Running in Docker

This app can run as a Docker Container on Raspbian.

If using this method you should not install Lirc on the host, instead you need to setup lirc-rpi in your /boot/config.txt file like this:

dtoverlay=lirc-rpi,gpio_in_pin=23,gpio_out_pin=22

docker run \
  --net=host \
  --cap-add SYS_RAWIO \
  --device /dev/mem:/dev/mem \
  --device /dev/lirc0:/dev/lirc0 \
  -v </path/to/config>:/app/persist \
  oznu/rpi-daikin-ir-controller

Parameters

The parameters are split into two halves, separated by a colon, the left hand side representing the host and the right the container side.

• --net=host - Shares host networking with container, required.
• -v /app/persist - The config and persistent data location.
• --cap-add SYS_RAWIO - Allows the container to talk to the GPIO pins, required.
• --device /dev/mem:/dev/mem - Share the /dev/mem device to the container, required if using temperature/humidity sensors.
• --device /dev/lirc0:/dev/lirc0 - Share the lirc device to the container, required.

Using Docker Compose

If you prefer to use Docker Compose:

version: '2'
services:
  ir-ctrl:
    image: oznu/rpi-daikin-ir-controller
    restart: always
    network_mode: host
    devices:
      - "/dev/mem:/dev/mem"
      - "/dev/lirc0:/dev/lirc0"
    cap_add:
      - SYS_RAWIO
    volumes:
      - "./persist:/app/persist"
