Installing vitess

First of we need the registry and mysql server installed so we can keep track on which services are available, download new services and also run the actual database.

sudo apt install -y default-mysql-server default-mysql-client etcd curl

Before we start this POC we disable the default services as we will be setting up our own.

Installing i3-gaps

Dependencies

i3-gaps has some packages that are required for it to work so install these things:

sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool automake

You also need to install libxcb-xrm-dev, but I got Unable to locate package libxcb-xrm-dev when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:

mkdir tmp

	# Change these variables as necessary.
	main_package_path = ./cmd/example
	binary_name = example
