Description
Abstract
This talk will discuss the challenges of developing, testing, deploying and scaling Dockerize apps.
Intro to Micro-Services and Docker Containers
The focus is on Flask based Python micro-services, however most of the concepts work for web apps and services written in Django or Pyramid. The talk starts with a quick intro or refresher to micro-services (SOA) and Docker concepts such as images, and containers.
Developing + Testing with Docker
Next section is a quick overview of developing and debugging Docker images.
More details are available in the documentation for Docker, but a few basic
example will be given. The talk gets into the specifics of what is needed to
host a WSGI app in Docker, and some best practices for Python apps which differ
when working with a container environment vs in a normal development
environment.
Deployment + Scaling
The next section deals with deploying micro-services. It touches upon the many problems you need to consider when running multiple services, namely: dependencies, monitoring and load balancing. Also the talk touches upon the additional complexity added by rolling deploys and rollbacks/fail-overs.
Lessons Learned
The final section presents a few key takeaways for the audience to consider when using Docker to run Python web apps in production.
