PSA: Docker 17.05.0-0348 on Synology breaks Homebridge

Third party integrations Homebridge

Just an FYI and heads up for anyone (like me) that is running HA and HB via docker, the latest release of DSM (6.1.4-15217) and Docker for DSM (17.05.0-0348) break HB. I tested multiple HB and HA docker containers trying to find a good combination, but it wasn’t until I downgraded my Synology DSM to 6.1.3-15152 Update 8 and installed Docker 1.11.2-0329 from the Package Center that things started working again. The error I was receiving in the log for HB was repeated attempts to setup the avahi service (another name for the Bonjour File Service). My Synology serves up a Time Machine destination using Bonjour and having it enabled broke HB due to the service already running on the host networking service.

I don’t know yet which one breaks HB, but I’ll find out soon as downgrading DSM has presented a separate unique issue and is probably why Synology does not recommend downgrading.

EDIT: For reference, I am using the official HA docker container and the HB docker container released by oznu found here and on GitHub.

I re-upgraded to DSM 6.1.4-15217 and kept Docker at 1.11.2-0329 and everything still works. HB can see my HA devices as per my config.json file. I’m not brave enough to upgrade my Docker package yet as I don’t want to break it again. In doing some research it looks like the way containers interact with the host network (command line --net=host) has changed and that’s why it broke.

Synology has since pulled the latest Docker version 17.05.0-0344 and 17.05.0-0348.

Had the same problem. After I reinstalled the docker application (version 1.11.2-0329 after reinstall) everything worked again.
