You don't need to know which nodes are running the tasks; connecting to port 8080 on any of the 10 nodes connects you to one of the three nginx tasks. You can test this using curl. The following example assumes that localhost is one of the swarm nodes. If this is not the case, or localhost does not resolve to an IP address on your host, substitute the host's IP address or resolvable host name.\n\nThe HTML output is truncated\n\nBounded code example (external data; do not execute automatically):\n```console\n$ curl localhost:8080\n\n\n\n\nWelcome to nginx!\n...truncated...\n\n```\n\nSubsequent connections may be routed to the same swarm node or a different one.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
