10 months ago Hi @u6bkep
This is a bug caused by presence of second network configuration for you container which isn't well-supported in the version from master branch.
As a workaround you may add a label coredns.dockerdiscovery.network to the compose config of your container, i.e.:
jellyfin:
container_name: jellyfin
privileged: true
image: jellyfin/jellyfin:10.8.10
restart: unless-stopped
volumes:
- jellyfin_config:/config
- jellyfin_cache:/cache
- /media:/media
networks:
lan:
ipv4_address: "10.2.4.103"
ipv6_address: "fdb7:1860:52b3:8103::103"
aliases:
- "jellyfin.b.intern.gecko.network"
default:
hostname: jellyfin
labels:
coredns.dockerdiscovery.network: "lan"This will likely cause this container to become resolvable by it's name but with it's IP's from lan network.
u6bkep
dockerdiscovery fails to get ip addresses of containers if it has statically assigned ip addresses. container jellyfin is attached to custom docker network docker1 with statically assigned addresses 10.2.4.103 and fdb7:1860:52b3:8103::103. failes with log error
