swarm install alertmanager cluster failed

[like-inspur]

docker version: 17.09.1-ce，alertmanager image version: prom/alertmanager:v0.15.0-rc.
I config docker stack yml referenced alertmanager#high-availability, include three nodes three services
Three alertmanager are alike, alertmanager1 config is like this:
alertmanager1:
　image: prom/alertmanager:v0.15.0-rc.1
　volumes:
　　- /monitor/alertmanager:/alertmanager
　　- /etc/localtime:/etc/localtime:ro
　command: --config.file=/etc/alertmanager/config.yml --storage.path=/alertmanager --cluster.listen-address=0.0.0.0:9094 --cluster.peer=alertmanager2:9094 --cluster.peer=alertmanager3:9094
　ports:
　　 - target: 9093
　　published: 9093
　　protocol: tcp
　　mode: host
　configs:
　　 - source: alertmanager_config
　　target: /etc/alertmanager/config.yml
　　mode: 0664
　networks:
　　 - monitor
I found peers is only one that output from url, container log is like this:

It's probably related to #1307

Please format your issue next time.

I use overlay network, so container has overlay and docker_gwbridge addresses. I found alertmanager cluster peers address is docker_gwbridge, not the real overlay address that containers can connect.

this is a usage question, and would be better directed to the users mailing list [email protected]
