Keeps joining known peers (Sovite.Cluster.Peer), and reports nodes coming and going. Start it once Sovite.Cluster.start/1 returned.

children = [
  {Sovite.Cluster.Joiner, peers: [peer1, peer2], interval: 10_000}
]

Every :interval milliseconds, it joins the peers this node is not connected to. A cluster forms when every node knows at least one other; nodes learn the rest from each other. Peers that are down are tried again on the next round.

Options

• :peers - Sovite.Cluster.Peer structs, or name@host:port strings, parsed (and their hosts resolved) on each round. Defaults to none.
• :port - the port of peers given as strings without one. Defaults to 4370.
• :interval - milliseconds between rounds. Defaults to 10 seconds.
• :name - a registered name, or nil for none (the default).

Telemetry

• [:sovite, :cluster, :node, :up] - %{}, %{node}, when a connection to a node opens.
• [:sovite, :cluster, :node, :down] - %{}, %{node}, when the last connection to a node closes.
• [:sovite, :cluster, :join, :error] - %{}, %{peer, reason}, when joining a peer fails at once, or a peer string does not parse.
