Packages and quick start guide

GLB Director's components are packaged and ready to use along with a compatible DPDK version for Debian Jessie and Debian Stretch.

Installing the apt sources

An unofficial DPDK release apt source is provided which provides a compatible DPDK version to use with GLB director - currently DPDK 17.11.1-6:

curl -s https://packagecloud.io/install/repositories/github/unofficial-dpdk-stable/script.deb.sh | sudo bash

The GLB packages themselves are also available as an apt source:

curl -s https://packagecloud.io/install/repositories/github/glb-director/script.deb.sh | sudo bash

Director tier: `glb-director`

The main glb-director DPDK application takes packets destined to a GLB IP and encapsulates them over a tunnel to one of the configured backend proxy servers.

Installation on Debian:

sudo apt install glb-director

The following configuration files need to be adjusted, see glb-director configuration and GLB forwarding table configuration for more information:

/etc/default/glb-director - Configuration around the DPDK EAL runtime and other similar configuration options, used by systemd.
/etc/glb/director.conf - The default location for the configuration of how the director processes packets on CPU cores and on ports/NICs.
/etc/glb/forwarding_table.json - The default location for the forwarding table when healthchecking is not used.

The glb-director runs with systemd under the glb-director.service unit.

Director tier: `glb-healthcheck`

The glb-healthcheck application runs tunnel and HTTP healthchecks on a source GLB forwarding table, writing out a new table that glb-director can consume that takes into account health state of backend proxy servers.

Installation on Debian:

sudo apt install glb-healthcheck

To configure the healthchecker to work with glb-director, the /etc/default/glb-director will need to be updated to reflect the /etc/glb/forwarding_table.checked.bin version.

The following files are relevant to configuring the healthchecker itself, see GLB forwarding table configuration for more information:

/etc/glb/healthcheck.conf - The default location for the configuration of how the healthchecker performs its functions.
/etc/glb/forwarding_table.src.json - The default location for the forwarding table when healthchecking is used.
/etc/glb/forwarding_table.checked.json - Auto-generated by glb-healthcheck.

The glb-healthcheck runs with systemd under the glb-healthcheck.service unit.

Proxy tier: `glb-redirect-iptables-dkms`

The glb-redirect-iptables-dkms package uses DKMS to create and maintain an iptables module for GLB purposes that works on the currently running kernel.

Installation on Debian:

sudo apt install glb-redirect-iptables-dkms

This package provides the GLB-REDIRECT iptables target, see Backend Proxy Setup for more information on configuring proxy tier servers including usage of this iptables module.
