London Community Summit 2016 - Habitat
This document discusses Application Automation with Habitat. It provides an overview of Habitat's technology including the plan artifact depot, build service, supervisor, and artifact distribution servers. It then summarizes some new features and updates to Habitat since its initial launch in 2016, including package search from the command line, improved proxy support, faster configuration iteration, better behavior for root/non-root users via sudo, easier upgrading on Mac, and process updates around continuous deployment and a distributed build service. It invites contributors to participate in Hacktoberfest and help shape Habitat's direction.

- 14. Improved Proxy Support •Supports $http_proxy, $https_proxy, $no_proxy environment variables • Basic authentication • Propagate into Studios
- 15. Iterate Service ConfigurationsQuicker using –config-from • Faster iteration of configuration templates during plan development • $ hab start yourorigin/yourpackage --config-from /path/to/config • Intended only for development
- 16. Improved Root/Non-Root Behaviorvia sudo • Drop the need to prefix most hab commands with sudo • Entering a Studio with sudo detects user’s key cache (not root’s) • $ hab setup; sudo hab studio enter • Future release will “auto-sudo” when using Studio subcommands
- 17. Better Mac Docker/StudioUpgrading • Mac uses a Docker image for Linux Studio • Runs Docker image with same version as hab CLI • On upgrading hab CLI, new Docker image automatically pulled
- 18. Process: Release TrainModel • Userland tooling: hab CLI, Supervisor, Director • Every second Thursday, cut from master • Typically a minor version revision • Features ship when ready and early features will hide behind feature flags
- 19. Process: (Upcoming) Continuous Deployment •Platform infrastructure: web site, Depot, Builder • Packages built off master and published to Depot • Platform upgrades when new packages publish • Decoupled release from userland tooling
- 20. Builder: A DistributedBuild Service • Micro service architecture, built with Habitat in mind • Habitat runs on Habitat • Upcoming: early access to build a package on the platform via feature flag/invite • Upcoming: building packages on pushes to GitHub • Upcoming: dependent package rebuilding • More details: “Habitat 301: Building Habitats” ChefConf 2016 Talk by Jamie Winsor
- 21. Expanding Horizons: Windows •Bring Mac Habitat experience to Windows • Building hab CLI • Upcoming: ship first hab packages for Windows • Upcoming: native Windows Habitat packages • Upcoming: Supervisor running on Windows
- 22. Contribute to “Habtoberfest”! •Habitat participating in Digital Ocean’s Hacktoberfest event • Runs October 1st through 31st • Make 4 pull requests (on any FOSS project), earn a limited edition Hacktoberfest T-shirt • Habitat repo has “Hacktoberfest” tagged issues • http://hacktoberfest.digitalocean.com

Editor's Notes
- #11 And that’s basically how it comes together. You, as a user, make plans that get turned into artifacts that are accessible via a depot. Supervisors then pick up and run those artifacts on a variety of platforms and are equipped to make decisions about how they’re configured as they are starting up their child process (i.e. at runtime). Your applications can act autonomously and are equipped to make decisions about how they manage and update themselves. They intercommunicate securely and the supervisors all constantly watch, update, and share the status of the entire cluster with each other. Bam! That’s how Habitat works.
