sending udp broadcast from a docker container

Question

I\'m having a few docker containers (Using docker-compose and a single network - network-sol)

One of the containers is a Spring Boot application

Answer 1

You should either run the service defined in your docker-compose.yml file with network_mode: host.

Alternatively you can publish the port of the container you intended to communicate with by publishing it using the following configuration. Note that the /udp is required for UDP communication to work.

service:
  ports:
    - "8080:8080/udp"
