Improved Proxy Support• Supports $http_proxy, $https_proxy, $no_proxy

environment variables• Basic authentication• Propagate into Studios

Iterate Service Configurations Quicker using–config-from• Faster iteration of configuration templates during plan

development• $ hab start yourorigin/yourpackage --config-from

/path/to/config• Intended only for development

Improved Root/Non-Root Behavior via 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

Better Mac Docker/Studio Upgrading• 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

Process: Release Train Model• 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

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

Builder: A Distributed Build 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

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
