Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

TCP port 2377 for cluster management & raft sync communications
TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
UDP port 4789 for "data plane" VXLAN overlay network traffic
IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option

AWS Security Group Example

If you've deployed an app based on PHP 5.3 and MySQL using PHP's mysqli, then you may have run into some issues because the mysqlnd driver for PHP is not installed. This is required for some mysqli features like get_result().

You may run into some of the following isseus:

Fatal error: Call to undefined method mysqli_stmt::get_result()

Fatal error: Call to undefined function mysqli_stmt_get_result()

Fatal error: Call to unefined method mysqli_result::fetch_all()
