build-airconnect

This is a simple and small docker container for AirConnect.

The repo points to uses a Docker image maintened by linuxserver.io image, which insists on running as root and then runs a whole init system for some reason.

This image just uses the precompiled binaries that are in a .zip file in the AirConnect repo (see the Dockerfile), it doesn't build AirConnect.

Running

Since we don't want to run an init system in a docker container and AirConnect has separate binaries for UPnP and Chromecast, just run two containers:

For airupnp (UPnP/Sonos):

# pass cmdline args:
docker run --name airconnect-airupnp -it --net=host \
    git.sudo.is/ben/airconnect airupnp -Z -l 1000:2000

# if you want to mount an /etc/airupnp.xml config file instead:
docker run --name airconnect-airupnp -it --net=host \
    -v airupnp.xml:/etc/airupnp.xml \
    git.sudo.is/ben/airconnect airupnp

Here the -Z argument is importabt, it instructs airconnect to not listen to input on stdin. Otherwise it will loop indefinitely and use 100% cpu.

For aircast (Chromecast):

docker run --name airconnect-aircast -it --net=host \
    git.sudo.is/ben/airconnect aircast

You can also set the environment vars ${AIRCONNECT_PROG} and ${AIRCONNECT_ARGS} respectively instead. this is for example useful in ansible playbooks using docker_container tasks:

- name: "start airconnect containers"
  docker_container:
    name: airconnect-{{ item }}
    hostname: airconnect-{{ item }}
    image: git.sudo.is/ben/airconnect
    detach: true
    pull: true
    auto_remove: false
    restart_policy: "unless-stopped"
    state: "started"
    network_mode: host
    env:
      AIRCONNECT_PROG: "{{ item }}"
  loop_control:
    label: airconnect-{{ item }}
  with_items:
    - airupnp
    - aircast
