Requirements

To build you will need the Angular CLI installed

To run you will need Node.js installed

To work with Docker you will need Docker installed

This project was generated with Angular CLI version 1.5.0.

Getting Started

To Build

ng build

To start the node server

node server.js $HOSTNAME

Docker

To pull the Docker image from the Pintail.ai Dockerhub

docker pull pintailai/pintail-whoami:0.0.1

To run the Offical Version

docker run -d --rm -p 80:80 --name pintail-whoami pintailai/pintail-whoami:0.0.1

To build the image

docker build -t pintail-whoami .

To run your local build

docker run -d --rm -p 80:80 --name pintail-whoami pintail-whoami

Docker Compose

The docker-compose.yml file is designed to explain what Docker compose is and how it works. It simply spins up two containers by default the pintail whoami image and jwilder/nginx-proxy. The nginx proxy is designed to automatically route and load balence to docker images running on a network.

To start up the images using Docker compose docker-compose up -d

To see the images running docker-compose ps

To see the logs of all the containers Docker compose started docker-compose logs -f

Once you can see that the images started up correctly go to localhost on you machine to see pintail-whoami running

To scale up the number of pintail-whoami containers running docker-compose up --scale pintail-whoami=2 -d

After you have scaled up the number of pintail-whoami containers running greater than one you can refresh localhost and you should the ID beneath "Welcome to the Pintail.ai Docker Example!" change. This indicates that the nginx-proxy is forwarding you to different Docker containers!
