Configure announced addresses

You need to configure the announceAddresses settings if the following statements are both true:

  • there is NAT between the discovery helper node and your other nodes, and
  • one (or more) of your nodes is a Docker node, and the Actyx container is not running with the --network=host option

In this case, you have to manually configure the address of your node's host in the announceAddress property in the node settings:

announceAddress: # Manually configured addresses to announce
  - /ip4/192.168.1.101/tcp/4001
  # These must be multiaddresses, i.e. ip4/<YOUR_IP>/tcp/4001

You can configure it by using the Actyx CLI or the Node Manager. The following examples assume that the IP address of your Docker node is 192.168.2.10:

You can use the output from above and ax settings set to configure it:

ax settings set /swarm/announceAddresses [/ip4/192.168.2.10/tcp/4001] localhost
