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

I posted several talks about compiling PHP from source, but everyone was trying to convince me that a package manager like Homebrew was a more convenient way to install.

The purpose of Homebrew is simple: a package manager for macOS that will allow you to set up and install common packages easily and allows you to update frequently using simple commands.

I used a clean installation of macOS Sierra to ensure all steps could be recorded and tested. In most cases you already have done work on your Mac, so chances are you can skip a few steps in this tutorial.

Apache and PHP with homebrew

I’ve made this according to the installation instructions given on GetGrav.
