I have two container that needs to communicate with each other.
One of the containers needs to be on the host network to send&receive udp multicast packages.
How can i do this with docker compose?
I got it working when i deploy the container per hand and use the container IPs.
But thats not suitable and feels like there must be a better way.
I want that the container that has its network type set to “host”, but its still possible to resolve other docker container names like they are on the same bridge network.
version: "2" services: database: image: mongo container_name: database hostname: database ports: - "27017:27017" backend: image: "project/backend:latest" container_name: backend hostname: backend environment: - NODE_ENV=production - DATABASE_HOST=database ports: - "8080:8080" depends_on: - database tty: true connector: image: "project/connector:latest" container_name: connector hostname: connector environment: - NODE_ENV=production - BACKEND_HOST=backend depends_on: - backend # net: host network_mode: "host" tty: true
The problem with the yaml file above is, that the connector can not resolve “backend”.
