto     raspberrypi3-64
fioctl targets list -r

Lists the Targets a Factory has produced in -r (raw) json format. This is often piped into jq in order to format the json neatly.

The command output below has highlighted the docker_compose_apps section, which contains the names of apps that are available in this Target, as well as their Docker-Compose App URIs.

Additionally, the OSTree Hash for the Target has been highlighted.

Common Commands

View Targets
fioctl targets list -f <factory>
Lists the Targets a Factory has produced so far.
List devices
fioctl devices list -f <factory>
Lists the devices that have connected to a Factory, along with associated metadata, such as device name, status, Target and enabled apps.
Set device tag
fioctl devices config updates <device_name> --tags <tag>
Filter the Targets a device will accept by tag. For example, to move a device from accepting ‘devel’ builds to ‘master’ builds. See the Advanced Tagging section for more examples.
Set app(s) to be enabled
fioctl devices config updates <device_name> --apps <app_name1>,<app_name2>
Set the app(s) a device will run.
Enable WireGuard VPN
fioctl devices config wireguard <device_name> <enable|disable>
Enable or disable the Wireguard systemd service on a LmP device. This requires that you configure a Factory to use an instance of Wireguard you have set up on your own server as described in the WireGuard VPN guide.
