Consul share network from docker

Question

There is consul server in docker.

  vote-consul-server:
    image: consul:1.7.2
    environment:
      CONSUL_BIND_INTERFACE: eth0
    ports:
      - "${CONSUL_PORT}:8500"

It generates hosts for registred applications. The main problem is that anothers applications can't communicate between each other if they are not in docker.

For example: I have config-service (docker with consul), user-service(IDE). When user-service starts, it asks for configurations from config-server, but consul gives not correct link (available only in docker network).

How to publish all links from consul(docker)?

Answer 1

Since every container has own IP and may have own network, you can try to use host networking:

docker run --rm -d --network host --name vote-consul-server

For more details, see host networking tutorial.

Also, you can learn about networking from the container’s point of view
