in cluster with docker-compose cannot login to web ui

EventStoreDB

I have setup 3 docker containers with eventstore with the following docker-comppose extract:
…
eventstore:

image: eventstore/eventstore

ports:

  • 1112:1112

  • 1113:1113

  • 2112:2112

  • 2113:2113

environment:

  • EVENTSTORE_CLUSTER_SIZE=3

  • EVENTSTORE_CLUSTER_DNS=172.20.0.1

networks:

  • esnet

  • default

eventstore1:

image: eventstore/eventstore

environment:

  • EVENTSTORE_CLUSTER_SIZE=3

  • EVENTSTORE_CLUSTER_DNS=172.20.0.1

networks:

  • esnet

eventstore2:

image: eventstore/eventstore

environment:

  • EVENTSTORE_CLUSTER_SIZE=3

  • EVENTSTORE_CLUSTER_DNS=172.20.0.1

networks:

  • esnet

networks:

default:

esnet:

driver: bridge

ipam:

driver: default

config:

  • subnet: 172.20.0.0/16

Navigating to http://localhost:2113/web in the browser opens the login page, but after entering default credentials, it is denied and the browser also show its login dialog. Credentials are not accepted. What could be wrong here. Having only one node in docker works fine with web ui.
