How I can add new node to elliptics group? (autodiscovery)

[revengel]

I have 3 elliptics containers:

  elliptics11:
    image: "elliptics:latest"
    environment:
      ELLIPTICS_GROUP: 1
      ELLIPTICS_REMOTE_CONNECT: "elliptics12:1025:2;elliptics13:1025:2;"
      ELLIPTICS_ADDRESSES: "elliptics11:1025:2-1"

  elliptics12:
    image: "elliptics:latest"
    environment:
      ELLIPTICS_GROUP: 1
      ELLIPTICS_REMOTE_CONNECT: "elliptics11:1025:2;elliptics13:1025:2"
      ELLIPTICS_ADDRESSES: "elliptics12:1025:2-1"

  elliptics13:
    image: "elliptics:latest"
    environment:
      ELLIPTICS_GROUP: 1
      ELLIPTICS_REMOTE_CONNECT: "elliptics11:1025:2;elliptics12:1025:2"
      ELLIPTICS_ADDRESSES: "elliptics13:1025:2-1"

Elliptics config:

{
  "logger": {
    "level": "info",
    "frontends": [
      {
        "formatter": {

      }
    ]
  },

  },

    }
  ]
}

How I can use 'autodiscovery' for quick and easy adding node to the elliptics group?

[bioothod]

Please do not use autodiscovery, it has weird issues when there are multiple interfaces because of ipv4 multicast selections, so it was disabled in the current versions

Thanks.

After adding elliptics node to the group I must add its address to remotes section of the every node in the group?

If all other nodes can reach the node whose config you have updated, you may skip updating configs for other nodes.
