Whaler haproxy plugin

This plugin install haproxy as a load balancer for whaler. Plugin is useful when you need deploy multiple applications on one server, or use complex application publishing.

Install

whaler plugins:install whaler-haproxy-plugin

Dnsmasq

The only reason why dnsmasq is needed is to point all the domains *.whaler.lh to machine where docker is installed. On linux it is 127.0.0.1, on windows and mac it's virtual machines's IP.

NB! Dnsmasq step is pure optional, but then you need manually add records to /etc/hosts file.

Install dnsmasq:

sudo apt-get install dnsmasq

Update config file /etc/dnsmasq.conf with following line:

address=/whaler.lh/127.0.0.1

NB! Don't forget to replace 127.0.0.1 with virtual machine ip, if not on linux.

How to avoid conflicts between dnsmasq and systemd-resolved

Update config file /etc/dnsmasq.conf with following lines:

server=8.8.8.8
server=8.8.4.4
# ...

Run this commands:

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo sed -i 's/\[main\]/\[main\]\ndns=dnsmasq/g' /etc/NetworkManager/NetworkManager.conf
sudo systemctl restart NetworkManager
sudo rm /etc/resolv.conf
sudo ln -s /var/run/NetworkManager/resolv.conf /etc/resolv.conf
sudo systemctl restart dnsmasq
