Because this container is attached to the bridge network on a private subnet, a port on the host system like 8000 needs to be mapped to port 80 on the container for outside traffic to reach the web service. As an example, consider you can have a Docker container running a web service on port 80. Bridge networks are easy to create, manage and troubleshoot.įor the containers on bridge network to communicate or be reachable from the outside world, port mapping needs to be configured. It is limited to containers within a single host running the Docker engine. Bridge Networksīridge networking is the most common network type. The most common network types being: bridge, overlay, and macvlan.
DOCKER NETWORK TROUBLESHOOTING DRIVERS
See Docker Documentation: Default Networks › Docker Network Typesĭocker comes with network drivers geared towards different use cases. Each new Docker container is automatically attached to this network, unless a custom network is specified.īesides docker0, two other networks get created automatically by Docker: host (no isolation between host and containers on this network, to the outside world they are on the same network) and none (attached containers run on container-specific network stack). When Docker is installed, a default bridge network named docker0 is created. See Docker Documentation: Network Containers › Docker Default Networking (docker0) Additionally, clients from the outside world will need to access the web application container. Docker supports different types of networks, each fit for certain use cases.įor example, building an application which runs on a single Docker container will have a different network setup as compared to a web application with a cluster with database, application and load balancers which span multiple containers that need to communicate with each other.

The sonos never “speaks” the tts, after much testing I can only assume its something to do with the traefik setup - but I have the traefik.toml backend setup as you described…only difference being there is no docker-compose entry as it runs on a different pc which runs hassio docker on ubuntu server. I have various sonos speakers, but have focused on trying to send tts to a sonos beam, the difference in my setup is I have two pc’s - 1 running docker with traefik & the other running home assistant - both on the same network and using the traefik backend to send data.

=15552000Īnd the relevant parts of my traefik.toml file: var/homeserver/traefik/.htpasswd:/.htpasswdĪnd for home assistant, I use this (snippet from my docker-compose file): network_mode: host var/homeserver/traefik/acme.json:/acme.json var/homeserver/traefik/traefik.toml:/traefik.toml var/run/docker.sock:/var/run/docker.sock Here’s my docker-compose for Traefik: version: '3' I run with both Traefik and Home Assistant in host network mode.

I am not sure how to debug this, anybody have a guess where I am screwing things up? I notice in the first setup, the home assistant backend has an IP address in the docker network range, and in the host network mode, the backend has IP 127.0.0.1, all seems ok, but it won’t route correctly.

But traefik no longer seems to be able to connect frontend to backend.

When I remove the networks: part and replace it with “network_mode: host”, auto-discovery works, and it finds all devices on my network. Image: homeassistant/home-assistant:latest

But, auto-discovery does not work in HA, nor can it find chromecast or sonos devices I have in my house. When I configure HA in docker-compose with the networks: option, to make it part of the traefik_proxy network I have setup, I can access HA on the specified domain. Additionally, I am using Traefik as a reverse proxy, which is where I run into issues. I am running HA (not hassio) on an intel Nuc using docker, with some additional stuff like influxdb, grafana and nodered.
