Sample Flask App in a Docker Container

Description

A very basic Flask app in a Docker container. I've used it to demonstrate Mesos + Marathon + Haproxy docker scaling.

Build

• Method 1
  • Pull the image from the docker registry (docker hub) and rename it

    $> docker pull sbobylev/docker_sample_flask_app
    $> docker tag sbobylev/docker_sample_flask_app docker_sample_flask_app
    $> docker rmi sbobylev/docker_sample_flask_app
    

• Method 2
  • Build the image from scratch

    $> git clone https://github.com/sbobylev/docker_sample_flask_app.git
    $> cd docker_sample_flask_app
    $> docker build --rm=true -t docker_sample_flask_app .
    

Run

$> docker run -p 8080:8080 -d sbobylev/docker_sample_flask_app

$> docker ps
