Unable to Join Cluster

[psybernoid]

New Setup, building with 3 nodes.

First node is running, only changes made is to the admin password. Everything else is default.

When adding a second node, the logs of the second instance read:

{"level":"info","ts":1719984521.414721,"logger":"instance","msg":"Gravity starting","instance":"grav2","version":"0.9.0-af608cc1","instance":"grav2","version":"0.9.0-af608cc1"}

Relevant compose files:

Node#1

services:
  grav1:
    hostname: grav1
    image: ghcr.io/beryju/gravity:stable
    restart: unless-stopped
    container_name: grav1
    network_mode: host
    volumes:
      - /docker/gravity/data:/data
    logging:
      driver: json-file
      options:
        max-size: "10m"
        max-file: "3"

Node#2

services:
  grav2:
    hostname: grav2
    image: ghcr.io/beryju/gravity:stable
    restart: unless-stopped
    container_name: grav2

I found that if you remove the BOOTSTRAP_ROLES: dns line, it actually attempts the join.

Thanks. That worked

I had the same issue .. I think you need at least ETCD as I got a 3rd node running with just that
