Abstract

This is a look at managing application deployment with an indipendent packaging system (pkgsrc). Let’s Compare and contrast with “traditional” mechanisms like .deb and .rpms, tarballs, deployment tools (Salt, Capistrano, Vlad, Fabric), and containers (Jails, Rocket, Docker, etc). In particular we’ll look at the autonomy gained from decoupling the application stack from the operating system packages with pkgsrc’s ability to have multiple parallel installation bases all running different versions on the same system.

Outline

  • Introduction
    • What are we talking about
    • Who am I/What I do
  • What’s the problem?
    • Deploying applications
    • Conflicting libraries
    • Conflicting versions of the applicaiton
    • Conflicting versions of the runtime (Java, Python, Ruby, Node.js, etc)
    • Roll-back
  • Approaches to avoid the problem
    • Docker/Racket/Containers
    • Immutable Infrastructure
    • Private Forks
    • Refusing to upgrade/migrate
  • What the solution really looks like
    • What is pkgsrc
    • What are possible alternatives
