Hi all,
I've been fighting this one for a while. adding N containers to a custom
network. host1 starts services that listen on 50070. on host1 I can
'telnet host1.dev 50070' and it works. host2 is connected to the same
'dev' network, but from host2 connection is refused to host1 on 50070, but
ping to host1 works fine. I've tried exposing/publishing ports. Although
its my understanding inter-container communication on a shared network
doesn't need ports exposed as a requirement.
host: linux mint - 4.4.0-62-generic #83-Ubuntu
ansible 2.2.1.0
Docker version 1.12.3, build 6b644ec
relevant files:
tasks:
- name: Create dev cluster network
docker_network:
name: dev
- name: Start docker node images
docker_container:
image: "test/image"
name: "host{{ item }}"
hostname: "host{{ item }}.dev"
state: started
privileged: true
interactive: yes
restart_policy: always
exposed_ports: "{{ node_ports }}"
#published_ports: "{{ node_ports }}"
networks:
- name: dev
with_sequence: count=3
I have another container started the same way that starts a service on
8080, and all containers can connect to that node/port fine. I'm guessing
it has to do with how each service is starting, but i do not control how
services are started. any ideas...?
Thanks
