rpi-compose-haproxy

A sample web app on rasberry pi with HAproxy and docker-compose

Based on hypriot's howto

Notes:

docker was installed on a rasbian based system with the following:

$ wget http://downloads.hypriot.com/docker-hypriot_1.8.2-1_armhf.deb
dpkg -i docker-hypriot_1.8.2-1_armhf.deb

docker-compose was installed with the following command:

$ sudo sh -c "curl -L https://github.com/hypriot/compose/releases/download/1.2.0-raspbian/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose; chmod +x /usr/local/bin/docker-compose"

TODO

• Use consul for service discovery
• Use registrator for service registration
• Use consul-template to update haproxy.cfg
• Get haproxy to reload cfg file change
• Test service increase/decrease in circleCi
• Add redis service
• Add redis replication
• Migrate into docker swarm
